Ingredients

  • •4 slices sourdough bread
  • •8 oz thinly sliced roast beef
  • •4 slices sharp cheddar cheese
  • •1 medium onion, sliced
  • •3 tablespoons butter, divided
  • •3 tablespoons mayonnaise
  • •1 tablespoon prepared horseradish
  • •1 teaspoon salt and pepper
  • •2 tablespoons beef broth

Directions

  1. 1Heat 1 tablespoon butter in a skillet over medium heat and cook sliced onions with salt and pepper for 8-10 minutes until golden and caramelized, adding beef broth halfway through.
  2. 2Mix mayonnaise with horseradish in a small bowl and spread on two slices of bread.
  3. 3Layer roast beef, caramelized onions, and cheddar cheese on the horseradish-mayo spread, then top with remaining bread slices.
  4. 4Heat a panini press or skillet over medium heat and butter the outside of each sandwich generously.
  5. 5Cook each panini for 3-4 minutes per side until the bread is golden and the cheese is melted, pressing gently if using a skillet.
  6. 6Remove from heat and let cool for 1 minute, then slice diagonally and serve immediately.

💡 Caramelized onion should be cooked before the panini is assembled; the sandwich grill can melt cheddar but cannot properly soften raw onion.
