I love love great leftover recipes of all kinds. If you know me you have heard over and over again how I hate wasting food, that is where our leftover corned beef recipes comes into play. Not just for after the holiday but year round too.
What Can I do With Leftover Corned Beef?
Whether you made air fryer corned beef, in the oven or our Traeger corned beef and cabbage the night before any of these will work for a 2nd meal. You can even use canned corned beef to make any of these for a quick and fabulous comfort food bite year round.
I will share a quick homemade air fryer corned beef hash below you can make on the stove in a skillet or air fryer too. That is the most popular of course and what you would think of first. I have a few other ideas though beyond that we will link to throughout this post. From adding it into a casserole, to stuffing a potato it just shouldn’t be wasted.

What Can be Made with Corned Beef and Potatoes?
Typically people are going to make a breakfast dish that is savory called a hash. This is half meat and half cubed potatoes typically with chopped vegetables like onions and/or bell peppers thrown in there.
I do love using a casserole dish to make Leftover Corned Beef Casserole when I am baking my veggies so everything is ready at the same time.

How to reheat leftover corned beef
Pour in your diced leftover baked corned beef into the air fryer preheated to 380F with some small diced potatoes, onions and bell peppers that have been coated with olive oil. Air fry for 5 minutes, toss and cook another 5 minutes until warmed and as crispy as you’d like. Sprinkle with salt and pepper if desired and serve.
You can also rewarm it in some broth with veggies to make a whole new meal like we did with our Corned Beef and Cabbage Soup for dinner.
Leftover Corned Beef Recipes with Pasta
Think about any of our easy beef recipes, you could use this type with any of those just the same. Make them all with canned corned beef too if that is all you have. Like let’s say you wanted something super cheap and easy. You could make boxed mac and cheese and throw this right in, or make homemade leftover brisket mac and cheese with it.
Just adds protein and a TON of flavor into the mix, all creamy and delish. You can fry it up in a pan with frozen hash browns with a fried egg on top. Served over rye bread is a fabulous breakfast for sure. Want to use this for a version of taco Tuesday?? Do just that, wrap your warmed pieces in tortillas with freshly made pressure cooker fried cabbage for a twist of Mexican and Irish cuisine!!

Beyond Corned Beef Sandwich Recipe, maybe this year you’ll create a whole new meal that you never would’ve thought of before when thinking outside of the box like this.
What can you make with leftover corned beef other than sandwiches?
You could dice and stuff it into egg rolls with some cabbage slaw. Fry or air fry from there. I mean even avocado toast would be amazing with this diced protein crisped up and layed on top of that. Whip up your favorite reuben dip and add this meat in there in little bits to add a ton of flavor. Baked in the oven this is great with crackers or slices of bread to scoop it up.
Really any favorite day after meal can use it. You may have a dish that normally uses chuck roast or even chicken. By just swapping out the meat will make it totally different! If you come up with a whole new one we haven’t mentioned here let us know below! We love to try your ideas too for sure.

How long is leftover corned beef good for?
Leftover corned beef can last 3-4 days in the refrigerator until it needs to be eaten. Now if you cooked a frozen corned beef brisket in slow cooker I wouldn’t freeze again. If it started out fresh then you could store in freezer bags and keep for a few months this way. This is our first one we will share, you’ll need;
What to do with leftover liquid from corned beef?
It makes a great broth with tons of flavor!! Especially if you are making a soup out of your meat keep the drippings in a jar in the fridge. When you are ready to make a new meal, or reheat it as is, pour some on top to keep it moist or use liquid in our soup recipe to add a ton of taste.
