Ingredients
(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)
Roast beef – Thinly sliced, tender beef provides the hearty base of the sandwich.
Cheddar cheese – Sharp cheddar adds bold flavor and melts beautifully into the beef.
Bread – Sturdy bread like sourdough, ciabatta, or hoagie rolls hold up well to the fillings and heat.
Butter – Brushed on the bread for golden, crispy edges when toasted.
Onions (optional) – Caramelized onions bring sweetness that balances the savory richness.
Horseradish sauce or mayo – A creamy spread that adds tang and moisture.
Mustard (optional) – Adds a zesty note that cuts through the richness.
Garlic powder or seasoning salt – Sprinkled lightly for extra flavor.
Pickles (optional) – A crunchy, tangy sidekick that complements the sandwich.
Directions
Start by preheating a skillet or griddle over medium heat. Butter one side of each bread slice. On the unbuttered side, spread a thin layer of horseradish sauce or mayo, and mustard if desired.
Layer slices of roast beef and cheddar cheese between the bread slices. If using caramelized onions, add them now for extra flavor. Place the sandwich in the hot skillet, buttered side down, and cook until golden brown and the cheese begins to melt. Flip carefully and cook the other side until equally golden, pressing gently with a spatula to help the melt.
Once the cheese is fully melted and the bread is crisp, remove from the skillet. Slice in half and serve hot, ideally with chips, fries, or a simple green salad.
