We don’t know what we look forward to more when it comes to St. Patrick’s Day eats, the actual Corned Beef and Cabbage or the subsequent leftover meal that follows: this Easy Corned Beef Hash. It’s such a hearty, comforting breakfast: meat, potato and eggs. It’s such a classic meal and the best part is that the components are mostly already cooked so it’s just a matter of heating them all up together and topping with an egg, if desired. If you don’t have leftover corned beef laying around, trust us this breakfast is totally worth cooking corned beef for.

This is one of those recipes that really is more of a guideline. If you have leftover carrots, or onions or root vegetables that were cooked with your corned beef you can feel free to add those in! This can also work with any other leftover beef you may have, though it won’t have that classic flavor as it does when cooked with the corned beef. If you have leftover roast beef, pot roast or even steak, you can make this work. If you don’t have any leftover potatoes you can cook up some fresh. Just dice up some potatoes and boil for about 12-15 minutes, or until fork tender. They brown better when they are cold, but fresh cooked will work in a pinch.

How to Make Corned Beef Hash

How do you make corned beef hash from scratch:

  1. Cook some onions
  2. Add cooked corned beef and potatoes and cook for 5 minutes undisturbed, and then flip and cook another 5 minutes
  3. Season with garlic powder and pepper, and add salt if needed.
  4. Serve with eggs!

Why is corned beef so salty?

We talk extensively about the process for brining your own corned beef here, and then go into details about how to cook it from scratch here. If cooked properly (meaning rinsed really well and cooked in enough water) corned beef shouldn’t be overly salty, but when making corned beef hash you definitely want to taste the dish before adding any additional salt!

  2. To make fully dairy free feel free to sub in ghee or additional oil in place of the butter.
