Let’s get started!

What You’ll Need

To make this Baked Spinach Chicken Spaghetti recipe a success, you’ll need a few essential tools and ingredients. Having everything prepared before you start cooking will make the process smooth and enjoyable. Below, we’ll go over the kitchen equipment and ingredients that are crucial for creating this dish.

Kitchen Equipment

Large Pot:
The large pot is essential for boiling the spaghetti. Choosing a pot that gives the pasta enough space to cook evenly is key to achieving that perfect al dente texture. Whole wheat spaghetti is a great choice if you’re looking for a healthier alternative.
Skillet:
A sturdy skillet is necessary for cooking the chicken and spinach. A non-stick or cast-iron skillet works well for evenly browning the chicken and ensuring the spinach wilts perfectly without sticking.
Baking Dish:
A 9×13 inch baking dish is ideal for assembling and baking the final dish. This size is perfect for ensuring that the spaghetti is spread evenly and that the cheesy topping melts and browns beautifully.

Cheese Grater:
Freshly grated cheese melts more smoothly and tastes better than pre-shredded options. A good-quality cheese grater will help you quickly grate mozzarella and Parmesan for that creamy sauce and golden topping.

Essential Ingredients

Spaghetti:
The foundation of this dish is spaghetti. You can opt for traditional white pasta or whole wheat for added fiber. The key is to cook it until al dente, as it will continue cooking in the oven and absorb the flavors of the creamy sauce.
Chicken:
Boneless, skinless chicken breasts or thighs are best for this recipe. They cook quickly and shred easily, making them perfect for incorporating into the creamy spinach mixture.

Spinach:
Fresh spinach is preferred for this recipe, but frozen spinach works as well. If using frozen, make sure to thaw and drain it thoroughly to remove excess moisture, which could water down the sauce.
Cheese:
This dish is all about the cheese. You’ll need mozzarella for that gooey, stretchy texture, Parmesan for a sharp, nutty flavor, and cream cheese to bring the sauce together in a smooth, velvety consistency.
Garlic:
Freshly minced garlic adds a robust flavor to the dish. It’s sautéed with the chicken and spinach to infuse the entire mixture with a fragrant, savory aroma.

Olive Oil:
A good quality olive oil is essential for sautéing the garlic, chicken, and spinach. It adds a subtle richness and helps everything cook evenly without sticking.
Cream:
To achieve that luxurious, creamy sauce, you’ll need some cream. It not only adds richness but also helps to blend the cheese into a smooth, cohesive sauce that coats every strand of spaghetti.

Why These Ingredients Work Together

The combination of these ingredients creates a balanced and flavorful dish. The spaghetti provides a hearty base, while the chicken adds protein. Spinach brings a dose of greens, and the trio of cheeses ensures the dish is creamy and indulgent. Garlic and olive oil enhance the flavor profile, making every bite delicious.

Ingredients

Now that you’re familiar with the essential equipment and ingredients, let’s dive into the specifics of what you’ll need to create this delicious Baked Spinach Chicken Spaghetti. Below is a detailed list of ingredients along with their quantities. This section will also include some helpful tips to ensure each component of the dish shines.

Ingredient List

12 oz spaghetti
The foundation of the dish. You can choose regular or whole wheat spaghetti depending on your dietary preferences. Whole wheat offers more fiber and nutrients, making it a healthier option.
2 cups cooked chicken, shredded
Boneless, skinless chicken breasts or thighs work best here. If you’re in a hurry, you can use pre-cooked rotisserie chicken to save time. Ensure the chicken is shredded into bite-sized pieces for easy mixing and even distribution throughout the dish.

10 oz fresh spinach (or 1 package frozen, thawed, and drained)
Fresh spinach adds vibrant color and nutrients, but frozen spinach is a convenient alternative. If using frozen, make sure to thaw it completely and squeeze out any excess water to prevent the dish from becoming too watery.
1 cup mozzarella cheese, shredded
Mozzarella is the star of the cheesy topping. Its mild flavor and gooey texture when melted make it a perfect choice for this recipe. Freshly shredded mozzarella melts better and provides a smoother texture.
1/2 cup Parmesan cheese, grated
Parmesan adds a sharp, salty kick that complements the milder mozzarella. Grate it fresh to get the best flavor and texture.

1/2 cup cream cheese
Cream cheese is the secret ingredient for a creamy, velvety sauce. It melts beautifully and helps bind the other cheeses into a smooth, cohesive mixture that coats the spaghetti perfectly.
2 cloves garlic, minced
Fresh garlic adds a wonderful depth of flavor to the dish. Mince the garlic finely to ensure it spreads evenly through the chicken and spinach mixture.
2 tbsp olive oil
Olive oil is used for sautéing the garlic, chicken, and spinach. It adds a subtle richness and helps to prevent sticking during the cooking process.

