This 3-ingredient corned beef hash is the kind of quick, filling supper my own grandma leaned on when the day ran long and the pantry was all you had to work with. It’s pure Midwestern practicality: a can of corned beef, a few potatoes, and an onion, all fried up until the potatoes are tender and the meat gets those irresistible crispy edges that make people wander into the kitchen just from the smell. Dishes like this grew out of farmhouse frugality—stretching shelf-stable staples into something hearty enough to feed a family after chores. It’s not fancy, but it’s the kind of rib-sticking comfort that’s kept its place on our tables for generations.
Serve this hash good and hot, right out of the skillet, on a sturdy plate that can handle a little shine of grease. It’s wonderful with a fried or runny-yolk egg on top if you want to stretch it a bit, and a spoonful of ketchup or a splash of hot sauce is very much in the spirit of old farmhouse tables. A simple side of sliced tomatoes, pickles, or a handful of canned green beans warmed in butter sits nicely next to it. If you’re feeding big appetites, add some toast or biscuits to mop up the crispy, savory bits left on the plate.
3-Ingredient Corned Beef HashServings: 3–4
Ingredients
2 tablespoons vegetable oil or bacon drippings
4 cups peeled and small-diced potatoes (about 3–4 medium russet or yellow potatoes)
1 medium yellow onion, small-diced
1 (12-ounce) can corned beef, chilled and cubed or crumbled
1/2 teaspoon salt, or to taste
1/2 teaspoon black pepper, or to taste
Directions
Have all your ingredients ready before you start: peel and dice the potatoes into small, even cubes; dice the onion; and open the can of corned beef. Chilling the corned beef first helps it hold its shape when you cut or crumble it.
Heat the vegetable oil or bacon drippings in a large, heavy skillet (cast iron if you have it) over medium heat until it shimmers.
Add the diced potatoes to the hot skillet in an even layer. Sprinkle with a pinch of salt and pepper. Let them cook undisturbed for 3–4 minutes so they start to brown on the bottom, then stir and continue cooking, stirring occasionally, until the potatoes are turning golden and just becoming tender, about 8–10 minutes total.
Stir in the diced onion and cook with the potatoes until the onion softens and begins to caramelize around the edges, about 4–5 minutes. If the pan looks dry, add a bit more oil.
Add the corned beef to the skillet, breaking it into bite-sized pieces or crumbles with a spoon or spatula. Stir gently to distribute it evenly with the potatoes and onions.
Press the mixture down into an even layer with the spatula. Turn the heat down slightly to medium-low and let it cook without stirring for 4–6 minutes, or until the bottom develops a deep, crispy brown crust.
Once a good crust has formed, use the spatula to flip the hash in sections, turning it over so new parts can crisp. Press down again and cook another 4–6 minutes, or until you see plenty of browned, crispy bits throughout.
Taste and season with additional salt and black pepper as needed. Serve hot, straight from the skillet, while the edges are still crackly and the potatoes are soft inside.
Variations & Tips
If you want to stay true to the old pantry spirit, you can swap the fresh potatoes for about 3 cups of well-drained canned diced potatoes or leftover boiled potatoes; they’ll brown faster, so keep an eye on them. For a slightly lighter version, use less oil and a nonstick skillet, though you’ll sacrifice a bit of that deep crust Grandma prized. You can also press the hash into individual patties in the pan for neater servings—just give each patty time to form a good crust before flipping. A dash of Worcestershire sauce or a spoonful of prepared mustard stirred in with the corned beef adds a subtle tang that wakes everything up. If you like things spicier, sprinkle in a pinch of crushed red pepper flakes with the onions. Leftover hash reheats nicely in a skillet; just warm it over medium heat with a touch more oil, pressing it down again so you can bring back those crispy edges.
