These burgers swap the bun for halved bell peppers, which you fill with seasoned 80/20 beef patties and bake until the cheese melts and the peppers soften just enough to hold everything together. It’s a genuinely satisfying dinner that happens to be low-carb, and it comes together in one baking dish with almost no cleanup.
Why this recipe works
The key move here is baking the patties inside the pepper halves rather than cooking them separately. The pepper walls trap steam around the meat, which keeps the patties from drying out in the oven — no need to babyseat them on a skillet. The second thing that matters is fat content: 80/20 ground beef has enough fat to stay juicy at the 160°F internal temperature you need to hit. Leaner blends work but they’ll give you a drier result, so if you go that route, add a tablespoon of olive oil directly into the meat mix before forming the patties.
Shopping notes
- Bell peppers: Buy the widest, flattest peppers you can find — they sit more stably in the pan and give you a bigger surface for the patty. Tall, narrow peppers tip over and spill. Red, orange, and yellow are sweeter and soften more evenly than green.
- Smoked paprika: Regular paprika won’t give you the same depth. Smoked is worth keeping on hand; a little goes a long way and the jar lasts.
- Aioli: Store-bought garlic aioli works fine here. If you’re subbing in regular mayo, stir in a small clove of grated garlic and a squeeze of lemon — it takes 30 seconds and gets you close enough.
- Ground turkey swap: If you use ground turkey instead of beef, cook to 165°F internal — don’t pull it early even if it looks done.
Leftovers and meal prep
Cooked stuffed peppers keep well in an airtight container in the fridge for up to 3 days. Reheat in the same baking dish at 350°F for about 12 minutes — this keeps the pepper from turning soggy, which is exactly what the microwave will do to it. For meal prep, you can form the raw patties and press them into the raw pepper halves up to 24 hours ahead; cover tightly with plastic wrap and refrigerate, then bake straight from the fridge, adding 4–5 minutes to the cook time. Freezing the assembled and cooked peppers is possible but the texture of the pepper degrades noticeably after thawing, so it’s better to freeze just the cooked patties on their own and use fresh peppers when you reheat.
Common problems and fixes
- Peppers tip over in the pan: Trim a very thin slice off the rounded bottom of each pepper half to create a flat base. Don’t cut through — just shave enough to stabilize it.
- Watery liquid pooling in the pan: Peppers release a lot of moisture as they bake. Tilt the pan slightly when you pull it out and spoon off the liquid before serving, or the bottom of the patty sits in it and gets waterlogged.
- Patty shrinks away from the pepper walls: This is normal — beef contracts as it cooks. Press the raw patty firmly into the pepper and slightly up the sides before baking so there’s contact throughout cooking.
- Cheese burns before the beef is done: Add the cheese in the last 4–5 minutes only. Skip the egg in the mix — it makes the patty mushy and doesn’t help the cheese situation either.
- Peppers still too crunchy: If you like a softer pepper, give the halves a 5-minute head start in the oven before adding the raw patties. They’ll be noticeably more tender by the time the beef is cooked through.
Stuffed Bell Pepper Hamburgers
Ingredients
- 1 pound ground beef (80/20 blend) look for grass-fed for richer flavor
- 4 whole bell peppers assorted colors; large & firm, tops and seeds removed, cut in half lengthwise
- 1 teaspoon kosher salt
- ½ teaspoon freshly ground black pepper
- 1 teaspoon smoked paprika optional but adds a smoky depth
- 1 teaspoon garlic powder
- 1 tablespoon olive oil for brushing peppers
- ½ cup shredded cheddar cheese or cheese of choice like provolone or gouda
- ¼ cup diced red onion adds sweetness and crunch
- 4 slices tomato beefsteak or heirloom preferred, thinly sliced
- ¼ cup mayonnaise or aioli optional for serving
Instructions
- Preheat the oven to 400°F (200°C). Line a baking sheet with parchment paper or foil.
- In a large mixing bowl, combine ground beef, salt, black pepper, paprika, and garlic powder. Mix gently with your hands until just combined to avoid overworking the meat.
- Divide the beef mixture into four equal portions and form into patties approximating the size of your halved bell peppers. Slightly flatten the center of each patty to ensure even cooking.
- Lightly brush the bell pepper halves with olive oil. Place them cut side up on the prepared baking sheet.
- Place each patty into a bell pepper half, gently pressing them in. Top with a sprinkle of cheddar cheese and diced red onions.
- Bake for 20 minutes or until the beef is cooked through (internal temperature reaches 160°F/71°C) and the cheese is bubbly and slightly golden.
- Remove from oven and rest for 5 minutes. Garnish with tomato slices and drizzle with mayonnaise or aioli before serving.
Notes
- Try using ground turkey or plant-based meat for a lighter or vegetarian version.
- You can grill the filled bell peppers over indirect heat for a smoky alternative.
- Adding fresh herbs like parsley or cilantro on top boosts aroma and freshness.

Your questions, answered
Can I make these on the grill instead of in the oven?
Yes — cook them over indirect heat with the lid closed, which mimics the oven environment and prevents the peppers from charring before the beef reaches 160°F internal. Direct heat works but you’ll need to watch them closely and rotate the peppers so the bottoms don’t scorch.
How do I keep the patties from falling apart inside the pepper?
Keep the mix cold right up until you form the patties and press them in — warm meat is stickier and looser. You don’t need a binder like egg or breadcrumbs; well-chilled 80/20 beef holds its shape on its own through the bake.
What size pepper works best — large or medium?
Large peppers are the right call here because a standard burger-sized patty needs room to sit flush without bulging over the edges. Medium peppers tend to be too narrow and the patty ends up mounded on top, which means uneven cooking.