Salt and pepper to taste
Simple seasonings like salt and pepper are crucial to bringing out the flavors of the other ingredients. Season the dish at various stages to ensure even flavor distribution.

Ingredient Preparation Tips

Spaghetti:
Cook the spaghetti until al dente, following the package instructions. Remember that it will continue cooking in the oven, so avoid overcooking it during boiling. After draining, toss it with a little olive oil to prevent sticking.
Chicken:
If you’re cooking the chicken specifically for this dish, season it lightly with salt and pepper before cooking. Shred it using two forks or chop it into small pieces to make sure it mixes well with the spinach and cheese sauce.

Spinach:
If using fresh spinach, give it a quick rinse and pat it dry before sautéing. For frozen spinach, thaw it completely and press out as much moisture as possible using paper towels or a clean kitchen cloth.
Cheeses:
Shred and grate the cheeses yourself if possible. Pre-shredded cheese often contains anti-caking agents that can prevent it from melting smoothly, which is key to achieving a creamy sauce and topping.

Why These Ingredients Are Important

Each ingredient in this list plays a crucial role in building the flavors and textures of the Baked Spinach Chicken Spaghetti. The combination of pasta, chicken, and spinach creates a hearty base, while the mix of cheeses ensures the dish is rich and satisfying. Garlic and olive oil provide a savory backdrop that ties everything together.

Instructions

Making Baked Spinach Chicken Spaghetti is straightforward, and by following these step-by-step instructions, you’ll end up with a dish that’s both flavorful and visually appealing. This section will guide you through the entire process, from cooking the pasta to baking the final dish.

Step 1: Prepare the Spaghetti

Cook the Spaghetti:
Begin by bringing a large pot of salted water to a boil. Once the water is boiling, add the spaghetti and cook according to the package instructions until it reaches an al dente texture. This usually takes around 8 to 10 minutes. Al dente pasta should be tender but still firm to the bite, which is ideal since it will continue cooking in the oven.
Drain and Set Aside:
Once the spaghetti is cooked, drain it in a colander and give it a quick rinse with cold water to stop the cooking process. Toss the drained spaghetti with a drizzle of olive oil to prevent it from sticking together, then set it aside while you prepare the rest of the ingredients.

Step 2: Cook the Chicken and Spinach

Sauté the Garlic:
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Once the oil is hot, add the minced garlic and sauté for about 1 minute, or until it becomes fragrant. Be careful not to let the garlic burn, as it can turn bitter.
Add the Chicken:
Next, add the shredded chicken to the skillet. Stir it well to combine with the garlic. Cook the chicken for about 5 minutes, or until it’s lightly browned and heated through. This step ensures the chicken absorbs the garlicky flavor and stays juicy.
Incorporate the Spinach:
If you’re using fresh spinach, add it to the skillet in batches, stirring constantly until it wilts down. If you’re using thawed and drained frozen spinach, add it all at once and cook for another 2-3 minutes, until it’s evenly mixed with the chicken. The spinach should be fully wilted and integrated with the chicken at this point.

Step 3: Make the Cheese Sauce

Add the Cream Cheese:
Lower the heat to medium-low and add the cream cheese to the skillet. Stir continuously until the cream cheese melts and combines with the chicken and spinach. The mixture should start to come together into a creamy sauce.
Mix in the Mozzarella and Parmesan:
Once the cream cheese is fully melted, gradually add in half of the shredded mozzarella and Parmesan cheeses. Stir until the cheeses are completely melted and the sauce is smooth. This cheesy sauce will coat the spaghetti and create a rich, decadent flavor.

Step 4: Assemble the Dish

Preheat the Oven:
Before assembling the dish, preheat your oven to 350°F (175°C). This allows the oven to reach the correct temperature by the time you’re ready to bake.

Combine Ingredients in the Baking Dish:
In a 9×13 inch baking dish, add the cooked spaghetti, then pour the chicken and spinach mixture over the top. Use a pair of tongs or a large spoon to gently mix everything together until the spaghetti is evenly coated with the sauce and the chicken and spinach are well distributed.
Top with Remaining Cheese:
After mixing, spread the remaining mozzarella and Parmesan cheeses evenly over the top of the spaghetti mixture. This will create a golden, bubbly topping as it bakes.

Step 5: Bake

Bake the Dish:
Place the baking dish in the preheated oven and bake for 20-25 minutes. The dish is ready when the cheese on top is melted, bubbly, and golden brown. If you prefer a crispier topping, you can turn on the broiler for the last 2-3 minutes of baking, keeping a close eye to prevent burning.

