Air fryer

1. Preheat your air fryer to 375 degrees Fahrenheit.
2. Place the corned beef hash in the air fryer basket, making sure to spread it out evenly.
3. Cook for 10 minutes, shaking the basket halfway through.
4. Increase the temperature to 400 degrees Fahrenheit and cook for an additional 5 minutes or until the desired crispiness is achieved.
5. Remove the corned beef hash from the air fryer and enjoy!

Skillet

1. Preheat a regular large skillet or a well-seasoned cast iron skillet over low-medium heat.
2. Add 1 tablespoon of oil or butter to the pan and heat. Vegetable oils will be best for not changing the flavor of the hash. Butter works too, but butter burns more easily than an oil with a high smoke point like vegetable oil.
3. Add the corned beef hash to the skillet and spread it out in an even layer.
4. Increase to medium-high heat and let the hash cook for 2-3 minutes or until it begins to brown.
5. Flip the hash over and press down on it with a spatula, then let it cook for another 2-3 minutes.
6. Continue flipping and pressing until the hash is crisp and browned on both sides.
7. Serve the hash hot, and enjoy!

Oven

1. Preheat the oven to 375 degrees F.
2. Grease a baking sheet with butter or oil.
3. Place the corned beef hash in the dish.
4. Bake for 25 minutes or until the hash is golden brown and crispy.
5. Serve hot. Enjoy!
