When St. Patrick’s Day comes around, I make sure to save some of my leftover slow cooker corned beef to make this easy and flavorful dish. I also like to whip up some easy Irish soda bread for an amazing breakfast!

One of the best parts of St. Patrick’s Day is the leftovers! I always make sure to prepare plenty of corned beef so I’ll have some on hand for sandwiches and this delicious corned beef hash. It’s simple, yet totally satisfying.
Corned Beef Hash INgredients
When you make corned beef hash you will need butter, olive oil, onion, potatoes, corned beef, garlic, eggs, parsley, salt and black pepper.

How do you make corned beef hash?
This recipe starts with onions, which are cooked in a combination of butter and olive oil until softened. Potatoes go into the pan with a little salt and black pepper, and cook until golden brown. The next step is to add cubed cooked corned beef. The potatoes and corned beef cook together until everything is crispy and browned. Add a fried egg and a sprinkling of parsley and you’ll be ready to eat.

Tips for the perfect hash
- Cut the potatoes into 1/2 inch cubes – larger pieces will take longer to cook in a skillet.
- If you don’t have leftover corned beef brisket, you can buy prepared corned beef at the deli counter of most grocery stores. Cut your corned beef into 1/2 inch cubes so that it’s the same size as the potatoes.
- I like to use peeled Russet potatoes, but other varieties will also work such as Yukon Gold potatoes or red potatoes. You can even use sweet potatoes for a different twist!
- This dish can be served for breakfast, brunch or even as an unexpected dinner option.
- While I prefer to serve my eggs over easy to get that runny yolk, I’ve also served this hash with a pile of scrambled eggs on top with great results. Poached eggs are also a great option.

RECIPE FAQs
Corned beef hash is often served as a morning meal, and pairs well with other Irish favorites such as sauteed cabbage or Irish soda bread. A traditional Irish breakfast contains items such as sausage, bacon, baked beans, mushrooms and tomatoes, which all would be great served alongside this hash. You can even pair your hash with a simple green salad or a steamed vegetable such as asparagus, green beans or broccoli.
Corned beef hash can be frozen in an airtight container without the egg. It will last in the freezer for 2 months. Simply reheat it in a skillet at medium-high heat until it is hot.

I have now served this several times for breakfast at our Bed & Breakfast business. Along with real homemade Russian Dressing drizzled on top. It is a big hit for the guests.
PLEASE reply back since I’m going to make this on Sunday (5 more days). Can I give leftover cooked corned beef? If so, do I just toss with the potatoes for a couple of min instead of 8-10? I think that would overcook or dry out the CB. What do you think about adding diced sausage to the hash? Yay or nay?
Can I USE leftover corned beef?
Yes that works!
This recipe assumes that you’re using leftover cooked corned beef. I cook it for 8-10 minutes so that it gets crispy and browned on the outside, but if you want to cook it less that’s fine. I think sausage would be ok but I haven’t tried it myself.
