Ingredients

Scale

For the Grilled Vegetables

  • 2 zucchini, sliced into 1/2-inch thick rounds
  • 2 yellow squash, sliced into 1/2-inch thick rounds
  • 4 large portobello mushrooms, stems removed
  • 4 red bell peppers, quartered and seeded
  • 1 large red onion, cut into 1/2-inch thick wedges
  • 1 tsp Morton Kosher salt
  • 1/2 tsp freshly cracked black pepper
  • 1 tbsp balsamic glaze (optional for finishing)

For the Assembly

  • 4 large flour tortillas
  • 1 1/2 cups shredded mozzarella cheese
  • 1/2 cup shredded parmesan cheese
  • 8 tbsp basil pesto

Instructions

  1. Prepare and Season Vegetables: Slice zucchini and yellow squash into 1/2-inch rounds, keep portobello mushroom caps whole and remove stems, quarter and seed the red bell peppers, and cut the red onion into 1/2-inch thick wedges. Pat all vegetables dry with paper towels, then season both sides generously with kosher salt and freshly cracked black pepper. This ensures even seasoning and helps develop a nice char when grilling.
  2. Grill Vegetables: Preheat the grill to 300-350°F. Place all seasoned vegetables on the grill grates. Grill each side for 3-4 minutes until you see well-defined char marks and the vegetables are tender. Grill the peppers until charred on the outside for enhanced flavor, and grill mushrooms last as they absorb heat differently.
  3. Cool and Prep Grilled Peppers: Transfer grilled vegetables to a cutting board to cool slightly. Once peppers are cool enough, carefully peel away the charred skin, remove any remaining seeds, and rinse under cool water. Chop the peppers into bite-sized pieces. Chop or slice the zucchini, squash, mushrooms, and onions into manageable pieces for the quesadillas and set aside.
  4. Assemble Quesadillas: Lay one flour tortilla on a clean surface. Spread 2 tablespoons of basil pesto evenly over the entire tortilla. On one half, arrange about 1/4 of the chopped vegetables, then sprinkle 1/4 of the mozzarella (3-4 tablespoons) and 2 tablespoons parmesan cheese over the veggies. Fold the tortilla in half to form a half-moon shape, pressing gently to secure. Repeat with remaining tortillas and ingredients.
  5. Pan-Sear Quesadillas: Heat a large skillet or griddle over medium-high heat. Place one assembled quesadilla in the hot pan and cook for about 3 minutes until the bottom is golden brown and crispy. Carefully flip and cook the other side for another 3 minutes until evenly browned and cheese is melted. Use a wide spatula to prevent filling from spilling. Repeat with remaining quesadillas, avoiding overcrowding.
  6. Finish and Serve: Transfer cooked quesadillas to a cutting board and let rest for 1-2 minutes. Cut each quesadilla into four triangular pieces. Optionally, drizzle with balsamic glaze before serving. Serve warm with your choice of sour cream, salsa, guacamole, or a fresh salad.

Notes

  • Pat vegetables dry after grilling to avoid soggy quesadillas.
  • Do not overcrowd the tortillas when assembling to make flipping easier without filling spilling out.
  • Salt zucchini and squash before grilling to draw out excess moisture and prevent watery fillings.
  • Ensure pan is preheated to medium-high heat for crispy tortillas and fully melted cheese.
  • Use a wide spatula for flipping to maintain quesadilla integrity.
  • Store leftovers in an airtight container in the fridge for up to 3 days, or freeze assembled but uncooked quesadillas for up to 2 months.
  • Reheat leftover quesadillas in a dry skillet or air fryer to restore crispiness instead of microwaving.
