What Makes This Corned Beef Casserole So Good?

This Reuben casserole recipe is so easy and much less messy than traditional Reuben sandwiches. Let’s face it, a Reuben sandwich is a distinguished mess!

You get stacks of corned beef and big pulls of cheese, and then you have to catch the sauerkraut spilling over the sides, and hello, drips and drips of that Thousand Island… This is why a Reuben bake is such a perfect solution.

Corned Beef Casserole Ingredients

This is a casserole version of the famous deli sandwich – essentially, it’s like the sandwich, only layered and baked. Here’s what you need to make this Reuben casserole recipe.

For the Base Layers:

• Sauerkraut – Provides the essential tangy, fermented cabbage flavor that defines Reuben character
• Fresh tomatoes – Add moisture, sweetness, and fresh contrast to the rich ingredients
• Thousand Island dressing – Delivers the signature creamy, tangy sauce that ties all flavors together

For the Protein and Cheese:

• Sliced corned beef – Creates the hearty foundation with its distinctive seasoned, tender texture
• Shredded Swiss cheese – Melts beautifully and provides the classic nutty, creamy flavor profile

For the Bread Component:

• Canned biscuits – Transform into a golden, fluffy topping that replaces traditional rye bread
• Crisp rye crackers – Add authentic rye flavor and textural contrast when crushed on top
• Caraway seeds – Contribute the distinctive earthy, slightly peppery flavor associated with rye

Ingredient Notes

You can purchase corned beef deli meat from the deli section or make your own if you are really ambitious. Note that the meat should be cooked before using in this Reuben bake.

Sauerkraut is fermented cabbage that adds acidity and flavor. Make sure to drain your sauerkraut well and dab it with a paper towel to get it as dry as possible.

How to Make Reuben Casserole

If you have ever made Reuben sandwiches, you know that it can be time-consuming to make each one. So, think of this Reuben bake as creating a whole load of Reuben sandwiches in just a few simple, quick steps. You get all the same flavors served warm and it’s easy to slice up and serve!

1. Spread out the sauerkraut on the bottom of an 8×12-inch casserole dish.
2. Distribute the tomato slices over the sauerkraut.
3. Dot or drizzle the dressing over the tomatoes.
4. Cover with corned beef slices.

5. Sprinkle cheese on top. Bake for 15 minutes, and then remove the dish from the oven.
6. Separate and divide each biscuit into 3 pieces. Place the biscuit pieces on top of the casserole, overlapping slightly.
7. Sprinkle crushed rye crackers and caraway seeds on top.
8. Bake at 425°F until the biscuits are golden, about 12 to 17 minutes. Serve and enjoy!
