Ingredients

Scale

Filling

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

Quesadilla Assembly

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

Instructions

  1. Prepare the Veggies: In a large bowl, toss the sliced onions and bell peppers with half of the fajita seasoning and 1 tablespoon of olive oil until coated and glossy.
  2. Sauté the Vegetables: Heat a large cast-iron skillet over medium-high heat and add the seasoned veggies. Cook for 10–12 minutes, stirring occasionally, until soft, lightly charred, and fragrant. Transfer to a plate and set aside.
  3. Season the Chicken: In the same bowl, toss the sliced chicken with the remaining fajita seasoning and the remaining tablespoon of olive oil.
  4. Cook the Chicken: Add the chicken to the hot skillet and cook for 6–8 minutes, flipping halfway through, until golden brown and fully cooked.
  5. Combine Filling: Return the peppers and onions to the skillet with the chicken, squeeze in the lime juice, and stir well to meld the flavors. Remove from heat.
  6. Assemble Quesadillas: Lay a tortilla flat and spoon about ¼ of the fajita filling over one half. Sprinkle generously with shredded cheese, then fold the tortilla over to close.
  7. Cook Quesadillas: Heat a clean skillet or griddle over medium heat and melt about ½ tablespoon of butter. Add the assembled quesadilla and cook for 2–3 minutes per side until golden and crisp. Repeat with remaining quesadillas, adding more butter as needed.
  8. Serve: Slice the cooked quesadillas into halves, sprinkle with fresh cilantro, and serve warm for a melty, cheesy, flavorful meal.

Notes

  • Use a cast-iron skillet for the best sear and flavor when cooking the vegetables and chicken.
  • Butter adds great flavor and browning to the quesadilla; don’t skip it during the cooking step.
  • For a spicier kick, add a pinch of cayenne or chili powder to the fajita seasoning mix.
  • Serve with sour cream, guacamole, or salsa for additional flavor options.
  • Leftover filling can be stored separately and used for other meals like tacos or burritos.
