Dice peeled russet potatoes until you get 4 cups. Then boil them just until fork-tender, 5-10 minutes. Drain well.

In a large skillet over medium heat, add 4 tablespoons of the butter. Once melted, add the potatoes, onion, salt, and pepper. Cook, occasionally stirring, until the onions are softened and the potatoes and onion start to brown, 8-10 minutes.

Add the chopped corned beef, garlic powder, and onion powder to the pan. Stir to combine.

Using the back of a spatula, press the mixture down to form an even layer. Cook for 3-5 minutes or until a golden crust begins to form on the bottom.

Scrape the bottom of the pan and flip up the hash, so the crusty part is on top. Add the remaining butter, and mix it in.

Again, using the spatula, press the hash down to form an even layer. Cook another 3-5 minutes until golden on the bottom. Continue doing this until you reach your desired browning. We usually do this 3 times. Then serve!.