Serve and Enjoy:
Once baked, remove the dish from the oven and let it cool for a few minutes before serving. This allows the flavors to meld and makes it easier to serve. Serve hot, and enjoy the creamy, cheesy goodness of your Baked Spinach Chicken Spaghetti.

A standard portion size is about 1 ½ cups per person, which provides a balanced serving of protein, carbohydrates, and fat. This recipe typically serves 6 people, but portions can be adjusted based on your needs.

Storage Tips

Refrigeration:
If you have leftovers, let the dish cool completely before transferring it to an airtight container. Store the leftovers in the refrigerator for up to 3 days. To reheat, place the desired portion in an oven-safe dish and warm it at 350°F until heated through. Alternatively, you can reheat it in the microwave, but be aware that the cheese might not melt as evenly as it would in the oven.

Freezing:
This dish freezes well, making it a great option for meal prep. To freeze, allow the baked spaghetti to cool completely, then transfer it to a freezer-safe container. It can be stored in the freezer for up to 3 months. When ready to eat, thaw it in the refrigerator overnight, then bake at 350°F until thoroughly heated. You might want to add a fresh layer of cheese on top before reheating to ensure a bubbly, golden finish.
Portion-Freezing:
If you want to freeze individual portions, divide the cooled spaghetti bake into single-serving sizes and place them in small, freezer-safe containers. This method makes it easy to grab just the amount you need, whether for a quick lunch or a solo dinner.

Avoiding Common Storage Mistakes

Don’t Store Warm:
Always allow the dish to cool to room temperature before refrigerating or freezing. Storing it while still warm can cause condensation, which leads to soggy pasta and potentially faster spoilage.

Use Proper Containers:
Use airtight containers to store leftovers to prevent the dish from absorbing any odors from the fridge. For freezing, make sure the containers are freezer-safe to avoid freezer burn.
Labeling:
If freezing, don’t forget to label the container with the date. This helps you keep track of how long it has been stored, ensuring you use it while it’s still at its best quality.

Variations

One of the best things about Baked Spinach Chicken Spaghetti is its versatility. This dish is highly customizable, allowing you to experiment with different flavors, ingredients, and textures. Below are some creative variations to suit various tastes and dietary preferences.

1. Protein Alternatives

Turkey or Ham:
If you have leftover turkey or ham from a holiday meal, they make excellent substitutes for chicken. Turkey provides a slightly richer flavor, while ham adds a savory, smoky element that pairs well with the creamy sauce. Simply shred or chop the meat and use it in place of chicken for a delightful twist on the classic recipe.
Ground Beef or Sausage:
For a heartier version, try using ground beef or Italian sausage instead of chicken. Brown the meat in the skillet with the garlic before adding the spinach. The robust flavors of beef or sausage create a richer, more indulgent dish. This variation is perfect for those who enjoy a more substantial, meat-forward meal.
Shrimp:
For a seafood variation, substitute the chicken with shrimp. Sauté the shrimp until they turn pink and are cooked through, then proceed with the recipe as usual. The shrimp adds a delicate sweetness that complements the richness of the cheese sauce and the slight bitterness of the spinach.

2. Veggie Boost

Add Mushrooms or Bell Peppers:
Incorporating additional vegetables like mushrooms or bell peppers not only enhances the nutritional value but also adds depth to the dish. Sauté sliced mushrooms or diced bell peppers with the spinach for a burst of flavor and texture. The mushrooms add an earthy note, while bell peppers provide a sweet crunch that pairs beautifully with the creamy sauce.
Zucchini or Broccoli:
Zucchini and broccoli are other great options for adding more vegetables to this dish. Slice zucchini into thin rounds or chop broccoli into small florets and sauté them with the spinach. These vegetables add a fresh, vibrant element that lightens up the richness of the cheese and cream.
Sun-Dried Tomatoes:
For a burst of tangy sweetness, mix in some chopped sun-dried tomatoes. Their intense flavor adds a delightful contrast to the creamy sauce and pairs well with the spinach and chicken. You can stir them in with the chicken and spinach for an extra layer of flavor.

3. Different Cheeses

Cheddar or Gouda:
If you’re looking to switch up the flavor profile, try using sharp cheddar or gouda instead of mozzarella. Cheddar brings a bold, tangy taste, while gouda adds a slightly sweet, smoky flavor. Both melt beautifully and create a slightly different but equally delicious creamy sauce.
Swiss or Monterey Jack:
Swiss cheese offers a nutty, slightly sweet flavor that pairs well with the spinach and chicken. Monterey Jack, on the other hand, is mild and creamy, making it a good alternative if you want a less intense cheese flavor. These cheeses can be used in place of or in combination with mozzarella for a unique twist.
Blue Cheese or Feta:
For those who enjoy bold, tangy flavors, adding blue cheese or feta can take this dish to the next level. Crumble these cheeses into the sauce for a punch of flavor that cuts through the richness of the cream and other cheeses. This variation works particularly well with the spinach, as the slight bitterness of the greens balances the sharpness of these cheeses.

