Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

Chicken breasts
Boneless, skinless chicken breasts form the hearty base of this dish. They bake beautifully under the cheese and vegetables, staying moist thanks to the fajita seasoning and melted cheese on top.

Bell peppers
Sliced red, yellow, or green bell peppers add sweetness, color, and crunch. Their natural juices help keep the chicken tender as everything bakes together.

Onion
Sliced onion lends savory depth and softens into the perfect texture once baked. Red, yellow, or white onions all work well.

Fajita seasoning
This blend provides smoky, warm flavors. Homemade or store-bought seasoning both work. It delivers a balanced mix of cumin, garlic, chili powder, and paprika.

Olive oil
Olive oil helps coat the vegetables and chicken, encouraging even cooking while preventing dryness.

Shredded cheese
Melty cheddar, Monterey Jack, or a Mexican blend creates the irresistible cheesy finish. I’ve also tried adding a bit of pepper jack for a subtle kick.

Salt and pepper
These essential seasonings bring out the natural flavors of the chicken and vegetables while balancing the spice blend.

Lime juice
A quick squeeze of lime brightens the dish and adds fresh acidity that complements the cheesy richness.

Directions

Preheat your oven to 400°F. Lightly grease a baking dish to prevent sticking. Place the chicken breasts in the dish, spacing them evenly. Drizzle with olive oil and season generously with fajita seasoning, salt, and pepper on both sides. Massage the seasoning into the chicken to ensure full coverage.

In a separate bowl, toss the sliced bell peppers and onion with a drizzle of olive oil and a pinch of fajita seasoning. Spread the vegetables evenly over and around the chicken. The vegetables will soften and release flavor as they bake, infusing the chicken beneath.

Cover the baking dish loosely with foil and bake for 20 minutes. Remove the foil, sprinkle shredded cheese generously over each chicken breast, and return the dish to the oven. Bake for an additional 10–15 minutes, or until the chicken is fully cooked and the cheese is melted and bubbling. Finish with a squeeze of fresh lime juice before serving.
