Ingredients

Scale
  • 1 pound sliced corned beef, chopped
  • 1 (16 ounce) can sauerkraut, drained well
  • 1 (8 ounce) can refrigerated crescent roll dough
  • 1 cup Swiss cheese, shredded
  • 1/2 cup Thousand Island dressing
  • 1 tablespoon Dijon mustard
  • 1 teaspoon caraway seeds (optional)
  • 1 tablespoon butter, melted

Instructions

  1. Preheat your oven to 375 degrees Fahrenheit. Lightly grease a 9×13 inch baking dish.
  2. In a medium bowl, combine the chopped corned beef and the well-drained sauerkraut. Mix gently.
  3. In a separate small bowl, whisk together the Thousand Island dressing and Dijon mustard. Pour this dressing mixture over the corned beef and sauerkraut and toss to coat everything evenly.
  4. Unroll the crescent roll dough and press the triangles into the bottom of the prepared baking dish, forming a crust layer. You can pinch the seams together if needed.
  5. Spread the corned beef and sauerkraut mixture evenly over the crescent roll crust.
  6. Sprinkle the shredded Swiss cheese over the top of the meat mixture. Sprinkle with caraway seeds, if using.
  7. Bake for 25 to 30 minutes, or until the cheese is melted and bubbly and the crust edges are golden brown.
  8. Brush the melted butter lightly over the top crust edges during the last 5 minutes of baking for extra color.
  9. Let the casserole rest for 5 minutes before cutting into squares and serving warm.

Notes

  • Make sure you drain the sauerkraut thoroughly; excess liquid will make the bottom crust soggy.
  • For a richer flavor, use rye bread slices instead of crescent rolls for the base layer. Layer the bread slices tightly on the bottom before adding the filling.
  • This dish reheats well, making it good for meal prep leftovers.
