Step 1

Preheat oven to 200 degrees. Prepare a rimmed baking sheet with a wire rack.

Step 2

On a flat surface, lay out 4 slices of bread.

Step 3

Spread 1 tablespoon of thousand island dressing on each piece. Layer one piece of Swiss cheese, 1/3 cup sauerkraut, 1 more tablespoon dressing, 6 ounces corned beef, one more slice Swiss cheese, and 1 additional tablespoon of dressing.

Step 4

Top each sandwich with another slice of bread and press each sandwich down gently.

Step 5

Brush the tops of two sandwiches with melted butter. Lay them butter-side down in a large skillet. Place a Dutch oven or large pot onto the tops of the sandwiches and cook over medium-low heat until crisp and golden, about 5 minutes.

Step 6

Remove the pot and brush the tops with melted butter. Gently flip over sandwiches. Place pot back on top of sandwiches and cook until the bottom side is crisp, about 5 minutes. Transfer the sandwiches to the prepared baking sheet and place in the oven to keep warm. Repeat the process with remaining two sandwiches.
