Philly Cheesesteak Stuffed Peppers combine tender bell peppers with thinly sliced beef, sautéed onions, and melted provolone for a hearty, low-carb twist on the classic sandwich.
4 large green bell peppers, halved and seeded
1 pound thinly sliced ribeye or shaved beef
1 medium yellow onion, thinly sliced
1 cup sliced mushrooms, optional
1 tablespoon olive oil
1 teaspoon salt
1/2 teaspoon freshly ground black pepper
6 to 8 slices provolone cheese
Preheat oven to 375°F and lightly grease a baking dish.
Arrange halved and seeded peppers cut side up in the dish.
Heat olive oil in a skillet over medium heat. Add onions and cook until soft, about 5 to 7 minutes.
Add mushrooms if using and cook until tender.
Increase heat slightly and add sliced beef. Cook just until no longer pink, about 3 to 4 minutes. Season with salt and pepper.
Spoon beef mixture evenly into each pepper half.
Cover dish with foil and bake for 25 minutes.
Remove foil, top each pepper with provolone, and bake uncovered for 10 to 15 minutes until cheese is melted and lightly golden.
Let rest for a few minutes before serving.
