Leftover Corned Beef Casserole

We have a lot of Leftover Corned Beef Recipes on our site. Why?? I hate wasting food so I like to have a few options after making a large piece of meat. This beef brisket usually yields more than your family would eat in one sitting so year after year I make something new to share with y’all.

I mean I am sure you always make Leftover Corned Beef Sandwich the day after the holiday right? Boooooring. It’s a given and if you want to go simple with little to no prep then yes go for that one. If you want to stretch your meat though a casserole is the way to go. My grandmother who had 5 kids taught me that. 😉

Easy Corned Beef Casserole with Noodles

I offer 2 ways you can make this. If you don’t like rye bread or don’t have any on hand you could boil shell, macaroni or spiral noodles to al dente and use those as layers instead. Half would lay on the bottom and the other half after the meat, sauce and cheese layers so it’s all sandwiches together.

I wouldn’t use egg noodles as they cook very fast and even if you cook them halfway they break apart more than other varieties so the texture just isn’t as great. I will usually choose small shells so it’s easy to eat and cook until they are tender but still a bit firm as in the baking process in the oven they will soften more.

• Thinly sliced corned beef, sauerkraut and Swiss cheese
• 1 c Russian dressing
• Mayonnaise
• Dijon mustard
• 1 tbsp worchestershire sauce
• Caraway seeds optional, best if making reuben casserole style
• Loaf rye bread sliced, or use 16 oz. of boiled al dente noodles

If you aren’t sure about using the shredded fermented sauerkraut this is How Long to Boil Cabbage instead. Do it quick in this case just to barely make it to wilt knowing that it will get heated more with the other ingredients. If you have ever blanched it you would basically want to do that, drain and is a great substitute if you’d prefer.

Reuben Casserole

If you wanted to start from scratch, this is How to Cook Corned Beef in the Oven but in this case leave the mustard sauce off. I mean if it’s there you will just get a more intense dijon flavor in the dish so not a game changer if you did.

• Preheat the oven to 375°F (190°C) and grease a 9×13 inch baking dish.
• In a medium bowl, mix together the Russian or Thousand Island dressing, mayonnaise, Dijon mustard, and Worcestershire sauce.
• Place half of the sliced rye bread if making reuben sandwich style (or al dente noodles if you’d prefer) in the prepared 9×13″ casserole dish
• Follow by half the diced beef, layer half sauerkraut, Swiss cheese, and half of the dressing.
• Repeat the layers with the other half, finishing with a generous sprinkle of Swiss cheese on top.
• Bake in the preheated oven for 27 – 30 minutes or until cheese is golden brown.
• Allow the casserole to cool for a few minutes before serving.
• Slice and enjoy as is or with a little drizzle of Mustard for Corned Beef over the top!!

Best Leftover Corned Beef Recipe

You could make this with Canned Corned Beef if that is all you have but the texture is totally different, and not as good. The real deal is your best bet I tell you.

SO if you have some left after making Dutch Oven Corned Beef for the holiday I hope this makes your mouth water and your kids want seconds. If you come up with another tweak we haven’t yet tried or mentioned here let us know below!

One more to share. If you still have more on hand I would suggest making our Leftover Corned Beef and Cabbage Soup. This one is healthy without cheese or heavy cream but rather in a light broth with cabbage and other vegetables.
