Ingredients

For the Quesadillas

  • 2 tablespoons olive oil
  • 1 pound lean ground beef
  • 1 yellow onion cored and finely chopped
  • 1 red bell pepper cored and finely chopped
  • 1 15-ounce can black beans drained and rinsed
  • 1 5-ounce can mild green chiles
  • 3 tablespoons taco seasoning plus additional to taste
  • ½ teaspoon kosher salt plus more to taste
  • ½ teaspoon black pepper
  • ¼ cup water
  • Cooking spray
  • 10 medium 10-inch flour tortillas
  • 16 ounces grated cheddar cheese or Mexican blend cheese

For Serving

  • Salsa
  • Sour cream
  • Guacamole

Instructions
 

Preheat the Oven

  1. Preheat the oven to 350°F (175°C). Position a rack in the center of the oven.

Prepare the Filling

  1. Heat the olive oil in a large skillet over medium heat. Add the ground beef and cook for 4–5 minutes, breaking it into small pieces as it browns.
  2. Add the chopped onion, red pepper, black beans, and mild green chiles. Continue cooking for 5–6 minutes, or until the vegetables soften but do not brown.

Season the Filling

  1. Add the taco seasoning, salt, pepper, and water. Cook for 3–4 minutes, stirring regularly, until the water evaporates and the mixture is evenly seasoned.
  2. Remove from heat and adjust seasoning as desired.

Assemble the Quesadilla

  1. Coat a 9×13-inch sheet pan with cooking spray.
  2. Arrange 2 tortillas overlapping in the center of the pan, then place 6 tortillas around the edges so that the excess hangs over the sides.
  3. Sprinkle one-third of the cheese onto the tortilla base. Spread the prepared filling evenly across the surface, then top with the remaining cheese.
  4. Place the remaining 2 tortillas in the center, then fold the overhanging tortilla edges inward to fully enclose the filling.
  5. Spray the surface lightly with cooking spray.

Bake

  1. Cover the assembled quesadilla by placing a second, slightly smaller sheet pan or baking dish on top. Use a piece of foil between the quesadilla and the upper pan to prevent sticking.
  2. Transfer to the oven and bake for 20 minutes.

Crisp the Exterior

  1. Remove the top pan and foil. Increase the oven temperature to 400°F (200°C) and bake for an additional 10–15 minutes, or until the tortillas are crisp and golden.

Cool and Slice

  1. Remove from the oven and allow the quesadilla to rest for 10 minutes before cutting.
  2. Slice into squares or rectangles and serve warm with salsa, sour cream, and guacamole.

Notes

To make Easy Sheet Pan Quesadillas gluten-free, substitute the flour tortillas with certified gluten-free tortillas. Ensure your taco seasoning is labeled gluten-free, as some blends may contain additives or wheat-based fillers. Baking time may vary slightly due to different tortilla textures; monitor closely to prevent over-crisping.
