Ingredients

  • Baton sourdough bread (or good quality sourdough sliced in baton shape)

  • 4-6 ounces thinly sliced rare roast beef (store-bought or homemade)

  • 2 slices sharp cheddar or Swiss cheese (provolone is also a good alternative)

  • 2 tablespoons creamy horseradish sauce or mayonnaise (or a mix of both)

  • 1-2 teaspoons minced garlic (optional, for garlic mayo)

  • Butter (room temperature, about 2 tablespoons)

  • Salt and freshly cracked black pepper to taste

  • Optional toppings: sliced onions, lettuce, tomato slices, cracked pepper, or coleslaw

Horseradish Sauce (Optional)

  • ½ cup sour cream or mayonnaise

  • Prepared horseradish to taste (start with 1-2 tablespoons and adjust)

Mix gently and taste, adding more horseradish if desired.

Instructions

  1. Prepare the Bread: Slice the baton sourdough into sandwich-sized pieces. Lightly butter one side of each slice.

  2. Toast the Bread: Toast the buttered side of the bread slices in a skillet or griddle over medium heat until golden and crisp.

  3. Spread Sauce: Flip the bread and spread a generous layer of horseradish sauce or mayonnaise (or a garlic mayo made by mixing minced garlic into mayo) on the untoasted side. Lightly season with salt and pepper.

  4. Assemble the Sandwich: Place slices of sharp cheddar or Swiss cheese on each slice of bread over the sauce. Layer the thinly sliced roast beef on one slice.

  5. Optional Additions: Add sliced onions, lettuce, or tomato if desired.

  6. Close and Heat (Optional): For a warm, melted sandwich, press the sandwich together and grill it in the skillet, buttered sides out, until the cheese melts and bread is golden brown. You can sprinkle grated Parmesan on the buttered sides before grilling for extra flavor and crunch.

  7. Serve: Slice the sandwich in half and serve immediately.

Notes

  • Using rare roast beef and sharp cheddar with creamy horseradish sauce is a classic combination that balances rich meat flavor with a spicy kick.

  • Garlic mayo adds depth to the flavor and pairs well with the beef and cheese.

  • Toasting the sourdough bread ensures it holds up well to moist ingredients like horseradish sauce or gravy if you choose to add it.

  • Optional toppings like lettuce or coleslaw can add crunch and freshness but are not necessary if you prefer simplicity.
