Corned Beef Casserole

Jump to Recipe

I have always loved the flavor of corned beef. And it is usually served in a hash or skillet type meal. So I wanted to try it with some pasta instead and the outcome was unreal! Corned Beef Casserole will take you back to your childhood with the comfort food vibes. A simple but delicious, creamy, cheesy casserole that is going to please the whole family.

The cream of mushroom recipe included in this dish is the real star. By making it from scratch you can get bigger chunks of mushroom in it. If you don’t have time or you just prefer it, you could replace with a couple of cans of cream of mushroom soup. But I would advise that you warm it up on the stove with some added milk before you add it to the baking dish. You want it to thin out a little bit so that it really coats everything well.

I used garlic croutons to make a nice crispy top layer. You could also use french fried onions, breadcrumbs, crushed up ritz crackers, or crushed up potato chips. You just want that crunchy texture element in this particular casserole. I actually think most casseroles should have a slightly crunchy or crispy element to them. It takes it from meh to wow real quick. I usually pick a garlic crouton because it is already seasoned so it is a real time saver.
