INGREDIENT NOTES:

  • Chicken: I used boneless, skinless chicken breasts, but you can also substitute chicken thighs for a juicier option.
  • Bell Peppers: A mix of red and green bell peppers adds a nice flavor and color, but feel free to add poblanos or any of your favorite peppers for variety.
  • Tortillas: Large flour tortillas work perfectly here, but you can swap for whole wheat or gluten-free options if needed.

HOW TO MAKE CHICKEN QUESADILLAS STEP-BY-STEP:

Check out the quick visual guides below. For full instructions and ingredients, see the printable recipe card at the end.

STEP 1: In a large nonstick skillet, heat 1 tablespoon of vegetable oil over medium-high heat. Add the chicken, bell peppers, and onion, then sprinkle with chili powder, cumin, salt, garlic powder, and black pepper. Cook for 5-7 minutes, stirring occasionally, until the vegetables are soft and the chicken fajita mixture is heated through.

STEP 2: Transfer the cooked chicken fajita mixture to a small bowl and set aside. Wipe the skillet clean with a paper towel.

STEP 3: Return the skillet to medium-high heat and add remaining oil or cooking spray. Place a tortilla in the skillet, then sprinkle Colby Jack cheese over half of each tortilla.

STEP 4: Spoon 1/3 cup of the chicken fajita mixture on top of the cheese. Fold the tortilla in half over the filling.

STEP 5: Cook for 2-3 minutes, until the bottom tortilla is golden brown and the cheese is gooey and melted. Flip and cook the other side for another 2 minutes.

STEP 6: Repeat with the remaining tortillas and filling, adding a little oil  to the skillet for each new quesadilla.

STEP 7: Cut each quesadilla in half on a cutting board and serve with pico de gallo, sour cream, or salsa if desired.

PRO TIP:

For extra flavor, squeeze a little lime juice over the chicken fajita mixture before folding the quesadillas. It adds a zesty kick!

Storage and Reheating

Storage: Store any leftover quesadillas in the refrigerator in an airtight container. It can be kept for up to 3 days.

Reheating: Reheat in a skillet over medium heat to keep them crispy, or in the oven at 350°F for about 10 minutes. You can also use the microwave for a quicker option, but the tortillas won’t be as crispy.

Freezing: Cool completely, wrap in plastic, and freeze up to 2 months. To reheat, place them on a baking sheet in the oven at 350°F for about 10 minutes until heated through and crispy again.

Additions & Substitutions

ADDITIONS:

  • Add some orange bell peppers or poblano pepper for more veggie goodness!
  • Add jalapeños for extra heat or fresh cilantro for a burst of flavor.

SUBSTITUTIONS:

  • Chicken: Use boneless, skinless chicken breasts or chicken thighs, depending on your preference. For extra fast, grab a rotisserie chicken from the grocery store.

  • Onions: You can use red onions instead.
