Ingredients
6 pepper bell peppers, assorted colors
3 tablespoons olive oil, divided
1 large white onion, thinly sliced
8 ounces cremini mushrooms, stems trimmed and thinly sliced
1 teaspoon salt, divided
3/4 teaspoon freshly ground black pepper, divided
2 pounds sirloin steak, thinly sliced
9 slices provolone cheese
1 tablespoon fresh thyme leaves, for garnish
Instructions
Preheat the oven to 400°F.
Prepare the peppers: Place a pepper on a cutting board so it is laying on its side. Use a knife to slice about a third off the top, from stem to end. Repeat with all other peppers. Use your hands to remove the ribs and seeds inside the pepper and discard them. Leave the stems on. It helps the pepper keep its shape as it cooks.Slice the pepper “lids” into thin strips. You will cook these with the onions and mushrooms.
Bake the peppers: Place the peppers on a baking dish cut side-up and bake for 30 minutes. No oil needed here!
Meanwhile, cook the onions and peppers: In a large skillet or on a griddle over medium heat, heat 2 tablespoons olive oil. Add the reserved sliced peppers, onions, mushrooms, 1/2 teaspoon salt, and 1/2 teaspoon black pepper. Cook, stirring occasionally, until they softened and start to caramelize around the edges, 12 to 15 minutes. Don’t rush them! Transfer the vegetables onto a clean cutting board. You will chop them with the cooked steak later.
Cook the steak: In the same skillet or griddle over medium-high heat, heat the remaining 1 tablespoon olive oil. Add the sliced steak and the remaining 1/2 teaspoon salt and 1/4 teaspoon black pepper. Spread out the steak so it covers as much surface area as possible in a thin layer. If using a skillet, you may have to cook them in batches so that they cook without steaming. Cook for 1 to 2 minutes without stirring. It will cook very quickly. Then, give it a quick stir to finish cooking.
Chop the filling:Transfer the cooked steak onto the cutting board. Use a chef’s knife to roughly chop the steak and the vegetables into small pieces. Right on the cutting board, toss them together with your hands to combine.
Stuff the peppers: Remove the peppers from oven. Keep the oven on. When they are cool enough to handle, carefully fill each pepper half full with the filling. Place a slice of provolone on top of the filling. Top with more filling use it all!—until the pepper is full.Halve the remaining 3 slices of cheese and top each pepper with them. Sprinkle the tops with thyme.
Bake the stuffed peppers:Bake the stuffed peppers for 15 minutes until the cheese is melted and the peppers are tender. Serve warm.Leftovers can be kept in the fridge for 3 to 4 days tightly covered. Reheat them in a 350°F oven until warmed through, 15 to 20 minutes.

How to Make Philly Cheesesteak Stuffed Peppers Step-by-Step
-Preheat your oven to 400°F so it is ready for roasting the peppers.
-Prepare the bell peppers by slicing about one third off the top of each pepper while it lies on its side. Remove the seeds and ribs while keeping the stems intact so the peppers maintain their shape during baking.
-Slice the pepper tops into thin strips and set them aside. These will cook with the onions and mushrooms later.
-Arrange the hollow peppers cut-side up in a baking dish and place them in the oven. Bake them for about 30 minutes so they soften slightly before adding the filling.
-Heat two tablespoons of olive oil in a large skillet over medium heat. Add the sliced onions, mushrooms, reserved pepper strips, salt, and black pepper. Cook them slowly for 12 to 15 minutes until they soften and begin to caramelize.
-Transfer the cooked vegetables to a cutting board.
-In the same skillet, heat the remaining olive oil over medium-high heat and add the sliced steak with the remaining salt and pepper. Spread it out and cook briefly until browned, about one to two minutes.
-Move the steak to the cutting board and chop it together with the vegetables until everything is in small pieces. Mix them well.
-Remove the roasted peppers from the oven. Fill each pepper halfway with the steak mixture, place a slice of provolone on top, then add more filling until full.
-Top each pepper with additional cheese pieces and sprinkle with fresh thyme.
-Bake again for 15 minutes until the cheese melts and the peppers are fully tender.
