Corned Beef Hash with Fried Eggs
By Margaret Flynn
Rate this recipe
Corned beef hash is thrift turned into a beloved breakfast, a dish built to give yesterday's boiled dinner a glorious second act. The word "hash" comes from the French hacher, to chop, and that is exactly the idea: leftover corned beef and potatoes diced fine, pressed into a hot pan, and fried until a deep, crispy crust forms. The dish took deep root in American diners and the British and Irish kitchens that brought corned beef across the Atlantic, becoming a Saint Patrick's Day morning-after tradition and a weekend brunch staple year-round. What makes it sing is the crust. Parboiling the potatoes first ensures they cook through, and then the real magic happens when you press the hash down and leave it alone, resisting the urge to stir, so the starch caramelizes against the cast iron into golden, craggy edges. The salty, peppery corned beef crisps in spots alongside it. Crowning the whole skillet with fried eggs, their runny yolks ready to spill into every crevice, turns a frugal hash into something genuinely indulgent. A shower of fresh parsley cuts the richness. Served straight from the pan, it is hearty, soul-warming food that tastes far more than the sum of its humble parts.
Ingredients
Serves 4Instructions
- 1
Parboil the diced potatoes in salted boiling water for 3-4 minutes until slightly tender but not mushy. Drain well.
- 2
Heat the olive oil in a large cast-iron skillet over medium-high heat. Add the onion and cook for 3 minutes until softened.
- 3
Add the parboiled potatoes to the skillet. Press them down with a spatula and cook undisturbed for 4-5 minutes to develop a crust. Stir and repeat until potatoes are golden brown and crispy.
- 4
Stir in the diced corned beef and black pepper. Cook for another 5 minutes, stirring occasionally, until the meat is heated through and crispy in spots.
- 5
Make 4 wells in the hash mixture. Crack an egg into each well. Cover the skillet and cook for 3-5 minutes, or until the egg whites are set but yolks are still runny.
- 6
Remove from heat, sprinkle with fresh parsley, and serve hot directly from the skillet.
Chef's Tips
- ✦ Parboil the diced potatoes just 3 to 4 minutes until barely tender, then drain them very well; surface moisture is the enemy of a crispy crust.
- ✦ Use a cast-iron skillet and let it get properly hot before adding the potatoes so they sear rather than steam.
- ✦ Press the hash down with a spatula and let it cook undisturbed for several minutes at a time; constant stirring prevents the golden crust from ever forming.
- ✦ Make deep wells in the hash before cracking in the eggs so the whites settle and cook evenly without running across the surface.
- ✦ Cover the skillet while the eggs cook to gently set the whites from the top while keeping the yolks runny, then uncover and serve immediately.
Ingredient Substitutions
-
cooked corned beef → leftover roast beef, pastrami, or canned corned beef
Any cooked, salty beef works; canned corned beef is the classic shortcut when you have no leftovers.
-
potatoes → sweet potatoes or frozen diced hash browns
Sweet potatoes add color and sweetness, while pre-diced frozen potatoes skip the peeling and parboiling step.
-
onion → shallots or the white parts of scallions
Use these for a milder, slightly sweeter aromatic base in the hash.
-
olive oil or butter → bacon fat or ghee
Bacon fat adds smoky depth and helps the potatoes crisp; ghee keeps the dish dairy-free.
-
fresh parsley → fresh chives or green onion tops
Either delivers the same fresh, green finish that brightens the rich hash.

Frequently Asked Questions
What's the safe internal temperature for the fried eggs? ▼
For fully cooked, safe eggs, cook until both the white and yolk are firm, which corresponds to an internal temperature of 160°F (71°C). For the classic runny-yolk hash, the whites should be fully set while the yolk stays soft; those at higher risk should opt for firm yolks or pasteurized eggs.
Can I make corned beef hash ahead of time? ▼
Yes. Cook the potato-and-corned-beef hash through, cool it, and refrigerate in an airtight container for up to 3 days. Reheat it in a hot skillet to re-crisp the crust, then make fresh wells and cook the eggs just before serving for the best texture.
How do I store and reheat leftover hash? ▼
Store leftover hash without the eggs in an airtight container in the refrigerator for up to 3 days. Reheat in a hot, lightly oiled skillet over medium-high heat until crisped and steaming throughout; the microwave works in a pinch but won't restore the crust.
Why isn't my hash getting crispy? ▼
Soggy hash usually means the potatoes had too much moisture or the pan was too crowded or not hot enough. Drain parboiled potatoes thoroughly, use a hot cast-iron skillet, spread the hash in an even layer, and let it sit undisturbed so a crust can form before stirring.
Can I make this recipe without leftover corned beef? ▼
Yes. Canned corned beef works well and is the traditional shortcut; just crumble it in and let it crisp. You can also substitute leftover roast beef or pastrami. If starting from raw corned beef brisket, you must boil or braise it until tender before dicing it for the hash.
How do I scale this for more servings? ▼
This recipe serves 4 and scales easily, but work in batches or use a second skillet rather than overcrowding one pan, which steams the potatoes instead of crisping them. Add one egg per serving and make a corresponding number of wells in the hash.
