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

1. Prepare the Potatoes: Start by boiling the diced potatoes in salted water until just tender, about 5-7 minutes. Drain and set aside.
2. Sauté the Onions: In a large skillet, heat the vegetable oil or butter over medium heat. Add the chopped onions (and bell pepper, if using) and sauté until they are translucent, about 3-4 minutes.
3. Combine Ingredients: Add the diced corned beef and cooked potatoes to the skillet. Stir to combine everything evenly.
4. Cook the Hash: Press the mixture down into an even layer in the skillet. Let it cook without stirring for about 5-7 minutes until the bottom is golden and crispy.
5. Flip and Cook Again: Carefully flip sections of the hash to allow the other side to crisp up. Cook for an additional 5-7 minutes until golden brown.
6. Season: Season the hash with salt and pepper to taste. Stir gently to combine.
7. Serve: Remove from heat, garnish with fresh parsley or chives if desired, and serve hot. For an extra treat, top with fried or poached eggs.

By following these straightforward steps, you’ll have a delicious Homemade Corned Beef Hash ready to delight your family or guests.