4. Gluten-Free and Low-Carb Options

Gluten-Free Pasta:
To make this dish gluten-free, simply substitute the regular spaghetti with your favorite gluten-free pasta. Many gluten-free pastas are now available in various grains like quinoa, rice, or chickpeas, providing similar textures and flavors to traditional pasta.
Zucchini Noodles (Zoodles):
For a low-carb alternative, try using zucchini noodles in place of spaghetti. Zoodles have a light texture and mild flavor, making them a great vehicle for the creamy sauce without the extra carbs. Just be sure to sauté the zoodles briefly before mixing them with the sauce to prevent them from becoming too watery.
Spaghetti Squash:
Another excellent low-carb option is spaghetti squash. When roasted, the flesh of the squash pulls apart into spaghetti-like strands. It has a slightly sweet flavor that pairs beautifully with the creamy, cheesy sauce. This alternative is perfect for those looking to cut back on carbs without sacrificing the comfort of a pasta dish.

Frequently Asked Questions (FAQs)

When making Baked Spinach Chicken Spaghetti, you may have a few questions about substitutions, ingredient choices, and cooking techniques. In this section, we’ll address some of the most common inquiries to help ensure your dish turns out perfectly every time.

1. Can I use frozen spinach instead of fresh spinach for baked spinach chicken spaghetti?

Yes, you can absolutely use frozen spinach in this recipe. In fact, frozen spinach is a convenient option that’s available year-round. To use frozen spinach, make sure to thaw it completely and then drain it well to remove any excess moisture. Squeezing the spinach in a clean kitchen towel or pressing it with paper towels can help eliminate the water. This step is crucial because excess moisture can water down the sauce, making the dish less creamy.

2. What types of cheese work best for topping baked spinach chicken spaghetti?

Mozzarella and Parmesan are classic choices for topping Baked Spinach Chicken Spaghetti. Mozzarella melts beautifully and gives the dish that gooey, stretchy texture that’s so satisfying, while Parmesan adds a sharp, nutty flavor and helps create a golden-brown crust. If you want to experiment with different flavors, you can also use cheeses like cheddar, gouda, or Monterey Jack. Each of these cheeses offers a unique taste that can complement the spinach and chicken in delicious ways.

3. Can I make this dish ahead of time and bake it later?

Yes, Baked Spinach Chicken Spaghetti is an excellent make-ahead dish. You can assemble the entire dish, cover it tightly with plastic wrap or aluminum foil, and store it in the refrigerator for up to 24 hours before baking. When you’re ready to bake, remove the cover and bake it in a preheated oven at 350°F (175°C) until the cheese is bubbly and golden brown on top, which should take about 25-30 minutes. If baking straight from the fridge, you might need to add a few extra minutes to the baking time to ensure it heats through.

4. Can I freeze baked spinach chicken spaghetti?

Yes, this dish freezes well and is a great option for meal prepping. To freeze, assemble the dish as instructed but do not bake it. Instead, cover it with a layer of plastic wrap followed by aluminum foil, and place it in the freezer. It can be stored in the freezer for up to 3 months. When you’re ready to eat, thaw it in the refrigerator overnight, then bake as directed, adding an extra 10-15 minutes to the baking time to ensure it’s heated all the way through.

5. How can I prevent the pasta from becoming too soft or mushy when baking?

To avoid mushy pasta, it’s important to cook the spaghetti until it’s al dente before baking. Al dente pasta is slightly firm to the bite and will continue to cook slightly in the oven as it absorbs the flavors of the sauce. Additionally, be careful not to overcook the dish in the oven; bake it just until the cheese is melted and bubbly. Overbaking can lead to softer pasta and a drier dish.

6. What can I do if the sauce turns out too thick or too thin?

If the sauce seems too thick when you’re mixing it, you can thin it out by adding a small amount of pasta cooking water or milk. Add it gradually, stirring constantly, until the desired consistency is reached. If the sauce is too thin, you can thicken it by adding a bit more cream cheese or letting it simmer for a few extra minutes on low heat to reduce. Just be careful not to let it simmer too long, as this could cause the sauce to separate or become too thick.

7. Can I add extra vegetables to this dish without altering the flavor too much?

Yes, adding extra vegetables is a great way to boost the nutritional value of this dish without significantly altering the flavor. Vegetables like bell peppers, mushrooms, zucchini, and broccoli work well with the creamy, cheesy sauce. Just be sure to sauté or steam the vegetables before adding them to the dish, so they are fully cooked by the time the dish is baked.
