  • 2 pounds boneless chicken breast cut into strips
  • 1/4 cup lime juice
  • 1/4 cup avocado oil
  • 1 tablespoon garlic minced
  • 1 tablespoon Southwestern seasoning see note
  • Salt and Pepper to taste
  • 3 bell peppers one each green, red, and yellow, cut into strips
  • 3 large onions sliced (or 6 small)
  • For serving: tortillas cheddar cheese, sour cream, limes, cilantro, avocado


  • Place chicken strips in a shallow dish.
  • In a small bowl whisk together lime juice, avocado oil, garlic, and Southwestern seasoning. Reserve 3 tablespoons of the marinade.
  • Pour remaining marinade over chicken and marinate 30 minutes to up to 2 hours.
  • Place a sheet pan in the oven and preheat to 400 degrees.
  • Carefully remove sheet pan and arrange chicken, onions, and peppers on the sheet pan.
  • Bake 25 - 30 minutes, brushing halfway through with reserved marinade.



  • If You don’t have Southwestern Seasoning, use 1 teaspoon chili powder, 1/2 teaspoon each cumin, garlic powder, salt, and paprika. Fajita season or taco seasoning also work.
  • I use organic flour tortillas for the family, and gluten free organic corn tortillas for myself.

Variations for Sheet Pan Chicken Fajitas:

  • Cut a zucchini and yellow squash into matchsticks and toss with a tablespoon of olive oil.  Sprinkle with salt.  Add to the Sheet Pan Chicken Fajitas in the last five minutes of cooking.
  • For a little more heat, add in 1/2 teaspoon crushed red pepper to the marinade.
  • Serve with Avocado Cream or Bacon Guacamole.
  • Instead of serving with cheddar cheese, serve with crumbled quasi fresco or grated Monterey Jack Cheese
