My husband’s poker buddies request this 4-ingredient Reuben pasta every single time they come over—and after one bite, it’s easy to understand why. It takes everything people love about a classic Reuben sandwich—savory corned beef, tangy sauerkraut, melty Swiss cheese, and comforting noodles—and turns it into a bubbling, scoopable oven-baked pasta casserole.
This recipe came about one night when the cards were already flying, everyone was hungry, and I didn’t have time to fuss over a complicated spread. I had leftover corned beef in the refrigerator, sauerkraut, Swiss cheese, and noodles in the pantry. I tossed them together, baked everything until hot and bubbly, and hoped for the best.
The result was pure comfort food.
The noodles soak up all those savory juices while the corned beef adds hearty flavor, the sauerkraut brings just enough tang, and the Swiss cheese melts into a deliciously gooey topping. Best of all, everything comes together in one baking dish, leaving you plenty of time to enjoy the company instead of standing over the stove.
If you love Reuben sandwiches, easy casseroles, cheesy pasta bakes, or old-fashioned comfort food, this is one recipe worth keeping close.
Ingredients
1. Cooked Corned Beef
Use about 2 cups cooked corned beef, cut into small pieces. Leftover brisket works beautifully, but deli-sliced corned beef is also convenient. If using deli meat, stack the slices and cut them into bite-size squares.
The corned beef provides the casserole with its signature salty, savory Reuben flavor.
2. Cooked Egg Noodles
Use about 12 ounces cooked egg noodles.
Egg noodles make the casserole hearty and tender while giving all the other ingredients plenty of surface area to cling to. Cook them just until tender rather than overly soft, since they’ll continue cooking in the oven.
3. Sauerkraut
Use about 1 1/2 cups sauerkraut, well drained.
Sauerkraut supplies the distinctive tangy, slightly sour flavor that makes this pasta unmistakably Reuben-inspired. If you prefer a gentler flavor, briefly rinse it under cold water and squeeze it dry before adding.
4. Swiss Cheese
Use about 2 cups shredded Swiss cheese.
Swiss cheese melts beautifully over the casserole, creating that irresistible golden, gooey cheese layer reminiscent of a hot Reuben sandwich.
How to Make Reuben Pasta
Step 1: Prepare the Oven and Baking Dish
Preheat your oven to 350°F (175°C).
Lightly grease a 9×13-inch baking dish so the pasta doesn’t stick and serving is easy.
Step 2: Cook the Noodles
Cook the egg noodles according to the package directions until just tender.
Drain them well. Avoid overcooking because the noodles will spend additional time in the oven.
Step 3: Combine the Reuben Ingredients
In a large bowl, combine the cooked egg noodles, chopped corned beef, and drained sauerkraut.
Gently toss everything together until the ingredients are evenly distributed.
Step 4: Add the Cheese
Fold in about half of the shredded Swiss cheese, reserving the rest for the top.
This helps distribute melted cheese throughout the casserole instead of leaving all of it on the surface.
Step 5: Transfer to the Baking Dish
Spoon the mixture into the prepared baking dish and spread it into an even layer.
Sprinkle the remaining Swiss cheese generously over the top.
Step 6: Bake Until Bubbling
Bake uncovered for approximately 20–25 minutes, or until the casserole is heated through and the cheese is completely melted and bubbling.
For an especially golden top, you can briefly place it under the broiler at the end, watching carefully so the cheese doesn’t burn.
Step 7: Rest and Serve
Let the casserole stand for about 5 minutes before serving.
This gives the melted cheese a chance to settle slightly and makes those generous, hearty scoops easier to serve.

Pro Tips for the Best Reuben Pasta
Don’t overcook the noodles. Cook them only until tender because they’ll continue cooking while the casserole bakes.
Drain the sauerkraut well. Excess liquid can make the pasta watery. Give it a good squeeze before mixing it into the casserole.
Want less tang? Quickly rinse the sauerkraut under cold water, then squeeze it very dry.
Use deli corned beef when needed. You don’t have to wait for leftover brisket. Deli-sliced corned beef works perfectly—simply stack the slices and cut them into small pieces.
Don’t skimp on the cheese. Swiss provides much of the casserole’s signature creamy, melty texture.
Make a smaller batch. Divide the mixture and bake half in an 8×8-inch baking dish if you’re cooking for a smaller household.
Keep leftovers safe. Refrigerate cooked corned beef at 40°F (4°C) or below and use it within 3–4 days. Refrigerate the finished casserole within 2 hours of baking and use leftovers within 3–4 days. When reheating, heat the center to 165°F (74°C). A splash of water or milk and a little foil over the dish can help prevent the pasta from drying out.
What to Serve With Reuben Pasta
For the full Reuben-inspired comfort-food experience, serve the casserole piping hot with toasted rye bread on the side.
A crisp green salad with a sharp vinaigrette is another excellent pairing because its freshness balances the richness of the pasta. Simple coleslaw works beautifully, too.
For game night, keep everything relaxed with iced tea, cold beer, or a light lager. And when dessert rolls around, there’s no need for anything complicated—a pan of brownies, cookie bars, or another easy dessert fits right in.
For an extra Reuben touch, put a small bowl of Thousand Island or Russian dressing on the table for anyone who wants to drizzle a little over their serving.
Make-Ahead and Leftover Tips
This casserole is particularly useful when you’re feeding a crowd because much of the preparation can be done ahead.
Prepare the pasta mixture, transfer it to the baking dish, cover it, and refrigerate it until you’re ready to bake. When working with refrigerated leftovers or prepared food, keep everything properly chilled and avoid leaving it at room temperature for more than 2 hours.
For smaller households, bake only half in an 8×8-inch dish and refrigerate the remaining mixture in a covered container for up to 2 days.
When reheating leftover casserole, bring the center to 165°F (74°C). Covering it with foil and adding a small splash of water or milk can help restore moisture.
