Equipment

Ingredients

2 pounds boneless, skinless chicken breasts (about 3-4 pieces)
3 bell peppers (various colors)
1/2 large red onion
2 tablespoons oil (canola, vegetable, extra-virgin olive oil)
1 packet chicken taco seasoning
1 tablespoon freshly squeezed lime juice (from 1 lime)
3 tablespoons chopped cilantro

Instructions

Preheat oven to 400° F. Prepare a sheet pan with rimmed sides on it (12"x17"), by lining it with parchment paper or foil for easy clean-up.
* You can also just spray it lightly with cooking spray
Prep :
Using a sharp knife and a cutting board, slice the 3 bell peppers into thin strips.
Slice 1/2 of a large red onion into thin strips.
Then cut each chicken breast into thin strips.
Place the chicken strips, bell pepper slices, and red onion slices into a large mixing bowl. Drizzle the oil over top and toss to combine everything together.
Sprinkle the chicken taco seasoning over top and mix to combine until everything is well coated in the seasoning.
Place the chicken fajita mix in an even layer on the prepared sheet pan.
Bake for 20 minutes or until the vegetables are fork tender (or softened to your preference) and the chicken reaches an internal temperature of 165° F.
Remove the pan from the oven and drizzle the fresh lime juice over top and sprinkle on the chopped cilantro.
Serve immediately with warmed flour or corn tortillas and any other additional toppings you want.

Notes

Nutrition Information : Amount listed is for 1 serving of the chicken fajitas mixture. It does not include any tortillas or toppings, as that can all vary. One serving is about 1 cup of the fajita mixture.

Recipe Tips -

Use Fresh Lime Juice : For the best flavor use freshly squeezed lime juice from one lime.
Thinly Sliced Onion & Bell Peppers : Make sure that you cut these thin so they'll cook and soften in the bake time given. My family likes softer bell peppers in fajitas so I make sure to cut them really thin so they will soften up quite a bit while baking.
Chicken Strips : Chunks also work. I like thin strips because it matches the shape and size of the sliced onion and vegetables. You just want to make sure that they are not so big that they won't cook in the bake time given. About 1-inch wide strips, maybe slightly smaller, are a great size to aim for. If doing chunks, cut them into small bite-sized pieces.

FAQ's -

How To Store Leftover Chicken Fajitas
- Leftovers store well in an airtight container, in the fridge, for 3-4 days. You can reheat leftovers in the microwave , over the stove, or in the oven. You may need to add a small amount of water when reheating. Make sure that the internal temperature of the chicken is 165 degrees F before serving reheated leftovers.
- Leftovers are also good served cold over top a salad.
- Put leftovers inside a lettuce wrap for a low-carb lunch the next day.
Substitution & Variation Ideas
- Not only are these sheet pan oven baked chicken fajitas easy to make, but they're also so easy to customize too! Here are some ideas.
  - Add Fresh Garlic : Adding some freshly minced garlic, chopped garlic, or garlic paste to the chicken mixture is always a good idea.
  - Seasoning Packet : Although I highly recommend using the chicken taco seasoning packet, you could also use a fajita seasoning mix packet, taco seasoning packet, or use your favorite homemade taco seasoning mix.
  - Chicken : Use chicken tenderloins in place of chicken breast. You will probably still have to slice them but they're smaller so they won't need as much prep work.
  - Bell Peppers : Use any combination of bell peppers that you want!
  - Onion : A sweet onion, white onion, or yellow onion are all great substitutes for the red onion.
  - Make It Spicy! : Add some sliced jalapeños into the fajita mix. Add some cayenne pepper. Use a packet of hot taco seasoning mix. Top the fajitas with shredded pepper jack cheese and/or sliced jalapeños.
Serving Suggestions for Fajitas
- Chicken fajitas are delicious served on tortillas straight out of the oven but there are lots of different serving options.
  - Toppings : Set out bowls with different toppings like shredded lettuce, Pico de Gallo, chopped tomatoes, sour cream, or my Salsa Verde Guacamole. Sliced avocados, jalapeños, salsa, shredded cheese are great topping options.
  - Make Rice Bowls : Serve the chicken fajitas over top some Cilantro Lime Rice or Easy Mexican Rice. Garnish with your favorite toppings or drizzle this amazing Best Cafe Rio Dressing over top.
  - Chicken Fajita Quesadillas : This is a great use for leftovers or cook the recipe as is and use the fajita mix to make quesadillas for dinner.
