Ingredients You’ll Need

For the Base

Leftover roast beef (1½ cups/350g): This is where the magic starts! Just chop it into bite-sized pieces – and don’t worry if they’re not all perfectly uniform.

Mushrooms (14 oz/400g): I love using chestnut (crimini) mushrooms for their deeper flavor, but honestly, regular button mushrooms from the grocery store work perfectly too.

Onions (2, thinly sliced): These will practically melt into the sauce as they cook down. Pure flavor foundations!

Garlic (2 cloves, minced): Optional, but who are we kidding? Garlic makes everything better.

Beef broth (1⅓ cups/300ml): This is the backbone of our sauce flavor. If you have homemade, amazing! If not, a good quality store-bought works great too.

Rigatoni pasta (14 oz/400g): Those tubes with ridges are perfect here – they grab onto the sauce in the most delicious way.

For the Signature Sauce

Quark cheese (1 cup/240g): This is my little secret for creamy-yet-lighter sauce. If you can’t find it, don’t panic – Greek yogurt works in a pinch!

Sour cream (½ cup/120g): This brings that classic stroganoff tang we all love. The reduced-fat version works beautifully here.

Dijon mustard (1 tbsp): Just a spoonful adds a subtle kick that really makes the other flavors pop.

Worcestershire sauce (1 tbsp): That dark, savory magic that ties everything together. Don’t skip this!

Cornstarch slurry (1 tbsp in 2 tbsp cold water): This gives us that perfect sauce thickness that clings lovingly to every ridge of pasta.

For the Perfect Finish

Grated Parmesan (3 tbsp): This creates that gorgeous golden crust that everyone will fight over.

Reserved pasta water (¼ cup/60ml): The unsung hero of pasta dishes everywhere – it’s the secret to adjusting your sauce to silky perfection.

Flat leaf parsley (handful, chopped): Adds a pop of color and fresh flavor that balances all that richness.

Low-calorie cooking spray: Lets us sauté everything properly without going overboard on calories.

Freshly ground black pepper: That final flourish that adds both flavor and visual appeal.

How to Make Beef Stroganoff Pasta Bake

Prep Work (10 minutes)

1. Get a large pot of water boiling for your pasta. Don’t forget to salt it – it should taste like the sea!
2. While that’s heating up, slice your mushrooms, thinly slice those onions, and mince your garlic if using.
3. Cut your leftover roast beef into bite-sized pieces. If there’s a bit of fat, don’t stress about trimming every last bit – that’s flavor!
4. Mix 1 tablespoon cornstarch with 2 tablespoons cold water in a small bowl until smooth.
5. Measure everything else out so it’s ready to grab when you need it. Trust me, this makes cooking so much more enjoyable.

Create the Stroganoff Base (15 minutes)

1. Cook the pasta: Toss your rigatoni into that boiling water and cook until it’s just shy of al dente – about 2 minutes less than the package says. Before you drain it, scoop out ¼ cup of that starchy pasta water (it’s liquid gold, I tell you!).
2. Build the flavor foundation: Heat up a large, deep skillet over medium heat. Give it a good spray with that low-calorie cooking spray. Add your onions and let them cook for 3-4 minutes until they start to soften and become translucent.
3. Add the mushrooms: Crank the heat up a bit and add those mushrooms (and garlic if you’re using it). Cook for 5-7 minutes, stirring occasionally. You’ll know they’re ready when they’ve released their moisture and started to turn golden. Your kitchen should smell amazing right about now!
4. Create the sauce base: Pour in that beef broth and Worcestershire sauce, making sure to scrape up all those flavorful bits stuck to the bottom of the pan. Let it gently simmer and reduce for 2-3 minutes.
5. Thicken the sauce: Stir in the Dijon mustard (don’t worry, it won’t taste mustardy), then pour in your cornstarch slurry while stirring constantly. You’ll see it thicken before your eyes – so satisfying!
6. Make it creamy: Turn the heat down to low. This is important! Add your quark and sour cream, stirring gently until everything comes together into a silky smooth sauce. No white streaks should remain.
7. Add the beef: Gently stir in your leftover roast beef pieces. Pro tip: if you have any leftover gravy, throw a spoonful or two in here – it’s absolutely divine! Season with salt and freshly ground black pepper to taste.

Combine and Bake (5 minutes)

1. Combine with pasta: Add your drained rigatoni directly to the sauce, folding everything together until each piece is gloriously coated. If it looks a bit thick, splash in some of that reserved pasta water. You want it silky, not gloopy.
2. Prepare for broiling: If your skillet can go in the oven, great! If not, transfer everything to a baking dish. Don’t press it down too much – some texture on top is good!
3. Add the finishing touch: Sprinkle that Parmesan cheese evenly across the top, followed by a good grinding of black pepper.
4. Broil to golden perfection: Place under a medium-high broiler for about 5 minutes. Keep an eye on it! You want a beautiful golden crust with some slightly darker spots. There’s a fine line between “gorgeously caramelized” and “oops, it’s burnt.”
5. Rest briefly: Let it sit for 2-3 minutes before serving. I know it’s hard to wait, but this lets the sauce settle and the flavors meld together.
6. Garnish: Sprinkle with fresh chopped parsley just before bringing it to the table. That pop of green really makes the dish look special.

