Ingredients:
1 tablespoon oil
1 onion, diced
1 green bell pepper, diced
8 ounces mushrooms, diced
2 cloves garlic, chopped
2 pounds ground beef
1/2 teaspoon salt
1/2 teaspoon pepper
1/2 cup cheese whiz (optional)
1 teaspoon Worcestershire sauce
2 tablespoons ketchup
2 eggs
1 cup panko breadcrumbs (gluten-free for gluten-free option)
4 ounces provolone cheese (optional)
8 slices provolone cheese
Instructions:
In a big pan, warm the oil over medium heat. Add the diced onion, bell pepper, and mushrooms. Cook until tender, about 7-10 minutes.
Add the chopped garlic and heat for one minute, or until fragrant. Remove from heat.
In a large mixing bowl, combine the ground beef, salt, pepper, cheese whiz (if using), Worcestershire sauce, ketchup, eggs, breadcrumbs, and the cooked mixture of onions, peppers, mushrooms, and garlic.
Half of the beef mixture should be put into a loaf pan. Place a solid piece of provolone cheese in the middle. Top with the remaining meat mixture and seal the edges well.After shaping the loaf to your liking, put it on a baking pan.
Bake in a preheated 350°F (180°C) oven for about 50-60 minutes, or until the meatloaf is cooked through.
Spread the sliced provolone cheese over the top of the meatloaf. Return it to the oven and broil until the cheese has melted and is slightly bubbly, about 2-4 minutes.
Take it out of the oven and give it some time to settle before slicing.
Serve the Philly Cheesesteak Meatloaf warm and enjoy!
