01 - Preheat oven to 400°F. Line a baking sheet with parchment paper to prevent sticking and ensure easy cleanup.
02 - Arrange corned beef slices on a clean work surface. Top each slice with one Swiss cheese slice, ensuring complete coverage.
03 - Distribute approximately 2 teaspoons of drained sauerkraut along the center of each prepared slice. Drizzle with a small amount of sugar-free dressing.
04 - Sprinkle caraway seeds and black pepper over the sauerkraut mixture if desired. Roll each slice tightly from one end to the other, creating secure cylinders.
05 - Place rolled portions seam-side down on the prepared baking sheet, ensuring even spacing for proper heat circulation.
06 - Brush the tops of each roll generously with melted butter to promote golden browning and crisp texture.
07 - Bake for 12 to 15 minutes until cheese is fully melted and exteriors are golden with crispy edges. For additional crunch, broil for 1 to 2 minutes at the end of baking time, watching closely to prevent burning.
08 - Allow roll ups to rest for 2 minutes on the baking sheet. Serve warm with additional sugar-free dressing for dipping.
