Easy Sheet Pan Fajita Chicken for a Weeknight Win

I don’t know what I would do without sheet pan dinners. They’re a lifesaver on busy weeknights, and if you love easy one pan meals like sausage and vegetables or balsamic chicken and veggies, this one’s for you.

These chicken fajitas need just 5 main ingredients: sliced chicken, bell peppers, onion, fajita seasoning and tortillas. The veggies get a head start in the oven so nothing turns soggy, then everything roasts on one foil-lined pan and is ready in 30 minutes. Pile it all into the warm tortillas with your favorite toppings and dinner is done, with barely a dish to wash.

Recipe Ingredients

Sliced bell peppers on a cutting board.
  • Chicken: You’ll need about 1 pound chicken breast or 2 large pieces, sliced into strips.
  • Bell peppers and onion: I use a mixture of red, green and yellow chopped bell peppers. Feel free to use pepper color of choice. White are sweet onion are best for fajitas.
  • Fajita seasoning: I love to use my homemade fajita seasoning when I have a batch of it on hand. Your favorite store bought brand works, too.
  • Oil: The oil helps the seasoning stick to the chicken and veggies. I use about 2 Tablespoons.
  • Tortillas: We typically use flour tortillas, but corn tortillas work great too.

How to Make Sheet Pan Chicken Fajitas

  1. Prepare. Preheat the oven to 415°F and line your baking sheet with foil. This helps make clean up so much easier! Add the veggies to the pan and bake for 3-5 minutes while you slice the chicken.
  2. Bake. Remove the pan from oven and add sliced chicken. Drizzle olive oil on top and sprinkle on seasoning. Toss to coat. Bake for 20-25 minutes (stirring halfway through), until the chicken is cooked through and veggies are tender.
  3. Serve. Pile the sheet pan chicken fajitas into a tortilla, serve over a bed of rice or on top of a salad. Add your favorite toppings and dig in!

Ingredients 

  • 3 bell peppers
  • ½ onion
  • 1 ½ pounds boneless skinless chicken breasts , sliced
  • 2 Tablespoons olive oil
  • 1-2 Tablespoons Fajita seasoning (or taco seasoning)
  • 8 small flour or corn tortillas (or lettuce wraps)
  • Salt & Pepper (to taste)

Optional toppings: Fresh limes, chopped cilantro, avocado slices or guacamole, shredded cheese, sour cream, salsa

Instructions

  • Preheat the oven to 415°F and line a large rimmed baking sheet with foil. Spray with nonstick spray.
  • Slice the peppers and onions and place onto the pan. Bake for 3 to 5 minutes, while you slice the chicken.
  • Then place the chicken on the pan and drizzle the olive oil over the top and sprinkle on the Fajita seasoning. Toss to coat.
  • Bake for 20 minutes, or until the chicken is cooked through and the vegetables are fork tender. I like to stir the vegetables half way through, and drain off any excess liquid from the pan around 15 minutes. If you like your vegetables a little more browned, bump up the heat to 425°F half way through. Add salt and pepper to taste.
  • Enjoy the fajita chicken inside a tortilla, on top of a bed of rice or salad if you’re watching your carbs. Top with your favorite toppings.

Notes

Marinate: If you have extra time, marinate the chicken with the olive oil and Fajita seasonings for about an hour beforehand. You can also buy a fajita sauce (Frontera makes one) to marinate the chicken in. 
If you’d like to add more vegetables, feel free to add mushrooms and squash as well.
Wrap the tortillas in foil and place in the pan the last 5 minutes, to warm them up.
Storing leftovers: Store the chicken and veggies in an airtight container in the refrigerator up to 4 days. Reheat in a skillet over medium heat or in the microwave until warmed through. I don’t recommend freezing after cooking, since the peppers turn watery once thawed.
To freeze ahead, place the raw sliced chicken and veggies with the seasoning and oil in a freezer bag up to 3 months, then thaw overnight and bake as directed.
