Making Corned Beef Hash is straightforward if you follow these simple steps:

1. Prepare the Potatoes: Boil the diced potatoes in salted water until tender, about 10 minutes. Drain and set aside.
2. Sauté Onions: In a large skillet, heat the olive oil or butter over medium heat. Add the chopped onions and sauté until translucent, about 3-4 minutes.
3. Add Potatoes: Stir in the boiled potatoes, mixing well with the onions. Allow them to cook for an additional 5 minutes until they begin to crisp.
4. Incorporate Corned Beef: Add the diced corned beef to the skillet. Season with garlic powder, salt, and pepper. Stir to combine all ingredients.
5. Crisp the Hash: Press the mixture down into the skillet and let it cook undisturbed for about 5-7 minutes. This allows the bottom to get crispy.
6. Flip and Cook: Carefully flip the hash using a spatula (you can do this in sections) and cook the other side for another 5-7 minutes, until crispy and golden.
7. Serve with Eggs (Optional): If desired, fry or poach eggs to serve on top of the hash for an added protein boost.
8. Garnish and Enjoy: Once cooked, remove from heat, garnish with fresh parsley, and serve hot.

By following these steps, you’ll create a delicious Corned Beef Hash that is sure to impress!
