Instructions
1
In a large skillet, heat the olive oil over medium heat. Add the sliced mushrooms and sauté until they become tender and golden brown, about 5-7 minutes. Season them with garlic powder, McCormick garlic and herb seasoning, salt, and pepper while they cook.
2
Once the mushrooms are ready, pour in 32 ounces of beef broth (reserving 1/2 cup), along with the Worcestershire sauce and minced onion. Stir to combine.
3
In a small bowl, whisk together the reserved 1/2 cup of beef broth and cornstarch until smooth. Add this mixture to the skillet with the mushrooms and broth, bringing it to a boil. Reduce the heat and let it simmer for about 5 minutes until it thickens slightly.
4
Gently stir in the thinly sliced roast beef into the mushroom au jus and cover the skillet. Allow it to simmer on low heat for an additional 10 minutes to let the beef absorb the flavors.
5
While the beef is simmering, slice the Italian bread into 8 pieces. If the bread is not already cut sandwich-style, split them to create 16 slices.
6
Preheat your oven's broiler. Place the bread slices on a cookie sheet. On the bottom slice of each sandwich, layer approximately 4 or 5 pieces of roast beef, then evenly distribute the sautéed mushrooms. Top each sandwich with a slice of Swiss cheese.
7
Broil the sandwiches in the oven for about 5 minutes or until the cheese is melted and bubbly and the bread is slightly toasted.
8
Serve the sandwiches immediately with a side of the hearty mushroom au jus for dipping. Enjoy every delicious bite!
