Ingredients in a Reuben Noodle Casserole

Corned Beef – If you happen to have leftover corned beef, it’s perfect for this recipe. If you don’t have leftovers, ask the deli counter to slice corned beef extra thick.

Cheese Sauce – The cheese sauce for this casserole sauce resembles mac and cheese with the flavors of a Reuben sandwich- Swiss cheese sauce, a bit of Dijon mustard, and Worcestershire sauce.

Pasta & Cabbage – The base of this Reuben noodle casserole consists of pasta and cabbage. If you have leftover cabbage from corned beef, use that in place of fresh cabbage.

Variation

You can replace the pasta in this Reuben noodle casserole with 3 cups of leftover potatoes or diced boiled or fried potatoes. Add the potatoes to the casserole dish and layer the cooked cabbage, sauerkraut, and the onion/corned beef mixture on top. Pour the Swiss cheese sauce over top, sprinkle with breadcrumbs, and bake until hot and bubbly!

How To Make a Reuben Noodle Casserole

  1. Cook onions and leftover corned beef (or ham in a pinch) in butter per the full recipe below.
  2. While the onions are cooking, prepare the cheese sauce.
  3. Boil pasta and cabbage and place them in a casserole dish. Add sauerkraut, the corned beef mixture, and the creamy Swiss cheese sauce.
  4. Top panko and parmesan to give it a crispy topping and bake until golden and bubbly.

TOPPING TIP: If you’d like to incorporate the flavor of rye bread, place a piece or two in a blender or food processor. Pulse a few times until it forms crumbs, and use them in place of the panko.

Once it comes out of the oven, garnish with chopped dill pickles!

  1. I made this today. The only thing I changed was that I halved the recipe because there are only two of us and we’re not big eaters.
    I absolutely loved it, I couldn’t stop eating it. My husband on the other hand, not so much. But, he doesn’t like anything.. lol…so his opinion doesn’t count.
    If you like a reben sandwich you will like this. Great recipe, it’s a keeper. :)5 stars

    1. Haha thanks for the giggle, Maxine I am so glad you enjoyed it, especially since it’s your opinion that counts

  2. Can’t wait to make this. Getting my corned beef this weekend. Only thing I will leave out is the sauerkraut – just do not like that stuff. Will probably substitute just regular chopped cabbage.5 stars

  3. Miss Holly I am so delighted with these so called weird recipes some of my family think they are. They are sooo delicious and healthy. Thank you 5 stars

  4. Tried with serving sauerkraut on the side and not incorporating it into the casserole. It did not work for our family. Disappointing, it sounded really good!!

    1. Sauerkraut is a unique taste, so we understand, but this casserole is still delicious even without it. You can also replace it with a little extra cabbage if you’d like.

  5. This recipe is addictively good! I’m always looking for something a bit different and knew, reading the ingredients, it would be tasty. It is even better than imagined. Thank you!5 stars

  6. This casserole is delish! I wasn’t going to make it because the reviews I read all said “sounds great” or “can’t wait to make it” so I was very skeptical. I’m glad I didn’t let that deter me because I followed the recipe exactly and it’s perfect. I’ll definitely make it again!5 stars

  7. The Rueben Slider ingredienys can be layered w/t one more meat @ cheese & the left overs from that can be placed in the Corn Beef Casserole. Thank you for recipes.5 stars

  8. I’m so excited to try this recipe out also thinking about adding some rye swirl bread crumbs to the top looks delicious thank you

  9. This Reuben Casserole sounds really good! My fiance will love the idea of making the casserole instead of a sandwich!)5 stars

  10. Mac & cheese meets reuben sandwich? Um yes please! Count me in! This looks so delicious and what a great way to use up leftover corned beef!5 stars

  13. That panko Parmesan topping has me swoooooning hard over here! What a fun spin on a classic sandwich, and such a gorgeous combination with pasta. YUM!

  14. Wow and yum are the two words that come to mind when looking at your pictures and reading about this recipe! Nice job! 5 stars

  18. The reuben is one of my all time favorite sandwiches! The sauce sounds heavenly too!5 stars

  19. My husband goes ga-ga over Reuben sandwiches! I like them but usually, have to substitute the bread since I’m not a Rye or Pumpernickel fan. I can not WAIT to tell him about your Reuben casserole! Even I will eat it without having to substitute anything!!5 stars

  20. Hmmm….casserole or sandwich, casserole or sandwich? OMG that is a difficult question. Since both are delicious….I would make this delicious casserole AND sandwiches. Then I would be set for the week.5 stars
