Ingredients:
- 1/2 cup mayonnaise
- 2 tablespoons ketchup
- 1 tablespoon prepared horseradish
- 1 tablespoon sweet pickle relish, drained
- 1 teaspoon Worcestershire sauce
- 1/4 teaspoon smoked paprika
- Pinch of cayenne pepper (optional)
- 4 slices sourdough bread, about 1/2 inch thick
- 4 tablespoons unsalted butter, softened
- 4 ounces thinly sliced corned beef
- 2 ounces Gruyere cheese, thinly sliced
- 2 ounces Swiss cheese, thinly sliced
- 1/4 cup sauerkraut, squeezed dry
- 2 tablespoons Russian dressing
Instructions:
- Make the Russian Dressing: In a small bowl, combine mayonnaise, ketchup, horseradish, pickle relish, Worcestershire sauce, smoked paprika, and cayenne pepper (if using). Stir until well combined. Taste and adjust seasonings to your liking.
- Prepare the Bread: Lightly butter one side of each slice of sourdough bread.
- Assemble the Sandwiches: Place two slices of bread, butter-side down, on a clean surface.
- Layer the Cheese: On each slice of bread, layer half of the Gruyere cheese, followed by half of the Swiss cheese.
- Add the Corned Beef: Top the cheese with half of the corned beef on each sandwich.
- Add the Sauerkraut and Dressing: Spread half of the squeezed-dry sauerkraut over the corned beef on each sandwich. Top with a tablespoon of the prepared Russian dressing on each sandwich.
- Top with Bread: Place the remaining slices of bread, butter-side up, on top of the filling.
- Cook the Sandwiches: Heat a large skillet or griddle over medium heat.
- Grill Until Golden Brown: Place the sandwiches in the hot skillet and cook for 5-6 minutes per side, or until golden brown and the cheese is melted and gooey. Press down gently with a spatula while cooking to ensure even browning.
- Rest and Serve: Remove the sandwiches from the skillet and let rest for a minute or two before slicing in half and serving.
