Ingredients
Method
- Prep the peppers: Preheat your oven to 375°F (190°C). Slice the tops off the bell peppers, remove seeds and membranes, and trim the bottoms if needed so they stand upright. Place them in a baking dish.
- Par-bake the peppers: Drizzle a little oil inside each pepper and season with a pinch of salt. Bake for 10–12 minutes to soften slightly. This prevents crunchy peppers later.
- Brown the meat: While peppers bake, heat oil in a large skillet over medium-high heat. Add ground beef and cook, breaking it up, until browned and no longer pink. Drain excess fat if needed.
- Sauté aromatics and veggies: Add onion and garlic to the skillet. Cook 2–3 minutes until softened and fragrant. Stir in mushrooms and cauliflower rice. Cook 4–5 minutes to reduce moisture.
- Build the chili base: Add diced tomatoes, tomato paste, beef broth, chili powder, cumin, smoked paprika, cayenne, and oregano. Season with salt and pepper. Stir well to combine.
- Simmer: Let the mixture simmer 8–10 minutes, stirring occasionally, until thickened. You want a hearty, scoopable filling, not watery.
- Taste and adjust: Taste the chili and adjust salt, pepper, and spices. If you want more heat, add a pinch more cayenne or chili powder.
- Stuff the peppers: Spoon the hot chili mixture into each par-baked pepper, packing it down slightly. Fill to just below the rim.
- Top with cheese: Sprinkle cheese evenly over each pepper. Cover the baking dish with foil, tenting it slightly to avoid sticking to the cheese.
- Bake: Bake covered for 15 minutes, then uncover and bake another 10–12 minutes, until peppers are tender and cheese is bubbly and lightly golden.
- Garnish and serve: Let the peppers rest 5 minutes. Top with chopped cilantro or green onions. Add a dollop of sour cream if you like. Serve warm.

Benefits of This Recipe
- Low-carb and keto-friendly: No beans or grains.
Cauliflower rice and peppers keep net carbs low while adding fiber.
- Protein-packed: Ground meat provides steady, satisfying protein to keep you full.
- Vegetable-forward: Bell peppers, onions, mushrooms, tomatoes, and cauliflower add micronutrients and texture.
- Budget-conscious: Uses everyday ingredients, stretches meat with low-cost veggies, and makes great leftovers.
- Customizable heat and flavor: Easy to adapt to mild or spicy preferences without changing the base recipe.
Pitfalls to Watch Out For
- Watery filling: If the chili is too loose, it will sog up the peppers. Simmer until thick, and drain tomatoes well.
- Undercooked peppers: Skip par-baking and you may end up with crunchy peppers. That short pre-bake is worth it.
- Overfilling: Pack too tightly and the peppers can split or overflow.
Leave a little space at the top for cheese.
- Too salty: Tomato paste and broth both add salt. Taste before salting aggressively.
- Stuck foil: If foil touches the cheese, it can stick. Tent the foil or spray the underside lightly with oil.
Recipe Variations
- Turkey or chicken: Swap ground beef for turkey or chicken for a lighter option.
- Chorizo kick: Use half ground beef, half chorizo for smoky heat.
Reduce added salt accordingly.
- No-dairy: Skip the cheese or use dairy-free shreds. Add diced avocado on top after baking for richness.
- Extra veg: Stir in chopped zucchini or spinach; cook down to remove moisture.
- Tex-Mex toppings: Finish with jalapeños, pickled onions, or a squeeze of lime.
- White chili twist: Use ground chicken, green chiles, cumin, oregano, and a little cream cheese for a creamy, mild version.
FAQ
Are stuffed peppers keto?
Yes, as long as the filling stays low-carb. This recipe skips beans and grains, using cauliflower rice and low-sugar tomatoes, so it fits most keto macros.
Do I have to pre-bake the peppers?
Par-baking helps soften the peppers and shortens the final bake time.
It’s the best way to get tender peppers without overcooking the filling.
Can I make the filling ahead of time?
Absolutely. Make the chili up to 3 days in advance and refrigerate, or freeze for up to 2 months. Reheat gently before stuffing for faster bake time.
What color bell peppers are best?
Green peppers are more savory and slightly bitter, while red, yellow, and orange are sweeter.
Any work well, so use your favorite or a mix for color.
How can I make it spicier?
Add diced jalapeños when sautéing the onions, increase cayenne, or top baked peppers with hot sauce or crushed red pepper.
Can I omit the cheese?
Yes. The peppers will still be tasty and satisfying. For richness without dairy, top with avocado or a drizzle of olive oil after baking.
How do I keep the peppers from tipping over?
Trim a tiny slice off the bottom to create a flat base, being careful not to cut a hole.
Nestling them in a snug baking dish also helps them stand upright.
What sides go well with these?
Try a simple green salad, roasted broccoli, or sautéed zucchini. If you’re not strict keto, a small side of cauliflower mash works great too.
