Why You’ll Love This Recipe

🛒 Ingredients
- 2 cans (8 oz each) refrigerated crescent roll dough (or crescent dough sheets)
- ½ lb (approx. 225g) cooked corned beef, thinly sliced or shredded
- 1 cup sauerkraut, thoroughly drained and pressed dry
- 8 slices Swiss cheese (or 1 ½ cups shredded Swiss)
- ⅓ cup Thousand Island or Russian dressing
- 1 large egg (beaten, for egg wash)
- 1 tsp caraway seeds (optional, for that authentic rye bread flavor)
- Freshly cracked black pepper, to taste
👩🍳 Step-by-Step Instructions
Step 1: Prep the Oven and Base Crust
Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with non-stick cooking spray. Unroll one can of crescent roll dough and press it into the bottom of the prepared dish, pinching the seams together to form a solid, even base layer.
Step 2: Par-Bake the Bottom Crust
Bake the bottom crust on its own for 8 to 10 minutes until it is just slightly set and a very pale golden color.
Pro Tip: Par-baking the bottom crust ensures your casserole stays perfectly flaky and avoids the dreaded soggy bottom from the sauerkraut and dressing!
Step 3: Layer the Reuben Goodness
Remove the crust from the oven. Spread the Thousand Island or Russian dressing evenly over the warm crust. Layer half of the Swiss cheese over the dressing, followed by the entire layer of shredded corned beef.
Step 4: Add the Tang
Evenly scatter the drained sauerkraut over the corned beef, then top with the remaining Swiss cheese and a sprinkle of black pepper. (Make sure to squeeze your sauerkraut in a paper towel beforehand so it doesn’t add excess moisture to the bake!)
Step 5: Top and Bake to Golden Perfection
Unroll the second can of crescent roll dough and place it carefully over the cheese layer to cover the casserole. Brush the top dough lightly with the beaten egg wash and sprinkle with caraway seeds if desired. Bake for 15 to 20 minutes until the top crust is deeply golden-brown and the cheese is bubbly and melted.
Let it cool for about 5 minutes, slice into squares, and serve warm with extra dressing on the side!
💡 Quick Variations to Try
- The Rachel Bake: Swap out the corned beef for deli turkey or pastrami and use coleslaw instead of sauerkraut for a sweeter, milder twist.
- Party Sliders Style: Cut the crescent dough into smaller squares before baking to turn this into a bite-sized appetizer for your next gathering.
