This hearty Corned Beef Hash transforms leftover corned beef into a delicious meal that's perfect any time of day. The combination of crispy-edged potatoes, savory corned beef, and caramelized onions creates a satisfying dish that's been beloved for generations.
I first made this recipe after St. Patrick's Day when I had leftover corned beef and needed a creative way to use it up. My family was so impressed that it's now requested regularly even when we don't have leftovers.
Ingredients
- Russet potatoes: Provide the perfect starchy base that crisps beautifully while staying tender inside
- Unsalted butter: Creates a rich flavor foundation and helps achieve those crispy golden edges
- Sweet onion: Adds natural sweetness that balances the salty corned beef
- Cooked corned beef: Brings that distinctive savory flavor and hearty texture
- Garlic powder and onion powder: Enhance the overall flavor without overwhelming the dish
- Kosher salt and black pepper: Essential for proper seasoning
How To Make Corned Beef Hash
- Prepare the potatoes:
- Boil the diced russet potatoes until just fork tender which should take between 5 to 10 minutes. This partial cooking ensures they'll finish perfectly in the skillet without becoming mushy. Be sure to drain them thoroughly as excess moisture will prevent proper browning.
- Create the flavor base:
- Melt 4 tablespoons of butter in a large skillet over medium heat. Add the parboiled potatoes along with diced sweet onion and season with salt and pepper. Cook this mixture for 8 to 10 minutes stirring occasionally to promote even browning. The onions should become translucent and both components should begin to develop golden edges.
- Incorporate the corned beef:
- Add the chopped corned beef to the skillet along with garlic powder and onion powder. Stir everything together until well combined ensuring the seasonings are evenly distributed throughout the mixture. The meat will begin to warm through and release its savory flavors.
- Develop the first crust:
- Use the back of your spatula to press the entire mixture down into an even layer covering the bottom of the skillet. Let it cook undisturbed for 3 to 5 minutes which allows a golden crust to form on the bottom creating that signature texture contrast.
- Create multiple layers of crispiness:
- Scrape and flip the hash so the crusty portion faces upward. Add the remaining 2 tablespoons of butter and incorporate it throughout. Press everything down again into an even layer and allow another crust to form. Repeat this process at least two more times until you achieve your desired level of browning and crispiness.

The butter is truly the secret ingredient in this recipe. I discovered through much experimentation that dividing the butter between the initial cooking and the later stages creates multiple opportunities for developing those irresistible crispy edges that everyone fights over at the table.
Storage Tips
Store leftovers in an airtight container in the refrigerator for up to 3 days. The flavors actually improve overnight as they meld together. To reheat properly use a skillet rather than a microwave to maintain some crispiness. Add a small amount of butter to the pan before reheating to restore that fresh made texture.
Make Ahead Options
You can prepare components in advance to streamline the cooking process. Dice and parboil the potatoes up to two days before storing them in the refrigerator. Chop the corned beef and onions ahead of time as well. When ready to cook simply proceed with the recipe as written starting with melting the butter in the skillet.
Serving Suggestions
This versatile hash pairs beautifully with sunny side up eggs where the runny yolk creates a natural sauce. For breakfast serve alongside sourdough toast. For dinner consider pairing with a simple side salad dressed with vinaigrette to balance the richness. A dollop of sour cream or a sprinkle of fresh parsley adds a pleasant finishing touch.

Historical Context
Corned beef hash originated as a way to use leftover corned beef during lean times. Irish immigrants in America adapted traditional recipes using corned beef instead of the bacon they would have used in Ireland. The dish became especially popular during World War II when meat rationing made creative reuse of leftovers essential. Today it remains a comfort food staple in diners across America.
