How to Make Cheesy Philly Cheesesteak Stuffed Peppers

Step 1: Prepare the Bell Peppers

Preheat your oven to 375°F (190°C).

Slice each bell pepper in half lengthwise. Remove the seeds and membranes.

Arrange them in a baking dish and bake for about 10 minutes until they begin to soften.

This helps ensure perfectly tender peppers after baking.

Step 2: Cook the Vegetables

Heat olive oil and butter in a large skillet over medium-high heat.

Add:

• Onion
• Mushrooms

Cook for about 8 minutes until caramelized.

Add garlic and cook for another minute.

Transfer vegetables to a plate.

Step 3: Cook the Steak

Using the same skillet, add the sliced steak.

Season with:

• Salt
• Pepper
• Italian seasoning
• Smoked paprika

Cook only 2–3 minutes since thin steak cooks quickly.

Add Worcestershire sauce.

Return onions and mushrooms to the skillet.

Mix everything together.

Step 4: Stuff the Peppers

Fill each pepper generously with the steak mixture.

Top each pepper with:

• Provolone slices
• Mozzarella
• Cheddar (optional)

Don’t be afraid to pile on the cheese.

Step 5: Bake

Cover with foil.

Bake for 20 minutes.

Remove foil.

Bake another 10 minutes until the cheese becomes bubbly and golden.

Broil for 2 minutes if you like crispy browned cheese.

Step 6: Garnish and Serve

Sprinkle with chopped parsley and freshly cracked pepper.

Serve immediately while hot and gooey.

Tips for Perfect Stuffed Peppers

Use Ribeye Steak

Ribeye has beautiful marbling that creates authentic cheesesteak flavor.

Slice Meat Very Thin

Freeze the steak for 20 minutes before slicing.

It becomes much easier to cut paper-thin slices.

Don’t Overcook the Steak

Since it bakes later, cook it only until just browned.

Choose Firm Peppers

Large peppers hold more filling and bake evenly.

Drain Excess Liquid

If mushrooms release too much moisture, drain before stuffing.

Best Cheese Options

Although provolone is traditional, you can also use:

• White American cheese
• Mozzarella
• Monterey Jack
• Pepper Jack
• Mild Cheddar
• Smoked Gouda
• Havarti

Each creates a delicious variation.

Why This Recipe Is Great for Meal Prep

Expert Tips for the Best Flavor

For authentic Philly cheesesteak flavor, cook the onions slowly until they become golden and sweet before adding the mushrooms. A splash of Worcestershire sauce enhances the savory richness of the beef without overpowering the dish. Freshly shredded mozzarella melts more smoothly than pre-shredded cheese, while provolone adds the signature creamy finish that makes every bite taste like a classic cheesesteak. Finish the peppers with a quick broil to create a beautifully browned, bubbly cheese topping that’s both visually appealing and delicious.
