Method

  1. Preheat the oven to 425°F (425°F).

  2. Slice the chicken breasts (and thighs, if using) into thin strips and spread them on a large sheet pan.

  3. Slice the onion and all three peppers into strips and add them to the pan with the chicken.

  4. Season the chicken and vegetables with 2‑3 tsp salt, 1 tsp black pepper, 1 tbsp paprika, 2 tsp cumin powder, and 2 tsp garlic powder.

  5. Drizzle 0.3 cup olive oil over the mixture and toss everything together until evenly coated.

    Kitchen notes · Added by ReelsMeals: evenly coated chicken and vegetables. Toss with oil and seasonings before spreading in a single layer.

  6. Spread the mixture into an even layer and bake for 20‑25 minutes, stirring once halfway through.

    Kitchen notes · Added by ReelsMeals: tender roasted fajita filling. Stir halfway through baking for even cooking.

  7. While the fajitas bake, prepare the guacamole: mash the ripe avocados in a bowl, then stir in the finely chopped onion, optional Serrano chili, chopped cilantro, lime juice, and salt to taste.

    Kitchen notes · Added by ReelsMeals: chunky guacamole. Mash avocado and fold in onion, chili, cilantro and lime.

  8. After the bake, give the chicken and vegetables a quick toss and switch the oven to broil for 2‑3 minutes, watching closely until slightly charred.

    Kitchen notes · Added by ReelsMeals: slightly charred edges. Broil briefly while watching closely, then serve in warm tortillas.

  9. Remove from the oven, let rest for a couple of minutes, then serve the warm fajita mixture in tortillas with a generous spoonful of guacamole, extra cilantro, and an additional squeeze of lime if desired.
