Why You’ll Love This Recipe

This dish is the definition of hands-off comfort food. With just three main ingredients, it is budget-friendly, forgiving, and perfect for days when you want something warm without a lot of work.

The flavors are rich and familiar. Canned corned beef brings a deep, savory saltiness, while the potatoes soak up all that goodness and turn tender and comforting.

It is also wonderfully adaptable. You can add onions, garlic, cheese, or a splash of broth, or serve it as a hash with crispy edges.

Ingredients

2 pounds Yukon Gold or red potatoes, cut into 1-inch cubes
1 can (12 ounces) corned beef, broken into chunks
1/2 cup unsalted butter, cut into pieces

Salt, black pepper, and a splash of water or broth are considered free pantry staples and can be added as needed.

Directions

Lightly grease the inside of a 4- to 6-quart slow cooker.
Place the cubed potatoes in the bottom of the slow cooker. Season with salt and pepper.
Scatter the butter pieces over the potatoes.
Cover and cook on LOW for 5 to 6 hours, or on HIGH for 2 1/2 to 3 hours, until the potatoes are fork-tender.
Add the corned beef chunks and stir gently. If the mixture looks dry, add a splash of water or broth.
Cover and cook on LOW for another 30 to 45 minutes, until the corned beef is heated through and the flavors meld.
Stir gently, taste, and adjust seasoning. Serve hot.

Variations

Corned Beef Hash Style: After cooking, transfer to a skillet and fry in a little butter until crispy.
Onion Lover’s Version: Add 1 sliced yellow onion with the potatoes.
Cheesy Poor Man’s Dinner: Stir in 1 1/2 cups shredded cheddar during the last 15 minutes.
Spicy Kick: Add red pepper flakes, diced jalapeños, or a dash of hot sauce.
Cabbage Addition: Add 3 cups chopped cabbage during the last hour for a complete one-pot meal.
Breakfast Version: Top each serving with a fried or poached egg.

Expert Tips

Cut the potatoes into even cubes so they cook at the same rate.
Do not add the corned beef too early. It is already cooked and can break down too much.
Use butter, not margarine, for the best flavor and richness.
Do not lift the lid often. Trapped steam helps the potatoes become tender.
Let the dish rest for a few minutes before serving so the flavors settle.

Storage and Reheating

Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat gently in the microwave or in a skillet over medium heat with a splash of water or broth. For crispy edges, reheat in a skillet with a little butter. This dish does not freeze well because the potatoes can become watery and grainy upon thawing.

Frequently Asked Questions

Can I use a different potato? Yes. Yukon Gold and red potatoes hold their shape best, but russets work too.
Can I use dried beef instead of canned corned beef? Yes, but reduce the salt since dried beef is very salty.
Why did my potatoes turn mushy? They may have cooked too long. Check them at the lower end of the cook time.
Can I add broth? Yes. A splash of beef broth adds extra flavor and keeps the dish moist.
Can I double this recipe? Yes. Use a 6- to 8-quart slow cooker and extend the cook time slightly.
