- Top & press: Place the last 2 tortillas on top, fold overhanging tortillas inward, and cover with a second baking sheet to press.
- Bake: Bake 10 minutes. Remove the top pan and bake 8–12 minutes more, until tortillas are golden and crispy.
- Serve: Slice into rectangles and serve with your favorite toppings.

Recipe Notes
Easy Chicken Options
You can use thinly-sliced chicken breast, leftover cooked chicken, rotisserie chicken, or canned chicken. If using pre-cooked chicken, add it after the peppers soften and heat just until warmed through.
Prevent Soggy Quesadillas
- Use a slotted spoon to scoop the filling so excess liquid stays in the pan.
- Cook off extra moisture for 1–2 minutes before assembling if the filling looks wet.
- Remove the top baking sheet for the final bake so the tortillas get golden and crispy.
Pan Size
This recipe can be used for either a 18 x 13-inch half-sheet pan or 13 x 9-inch quarter sheet pan.
Cheese Tips
Mexican blend works great, but cheddar, Monterey Jack, pepper jack, or a mix of cheeses are all delicious. Shred your own cheese for the best melt.
Make It Your Way
Try black beans and corn for a vegetarian version, or swap in cooked steak, shrimp, or turkey. Add heat with jalapeños, hot sauce, or pepper jack cheese.
Storage & Reheating
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or air fryer until crisp. The microwave works, but the tortillas won’t stay as crispy.
Frequently Asked Questions
Can I use rotisserie chicken or canned chicken?
Yes. Rotisserie chicken, leftover chicken, or canned chicken all work. Because they’re already cooked, add them near the end and heat just until warmed through.
How do I keep sheet pan quesadillas from getting soggy?
Use a slotted spoon to add the filling so extra liquid stays behind. If the mixture looks wet, simmer 1–2 minutes to reduce moisture. Baking uncovered at the end helps crisp the tortillas.
What size pan should I use?
A 18 x 13-inch half-sheet pan or 13 x 9-inch quarter sheet pan works. If you use the larger pan, use the larger tortillas (10-inch - 12-inch) or if using the smaller pan, use the smaller flour tortillas (8-inch).
Can I make sheet pan quesadillas ahead of time?
You can cook the chicken and peppers ahead and refrigerate. For best texture, assemble and bake right before serving so the tortillas stay crispy.
What tortillas work best?
8-inch flour tortillas are ideal because they fold neatly over the edges. Burrito-size tortillas can work, but you may need fewer.
Can I freeze sheet pan quesadillas?
Yes. Cool completely, wrap tightly, and freeze. Reheat in the oven or air fryer until hot and crispy.
What toppings go best with these quesadillas?
Pico de gallo, guacamole, Mexican crema (or sour cream), sliced jalapeños, fresh cilantro, and lime wedges are all great choices.
