The ultimate crispy diner-style breakfast, made better at home. Golden, crusty potatoes and savory corned beef fried until the edges are deeply browned, topped with sunny eggs whose runny yolks soak into every bite. It’s the best use for leftover corned beef — hello, post-St. Patrick’s Day — and pure weekend comfort. The secret to crispy hash is patience: let it sit and brown.
Fun fact: “hash” comes from the French “hacher,” meaning to chop. Corned beef hash became an American diner staple during and after World War II, when canned corned beef was plentiful and cheap — and it’s been a beloved way to use leftovers ever since.
Why this recipe works
PAR-COOK the potatoes. A quick boil or microwave means the potatoes get crispy outside without staying raw inside.
DON’T stir too much. Press the hash flat and let it sit so a deep golden crust forms before flipping.
RUNNY eggs. A soft yolk is the sauce — fry or poach so it spills over the crispy hash.
Ingredients
Serves 4.
Hash:
1.5 lbs (680 g) potatoes, diced small
2 tbsp butter + 1 tbsp oil
1 onion, diced
2 cups cooked corned beef, chopped (about 12 oz)
1/2 tsp smoked paprika
Salt and pepper
1 tbsp chopped parsley
To serve:
4 eggs
Hot sauce
Extra parsley and cracked pepper
Instructions
Step 1: Par-cook potatoes
Boil the diced potatoes 5-6 minutes until just barely tender, then drain well and let them steam-dry.
Step 2: Start the hash
Heat butter and oil in a large (preferably cast iron) skillet over medium-high. Add the potatoes in an even layer.
Step 3: Crisp
Cook 5-6 minutes without stirring to build a crust, then flip and brown the other side.
Step 4: Add beef and onion
Stir in the onion, corned beef, smoked paprika, salt and pepper. Press flat and cook 5-7 minutes, flipping occasionally, until deeply crispy.
Step 5: Cook the eggs
Make 4 wells in the hash (or fry the eggs separately). Crack in the eggs, cover, and cook 3-4 minutes until whites set but yolks stay runny.
Step 6: Serve
Scatter with parsley, crack on pepper, and serve hot with hot sauce.

Pro tips for the best corned beef hash with egg
Cast iron wins. It holds heat and gives the crispiest crust; a heavy nonstick is the runner-up.
Use leftover potatoes. Cold cooked potatoes from the fridge crisp up beautifully — skip the par-cook.
Patience = crust. The biggest mistake is over-stirring. Let it sit to brown between flips.
No leftover corned beef? Deli corned beef, chopped, works great as a shortcut.
Frequently asked questions
Can I use canned corned beef?
Yes — it’s traditional and crisps up well. Break it into chunks and fry until browned.
What potatoes are best?
Yukon gold or russet. Yukon holds shape and crisps; russet gets fluffy inside and crunchy outside.
How do I get it really crispy?
Dry the potatoes well, use a hot pan with enough fat, and resist stirring so a crust can form.
Can I make it ahead?
The hash reheats well in a hot skillet; cook the eggs fresh. Store the hash up to 4 days in the fridge.
Is it just for breakfast?
Not at all — corned beef hash with a fried egg makes a great quick dinner too.
