- Overbaking the chicken — Check the thickest piece with a thermometer and remove it once it reaches 165°F (74°C).

- Small mixing bowl — Makes combining the fajita seasoning quick and easy.
- Sharp chef’s knife — Creates evenly sliced peppers and onions for consistent cooking.

- Meat thermometer — Helps prevent overcooking while confirming the chicken reaches a safe temperature.
- Measuring spoons — Keep the spice blend balanced and flavorful.
Storage Instructions
Allow leftovers to cool before transferring them to airtight containers. Refrigerate for up to 3–4 days.
For longer storage, place individual portions in freezer-safe containers or wrap them tightly before freezing for up to 2–3 months.
To reheat, thaw frozen portions overnight in the refrigerator. Warm in a 350°F (175°C) oven for 10–15 minutes or microwave until heated through. Covering the chicken while reheating helps retain moisture.

📝 Ingredients
Chicken
- 4 boneless, skinless chicken breasts, approximately 6 oz (170 g) each
- 1 tablespoon extra-virgin olive oil
- 1½ teaspoons chili powder
- 1 teaspoon smoked paprika
- 1 teaspoon ground cumin
- 1 teaspoon garlic powder
- ½ teaspoon onion powder
- ½ teaspoon dried oregano
- ½ teaspoon salt
- ¼ teaspoon black pepper
- ¼ teaspoon cayenne pepper, optional
Vegetables & Cheese
- 1 medium red bell pepper, sliced
- 1 medium yellow bell pepper, sliced
- 1 medium green bell pepper, sliced
- ½ medium red onion, thinly sliced
- 3 cloves garlic, minced
- 1 cup (100 g) shredded part-skim mozzarella cheese
- 2 tablespoons fresh cilantro, chopped, optional
- 1 tablespoon fresh lime juice, optional
Ingredient notes:
Use fresh bell peppers for the best texture. Part-skim mozzarella keeps the dish cheesy while providing a little more protein with less fat than some full-fat cheese options.
Directions
- Preheat the oven
Heat the oven to 400°F (200°C). Lightly grease a 9×13-inch baking dish with a small amount of olive oil. - Prepare the fajita seasoning
In a small bowl, combine chili powder, smoked paprika, cumin, garlic powder, onion powder, oregano, salt, black pepper, and optional cayenne.
Mix thoroughly so the spices are evenly distributed. - Season the chicken
Pat the chicken breasts dry and rub them with olive oil. Coat both sides generously with the fajita seasoning.
Make sure the thickest areas receive enough seasoning for maximum flavor. - Prepare the vegetables
Add the sliced bell peppers, onion, and minced garlic to the baking dish. Toss with a small amount of the remaining seasoning.
Spread the vegetables into an even layer. - Add the chicken
Place the seasoned chicken breasts over the vegetables.
Leave a little space between each piece so hot air can circulate around the chicken. - Bake
Bake at 400°F (200°C) for approximately 20–25 minutes.
The vegetables should become tender and the chicken should be nearly cooked through. - Add the cheese
Remove the baking dish and sprinkle mozzarella evenly over the chicken and vegetables.
Return to the oven for 5–7 minutes, until the cheese is melted, bubbling, and lightly golden. - Check doneness
Insert a meat thermometer into the thickest part of the largest chicken breast.
The chicken should reach 165°F (74°C). - Rest and finish
Remove from the oven and let the chicken rest for 5 minutes.
Finish with fresh cilantro and a squeeze of lime juice if desired. - Serve
Slice the chicken and spoon the roasted peppers, onions, and melted cheese over each portion.
Serve immediately with your favorite low-carb side.
High-protein cooking tip: Keep the chicken portions similar in size and avoid overcooking them. This helps preserve moisture and ensures you get the full benefit of the approximately 45g protein target per serving.
