High-Protein Mexican Chicken Stuffed Peppers (Low-Carb & Meal Prep)

Savory, spiced lean chicken and melted cheese packed inside sweet, tender bell peppers. This high-protein, low-carb dinner delivers bold Tex-Mex flavor with balanced macros and effortless meal-prep durability.

Why This Recipe Works

Traditional stuffed peppers often rely on heavy white rice fillers that spike carbohydrates and weigh down the dish. By substituting finely riced cauliflower, this recipe slashes excess carbs while keeping the familiar, comforting texture of a hearty grain filling.

Lean ground chicken breast provides a massive protein boost without excess saturated fat. When browned properly with an aromatic blend of chili powder, cumin, and smoked paprika, the meat develops deep, savory notes that pair naturally with fire-roasted tomatoes.

Ingredients

The Stuffed Peppers

• 4 large bell peppers (red, yellow, or orange), cut in half lengthwise, cored, and seeded
• 1 tbsp olive oil
• 1 lb lean ground chicken (93/7 or 99/1)
• 1 small yellow onion, finely diced
• 2 cloves garlic, minced
• 1 cup riced cauliflower (fresh or thawed frozen, excess moisture squeezed out)
• 1/2 cup fire-roasted diced tomatoes, well drained

Seasonings & Toppings

• 1 tbsp chili powder
• 1.5 tsp ground cumin
• 1/2 tsp smoked paprika
• 3/4 tsp kosher salt
• 1/4 tsp black pepper
• 1/2 cup shredded Monterey Jack or sharp cheddar cheese
• 2 tbsp fresh cilantro, chopped (for garnish)

Instructions

1. Preheat the oven to 375°F (190°C). Arrange the prepared bell pepper halves cut-side up in a 9x13-inch baking dish. Lightly mist or brush the outer skins with a touch of olive oil.
2. Pre-bake the peppers for 15 minutes while you prepare the filling. This initial steam-bake softens the tough cell walls of the bell pepper so they hold their shape without becoming soggy later.
3. Brown the meat and aromatics: Heat the olive oil in a large skillet over medium-high heat. Add the diced yellow onion and cook for 3 to 4 minutes until translucent. Add the minced garlic and cook for 30 seconds until fragrant. Add the ground chicken, breaking it apart with a wooden spoon, and cook until completely browned and cooked through (about 6 to 7 minutes).
4. Incorporate the vegetable base: Stir the riced cauliflower and drained fire-roasted tomatoes directly into the skillet with the cooked chicken.
5. Season the mixture: Sprinkle the chili powder, ground cumin, smoked paprika, kosher salt, and black pepper over the skillet contents. Stir thoroughly to distribute the spices evenly, cooking for another 3 to 4 minutes until any excess moisture from the cauliflower evaporates. Remove from heat.
6. Fill the peppers: Spoon the savory chicken and cauliflower mixture evenly into the pre-baked bell pepper halves, pressing down gently to pack each boat full.
7. Bake and melt: Return the baking dish to the 375°F oven and bake for 15 minutes. Sprinkle the shredded Monterey Jack cheese evenly across the top of each stuffed pepper and bake for an additional 3 to 5 minutes, or until the cheese is melted, bubbly, and lightly golden at the edges.
8. Garnish and serve: Remove from the oven, let cool for 5 minutes, garnish with fresh chopped cilantro, and serve warm. If you enjoy meal-prepping vibrant weeknight proteins alongside these peppers, check out our collection of high-protein chili lime chicken bowls.

Cooking Tips & Troubleshooting

• Preventing Watery Peppers: Bell peppers naturally release moisture as they bake. Pre-baking the empty shells for 15 minutes and draining your canned tomatoes thoroughly ensures your baking dish doesn't pool with liquid.
• Cauliflower Moisture: If using frozen riced cauliflower, thaw it completely and squeeze it tightly in a clean kitchen towel to wring out excess water before adding it to the skillet.
• Even Sizing: Try to select bell peppers that are uniform in size so they cook at the exact same rate in the oven.

Storage & Meal Prep

These stuffed peppers are exceptionally meal-prep friendly. Store cooled leftovers in an airtight glass container in the refrigerator for up to 4 days.

To freeze, wrap individual stuffed pepper halves tightly in foil or store in freezer-safe containers for up to 2 months. Thaw overnight in the refrigerator before reheating.

Frequently Asked Questions

Can I use ground turkey instead of ground chicken?

Yes, lean ground turkey (93/7 or 99/1) works wonderfully as a direct 1:1 substitute without altering the cooking time or flavor profile.

Do I have to use cauliflower rice?

If you prefer higher carbohydrates or aren't following a low-carb diet, you can substitute cooked brown rice, quinoa, or black beans in equal measure.

How do I reheat these without making them soggy?

For best texture, reheat in a toaster oven or conventional oven at 350°F for 10-12 minutes until warmed through. The microwave works well too (2 minutes on high), though the pepper will retain a softer texture.

Can I make these dairy-free?

Yes, simply omit the shredded cheese or use your favorite dairy-free plant-based cheese alternative for melting on top.

What kind of bell peppers work best?

Red, yellow, and orange bell peppers are sweeter and less bitter than green bell peppers, making them the ideal choice for this Mexican-inspired flavor profile.
