Ingredients Equipment Method Notes

Ingredients
  

  • 2 lbs cooked and chilled corned beef, diced into 1/4- to 1/2-inch cubes
  • 1.5 lbs cooked and chilled potatoes Russet or Yukon Gold
  • 1 large yellow onion, finely diced
  • 2 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 1 tablespoon Worcestershire sauce
  • 1/4 cup fresh parsley, finely chopped
  • Kosher salt, to taste
  • Freshly ground black pepper, to taste
  • 4 to 8 large eggs, for serving optional

Equipment

  • Large 12-inch Skillet (Cast-Iron or Non-Stick)
  • Sturdy Spatula
  • Chef's knife
  • Cutting board

Method
 

  1. Prepare your ingredients: Ensure your cooked corned beef and potatoes are cold, then dice them into uniform 1/4- to 1/2-inch cubes. Finely dice the yellow onion and chop the parsley.
  2. Sauté the aromatics: Place a large 12-inch non-stick or well-seasoned cast-iron skillet over medium heat. Add the butter and olive oil. Once the butter is melted and foaming, add the diced onion and sauté for 5-7 minutes, until soft and translucent.
  3. Combine the hash: Add the diced corned beef and potatoes to the skillet. Drizzle with Worcestershire sauce, then sprinkle with the chopped parsley, a pinch of salt, and a generous amount of black pepper. Gently stir until all ingredients are well-distributed.
  4. The critical crisp-up: Using a sturdy spatula, press the hash mixture down firmly into an even, compact layer. Reduce the heat to medium-low. Cook undisturbed for 15-20 minutes, until a deep, golden-brown crust forms on the bottom. Resist the urge to stir.
  5. Prepare the eggs: While the hash is crisping, cook 4 to 8 eggs to your preference. Fried sunny-side up or poached eggs with runny yolks are ideal.
  6. Serve: To serve, you can either carefully flip the entire hash onto a large plate or cut it into wedges and serve directly from the skillet. Top each portion with one or two cooked eggs and garnish with a little extra fresh parsley. Serve immediately.

Notes

Key Technique: The secret to the perfect crust is the 'press and crisp' method. After combining the ingredients, press the hash firmly into the pan and let it cook undisturbed on medium-low heat. This allows a magnificent, uninterrupted crust to form.
Ingredient Tips: Using chilled, pre-cooked corned beef and potatoes is essential. This prevents them from becoming mushy and helps each piece hold its shape for the best texture.
Variations & Swaps:
- Meat: Leftover pot roast, brisket, or pastrami can be used for a different flavor profile.
- Potatoes: Cooked sweet potatoes, parsnips, or carrots can be substituted for a sweeter hash.
- Aromatics: Add 1/2 cup of diced bell pepper or a minced jalapeño along with the onions for extra flavor or heat. A teaspoon of fresh thyme or rosemary also adds a wonderful earthy aroma.
- Indulgence: Sprinkle 1 cup of shredded sharp cheddar or Gruyère cheese over the top during the last 2 minutes of cooking and let it melt.
