Corned Beef Mac & Cheese

Christine Schnepp


I use the leftover corned beef after St. Paddy's Day to make this yummy dish. Very simple and your family will love it!

The more cheese in macaroni and cheese the better ... and this recipe is super cheesy. The mix of cheddar and Monterey jack is perfect. Cream of mushroom soup gives the cheese sauce a lovely velvety texture. Corned beef adds a salty flavor and a great way to use leftover corned beef. The Test Kitchen
