To create this delicious Mushroom French Dip, gather:

For the Sandwich

  • 4 hoagie rolls or French bread rolls
  • 2 cups mushrooms, sliced (button, cremini, or your favorite variety)
  • 1 cup Swiss cheese, shredded
  • 2 tablespoons butter
  • 1 tablespoon olive oil
  • 1 tablespoon fresh thyme leaves

For the Au Jus

  • 2 cups beef broth
  • 1/4 cup onion, finely chopped
  • 2 cloves garlic, minced
  • 1 tablespoon Worcestershire sauce

Sautéing Mushrooms

In a skillet, heat the butter and olive oil over medium heat. Add the sliced mushrooms and sauté until they are golden brown and tender. Season with fresh thyme leaves, salt, and black pepper. Remove the mushrooms from the skillet and set them aside.

Preparing Au Jus

In a saucepan, combine the beef broth, finely chopped onion, minced garlic, Worcestershire sauce, salt, and black pepper. Bring the mixture to a simmer and let it cook for about 10 minutes to allow the flavors to meld.

Assembling the Sandwiches

Preheat your oven’s broiler.

Slicing Rolls and Adding Cheese

Slice the hoagie rolls or French bread rolls in half lengthwise. On one side of each roll, place a generous layer of shredded Swiss cheese.

Sautéed Mushrooms

Divide the sautéed mushrooms evenly among the rolls, placing them on top of the cheese.

Broiling the Sandwiches

Place the rolls on a baking sheet and broil them in the oven until the cheese is melted and bubbly, and the bread is toasted.

Completing the Sandwiches

Once the cheese is melted and the rolls are toasted, remove them from the oven.

Serving with Au Jus

Serve the Mushroom French Dip sandwiches with bowls of the prepared au jus for dipping.
