Health notes
- High protein: Lean ground beef and cheese keep the protein high and the dish filling.
- Low carb: Bell peppers replace tortillas or rice for a low-carb vessel.
- Sugar-free: Use a sugar-free taco seasoning or make your own.
- Vegetable boost: Peppers add fiber, vitamin C, and color.
Key element — pre-cook the peppers slightly
A quick 5–7 minute bake or microwave of the empty pepper halves softens them so they finish tender (not crunchy) at the same time as the filling and cheese.
Ingredients
Peppers & protein
- 3–4 large green bell peppers, halved and seeded
- 1.25–1.5 lb (570–680g) lean ground beef (90% lean or leaner)
- ½ medium onion, diced
- 2 garlic cloves, minced
Seasoning & sauce
- 2–3 Tbsp taco seasoning (sugar-free) or homemade blend
- ½ cup diced tomatoes or sugar-free salsa
- ¼–⅓ cup water or low-sodium broth
- Salt and black pepper to taste
Cheese & toppings
- 1½–2 cups shredded Mexican blend or cheddar cheese
- Fresh cilantro for garnish
- Optional: sour cream, sliced jalapeños, avocado, or green onion
Swaps
- Turkey or chicken: Use lean ground turkey or chicken for a lighter version.
- Colorful peppers: Red, yellow, or orange peppers work just as well and are slightly sweeter.
- Extra cheesy: Mix some cheese into the beef filling before stuffing.
- Spicier: Add diced jalapeños or extra chili powder to the beef.
Instructions
| 1 | Prep the peppers. Preheat oven to 375°F (190°C). Cut the peppers in half lengthwise and remove seeds and membranes. Place cut-side up in a lightly greased baking dish. Bake 5–7 minutes (or microwave 2–3 minutes) to soften slightly. Drain any liquid. |
| 2 | Cook the filling. In a large skillet over medium-high heat, cook the ground beef with the onion until browned and cooked through, about 7–8 minutes. Drain excess fat. Stir in the garlic, taco seasoning, diced tomatoes or salsa, and water or broth. Simmer 2–3 minutes until thickened. Taste and adjust seasoning. |
| 3 | Stuff the peppers. Spoon the beef mixture evenly into the pepper halves, packing it in gently. Top each half generously with shredded cheese. |
| 4 | Bake. Return the dish to the oven and bake 18–22 minutes until the peppers are tender and the cheese is melted and bubbly. For extra browning, broil the last 1–2 minutes while watching closely. |
| 5 | Serve. Let rest 3–5 minutes. Garnish with fresh cilantro and any desired toppings such as sour cream, jalapeños, or avocado. Serve two halves per person. |
Pro tips
- Pre-cooking the pepper halves ensures they finish tender instead of still crunchy.
- Use a leaner ground beef so the filling isn’t greasy.
- Pack the filling firmly but don’t overstuff — leave a little room for the cheese to melt over the edges.
- Make your own taco seasoning to control salt and avoid hidden sugars.
- These reheat very well and make excellent meal-prep lunches.
