Ingredients for the Baked Chicken Fajitas
  • ▢ 1.5 lbs. chicken breasts (up to 2lbs. chicken will work)
  • ▢ 4 large sweet bell peppers, thinly sliced (any variation of red, yellow, and orange)
  • ▢ 1 yellow onion, thinly sliced
  • ▢ 2 tbsp extra-virgin olive oil
  • ▢ 4 tbsp homemade taco seasoning
  • ▢ 1 tbsp tapioca starch (see notes)
Suggested Ingredients to Go Along with Fajita Bake
  • ▢ brown rice
  • ▢ guacamole
  • ▢ cilantro lime dressing
  • ▢ pico de gallo
  • ▢ mixed greens
  • ▢ black or pinto beans
  • ▢ cilantro
  • ▢ lime wedges

Preheat oven to 400.
Place the sliced peppers and sliced onion in a 9x13 baking dish. Try to push the peppers and onions to the edges of the pan as much as possible to make room for the chicken. Place chicken breasts on the bottom of the dish (if you have some peppers underneath the chicken that's okay).
Drizzle the chicken and veggies with olive oil. Next, mix the seasoning mix and tapioca starch together. Then sprinkle this over the chicken, peppers, and onions. (NOTE: if using store-bought seasoning, you do not need the tapioca starch - just sprinkle directly on chicken/veggies).
Bake for about 25-30 minutes, or until the internal temperature of the chicken is 165 F (see notes). Mix peppers half way through baking time.
Remove chicken breasts from the baking dish and shred with two forks. Place shredded chicken back in dish and mix with the pepper and onions.
  • If your peppers are on the small side, I would use 5 peppers.
  • Tapioca starch is used to thicken the sauce. The peppers will let off a lot of water as they are cooked and this helps to create a nice base for the chicken and peppers. You can sub arrowroot or corn starch in its place. If using store-bought seasoning, you can omit the starch all together.
  • I use roughly 1.5 lbs. of chicken in this recipe. This is typically 2-3 chicken breasts. Total cooking time will vary pending the size of your breasts. If your chicken breasts are on the smaller side and cook quicker than the peppers, you can remove them from the dish and shred. Add back to dish once the peppers are done cooking.

    I’m so glad you posted this recipe. I made it last night and halfway through baking, I opened the oven to stir the peppers, and much to my dismay, the chicken breasts were totally raw. So I baked them longer than the recipe states, and it turned out amazing. I gave a good portion to my son and his wife to have for dinner tonight, and they loved it! Unfortunately, I still don’t have any sense of smell or taste since Covid (2 years and counting), but the texture was very delectable and there was a slight flavor of the spices. I will definitely make this again! Thank you for sharing!!!

      Thanks for letting me know. I love hearing when others are enjoying my recipes. And sorry to hear about your continued loss of taste/smell, but I'm glad you could gather some slight flavor from the spices.
