Reuben Casserole

Reuben casserole is a great way to use up leftover corned beef or to make a quick weeknight meal using pastrami from the deli. It has all the flavor of a Reuben sandwich, but very little hands-on time. Just mix it together, and pop it in the oven!

Reubens are a family favorite at my house. This boldly flavored sandwich is layered with tangy sauerkraut, earthy Swiss cheese, meat, and thousand island dressing, pressed between hearty rye bread and grilled until golden and crispy. What’s not to love? Well, maybe one thing.

Making one sandwich after the other usually means that either I’m standing at the stove grilling the next sandwich or my husband is while everyone else eats. For nights when you want the flavor of a Reuben, without spending your evening at the stove, this Reuben Casserole is here for you.

How to Make Reuben Casserole

Layer the bottom of the casserole dish with cubes of rye bread (hearty seeded rye is my favorite); mix the rest of the ingredients in a bowl; spread it over the cubed bread, and top it with breadcrumbs. The cheese melts, and all the flavors meld together without needing to stand at the stovetop.

What Meat Is Best for Reuben Casserole?

If I make this around St. Patrick’s Day, I always use leftover corned beef, but it’s a quick and simple weeknight dinner any time of year. If I don’t have leftover corned beef on hand, I just buy pastrami at the deli counter.

I prefer deli pastrami to deli corned beef, because the flavor is more pronounced and stands up better to all the competing flavors in this casserole. My deli will give me a sample; I’m sure yours would too. Don’t be afraid to ask to try a piece, then decide for yourself—corned beef or pastrami. They cost about the same.

What to Serve With Reuben Casserole?

This is a pretty rich dish, and definitely not heavy in the vegetable department. I would serve this with a simple vegetable side like green beans, asparagus, or broccoli. A light, easy salad is always a great way to round out dinner.

Make-Ahead Tips for Reuben Casserole

Casseroles are the perfect make-ahead meal. Make this recipe the night before, cover, and keep in the fridge unbaked, then just pop it in the oven when you get home from work. You can also bake it completely, then just reheat it in a 350°F oven until it's warmed through.

Can You Freeze Reuben Casserole?

Yes, you can! Feel free to assemble the entire casserole, wrap it in plastic wrap and aluminum foil, and keep it in your freezer for up to three months.

Just take it out the night before you want to eat, and let it thaw in the fridge overnight. Pop it in the oven when you get home from work, and bake as if it had never been frozen.

You can also bake the casserole as directed before freezing. Let it cool completely, then wrap and freeze the baked casserole. It will keep for up to three months. When ready, thaw in the fridge overnight and reheat in a 350°F oven.

Reuben Casserole

Prep Time 30 mins
Cook Time 45 mins
Total Time 75 mins
Servings 6 to 8 servings


  • 8 slices (9 ounces) seeded sliced rye bread
  • 8 ounces cream cheese, room temperature
  • 1 1/2 pounds sliced pastrami or corned beef (from the deli or homemade)
  • 8 ounces sliced Swiss cheese
  • 22 ounces (2 3/4 cups) sauerkraut, drained
  • 1 1/2 cups Thousand Island dressing
  • 2 teaspoons caraway seeds
  • 1/2 teaspoon kosher salt
  • Butter for the baking dish


  1. Prepare the pan and heat the oven:

    Butter a 9x13 baking dish and preheat the oven to 350°F.

  2. Cube and crumb the bread:

    Take 6 slices of the bread and cut them into 1-inch cubes. Ultimately, you need enough bread to cover the bottom of your baking dish. If you're bread isn't pre-sliced, you might need more to do this.

    Take the remaining 2 slices of bread and pulse in a food processor until fine crumbs are formed.

  3. Chop the meat and the cheese:

    Chop the pastrami (or corned beef if you’re using) into bite sized pieces. I do this by stacking it and cutting the meat first in strips, then I cut across the strips to form rough squares. It doesn’t need to be perfect. It’s a casserole.

    Stack the cheese slices one on top of the other, then cut it in strips, and then cut across the strips into squares.

  4. Make the filling:

    In a large bowl, add the cream cheese and smoosh it with a spoon or spatula to soften and break it up a bit. Add the meat, Swiss cheese, sauerkraut, thousand island dressing, caraway seeds, and salt. Stir to combine, making sure you fully incorporate the cream cheese.

  5. Layer the casserole:

    Place the cubed bread on the bottom of your 9x13 baking dish (slice and add more cubes if needed to make a full layer). Then spoon the filling over the top of the bread. Spread it out as evenly as possible. Sprinkle the breadcrumbs over the top.

  6. Bake the casserole:

    Place the casserole in the oven and bake for 40-45 minutes until the crumbs are toasted and the casserole is heated through.