Expert Tips for Stroganoff Pasta Bake Success

• Watch that pasta like a hawk: Seriously, start tasting it a minute or two before the package says it’s done. It’ll keep cooking in the hot sauce, so you want it with a bit of bite still.
• Sauce consistency is key: Before adding the pasta, the sauce should coat the back of a spoon. Too runny? Let it simmer a bit longer. Too thick? That’s what the pasta water is for!
• Mushroom magic: Want to take the flavor up a notch? Add 1-2 teaspoons of porcini mushroom powder to your beef broth. It’s like a flavor bomb of pure umami.
• Short on time? Skip the broiling step and serve straight from the stovetop. It’ll still be delicious, just without the crispy top.
• Leftover gravy is liquid gold: If you’ve got gravy left from your roast, stir in 2-3 tablespoons. It adds incredible depth that takes this dish to restaurant-level yumminess.
• Make it when it suits you: You can prep everything up to the broiling stage earlier in the day, then just pop it under the broiler right before dinner. Perfect for those days when you know the evening will be hectic.

Storage & Make-Ahead Information

Fridge storage: Pop any leftovers in an airtight container and they’ll keep beautifully for 2-3 days. Between you and me, I think it tastes even better the next day after the flavors have had time to get friendly with each other.

Reheating the right way: For best results, reheat gently in the microwave at 70% power, giving it a stir halfway through. Or warm it in a covered dish in a 325°F (165°C) oven until it’s heated through. Just don’t blast it on high heat or you might end up with split sauce.

Freezer thoughts: I’ll be honest – this isn’t the best dish for freezing. The cream-based sauce can get a bit weird when thawed, and the pasta texture suffers. Some dishes are just meant to be enjoyed fresh!

Prepping ahead: You can absolutely make the entire dish up to the broiling stage, cover it tightly, and refrigerate for up to 24 hours. Just let it sit at room temperature for about 30 minutes before broiling so it heats evenly.

Variations and Substitutions

Mix up your protein:

• Got leftover roast chicken or turkey instead? Swap it in (and use chicken broth instead of beef).
• Working with a tighter budget? Brown 1lb (450g) of ground beef instead of using leftover roast.
• Leftover pork roast works beautifully too – it gives a slightly different but equally delicious flavor profile.

Dietary tweaks:

• Need dairy-free? Use dairy-free cream cheese and a non-dairy sour cream alternative.
• Gluten concerns? Grab your favorite gluten-free pasta and double-check your Worcestershire sauce is gluten-free.
• Vegetarian version: Simply double the mushrooms (28oz/800g) and use vegetable stock – it’s still hearty and satisfying without meat.

Flavor adventures:

• Stir in 1 tablespoon of paprika for a Hungarian-inspired twist.
• A splash (2 tablespoons) of brandy or white wine added with the stock brings an elegant touch.
• Fresh thyme leaves (about 2 teaspoons) stirred in with the parsley adds a wonderful herbal note.

Perfect Pairing Suggestions

This comforting pasta bake pairs beautifully with:

• A simple green salad with a bright, tangy dressing to cut through the richness
• Some steamed green beans or broccoli with a squeeze of lemon
• A glass of mellow red wine like Merlot or Pinot Noir (or just your favorite Tuesday night beverage!)
• Crusty garlic bread for when you need serious comfort food (and for scooping up any sauce left on your plate)
• Roasted cherry tomatoes that burst with sweet acidity against the creamy sauce

Frequently Asked Questions About Beef Stroganoff Pasta Bake

What pasta goes with beef stroganoff?

Rigatoni is my go-to for this dish – those tubes with ridges just grab onto the sauce perfectly. But honestly, any substantial pasta shape works great! Penne, fusilli, or farfalle (bow ties) are all excellent choices. I’d stay away from delicate pastas like angel hair or spaghetti though – they just can’t stand up to the hearty sauce and that trip under the broiler. Whatever shape you choose, remember my golden rule: cook it 1-2 minutes less than the package says for the perfect texture in the finished dish.

Can you cook beef stroganoff in the oven?

You bet! While traditional stroganoff is strictly stovetop business, this pasta bake version gets so much from that quick finish under the broiler. That heat creates that incredible golden Parmesan crust while helping the creamy sauce bubble and settle into the pasta. It’s also super convenient – you can make everything ahead and just do the broiler part right before dinner. Talk about stress-free entertaining!

What is the sauce in beef stroganoff made of?

Classic beef stroganoff sauce is built around sour cream, beef stock, and usually some mustard and Worcestershire sauce for depth. In this lighter version, I use quark cheese (it’s like a high-protein, low-fat fresh cheese) mixed with some reduced-fat sour cream to get that signature tang without all the calories. Instead of using heavy cream or a flour roux for thickening, a simple cornstarch slurry does the trick, keeping it lighter while still giving you that luxurious, silky mouthfeel we all crave in a stroganoff.

What cut of meat is best for beef stroganoff?

This recipe is perfect for using up leftover roast beef, which is what makes it so practical! But if you’re making it from scratch, traditional stroganoff typically uses quick-cooking tender cuts like sirloin or ribeye. If you’re going the fresh route, look for beef tenderloin or sirloin steak and cut it into thin strips. Using ground beef? Go for a lean mix (90/10) for good flavor without swimming in fat. What I love about this pasta bake is how forgiving it is – even tougher cuts work beautifully because they’ve already been tenderized during the initial roasting.

Can I make this recipe ahead of time?

Absolutely! This dish was practically made for busy people. You can prepare everything up to the broiling stage, cover it, and refrigerate for up to 24 hours. When you’re ready to eat, just let it sit at room temperature for about 30 minutes, then broil until it’s golden and bubbling. I actually think the flavors get even better with a little time to mingle together, making this perfect for when you have friends coming over and don’t want to be stuck in the kitchen.

Why is my sauce splitting or curdling?

Heat is usually the culprit here. The key is to make sure you turn down the heat to low before adding any dairy components, and never let the sauce boil after adding the quark and sour cream. When reheating leftovers, gentle heat is your friend – use 70% power in the microwave or a low oven temperature. If your sauce does start to separate, sometimes a quick whisking and adding a splash of warm broth can help bring everything back together. Don’t panic – even if it splits a bit, it will still taste delicious!
