Equipment

Ingredients

For the Fajita Marinade

  • 2 tablespoons fresh lime juice
  • 2 tablespoons avocado oil (or other neutral oil)
  • ½ teaspoon sugar
  • ½ teaspoon smoked paprika
  • ½ teaspoon granulated garlic
  • ½ teaspoon chili powder
  • 1¼ teaspoons kosher salt

For the Fajitas

  • 1½ pounds boneless, skinless chicken thighs (or breasts), thinly sliced
  • 3 bell peppers (any color), thinly sliced
  • 2 medium onions (white or red), thinly sliced

Instructions

  • Preheat and Prep: Preheat the oven to 400°F. Lightly oil a large sheet pan or line with parchment for easier cleanup.
  • Make the Sauce: In a small bowl, whisk together the lime juice, avocado oil, sugar, smoked paprika, granulated garlic, chili powder, and kosher salt until well combined.
  • Assemble the Fajitas: Add the sliced chicken, bell peppers, and onions directly to the sheet pan. Pour the sauce over everything, then toss well to coat and spread in a single, even layer.
  • Bake: Bake for 25-30 minutes, tossing once halfway through, until the chicken is cooked through and the vegetables are tender and slightly caramelized. For a little char, broil for the last 2-3 minutes.

Notes

  • Serve: Serve warm with tortillas, rice, lime wedges, guacamole, sour cream, or salsa, it’s seriously all good! 
  • Chicken: I tested both chicken breasts and thighs here, and thighs stay juicier and have more flavor, but breasts work great if you slice them thin enough, so basically don't stress about which one you grab.
  • Don’t Overcrowd: Don't overcrowd the pan or everything steams instead of caramelizes. Use a large sheet pan and spread everything into a single even layer before it goes in the oven.
