Equipment

  • 9×13 Baking Dish
  • Mixing bowl
  • Oven
  • Meat thermometer

Ingredients
  

For the Chicken

  • 4 medium chicken breasts boneless, skinless
  • 2 tablespoons olive oil
  • 2 tablespoons fajita seasoning

For the Vegetables

  • 1 large red bell pepper sliced
  • 1 large green bell pepper sliced
  • 1 medium onion sliced

For the Cheese

  • 1 1/2 cups Mexican cheese blend shredded

Instructions
 

  • Preheat oven to 375°F. No need to grease the baking dish, as the chicken and veggies will release moisture while cooking.
  • Drizzle chicken breasts with olive oil and rub fajita seasoning all over to coat evenly.
  • Arrange the chicken in the center of the baking dish, leaving space around the edges.
  • Scatter sliced bell peppers and onions around the chicken. Toss them with a little olive oil and extra fajita seasoning for more flavor.
  • Bake for 25 minutes, or until the chicken is almost fully cooked and the veggies start to soften.
  • Sprinkle shredded cheese over the chicken and veggies, then return to the oven for another 5-7 minutes until the cheese is melted and bubbly.
  • Let the dish rest for 5 minutes before serving. This helps the juices redistribute and keeps everything moist.

Notes

For extra flavor, marinate the chicken in the seasoning and olive oil for up to 4 hours before baking. Use a meat thermometer to check doneness – remove at 160°F and let it rest to reach 165°F.
