Ingredients
  

Main Ingredients
  • 4 large flour tortillas (10-inch) Use sturdy tortillas so they hold the filling.
  • 6 cups fresh baby spinach It cooks down a lot—don’t be shy.
  • 1 cup crumbled feta cheese Full-fat for creaminess.
  • 1 cup shredded mozzarella cheese Freshly shredded melts best.
  • 1/2 small red onion, thinly sliced So sweet when gently sautéed.
  • 2 cloves garlic, minced Or 1 tsp jarred if you’re in a hurry.
  • 1 tbsp olive oil For sautéing.
  • 1 tbsp lemon juice Brightens everything.
  • 1 tsp lemon zest
  • 1/2 tsp dried oregano Or 1 tsp fresh chopped.
  • 1/4 tsp red pepper flakes Optional, for a gentle heat.
  • Salt and freshly ground black pepper, to taste
  • 1–2 tbsp butter or olive oil For frying the tortillas; butter gives great browning.
  • Fresh parsley or basil for garnish Optional.

Method
 

Preheat & Prepare the Base
  1. Preheat a large nonstick or cast-iron skillet over medium heat.
  2. If you like your finished quesadillas kept warm while you finish others, preheat your oven to 200°F (95°C) and place a baking sheet inside.
  3. Have a clean cutting board, spatula, and a small bowl ready to mix the cheeses and lemon.
Make the Main Filling
  1. Heat 1 tbsp olive oil in the skillet over medium heat. Add the thinly sliced red onion and a pinch of salt; sauté until soft and just caramelized, about 5–7 minutes.
  2. Add the minced garlic and cook 30–45 seconds until fragrant.
  3. Toss in the fresh spinach in batches, stirring until fully wilted, about 2–3 minutes.
  4. Remove the pan from heat and let the spinach mixture cool slightly.
  5. In a bowl, combine the crumbled feta, shredded mozzarella, lemon juice, lemon zest, oregano, red pepper flakes (if using), and a pinch of pepper. Stir in the cooled spinach and onion. Taste and adjust salt/pepper.
Assemble and Chill/Bake
  1. Lay one tortilla flat. Spoon about 1 to 1 1/4 cups of the filling over half the tortilla, spreading evenly but leaving a 1/2-inch border.
  2. Fold the tortilla over to create a half-moon. Press gently to seal.
  3. Melt 1/2 tbsp butter (or brush 1 tsp olive oil) in the skillet over medium-low. Carefully transfer the folded quesadilla; cook until golden brown and crisp, about 2–3 minutes per side.
  4. Transfer cooked quesadilla to the oven-lined baking sheet to keep warm while you crisp the others.
  5. Repeat with remaining tortillas and filling. Let the finished quesadillas rest 1–2 minutes before slicing into wedges.

Notes

Use freshly shredded mozzarella for the creamiest melt. Don’t over-squeeze cooked spinach—leave a touch of moisture so the filling stays juicy but not soggy. Taste the filling before assembling; adjust lemon and pepper to brighten and balance.
