Reuben Casserole is a family favorite with layers of warm egg noodles, tangy sauerkraut, thousand island dressing, corned beef, gooey cheese, and buttery toasted rye bread. It's like a reuben sandwich made even better in one dish for easy clean up!

Reuben Casserole
Sauerkraut, Thousand Island dressing, and rye bread are usually not my favorites on their own. But combined with corned beef, gooey cheese, and warm egg noodles in this reuben casserole recipe, I couldn't love them more.
It's like a reuben sandwich, made even better! I love the addition of egg noodles to this casserole because they are so comforting and filling. And the cheese melts when it bakes around the toasty rye bread. The tangy sauerkraut and thousand island and salty corned beef work to break up those comfort food flavors to create a truly amazing dish.
We make slow cooker corned beef and cabbage for St. Patrick's Day every year, and there is no better way to use up the leftovers!

Can you Freeze Reuben Casserole?
Yes, you can freeze this reuben casserole! Follow steps 1 through 7 in the recipe. Do not pour on the butter. Instead, place a lid on your baking dish, and freeze.
It can be frozen for up to one month in a standing freezer or 3 months in a deep freezer.
When you're ready to use the casserole, place it in the refrigerator to thaw overnight. Then complete the recipe with the butter drizzle, and bake.

What to Serve with Reuben Casserole
This Reuben Casserole is pretty much a meal all on its own. It already has meat, dairy, and carbs.
For sides, I like to keep it simple and fresh, like a simple salad with vinaigrette dressing, roasted carrots, steamed broccoli, or mixed vegetables.

Reuben Casserole
Ingredients
- 16 ounces sauerkraut (drained with most of the liquid squeezed out)
- 6 ounces egg noodles cooked to package instructions
- 1 teaspoon salt
- ½ teaspoon black pepper
- 1 pound chopped corned beef
- 1 cup Thousand Island dressing
- 12 slices Swiss cheese
- 4 slices rye bread torn into pieces
- 2 tablespoons butter melted
Instructions
- Preheat oven to 350°F.
- Place sauerkraut and cooked noodles in the bottom of a 9"x13" baking dish. Stir to combine.
- Season sauerkraut mixture with salt and pepper.
- Layer corned beef over sauerkraut mixture. Spread evenly.
- Spread Thousand Island evenly over corned beef layer.
- Layer Swiss cheese over Thousand Island dressing.
- Top with rye bread pieces.
- Drizzle melted butter over bread.
- Bake for 30 minutes.
Notes
- To squeeze the sauerkraut, drain it first in a colander or strainer. Then layer 3 or 4 paper towels, and transfer the sauerkraut onto them. Pick up the paper towels in a bundle and gently squeeze the sauerkraut over the sink, so that there's less liquid but it's not totally dry.
- What kind of corned beef? I used leftover corned beef from my slow cooker corned beef and cabbage recipe for the photo shoot and video. You can also grab a pound of sliced corned beef at the deli counter of your grocer if you don't have any leftovers.

I loved everything about this recipe! The kids gobbled it up too, so I didn't have as much leftover as I would have liked.
Delish!

I would have never thought of this! Great idea to make a favorite sandwich into a casserole, and just in time for St. Patricks Day.

I love the idea of taking a Reuben and turning it into a casserole! After all, it is a delicious sandwich why not? I know my whole family will love this when I make it for them.
Dannii says
Now this looks super comforting. Great for feeding a crowd too.
Deb H says
When I get a large pumpernickel loaf and have leftovers, I make crumbs in the food processor and freeze them to use (mixed with a tad of melted butter) as a substitute for the rye. It gives the top a different mouth feel with some crunchy bits but is equally delicious!
Michelle says
I love this tip! Thank you for sharing!

Everyone at my house really enjoyed this!! Thanks for the recipe!

Jennifer says
OK I'm in love. We try a new recipe each week and this Reuben Casserole was this week's pick. Not flavors I'd normally put in a casserole but it works and the empty dish is proof of how good it was! A keeper!
Laura Cox says
OMG! This is amazing!! I had leftover corned beef from Sunday and really didn't want to do hash again. I found this and made it last night. My husband and I both thought it was crazy good! I had a couple wedges of cabbage leftover, so I chopped them up and added to the noodles and sauerkraut. This is a keeper for post St. Patrick's Day and probably sooner than that! Thanks!
Michelle says
Yes! It's one of our family favorites too! Glad you enjoyed it!
