Ingredients for Corned Beef Hash Recipe

Russet potatoes (4 cups, peeled and 1/2-inch diced): These starchy potatoes create the perfect foundation, holding their shape while developing that gorgeous golden exterior. Their mild flavor lets the corned beef shine. I’ve tried with waxy potatoes like reds before – big mistake! They just don’t break down enough for that perfect hash texture.

Unsalted butter (6 tablespoons, divided): This is where the magic happens – butter creates that rich flavor and essential golden crust. We’ll add it in two stages (I’ll explain why later). If you need a dairy-free version, a good quality vegan butter works, but don’t substitute oil – it just doesn’t create the same rich result.

Sweet onion (1 small, diced): Adds that aromatic sweetness that balances out the savory beef. I love Vidalias, but any sweet or yellow onion works fine. Those natural sugars caramelize during cooking, adding incredible depth.

Kosher salt (1/2 teaspoon): Lifts all the flavors without making anything taste salty. Quick tip: if you’re using canned corned beef, cut back or skip the salt entirely – canned varieties already pack plenty of sodium.

Black pepper (1/2 teaspoon): Provides that classic warming spice that beef loves so much. Fresh ground is best if you have it.

Cooked corned beef (4 cups, chopped): The star of our show! Leftover home-cooked brisket gives the best flavor, but canned works in a pinch (about 2 cans, but remember to adjust your salt).

Garlic powder (1/2 teaspoon): Gives you that savory depth without worrying about burning fresh garlic pieces. The powder spreads evenly throughout every bite.

Onion powder (1/2 teaspoon): Doubles down on that sweet onion flavor, making sure it’s in every mouthful even if some onion pieces get extra caramelized.

How to Make Corned Beef Hash Recipe

1. Get those potatoes ready. Drop your peeled and diced russets into a pot of cold water. Bring it to a boil, then lower to a simmer. Cook for 5-10 minutes until they’re just fork-tender – you want a little resistance when you poke them. Drain thoroughly in a colander and give them a good shake to get rid of extra moisture.
2. Start building flavors. Grab your heaviest skillet (cast iron is my go-to) and heat it over medium. Add 4 tablespoons of the butter and let it melt completely. When it’s nice and hot, add your parboiled potatoes, diced onion, salt, and pepper. You should hear that satisfying sizzle when the potatoes hit the pan – that’s the sound of good things happening!
3. Let the magic begin. Cook this mixture for 8-10 minutes, stirring occasionally – not constantly! You want to give things time to brown. Look for the onions to become translucent with caramelized edges and potatoes developing golden patches. Your kitchen should smell amazing by now.
4. Bring in the beef. Add your chopped corned beef along with the garlic powder and onion powder. Stir everything together gently – you don’t want to mash up those potatoes. Make sure those seasonings get distributed evenly throughout.
5. Create that first beautiful crust. Here’s where my grandmother’s technique comes in – take the back of your spatula and firmly press everything into an even layer across the bottom of the skillet. Now, hands off! Let it cook undisturbed for 3-5 minutes until a golden crust forms. I know it’s tempting to peek, but trust the process!
6. Flip and add more butter. Once it’s nicely browned, use your spatula to scrape and flip sections of the hash, bringing those crispy bits to the top. Don’t worry – it won’t flip in one piece like a pancake! This is supposed to happen. Now add those remaining 2 tablespoons of butter around the edges, letting it melt into everything.
7. Build another crust layer. Press everything down again into an even layer and let it cook undisturbed for another 3-5 minutes. That second addition of butter keeps things from drying out and helps build those layers of flavor we’re after.
8. One more time for good luck. Do one more round of flipping and pressing, letting each pressed surface get that beautiful golden-brown color before disturbing it. This third round completes the layering of textures that makes hash so special.
9. Finish with a flourish. Once you’ve got the crispiness level you love (usually after three rounds of pressing and flipping), take it off the heat. If you want, sprinkle on some chopped fresh parsley for color and serve right away while that contrast between crispy exterior and tender interior is at its peak.

Texture and Final Result

When you nail this recipe, your hash will look like a beautiful mosaic – a patchwork of golden-brown, caramelized bits contrasting with the reddish-pink corned beef and lighter potato interior.

Take a bite and you’ll get that satisfying crunch that gives way to tender, flavorful morsels inside. The slight sweetness from those caramelized onions plays against the savory depth of the beef, all wrapped up in that buttery richness. It should hold together just enough to form perfect bites without turning into a compact mass.

Expert Tips for Success

• Don’t skip the two-stage butter method: That first amount creates your flavor base, while the second keeps everything from drying out during extended cooking and helps develop those amazing crispy layers.
• Nail the potato doneness: Parboil just until fork-tender – if they’re undercooked, you’ll get hard bits in the final dish; if overcooked, they’ll fall apart during frying and turn to mush.
• The press is crucial: Use firm, even pressure with your spatula when forming each crust layer. This isn’t just fried potatoes with meat – it’s that compression that creates the distinctive hash texture we’re after.
• Patience pays off: Those undisturbed cooking periods (3-5 minutes each) are when the magic happens. If you tend to get antsy, set a timer on your phone!
• Taste before adding salt: Especially if using canned corned beef – those cans often pack enough sodium already.

