Ingredients Equipment Method Notes

Ingredients
  

  • 1 tbsp olive oil
  • 3 cups cooked chicken shredded or chopped
  • 2 cups shredded cheese Mexican blend, cheddar, or Monterey Jack
  • 1 cup black beans drained and rinsed
  • 1 cup corn fresh, frozen, or canned
  • 1/2 cup red bell pepper diced
  • 1/4 cup green onions chopped
  • 1 tsp chili powder
  • 1/2 tsp ground cumin
  • 1/2 tsp salt
  • 1/4 tsp black pepper
  • 4 large flour tortillas

Equipment

  • 1 Rimmed baking sheet 9×13-inch or standard sheet pan
  • 1 parchment paper Optional, for easy cleanup
  • 1 Large mixing bowl For combining filling ingredients
  • 1 Measuring cups For accurate ingredient portions
  • 1 Sharp knife For slicing quesadillas
  • 1 Cutting board For prep and slicing

Method
 

  1. Preheat the oven to 425°F (218°C). Line a rimmed baking sheet with parchment paper or lightly grease it with olive oil.
    1 tbsp olive oil
  2. In a large mixing bowl, combine the cooked chicken, shredded cheese, black beans, corn, diced red bell pepper, green onions, chili powder, cumin, salt, and black pepper. Mix until evenly combined.
    3 cups cooked chicken, 2 cups shredded cheese, 1 cup black beans, 1 cup corn, 1/2 cup red bell pepper, 1/4 cup green onions, 1 tsp chili powder, 1/2 tsp ground cumin, 1/2 tsp salt, 1/4 tsp black pepper
  3. Brush one side of each flour tortilla lightly with olive oil. Place two tortillas, oiled-side down, on the prepared sheet pan, overlapping slightly to fully cover the pan.
    4 large flour tortillas, 1 tbsp olive oil
  4. Spread the chicken and cheese mixture evenly over the tortillas, pressing gently into an even layer.
    3 cups cooked chicken, 2 cups shredded cheese
  5. Place the remaining tortillas on top, oiled-side up, covering the filling completely.
  6. Bake for 18–22 minutes, or until the top tortillas are golden brown and crispy. For extra crispiness, broil for 1–2 minutes at the end.
  7. Remove from the oven and let the quesadillas rest for 5 minutes before slicing.
  8. Cut into squares or triangles and serve warm with your favorite toppings.

Notes

• For best results, use burrito-size flour tortillas so the filling stays fully enclosed and the quesadillas bake evenly.
• Rotisserie chicken works great for this recipe and saves time, but any leftover cooked chicken can be used.
• For extra crispiness, brush the top tortillas lightly with olive oil and broil for 1–2 minutes at the end. Watch closely to avoid burning.
• Let the quesadillas rest for 5 minutes before slicing. This helps the cheese set and keeps the filling from spilling out.
• These sheet pan quesadillas are perfect for meal prep. Store leftovers in an airtight container in the refrigerator for up to 4 days and reheat in the oven or air fryer for best texture.
