Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or lightly grease a loaf pan.
Sauté Vegetables:
In a skillet, heat a little olive oil over medium heat. Add the chopped onion, bell pepper, and mushrooms (if using). Sauté until the vegetables are softened, about 5-7 minutes. Remove from heat and let cool slightly.
Mix the Meatloaf:
In a large bowl, combine the ground beef, sautéed vegetables, breadcrumbs, milk, ketchup, egg, garlic powder, Worcestershire sauce, salt, and pepper. Mix until just combined; do not overmix.
Shape the Meatloaf:
Transfer the mixture to the prepared baking sheet or loaf pan. Shape it into a loaf. Make a small indentation along the center of the loaf to help it cook evenly.
Add Cheese:
Bake the meatloaf for about 30-35 minutes. Carefully remove from the oven, sprinkle the shredded cheese on top, and return to the oven for an additional 10-15 minutes, or until the internal temperature reaches 160°F (70°C) and the cheese is melted and bubbly.
Let it Rest:
Remove the meatloaf from the oven and let it rest for 10 minutes before slicing. This helps retain the juices.
Serve:
Slice the meatloaf and serve with your favorite sides. Enjoy your Philly Cheesesteak Meatloaf!
Tips
Serve with additional cheese sauce or ketchup on the side for dipping!
