Start by preheating your oven to 400°F (200°C). While it’s heating up, grab a large baking sheet and lightly grease it with cooking spray or olive oil. This ensures a crispy finish on your quesadillas.
Next, take your chicken breasts and place them in a ziplock bag or a large bowl. Sprinkle the fajita seasoning over the chicken, ensuring that each piece is well coated. This step is crucial for flavor, so don’t rush it!
In a heavy-duty pan, heat 1 tablespoon of olive oil over medium-high heat for about 2 minutes until it’s hot. Carefully add the seasoned chicken to the pan and cook for about 5 to 6 minutes on each side or until the chicken is golden brown and cooked through. You’ll know it’s ready when the juices run clear and the meat is no longer pink.
Once cooked, remove the chicken from the pan and let it cool for about 4 to 5 minutes. Then, chop it into small, bite-sized pieces. This makes it easier to fill your tortillas later on.
In the same pan, add the sliced onion and bell peppers. Cook on high heat for 2 to 3 minutes, stirring occasionally, until they are lightly charred and caramelized. The sweetness of the vegetables will complement the spices beautifully.
Now it’s time to assemble your quesadillas. Take the prepared tortillas and lay them on the greased baking sheet. On one half of each tortilla, add 1/4 of the chopped chicken, followed by 1/4 of the bell pepper and onion mixture, and then top it off with 1/4 cup of your favorite shredded cheese. Fold the other half of the tortilla over to create a pocket.
Lightly spray the tops of the folded tortillas with cooking spray. This will help them achieve that perfect golden brown color while baking.
Place the baking sheet in your preheated oven and bake for 10 minutes. After that, carefully flip each quesadilla and bake for another 10 minutes. They should be crispy and golden brown when they’re done.
Once baked, remove the quesadillas from the oven and let them cool slightly. Serve immediately while they’re hot, with salsa, sour cream, or guacamole on the side for dipping. Enjoy the flavors and the company of your loved ones!
