Ingredients
Method
- Prep the peppers: Heat the oven to 400°F (200°C). Halve the bell peppers lengthwise and remove seeds and membranes. Brush the insides lightly with olive oil and sprinkle with a pinch of salt and pepper. Place cut-side up on a baking sheet and pre-bake for 8–10 minutes to soften slightly.
- Sauté the veggies: While the peppers par-bake, heat a large skillet over medium-high heat. Add olive oil and butter. Sauté the onion and the sliced green pepper with 1/2 teaspoon salt and 1/4 teaspoon black pepper until tender and lightly browned, about 8–10 minutes. Stir in the minced garlic for the last 30 seconds. Transfer to a bowl.
- Cook the steak: Increase heat to high. If the pan is dry, add a drizzle of oil. Add the shaved beef in a single layer (work in batches if needed). Season with remaining salt, pepper, smoked paprika, and garlic powder. Sear 1–2 minutes per side until just cooked through. Don’t overcook—it will bake again.
- Add flavor: Return the cooked onions and peppers to the pan with the steak. Stir in the Worcestershire sauce and toss to combine. Taste and adjust seasoning.
- Layer with cheese: Remove the peppers from the oven. Place half a slice of provolone in each pepper half. Spoon the steak mixture evenly into the peppers, then top each with another half to full slice of provolone, depending on how cheesy you like it.
- Bake to melt: Return the stuffed peppers to the oven and bake for 8–12 minutes, until the cheese is melted and lightly golden around the edges.
- Finish and serve: Garnish with chopped parsley if you like. Let them rest for 3–5 minutes so the juices settle, then serve hot.

How to Make It
- Prep the peppers: Heat the oven to 400°F (200°C).
Halve the bell peppers lengthwise and remove seeds and membranes. Brush the insides lightly with olive oil and sprinkle with a pinch of salt and pepper. Place cut-side up on a baking sheet and pre-bake for 8–10 minutes to soften slightly.
- Sauté the veggies: While the peppers par-bake, heat a large skillet over medium-high heat.
Add olive oil and butter. Sauté the onion and the sliced green pepper with 1/2 teaspoon salt and 1/4 teaspoon black pepper until tender and lightly browned, about 8–10 minutes. Stir in the minced garlic for the last 30 seconds.
Transfer to a bowl.
- Cook the steak: Increase heat to high. If the pan is dry, add a drizzle of oil. Add the shaved beef in a single layer (work in batches if needed).
Season with remaining salt, pepper, smoked paprika, and garlic powder. Sear 1–2 minutes per side until just cooked through. Don’t overcook—it will bake again.
- Add flavor: Return the cooked onions and peppers to the pan with the steak.
Stir in the Worcestershire sauce and toss to combine. Taste and adjust seasoning.
- Layer with cheese: Remove the peppers from the oven. Place half a slice of provolone in each pepper half.
Spoon the steak mixture evenly into the peppers, then top each with another half to full slice of provolone, depending on how cheesy you like it.
- Bake to melt: Return the stuffed peppers to the oven and bake for 8–12 minutes, until the cheese is melted and lightly golden around the edges.
- Finish and serve: Garnish with chopped parsley if you like. Let them rest for 3–5 minutes so the juices settle, then serve hot.
Keeping It Fresh
- Fridge: Store cooled stuffed peppers in an airtight container for up to 4 days.
- Reheating: Warm in a 350°F (175°C) oven for 10–15 minutes, or microwave in 45-second bursts until hot. For best texture, the oven is your friend.
- Freezer: Freeze fully cooked and cooled peppers individually wrapped, then bagged, for up to 2 months.
Thaw overnight in the fridge and reheat in the oven.
- Meal prep tip: Keep extra provolone on hand. Add a fresh piece before reheating for that just-melted finish.
Why This is Good for You
- High-quality protein: Lean steak delivers essential amino acids to support muscle repair and keep you full.
- Lower-carb base: Using bell peppers instead of a roll cuts down on refined carbs and bumps up fiber and vitamin C.
- Balanced macros: You get protein from steak and cheese, healthy fats from olive oil, and micronutrients from the veggies.
- Customizable: You can easily tweak sodium, fat, and calories by choosing leaner cuts, lighter cheese, or less oil.
What Not to Do
- Don’t skip pre-baking the peppers: Raw peppers take longer and can release water, which waters down the filling.
- Don’t overcook the steak: Thin-sliced beef cooks fast. If you overdo it, it’ll turn tough and dry.
- Don’t overcrowd the pan: Crowding steams the meat.
Cook in batches for better browning and flavor.
- Don’t forget seasoning: A little salt, pepper, and Worcestershire make the filling taste like a true cheesesteak.
- Don’t drown it in liquid: Extra broth or sauce can make the peppers soggy. Keep moisture controlled.
Recipe Variations
- Mushroom lovers: Add 1 cup sliced cremini mushrooms to the onions and peppers and cook until browned for extra umami.
- Cheese swap: Try provolone, mozzarella, or a combo. For a classic twist, add a little Cheez Whiz on top after baking.
- Lower fat: Use top round or eye of round and reduce cheese to one slice per pepper.
- Dairy-free: Use your favorite dairy-free provolone-style slices or a melty vegan mozzarella.
- Spicy kick: Toss in red pepper flakes or top with pickled jalapeños before serving.
- Ground beef option: Swap steak for 90–93% lean ground beef.
Brown fully, drain if needed, and season as directed.
- Air fryer method: Air fry par-baked stuffed peppers at 360°F (182°C) for 6–8 minutes until cheese is bubbling.
- Extra protein: Stir in diced cooked chicken or add a layer of cottage cheese under the steak for a bigger protein boost.
FAQ
What’s the best cut of beef for this recipe?
Thinly sliced sirloin, flank steak, or shaved beef works best. They cook quickly and stay tender, especially when cut very thin against the grain.
Can I make this ahead?
Yes. Assemble the peppers up to the point of the final bake, cover, and refrigerate for up to 24 hours.
When ready, bake until the cheese is melted and the filling is hot.
Do I need to peel the peppers?
No. The skins help the pepper halves hold their shape. Pre-baking softens them just enough so they’re tender but not floppy.
How do I keep the filling from getting watery?
Cook the onions and peppers until most of their moisture cooks off, and avoid adding extra liquid.
A quick par-bake of the pepper shells helps too.
What cheese melts the best?
Provolone is classic and melts evenly. Mozzarella gives great stretch, and Monterey Jack is a mild, melty alternative. Choose what you enjoy most.
Could I use chicken or turkey instead?
Absolutely.
Thinly sliced chicken breast or turkey works well. Cook it just until done and season as you would the beef.
Is this gluten-free?
Yes, as long as your Worcestershire sauce and cheese are certified gluten-free. Always check labels to be safe.
How can I add more veggies?
Stir in mushrooms, spinach, or thinly sliced zucchini with the onions and peppers.
Sauté until any extra moisture cooks off before stuffing.
What side dishes go well with these stuffed peppers?
Try a simple green salad, roasted potatoes, sweet potato wedges, or cauliflower rice. Keep it light and let the peppers shine.
How do I slice the steak thin enough?
Partially freeze the beef for 20–30 minutes, then slice against the grain with a sharp knife. Or buy pre-shaved beef if available.
