How to Make Chicken Fajita Quesadillas Recipe
Step 1: Season and Cook the Chicken
Start by tossing your chicken strips in one tablespoon of the fajita seasoning, ensuring each piece is fully coated with that flavorful spice blend. Heat one tablespoon of olive oil in a skillet over medium-high heat, then add the chicken. Cook until the chicken is browned and cooked through, about 6 to 8 minutes, turning to get that lovely color on each side. Once cooked, remove the chicken from the pan and set it aside. Wiping the skillet clean helps prevent burning any leftover bits when you cook the veggies next.
Step 2: Sauté the Veggies and Combine
Using the same skillet, heat the remaining olive oil. Toss in the sliced onions first and sauté until they’re soft and translucent—this releases a natural sweetness that balances the peppers and seasoning. Next, add your red and green bell peppers along with the remaining fajita seasoning. Cook the veggies until they soften slightly without losing their crunch, about 5 minutes. Return the cooked chicken strips to the skillet and stir everything together, letting the flavors marry for about a minute on the heat.
Step 3: Build and Cook the Quesadillas
Melt butter in a clean skillet over medium heat. Place one tortilla in the butter and cook until it turns lightly golden. Flip it, then quickly layer your chicken-vegetable mixture and sprinkle with shredded cheese. Top all of that with another tortilla to create a sandwich. Cook this side until it is golden brown, then carefully flip and cook the other side until equally crisp and the cheese is melted inside. Repeat this process for all tortillas. The butter and medium heat are key to achieving that perfect crispy crust.
Step 4: Slice and Serve
Once your quesadillas are beautifully golden and bubbling with cheese, remove them from the skillet. Use a sharp knife or pizza cutter to slice each quesadilla into quarters. Serve immediately alongside salsa and sour cream to add cool, creamy, and tangy notes that elevate every bite of this Chicken Fajita Quesadillas Recipe.
How to Serve Chicken Fajita Quesadillas Recipe

Garnishes
A pop of fresh garnish can take your quesadillas from delicious to extraordinary. Try a sprinkle of freshly chopped cilantro, a squeeze of lime juice or even some sliced jalapeños for a spicy kick. These extras brighten the richness of the cheese and chicken, balancing each bite with fresh, zesty notes that elevate the entire dish.
Side Dishes
Complement your Chicken Fajita Quesadillas Recipe with classic Tex-Mex sides like Spanish rice, refried beans, or a crisp lettuce and tomato salad. A bowl of homemade guacamole or a spoonful of pico de gallo adds texture and freshness, keeping the meal well-rounded and satisfying. These sides are the perfect accompaniment for finger-friendly quesadillas.
Creative Ways to Present
If you want to dress this up for guests or make an appealing lunchbox option, try stacking the quesadilla quarters on a platter layered with a bed of mixed greens. Add small bowls for salsa, sour cream, and guacamole on the side for dipping. Alternatively, wrap each quarter in parchment paper and tie with colorful twine for fun, portable servings that look as good as they taste.
Make Ahead and Storage
Storing Leftovers
Leftover quesadillas keep beautifully in an airtight container in the refrigerator for up to 3 days. To avoid sogginess, place parchment paper between stacked pieces to preserve that coveted crisp texture.
Freezing
You can freeze the Chicken Fajita Quesadillas Recipe either before or after cooking. If freezing raw, assemble the quesadillas on parchment-lined trays, freeze until firm, then transfer to freezer bags. Cook from frozen by adding a couple more minutes per side. For cooked quesadillas, wrap individually in foil and freeze for up to 2 months.
Reheating
To reheat, use a skillet over medium heat for about 4 to 5 minutes per side, which restores the crispy exterior and melty cheese inside. Avoid microwaving if possible, as it can make the tortillas rubbery and the filling watery.
FAQs
Can I use pre-cooked chicken for the quesadillas?
Absolutely! Using pre-cooked chicken can save time—just toss it with fajita seasoning and quickly heat with the sautéed peppers and onions before filling your quesadillas.
What type of cheese works best for these quesadillas?
Tex-Mex blend and cheddar are classics because they melt beautifully and provide plenty of flavor. You can also experiment with Monterey Jack or a mix of cheeses for extra gooey goodness.
Can I make this dish vegetarian?
Yes! Simply omit the chicken and load up on peppers, onions, and other veggies like mushrooms or zucchini. Add extra cheese or beans for protein and flavor.
What’s the best tortilla to use?
Flour tortillas usually work best for a tender, pliable wrap that crisps up nicely, but corn tortillas add a lovely texture and authentic corn flavor. Choose according to your preference.
How spicy is this Chicken Fajita Quesadillas Recipe?
The fajita seasoning provides warmth and mild heat, but it’s not overwhelmingly spicy. You can always adjust by adding fresh jalapeños or hot sauce if you want to kick the heat up a notch.

Ingredients
Chicken and Vegetables
- 3 boneless, skinless chicken breasts, cut into long strips
- 1 medium red bell pepper, cut into long strips
- 1 medium green bell pepper, cut into long strips
- 2 large onions, sliced
- 2 tablespoons fajita seasoning, divided

Quesadilla Assembly
- 2 tablespoons butter
- 1 cup shredded Tex-Mex cheese or cheddar cheese
- 8 tortillas (flour or corn)
To Serve
- Salsa, for serving
- Sour cream, for serving
Instructions
- Cook the Chicken: Season the chicken strips with 1 tablespoon of fajita seasoning. Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Add the chicken and cook until browned on all sides and cooked through, about 5-7 minutes. Remove the chicken from the skillet and wipe the skillet clean.
- Sauté the Vegetables: In the same skillet, heat the remaining olive oil. Add the sliced onions and sauté until softened, about 4 minutes. Add the red and green bell peppers along with the remaining 1 tablespoon of fajita seasoning and cook until the vegetables are slightly softened, about 5 minutes. Return the cooked chicken to the skillet and stir together for 1 minute to combine the flavors.
- Assemble and Cook the Quesadillas: Melt butter in a separate non-stick skillet over medium heat. Place one tortilla in the skillet and cook until lightly browned, about 1-2 minutes. Flip the tortilla and immediately top it with the chicken and vegetable mixture, sprinkle with shredded cheese, then place another tortilla on top. Cook until the bottom tortilla is golden brown and the cheese begins to melt, about 2-3 minutes, then carefully flip the quesadilla to brown the other side for an additional 2-3 minutes. Repeat this process with the remaining tortillas and filling.
- Serve: Remove the quesadillas from the skillet and cut each into quarters. Serve warm with salsa and sour cream on the side.
Notes
- You can substitute fajita seasoning with a mix of chili powder, cumin, garlic powder, and smoked paprika if you prefer homemade seasoning.
- To make the quesadillas extra crispy, cook on medium-low heat and press down gently with a spatula.
- Use flour tortillas for a softer quesadilla or corn tortillas for a more authentic texture and flavor.
- Leftover chicken fajita filling can be refrigerated for up to 3 days and used as a topping for salads or nachos.
