Ingredients

Scale

Filling

  • 1 lb chicken breast, thinly sliced
  • 1 medium white onion, sliced
  • 1 red bell pepper, sliced
  • 1 green bell pepper, sliced
  • 1 1 oz packet fajita seasoning, divided
  • 2 tbsp olive oil, divided
  • Juice from 1 lime

Quesadillas

  • 4 large burrito-style flour tortillas
  • 1 ½ cups shredded quesadilla or Mexican blend cheese
  • 2 tbsp salted butter, divided
  • Fresh cilantro, chopped (for garnish)

Instructions

  1. Prepare the Vegetables: In a large bowl, toss the sliced onions and bell peppers with half of the fajita seasoning and 1 tablespoon of olive oil until they are evenly coated and glossy.
  2. Sauté the Vegetables: Heat a large cast-iron skillet over medium-high heat, then add the seasoned vegetables. Cook, stirring occasionally, for 10–12 minutes until they soften, develop a slight char, and release a fragrant aroma. Remove and set aside on a plate.
  3. Season the Chicken: In the same bowl used for the vegetables, toss the thinly sliced chicken breast with the remaining fajita seasoning and the remaining tablespoon of olive oil, ensuring thorough coating.
  4. Cook the Chicken: Add the chicken to the hot skillet and cook for 6–8 minutes, flipping halfway through, until the chicken is golden brown and fully cooked.
  5. Combine Filling: Return the cooked peppers and onions to the skillet with the chicken, squeeze in the lime juice, and stir everything together to meld the flavors. Remove the skillet from heat.
  6. Assemble Quesadillas: Lay one flour tortilla flat and spread approximately one-quarter of the fajita filling over half of the tortilla. Generously sprinkle shredded cheese over the filling, then fold the tortilla in half to enclose the filling.
  7. Prepare to Cook Quesadillas: Heat a clean skillet or griddle over medium heat and melt about half a tablespoon of butter.
  8. Cook Quesadillas: Place the assembled quesadilla in the skillet and cook for 2–3 minutes per side until the tortilla is golden and crisp and the cheese is melted inside. Repeat the process for the remaining tortillas, adding more butter to the skillet as needed.
  9. Serve: Slice each quesadilla into halves, garnish with chopped fresh cilantro, and serve warm to enjoy melty, cheesy perfection.

Notes

  • Use a cast-iron skillet or heavy-bottomed pan for best heat retention and even cooking.
  • Adjust fajita seasoning quantity to taste or use homemade seasoning for a fresher flavor.
  • Butter adds richness and crispness; substitute with margarine or oil if preferred.
  • Serve with sour cream, guacamole, or salsa for extra flavor accompaniments.
  • Leftovers can be stored in the refrigerator for 2 days and reheated in a skillet to maintain crispiness.
