Why you’ll love these stuffed peppers
- 32g protein per serving (2 halves) — a proper dinner
- Only 8g net carbs and 380 calories per serving
- Full taco flavour with no shells, wraps or rice
- Melty cheese over every pepper, just like the photo
- Ready in 45 minutes — mostly oven time
- Meal-prep and freezer friendly
Health notes
- Lean beef: High-protein filling — drain well to keep it light.
- Cauliflower rice: Bulks out the filling like rice, for a fraction of the carbs.
- Bell peppers: Vitamin C-rich edible bowls that hold everything together.
- Sugar-free taco seasoning: Check the packet — many hide sugar and fillers.
- Cheese: Measured on top, so every bite tastes cheesy without overdoing it.
Key element — pre-bake the pepper shells
Give the empty pepper halves 10 minutes in the oven while the beef cooks. They soften just enough to be tender at the table — skip it and the peppers stay raw-crunchy while the filling overcooks waiting for them.
Ingredients
Peppers & filling
- 4 large green bell peppers, halved lengthwise and deseeded
- 1 lb lean ground beef (or ground turkey)
- 1 small onion, finely diced
- 2 cloves garlic, minced
- 2 Tbsp sugar-free taco seasoning
- 1 cup cauliflower rice
- ½ cup sugar-free salsa or diced tomatoes
- 1½ cups shredded Mexican-blend cheese, divided
- Salt and pepper to taste
- Fresh cilantro, chopped, for serving
Swaps
- Turkey or chicken: Ground turkey keeps the protein high and the calories lower.
- Any peppers: Red, yellow and orange peppers are sweeter — and slightly higher in carbs.
- No cauliflower rice: Leave it out for an even meatier filling, or add diced zucchini.
- Dairy-free: Skip the cheese and top with guacamole after baking.
Instructions
| 1 | Heat and prep. Heat the oven to 375°F. Halve the peppers lengthwise, remove the seeds, and sit them cut-side up in a baking dish. |
| 2 | Pre-bake the shells. Bake the empty pepper halves for 10 minutes while you make the filling. Drain any liquid that pools in them. |
| 3 | Brown the beef. In a large skillet over medium-high heat, brown the beef with the onion for 6–8 minutes, breaking it up. Drain the fat, then stir in the garlic for 30 seconds. |
| 4 | Season the filling. Stir in the taco seasoning, cauliflower rice and salsa. Simmer 4–5 minutes until the cauliflower rice is tender and the mixture is thick, not watery. |
| 5 | Fill and top. Spoon the filling generously into the pepper halves. Top each with the shredded cheese. |
| 6 | Bake and serve. Bake 15–20 minutes until the cheese is melted and bubbling and the peppers are tender. Scatter with cilantro and serve 2 halves per person, like the photo. |
Pro tips
- Pre-bake the shells — tender peppers, perfectly timed filling.
- Simmer the filling until thick; watery filling makes soggy peppers.
- Pick peppers that sit flat, or trim a thin slice off the bottom so they stand.
- Drain the beef well — it’s the difference between rich and greasy.
- Leftovers reheat brilliantly — these are meal-prep gold.
