📋 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

🥣 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!
