📋 Ingredients for Reuben Bake
You only need a handful of simple ingredients to whip up this Reuben casserole recipe:
- 2 cans crescent rolls
- 3 Tbsp dijon mustard
- ½ lb. sliced corned beef
- ½ lb. Swiss cheese
- 1½ cups sauerkraut, squeezed dry
- ¾ cup Thousand Island dressing
- 2 Tbsp melted butter
Pro Tip: Squeeze That Kraut!
Make sure you really squeeze the liquid out of your sauerkraut — nobody wants a soggy Reuben Bake casserole!

🥣 How to Make Reuben Bake Casserole
Step 1: Preheat & Prep
Preheat your oven to 375°F. Grab a 9×13 baking dish and give it a light spray of cooking spray.
Step 2: Layer the Bottom
Open your crescent roll dough and press half into the bottom of the dish, pinching seams together to form a solid crust. Spread the dijon mustard evenly over dough. This creates the first buttery layer of your Reuben Crescent Bake.
Step 3: Build the Layers
Now the fun part — layering all that Reuben goodness!
- Start with the corned beef, spreading it evenly across the crust.
- Lay down the Swiss cheese slices on top.
- Spread the squeezed-dry sauerkraut evenly.
- Drizzle that Thousand Island dressing over the top for that signature tangy kick.
Step 4: Top It Off
Unroll the second can of crescent rolls and place it on top, pinching seams and edges to seal.
Step 5: Brush & Bake
Brush the top with melted butter and pop it into the oven for about 20-25 minutes, or until golden brown and bubbly.
Step 6: Slice & Serve
Let your Reuben Bake casserole cool for a few minutes before slicing into squares. Serve with extra Thousand Island dressing for dipping!

Helpful Tips for the Best Easy Reuben Bake Casserole
Let it rest before slicing. Allowing it to sit for 5–10 minutes after baking makes it easier to serve tidy squares that hold together.
Use good-quality corned beef. Deli-sliced corned beef gives that classic Reuben flavor, but you can also use chopped leftovers from a homemade roast.
Drain the sauerkraut well. Squeeze out as much liquid as possible—this keeps the casserole from turning soggy.
Layer evenly. Spreading each layer of rye bread, meat, cheese, and dressing evenly ensures every bite has that perfect Reuben balance.
Add dressing on top before baking. A drizzle of Thousand Island or Russian dressing helps the casserole stay creamy and flavorful.
Substitutions & Swaps
- No crescent rolls? Try using refrigerated pizza dough or puff pastry for a slightly different twist.
- Not a Swiss fan? Swap in provolone or mozzarella.
- Don’t love Thousand Island? Russian dressing works just as well — it’s a classic pairing with Reuben recipes.
- Vegetarian twist: Use plant-based deli slices and dairy-free cheese for a meatless option.
