Busy weeknights call for simple and crowd-pleasing meals and these sheet pan chicken fajita quesadillas always deliver. You get all the toasted cheese pull and vibrant peppers from a classic fajita but without juggling multiple skillets. Everything bakes together for easy serving and even easier cleanup.
I first made these after a crazy Tuesday when dinner ideas felt impossible. Now we double the batch any time friends come over for movie night.
Ingredients
- Olive oil: provides rich flavor and helps peppers caramelize. Choose extra virgin for best quality
- Red bell pepper: brings sweetness and color. Look for firm and glossy skin
- Green bell pepper: adds slight bitterness and contrast. Select peppers with no wrinkles
- Large onion: for mellow sweetness once roasted. A yellow onion works best here
- Fajita seasoning: or a mix of chili powder cumin and paprika. Choose a blend without fillers or unnecessary salt
- Cooked rotisserie chicken: adds juiciness and keeps prep quick. Tear or shred for the best texture
- Large flour tortillas: soft and flexible for folding but sturdy enough to crisp up. Check for freshness to avoid cracking
- Shredded Mexican blend or cheddar cheese: for melt and creamy tang. Use freshly shredded if possible for best results
- Cooking spray: helps tortillas crisp without adding too much oil
Step-by-Step Instructions
- Preheat the Oven:
- Set oven to 200 degrees Celsius. This ensures tortillas and fillings bake evenly and get crispy
- Prepare the Sheet Pan:
- Line a large pan with parchment for easy cleanup and spray it lightly so nothing sticks
- Roast the Peppers and Onion:
- Toss sliced peppers and onion in olive oil and seasoning in a large bowl so everything is coated. Spread them on half the sheet pan and roast about 10 minutes until softened and slightly golden
- Add the Chicken:
- Scatter shredded rotisserie chicken over roasted veggies and toss well. Roast for another 5 minutes. This blends flavors and warms the chicken through
- Assemble the Quesadillas:
- Lay out tortillas and fill half of each with generous scoops of the chicken veggie mixture and shredded cheese. Fold each tortilla over to make a half moon shape
- Arrange on the Pan:
- Place folded quesadillas on the prepared pan. Spray or brush the tops with a bit more oil for extra crispness
- Bake and Flip:
- Bake quesadillas for about 7 to 8 minutes. When the bottoms look golden and crisp, use a spatula to gently flip. Bake another few minutes until both sides are golden and cheese is melted
- Slice and Serve:
- Transfer quesadillas to a board. Use a sharp knife to slice into wedges. Enjoy hot with your favorite dips on the side

My kids always claim the crispiest edges for themselves and claim quesadilla night is their favorite tradition. Smoked paprika is my secret ingredient and I never skip it for that special Tex-Mex flavor punch.
Storage Tips
Cool leftover quesadillas completely before storing. Stack with a piece of parchment between each to prevent sticking and store in an airtight container in the refrigerator for up to three days. To reheat, pop them back on a sheet pan in a hot oven to restore their crispness. They also freeze well just wrap tightly and thaw before reheating
Ingredient Substitutions
Swap in Monterey Jack or pepper jack cheese for a spicier kick. Use cooked turkey or even sautéed mushrooms for a vegetarian version. Corn tortillas make a good gluten free alternative but they will be more delicate so handle gently
Serving Suggestions
Serve fresh from the oven with bowls of salsa sour cream and guacamole. Add a squeeze of lime over the top or scatter with chopped cilantro for an extra punch. These also pair well with simple rice or a crisp green salad for a balanced dinner
