Preheat your oven to 375°F. Grab a 9×13-inch baking dish and give it a quick coat of cooking spray or butter so nothing sticks later.

Pop open one can of crescent dough and press it into the bottom of your dish. Use your fingers to pinch any seams together so you have one solid piece of dough covering the bottom.

Lay 4 slices of Swiss cheese over the dough base. Scatter the corned beef evenly on top of the cheese layer.

Spread the well-drained sauerkraut over the meat. Don't skip patting it dry – nobody wants soggy dough! Drizzle that Thousand Island dressing all over in an even layer.
05 -
Layer on the remaining 4 slices of Swiss cheese. Unroll the second can of crescent dough and carefully place it on top, stretching to cover everything. Press down around the edges to seal it up.

Brush the top with beaten egg – this gives it that beautiful golden color when baked. If you're using caraway seeds, sprinkle them over the top now.
07 -
Slide the dish into your preheated oven and bake for 25-30 minutes, until the top is puffy and golden brown and you can see the filling bubbling around the edges.

Let it sit for about 5 minutes before cutting (trust me, it's worth the wait). Cut into squares and watch it disappear faster than you thought possible.
