2 tsp granulated garlic
2 cups low-sodium beef broth
2 tbsp low-sodium tamari
1 tsp Worcestershire sauce
Kosher salt, to taste
Olive oil spray
4 French rolls

directions

Spray a large skillet lightly with olive oil and place over medium heat.

Using tongs, layer the warmed roast beef onto the bottom halves of the rolls. Top with the caramelized onions and slices of provolone.
Bake the sandwiches open-faced for 5 minutes, or until the cheese is melted.
Place the roll tops on the sandwiches and serve hot with individual bowls of strained au jus on the side for dipping.

Variations

Cheese Swap: Use Swiss or mozzarella instead of provolone for a milder or creamier flavor.
Spicy Kick: Add a layer of horseradish sauce or a few sliced banana peppers to the sandwich before baking.
Vegetarian Twist: Substitute mushrooms and vegetable broth for a meatless version.
Garlic Butter Rolls: Brush the rolls with garlic butter before baking for an extra savory touch.
French Bread Alternative: Try using ciabatta rolls or hoagie buns if French rolls are not available.

storage/reheating

To store, keep leftover meat and au jus in separate airtight containers in the refrigerator for up to 3 days. Reheat the beef gently in a skillet with a little broth to avoid drying it out. Sandwiches are best assembled just before eating to maintain texture. Bread can be reheated in the oven until warm and crisp.