Storage & Make-Ahead

Fridge storage: Once cooled, pop leftovers in an airtight container and refrigerate for up to 3 days. The flavors actually get even better overnight, though you’ll lose some of that crispiness.

Freezer option: While not ideal, you can freeze hash for up to 3 months in freezer-safe containers. Thaw overnight in the fridge before reheating.

Bringing back the crunch: To restore some crispiness, reheat leftovers in a hot skillet with a tablespoon of butter, pressing down to form a new crust. In a rush? The microwave works but you’ll sacrifice that textural contrast.

Get ahead: You can parboil those potatoes up to 2 days ahead and keep them in the fridge, which cuts your day-of prep time way down.

Variations & Customizations

Load up on veggies: Toss in diced bell peppers or grated carrots with the onions for color, nutrition, and flavor. They caramelize beautifully alongside everything else.

Spice it up: Add 1/4 teaspoon cayenne or red pepper flakes when adding the seasonings. Finish with chopped cilantro and a squeeze of lime for a Mexican-inspired twist that’ll wake up your taste buds.

Make it a complete breakfast: Create little wells in your finished hash and crack eggs directly into them. Cover and cook until the eggs reach your preferred doneness for a one-pan breakfast that’ll fuel your whole morning.

No corned beef? No problem! Try leftover roast beef, smoked ham, or even browned ground beef seasoned with a pinch of cloves and allspice to mimic that distinctive corned beef flavor.

Serving Suggestions

This hash is pretty fantastic on its own, but here’s how I love to serve it:

For breakfast: Top with a fried or poached egg where that runny yolk creates a natural sauce that makes everything even richer. Add some buttered toast on the side to soak up any extras.

For dinner: Pair it with a simple green salad dressed with vinaigrette – that bright acidity cuts through the richness perfectly. A dollop of sour cream or creamy horseradish sauce adds a tangy kick.

For brunch with friends: Set up a little hash bar with toppings – chopped green onions, hot sauce, diced avocado, crumbled bacon, and grated cheese – so everyone can customize their own plate.

The History Behind Corned Beef Hash

There’s something humbling about comfort foods born from necessity. Corned beef hash started as a clever way to stretch leftovers during tough times. While it has European roots in various chopped meat dishes, it really took off in America during World War II when meat rationing made fresh cuts scarce. Canned corned beef became widely available, and home cooks got creative, mixing it with potatoes to make satisfying, filling meals.

The word “hash” comes from “hacher,” French for “to chop,” which perfectly describes the dish’s chopped-and-mixed nature. What began as a thrifty solution has evolved into a beloved comfort food that’s earned its place on diner menus across the country, especially around St. Patrick’s Day when corned beef is abundant.

FAQs about Corned Beef Hash Recipe

How do you make a good corned beef hash?

The secret lies in three key moves. First, parboil those potatoes until just tender but not mushy. Second, add butter in stages – this keeps everything moist and helps build multiple layers of crispy goodness. Third, master the pressing technique – firmly press everything into an even layer and let it cook undisturbed until golden before flipping. This creates that amazing contrast between crispy outside and tender inside that makes hash so crave-worthy. Oh, and good quality corned beef cut into small, even pieces helps everything cook uniformly.

What can you mix with corned beef hash?

The possibilities are nearly endless! Colorful bell peppers add sweetness, while jalapeños or green chilies bring heat. Fresh herbs like thyme or rosemary add wonderful aromatics. A dash of Worcestershire sauce or splash of beef broth deepens those savory notes. For toppings, try a runny egg, hot sauce, sour cream, fresh herbs, or avocado slices. Some mornings I add shredded cheese during the final minutes of cooking – it melts into everything and binds it together beautifully.

What is the secret to the best corned beef?

Whether you’re making it from scratch or buying it prepared, a few factors make all the difference. For homemade versions, proper brining with the right spice blend (coriander, mustard seeds, bay leaves, and pink curing salt) creates that signature flavor. But regardless of preparation, cooking technique matters most – low and slow braising is key. Cook until it’s fork-tender but not falling apart, which typically takes 50-60 minutes per pound at a gentle simmer. Always slice against the grain when serving it whole, and let it rest before cutting so all those juices stay where they belong.

What is corned beef hash in a can made of?

Canned hash typically contains beef that’s been salt-cured (that’s the “corned” part), mixed with pre-cooked diced potatoes, onions, and seasonings. Most commercial versions include additives like salt, sugar, spices, and preservatives for shelf stability. The meat-to-potato ratio varies by brand – budget versions tend to go heavier on the potatoes. While convenient, canned hash generally has a softer, more uniform texture than homemade and significantly more sodium. Brands like Hormel and Libby’s are the big names, with quality and ingredients varying between their premium and economy options.
