🔥 How to Make the Perfect Roast Beef Sandwich

Step 1: Prepare the Bread

  1. Butter the bread slices on one side to create a crispy, golden texture.
  2. Toast in a skillet or pan over medium heat until golden brown. Set aside.

Step 2: Warm the Roast Beef (Optional)

  • If using cold deli roast beef, you can keep it cold for a classic sandwich.
  • If you prefer it warm, heat the roast beef briefly in a pan or microwave.

Step 3: Make the Spread

  1. Mix together mayonnaise, horseradish sauce, Dijon mustard, and black pepper in a small bowl.
  2. Spread evenly on one or both slices of toasted bread.

Step 4: Assemble the Sandwich

  1. Layer the roast beef generously on one slice of bread.
  2. Add cheese slices, then place the sandwich under a broiler for 1-2 minutes to melt the cheese (optional).
  3. Top with lettuce, tomato, and caramelized onions if desired.
  4. Close the sandwich with the second slice of bread and slice in half.

Step 5: Serve & Enjoy!

  • Pair with French fries, coleslaw, or a bowl of soup for a complete meal.
  • Serve with extra horseradish sauce or au jus for dipping.
