There are two types of people in this world: those who see corned beef and cabbage as a St. Patrick’s Day obligation, and those who see it as the glorious precursor to the next day’s breakfast. I am firmly in the latter camp. The day after the holiday, my brother and I would race to the fridge, because whoever got there first got the coveted crispy bits from the reheated hash. This is my perfected version, made from scratch, so every single bite is golden and crisp.

Grab These
- 3 tbsp unsalted butter, divided
- 1 large yellow onion, chopped
- 1 lb Yukon Gold potatoes, peeled and diced into ½-inch cubes
- ½ cup beef broth (or water, in a pinch)
- 3 cups cooked corned beef, chopped into small chunks (don’t shred it!)
- 1 cup leftover cooked cabbage and carrots, roughly chopped (optional, but highly recommended)
- Salt and plenty of black pepper
- 4-6 large eggs, for serving
- Fresh parsley, chopped
Let’s Make It
Okay, let’s talk potatoes. You can’t just fry raw potatoes with the onions and expect them to cook through. I learned that the hard way—crunchy, undercooked potatoes are a real mood-killer. So we’re going to parcook them. In a large skillet (cast iron is king for this), melt 2 tablespoons of the butter over medium heat. Add the onion and cook until softened, about 5 minutes.
Add the diced potatoes and pour in the beef broth. Bring it to a simmer, then cover the skillet and let the potatoes steam for about 10-12 minutes. You’re looking for them to be just tender when pierced with a fork. This step is the secret. Once they’re tender, uncover the skillet, crank the heat up to medium-high, and let all that liquid evaporate. You’ll hear the sizzle change—that’s your cue.
Now, add the remaining tablespoon of butter and the chopped corned beef. Spread the whole mixture evenly across the pan and press it down with your spatula. Here is the hardest part: walk away. Don’t touch it for a good 4-5 minutes. Let a proper, brown crust form on the bottom. If you stir it too soon, you’ll just break up the crust. Peek underneath—is it golden? Fantastic. Now, give it a flip, press it down again, and let another crust form. Stir in your leftover cabbage and carrots at the very end, just to warm them through.
While the hash is getting its final crisp on, cook your eggs. I prefer mine fried sunny-side up, so the yolk becomes a rich, golden sauce for the hash. But poached are equally glorious.

Variations & Add-Ins
- From Scratch: No leftovers? No problem! Pick up a 1 lb package of cooked corned beef from the deli counter and sauté some fresh shredded cabbage with the onions.
- Spicy Twist: Add a finely chopped jalapeño to the onions, or a big dash of your favorite hot sauce at the end.
- The Dublin Special: Stir in a tablespoon of whole grain mustard along with the corned beef for a little tangy kick.
Serving Ideas
Scoop a generous portion of that crispy hash onto a plate, top with your perfect fried egg, and sprinkle with fresh parsley. It doesn’t need a single other thing. Though a thick slice of toasted rye bread wouldn’t be turned away.
Storage & Reheating
Store leftovers in an airtight container in the fridge for up to 3 days. Reheating is key: use a skillet over medium heat to bring back the crispiness. The microwave will just make it sad and soft.
My Two Cents
PRESS AND PATIENCE. Pressing the hash down in the pan is what gives you those amazing, craggy, crispy bits. And having the patience to let a real crust form before you stir is what separates a good hash from a life-changing one.
You Asked, I’m Answering
- Can I use canned corned beef? Oh, honey. We can do better than that. The texture is all wrong. If you don’t have leftovers, the pre-cooked stuff from the grocery store is a much better option.
- My hash is sticking! Your pan might not be hot enough when you add the mixture, or it needs a bit more fat. Don’t be shy with the butter.
