  • Vegetable Oil
  • Chicken Breast
  • Yellow Onion
  • Red & Green Bell Pepper
  • Tortillas – I like flour tortillas because they’re softer, chewy, and more pliable, making them easier to fold. But you could use corn tortillas for a firmer texture and nuttier flavor. 
  • Shredded Cheddar Cheese

Fajita Seasoning Mix

  • Chili Powder
  • Ground Cumin
  • Paprika
  • Garlic Powder
  • Onion Powder
  • Salt & Pepper

How to Make Fajitas Quesadillas

  • Prepare Fajita Seasoning Mix. In a small bowl, blend the fajita seasoning mix until thoroughly combined.
  • Coat Chicken with Seasoning. Toss the chicken with the seasoning mix until evenly coated.
  • Cook Chicken and Vegetables. Heat oil in a large skillet over high heat, then add chicken and vegetables. Cook, stirring frequently, for 5-6 minutes until chicken is fully cooked.
  • Assemble Quesadillas. Place four tortillas on a work surface, spreading 1/4 cup of cheese on each. Divide the cooked chicken filling among the tortillas, then sprinkle with the remaining cheese. Top with another tortilla.
  • Cook Quesadillas. Heat a large skillet or griddle over medium-high heat. Brush one side of each quesadilla with oil and place oil-side down in the pan. Brush the other side with oil. Cook for 3-4 minutes until the cheese melts and the tortilla turns golden. Flip and cook for an additional 3-4 minutes.
  • Serve. Remove from heat, slice, and serve with salsa, sour cream, or guacamole for dipping. Enjoy your delicious fajita quesadillas!

Recipe Tips & Suggestions

  • Corn Tortilla Considerations: If you want to use corn tortillas instead, warm them up first! Add them to a hot, dry pan and let them heat up on each side before adding the filling. This way, they won’t crack or break when you fold them. 
  • Don’t Overfill Quesadillas. Avoid overfilling the quesadillas to prevent them from becoming too difficult to handle or spilling out while cooking.
  • Experiment With Fillings. I love adding tomato and black olive to mine, and my husband adds banana peppers to spice things up. Take a look at what you have on hand, and load up these quesadillas!
  • Don’t Overcrowd the Pan. Cook the quesadillas in batches if necessary to avoid overcrowding the pan, ensuring even cooking and crispy edges.
  • Use the Air Fryer. Follow my Air Fryer Quesadillas method of cooking to make them fast and easy and get super crispy!

Topping Suggestions

You an take your quesadilla over the top by what you serve with it! Dips make all the difference.

Can I use store-bought fajita seasoning for this recipe?

Absolutely! Store-bought fajita seasoning works perfectly for adding delicious flavor to the chicken and veggies.

Can I use other proteins besides chicken?

Yes, feel free to swap out the chicken for steak, shrimp, or even tofu to suit your preferences or dietary restrictions. Or skip the meat and use just Fajita Veggies instead!

Can I make these quesadillas ahead of time?

While they’re best enjoyed fresh, you can prepare the filling in advance and assemble the quesadillas just before cooking for a quicker meal prep option.
