Common Mistakes to Avoid

- Adding too much liquid: Excess liquid can prevent the cheese from browning properly.
- Adding cheese too early: For a golden, bubbly topping, add the cheese during the final stage of baking.
Required Equipment
- 9 × 13-inch baking dish — provides enough room for the chicken and peppers to cook evenly.
- Meat mallet — helps create evenly thick chicken breasts for consistent cooking.
- Small mixing bowl — makes combining the fajita seasoning quick and easy.
- Instant-read thermometer — helps prevent undercooking or overcooking the chicken.
- Sharp chef’s knife — makes slicing peppers and chicken easier and more precise.
Storage Instructions
Allow leftovers to cool promptly before transferring them to airtight glass or BPA-free food containers.
- Refrigerator: Keep for up to 3–4 days.
- Freezer: Freeze individual portions in freezer-safe airtight containers for up to 2–3 months.
- Thawing: Thaw overnight in the refrigerator.
- Reheating: Warm covered in a 325°F (165°C) oven for 10–15 minutes or microwave gently until heated through.
The chicken remains a protein-rich option after storage; avoid repeatedly reheating the entire batch because this can dry out the chicken and cheese.

📝 Ingredients
Chicken & Vegetables
- 1½ lb (680 g) boneless, skinless chicken breasts, 4 pieces
- 1 medium red bell pepper, sliced
- 1 medium yellow bell pepper, sliced
- 1 medium green bell pepper, sliced
- ½ medium yellow onion, thinly sliced
- 3 cloves garlic, minced
- 1 tablespoon extra-virgin olive oil
- 1 tablespoon fresh lime juice
Fajita Seasoning
- 2 teaspoons smoked paprika
- 1½ teaspoons ground cumin
- 1 teaspoon chili powder
- ½ teaspoon dried oregano
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- ½ teaspoon salt
- ¼ teaspoon black pepper
- ¼ teaspoon cayenne pepper, optional
Cheese & Garnish
- 1 cup (about 100 g) shredded part-skim mozzarella cheese
- 2 tablespoons chopped fresh cilantro or parsley
- 1 lime, cut into wedges
Ingredient note: Use reduced-fat mozzarella if you want to lower the calorie content slightly. For a stronger flavor, a small portion of shredded Monterey Jack can replace some of the mozzarella.
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 chicken.
If the breasts are thick, place them between sheets of parchment and gently pound them to approximately ¾-inch thickness. This helps them cook evenly. - Mix the seasoning.
In a small bowl, combine smoked paprika, cumin, chili powder, oregano, garlic powder, onion powder, salt, black pepper, and optional cayenne. - Season the chicken.
Rub the chicken with approximately 2 teaspoons olive oil, then coat both sides evenly with the fajita seasoning. - Prepare the vegetables.
Place the sliced red, yellow, and green peppers and onion into the baking dish. Add minced garlic and the remaining olive oil, then toss everything together. - Arrange the chicken.
Place the seasoned chicken breasts over the vegetables. Drizzle the lime juice over the chicken and peppers. - Bake.
Place the dish in the 400°F oven and bake uncovered for approximately 20–25 minutes. Cooking time depends on the thickness of the chicken. - Add the cheese.
Once the chicken is nearly cooked, sprinkle the shredded mozzarella evenly over each breast. - Finish baking.
Return the dish to the oven for 5–8 minutes, until the cheese is melted and bubbling. For a more golden top, switch to broil/high heat for 1–2 minutes, watching carefully. - Check the chicken.
Insert an instant-read thermometer into the thickest portion. Chicken should reach 165°F (74°C) for food safety. - Rest and garnish.
Remove the dish from the oven and let the chicken rest for 5 minutes. Sprinkle with fresh cilantro or parsley and serve with lime wedges.
High-protein cooking tip: Keep the chicken portion generous and use lean chicken breast as the main protein source. Avoid replacing too much chicken with cheese because cheese adds calories more quickly than protein.
