Silas has a theory that the day after St. Patrick’s Day is secretly better than the holiday itself.
I used to think he was just being dramatic (he does that). But then I actually made hash with our leftover corned beef and, well, now I kind of get it.
This dish takes everything a little crispy, a little salty, and turns it into breakfast royalty. Potatoes get golden and crackly on the edges. The corned beef gets these little charred bits that taste like they were made on purpose. And a fried egg on top just seals the deal.
You don’t even need leftovers to make this happen. Grab a can of corned beef or cook a small piece from scratch, and you’re in business any day of the week.
Let’s get into it.
What You’ll Need
| Ingredient | Amount |
|---|---|
| Corned beef (cooked, diced) | 2 cups |
| Russet potatoes | 1.5 lbs (about 3 medium) |
| Yellow onion | 1 medium, diced |
| Green bell pepper | 1, diced |
| Garlic cloves | 2, minced |
| Butter | 2 tbsp |
| Olive oil | 2 tbsp |
| Smoked paprika | 1/2 tsp |
| Black pepper | 1/2 tsp |
| Salt | to taste |
| Fresh parsley, chopped | 2 tbsp |
| Eggs (optional, for topping) | 4 |
A quick note on the corned beef. Leftover brisket works beautifully here, but so does canned corned beef if that’s what you’ve got on hand. Both get you to the same delicious place.
Tools You’ll Need
- Large cast iron skillet (or a heavy nonstick pan)
- Cutting board and sharp knife
- Spatula
- Small saucepan (if par-boiling potatoes)
Pro Tips
1. Par-boil your potatoes first. I skipped this step the first time I made hash and ended up with potatoes that were burnt outside and raw inside. Boil diced potatoes for about 5 minutes before they hit the skillet. Total game changer.
2. Don’t crowd the pan. Hash needs room to breathe or it just steams instead of crisping up. Use a big skillet, and if you’re doubling the recipe, cook it in batches.
3. Resist the urge to stir constantly. Let the potatoes sit undisturbed for a few minutes at a time so they actually develop that golden crust. Flip, don’t toss.
4. Cast iron is worth it here. It holds heat evenly and gives you the best crispy bottom. If you don’t own one yet, this is the recipe that’ll convince you to grab one.
5. Season in layers. A little salt on the potatoes while they boil, a little more when they hit the pan, and a final taste test before serving. Layered seasoning makes a much more flavorful hash than dumping it all in at once.
Instructions
- Prep the potatoes. Dice the russet potatoes into small, even cubes (about 1/2 inch). Boil in salted water for 5 minutes, then drain well and pat dry.
- Heat the pan. Add the butter and olive oil to your skillet over medium-high heat until the butter is melted and slightly foamy.
- Cook the potatoes. Add the potatoes in a single layer. Let them sit for 3 to 4 minutes without stirring, then flip and repeat until golden brown on most sides, about 10 minutes total.
- Add the vegetables. Toss in the onion and bell pepper. Cook for another 5 minutes, stirring occasionally, until softened.
- Add the garlic and corned beef. Stir in the minced garlic and diced corned beef. Cook for 5 to 7 minutes, letting the beef get slightly crispy on the edges.
- Season. Sprinkle in the smoked paprika, black pepper, and salt to taste. Give everything a good stir.
- Fry your eggs (optional but recommended). In a separate pan, fry the eggs to your liking while the hash finishes crisping up.
- Serve. Plate the hash, top with a fried egg, and sprinkle with fresh parsley.
Substitutions and Variations
| Original | Substitute | Notes |
|---|---|---|
| Russet potatoes | Sweet potatoes | Adds a slightly sweet contrast |
| Corned beef | Pastrami or roast beef | Great way to use other deli leftovers |
| Green bell pepper | Red or yellow bell pepper | Sweeter flavor |
| Butter | Ghee | Good for those avoiding dairy solids |
| Fried egg topping | Poached or scrambled egg | Whatever you’re in the mood for |
Make Ahead Tips
You can par-boil and dice the potatoes up to 2 days ahead. Just store them in the fridge in an airtight container.
The onion, pepper, and corned beef can also be diced ahead of time. This turns hash into a genuinely fast weeknight or weekend breakfast option since most of the prep work is already done.

Diet-Friendly Swaps
- Lower sodium: Rinse the diced corned beef under cold water before cooking to cut down on saltiness.
- Lower carb: Swap half the potatoes for diced radishes or turnips.
- Dairy-free: Use olive oil instead of butter throughout.
Meal Pairing Ideas
Corned beef hash pairs really well with something acidic to cut through the richness. A simple side salad with vinaigrette works, or even a small bowl of pickled vegetables.
For breakfast, toast with a bit of jam rounds things out nicely.
Leftovers and Storage
Store leftover hash in an airtight container in the fridge for up to 4 days.
Reheat in a skillet over medium heat to bring back some of that crispiness. The microwave works in a pinch, but you’ll lose the crunch factor.
This dish also freezes surprisingly well. Portion it into freezer bags and it’ll keep for up to 2 months. Thaw overnight in the fridge before reheating in a pan.
FAQ
Can I use raw corned beef instead of cooked?
Yes, but you’ll need to cook it separately first, either by boiling or braising until tender, then dice it up before adding it to the hash.
Why is my hash soggy instead of crispy?
This usually happens from overcrowding the pan or not letting the potatoes sit long enough before flipping. Give them space and patience.
Can I make this in an air fryer?
You can crisp up the potatoes in an air fryer separately, then combine everything in a skillet to finish. It’s an extra step, but it does help with texture if your stovetop tends to run cool.
Is corned beef hash healthy?
It’s a hearty dish with a good amount of protein, though it does run higher in sodium. Balancing it with a side salad or lighter meal later in the day helps even things out.
