• Green Bell Peppers: 4 large peppers, halved and deseeded. (You can use red, yellow, or orange for a sweeter profile).
• Sirloin Steak: 1 lb (about 8oz per serving), sliced into thin 1-inch strips. Ribeye or flank steak also work well.
• Mushrooms: 1.5 cups of sliced button or cremini mushrooms.
• Red Bell Pepper: 1/2 pepper, sliced thinly to add color and sweetness to the filling.
• Red Onion: 1 small onion, sliced.
• Mozzarella Cheese: 2 cups, shredded. Provolone is a traditional choice if you prefer a sharper bite.
• Olive Oil: 2 tablespoons, divided.
• Seasoning: Salt and black pepper to taste.

How to Make Philly Cheesesteak Stuffed Peppers

Step 1: Prepare and Pre-bake the Peppers

Preheat your oven to 400°F (200°C). Cut the green bell peppers in half lengthwise and remove the seeds and ribs. Place them on a baking sheet lined with parchment paper. Drizzle with 1 tablespoon of olive oil and season with salt and pepper. Bake for 10 minutes; this ensures the "shells" are tender by the time the filling is ready.

Step 2: Sear the Steak

While the peppers are in the oven, heat the remaining tablespoon of olive oil in a large skillet over medium-high heat. Add your steak strips, seasoning them generously. Sear for about 1 minute per side until browned but not fully overcooked. Remove the steak from the pan and set it aside to rest.

Step 3: Sauté the Vegetable Filling

In the same skillet (don't wash it! those brown bits are flavor), add the mushrooms. Cook for 2 minutes until they release their moisture. Add the sliced red onions and red pepper strips. Sauté for another 3 minutes until the vegetables are tender-crisp.

Step 4: Assemble and Final Bake

Remove the pre-baked peppers from the oven. Divide the seared steak and the sautéed vegetable mixture evenly among the pepper halves. Top each pepper generously with shredded mozzarella cheese. Return the pan to the oven and bake for another 10 minutes, or until the cheese is bubbly and golden brown.

Recipe Variations

• The Protein Swap: If you aren't a fan of steak, this recipe works wonderfully with ground beef, ground turkey, or even thinly sliced chicken breast.
• Vegetarian Option: Skip the meat entirely and double the amount of mushrooms. Portobello mushrooms provide a "meaty" texture that is perfect for this dish.
• Extra Spice: Add a dash of red pepper flakes or sliced jalapeños to the filling if you enjoy a bit of heat.

Frequently Asked Questions

Will the peppers get soggy?

To prevent soggy peppers, the pre-baking step is crucial. It allows some of the moisture to evaporate before you add the filling. Also, ensure your vegetables are sautéed until the liquid has mostly evaporated before stuffing them.

What is the best cheese to use?

While mozzarella provides a great "cheese pull," Provolone is the most authentic choice for a Philly-style flavor. For a more modern twist, try a Monterey Jack or a sharp White Cheddar.

Storage and Reheating Instructions

• To Store: Place leftovers in an airtight container in the refrigerator for up to 4 days.
• To Reheat: For the best texture, reheat in the oven at 350°F for about 10-15 minutes. If you are in a rush, the microwave works for 1-2 minutes, though the pepper may soften significantly.
• To Freeze: You can freeze these peppers for up to 3 months. Wrap them individually in foil and place them in a freezer bag. Thaw in the fridge overnight before reheating.
