Ingredients

Ingredient Quantity Notes
Refrigerated crescent roll dough 2 cans (8 oz each; 16 triangles) Serves as both the crust and top layer
Corned beef, chopped or shredded 2 cups Deli meat works perfectly
Sauerkraut, thoroughly drained 2 cups Pat dry to prevent soggy dough
Swiss cheese, shredded 1 ½ cups Melts beautifully
Russian dressing (or Thousand Island) ¾ cup Full-fat provides best texture
Dijon mustard 2 tbsp Optional, adds authentic Reuben flavor
Caraway seeds 1 tbsp Optional, enhances classic taste

Instructions

Step 1: Prepare the Filling
In a large bowl, combine the corned beef, drained sauerkraut, Swiss cheese, Russian dressing, Dijon mustard, and caraway seeds if using. Mix thoroughly so every ingredient is evenly coated.

Step 2: Assemble the Casserole
Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish. Unroll the crescent dough and separate into 16 triangles. Press 8 triangles firmly into the bottom of the dish to form a crust. Spread the prepared filling evenly over this base. Arrange the remaining 8 triangles on top, sealing the edges or leaving them slightly open for a rustic appearance.

Step 3: Bake
Bake the casserole for 25–30 minutes, until the crescents are puffed and golden brown. Let it rest for 5–10 minutes before slicing to allow the filling to set.

Tips for the Best Crescent Reuben Bake

  • Use full-fat Russian dressing; lower-fat versions may thin the filling.
  • Chop the corned beef finely for neater slices.
  • Press the bottom layer of crescent dough well to prevent leakage.
  • Make ahead: Assemble and refrigerate up to 4 hours; add 5 extra minutes to baking time.
  • For a heartier version, double the filling for an extra-loaded casserole.
