Ingredients

• 8 oz sliced roast beef
• 1 loaf French bread loaf (or similar crusty bread)
• 2 tbsp butter
• 1 large yellow onion
• 1 tbsp olive oil
• 4 slices provolone cheese
• 4 tbsp mayonnaise
• 2 tsp stone-ground mustard
• 0.5 tsp garlic powder
• 0.5 tsp black pepper
• 2 tbsp fresh parsley (for garnish, optional)

Directions

Step 1

Preheat your oven's broiler to high and position a rack about 6 inches below the heat source.

Step 2

Slice the French bread loaf into 4 equal halves lengthwise to create 4 open-faced sandwich bases.

Step 3

Spread softened butter over the cut sides of the bread halves and place them on a baking sheet, cut-side up.

Step 4

Thinly slice the yellow onion. Heat 1 tablespoon of olive oil in a skillet over medium heat, and sauté the onions until soft and lightly caramelized, about 8 minutes. Set aside.

Step 5

In a small bowl, mix the mayonnaise, stone-ground mustard, garlic powder, and black pepper until combined. Spread an even layer of the mixture onto each buttered bread half.

Step 6

Layer 2 ounces of roast beef slices onto each bread half, slightly overlapping the slices for even coverage.

Step 7

Top each sandwich with a generous portion of the caramelized onions, followed by one slice of provolone cheese per sandwich.

Step 8

Place the baking sheet under the broiler and cook for 3-4 minutes, or until the cheese is fully melted and bubbly. Keep a close eye to avoid burning.

Step 9

Remove the sandwiches from the oven and garnish with chopped fresh parsley if desired.

Step 10

Serve immediately while hot and enjoy these delicious broiled roast beef sandwiches!
