With St. Patrick’s Day approaching, there’s going to be a lot of people making Corned Beef. But do you know what’s even better than having corned beef for dinner? Having corned beef for BREAKFAST! If by a slim chance, you have any leftover corned beef after St. Patrick’s Day, then you’ve GOT to try this Corned Beef Hash recipe for breakfast the next morning.

If you don’t have any corned beef leftovers and you’d like to start by making your own corned beef first, then make sure to check out my Oven-Baked Corned Beef Recipe!

Corned Beef Hash is the most popular recipe for using up your leftover corned beef. And for good reason! First of all, you don’t have to wait until lunch or dinner to dig into that savory corned beef again. You can have it first thing in the morning with some potatoes, eggs and dare I say, a cup of Irish Coffee?  

I utilized all the shortcuts I could think of when it came to making this Corned Beef Hash recipe. Because let’s face it, after cooking up a storm for St. Patrick’s Day, the last thing I want to do the next morning is make a big extravagant breakfast. Luckily, this corned beef hash recipe is soooo easy to make while still tasting like a gourmet, restaurant-style breakfast.

The number one shortcut I used when making this corned beef hash is buying frozen diced Potatoes O’Brien. The potatoes are already diced into the perfect shape and they include a mix of onions and bell peppers. This saves so much time on chopping fresh veggies and decreases the cook time dramatically.

Using leftover corned beef adds to the ease of this recipe as well. Since the corned beef is already precooked, you simply have to dice it up and throw it in a skillet to heat through. You’ll then mix it in with the potatoes O’Brien you made earlier creating a skillet-full of mouthwatering, homemade Corned Beef Hash.
