Step 1

Preheat your oven to 375°F (190°C).

Step 2

Line a baking sheet with parchment paper or lightly grease it.

Step 3

Unroll the crescent roll dough onto the prepared baking sheet. Press the perforations together to seal and form a rectangle.

Step 4

Spread the Thousand Island dressing over the dough, leaving a small border around the edges. Layer the corned beef slices on top of the dressing. Evenly distribute the sauerkraut over the corned beef. Sprinkle the shredded Swiss cheese on top.

Step 5

Starting from one long side, roll up the dough tightly, like a jelly roll. Pinch the ends to seal. Position the roll seam-side down on the baking sheet.

Step 6

Lightly brush the top of the roll with the beaten egg white. If desired, sprinkle with caraway seeds.

Step 7

Place the baking sheet in the preheated oven and bake for 20-25 minutes, or until the top is golden brown and the cheese has melted.

Step 8

Remove from the oven and let it cool for a few minutes. Slice into pieces and serve warm.
