Place the diced potatoes in a pot of boiling water and cook until fork-tender, about 5-10 minutes. Drain well and set aside.

Melt 4 tablespoons of butter in a large skillet over medium heat. Add the drained potatoes, diced onions, salt, and black pepper. Cook, stirring occasionally, until the onions soften and the potatoes begin to brown, about 8-10 minutes.

Stir in the chopped corned beef, garlic powder, and onion powder. Mix everything well to combine.

Using a spatula, press the mixture down into an even layer. Let it cook undisturbed for 3-5 minutes, or until a golden crust forms on the bottom.

Scrape the bottom of the pan and flip the hash so that the crispy side is on top. Add the remaining 2 tablespoons of butter and mix it in.

Press the hash down again and cook for another 3-5 minutes until golden brown. Repeat this process 2-3 more times until you reach your desired level of crispiness.

Once crispy and golden brown, remove from heat and serve hot.
