Ingredients

For the Mushroom & Spinach Filling:

  • 2 tbsp extra virgin olive oil
  • 8 oz (225g) cremini or white button mushrooms, sliced
  • 3 cloves garlic, finely minced
  • 3 cups fresh baby spinach
  • ½ tsp dried oregano
  • ½ tsp salt (or to taste)
  • ¼ tsp freshly cracked black pepper

For Assembly:

  • 4 whole wheat or pita flatbreads (or flour tortillas)
  • 1 ½ cups low-moisture mozzarella or provolone cheese, shredded
  • ½ cup crumbled Greek feta cheese (optional, for authentic tang)
  • 1 tbsp extra virgin olive oil or butter (for pan-searing)

Instructions

  1. Sauté the Mushrooms: Heat 2 tablespoons of extra virgin olive oil in a skillet over medium-high heat. Add the sliced mushrooms in a single layer and cook undisturbed for 3 to 4 minutes until golden brown.
  2. Add Garlic & Spinach: Stir in the minced garlic, dried oregano, salt, and black pepper. Cook for 1 minute until fragrant. Toss in the fresh baby spinach and stir for 2 minutes until wilted. Transfer the mixture to a plate.
  3. Assemble Quesadillas: Wipe the skillet clean and return to medium heat. Brush one side of a flatbread/tortilla with olive oil and place it oil-side down in the hot pan.
  4. Layer Filling: Sprinkle a handful of mozzarella/provolone cheese over half of the flatbread. Top with a generous scoop of the garlic mushroom and spinach mixture, crumbled feta (if using), and another layer of cheese. Fold the other half over to create a half-moon shape.
  5. Pan-Sear Until Golden: Cook for 2 to 3 minutes until the bottom crust is deep golden brown and crispy. Carefully flip and cook the second side for another 2 minutes until the cheese is completely melted and bubbly.
  6. Slice & Serve: Remove from heat, let cool for 2 minutes, and slice into halves. Serve warm!

Storage & Reheating

  • Storage: Store leftover cooked quesadillas in an airtight container in the fridge for up to 2 days.
  • Reheating: Reheat in a dry skillet or toaster oven at 375°F (190°C) for 4 to 5 minutes to regain the crispy outer crust.

Pro Tips for Maximum Crispiness

  1. Brown the Mushrooms Well: Avoid moving the mushrooms around too much initially; letting them sear gives them a rich flavor and prevents excess moisture.
  2. Medium Heat is Key: Cook over medium heat so the cheese has time to melt completely before the outer crust browns too quickly.
  3. Double Cheese Layer: Placing cheese both below and above the mushroom filling ensures the flatbread seals tightly when folded.

Frequently Asked Questions

Can I use frozen spinach instead of fresh?

Yes! If using frozen spinach, thaw it completely and squeeze out all excess water with a paper towel before adding it to the skillet.

What cheese works best?

Mozzarella or provolone melts smoothly and provides that photo-worthy cheese stretch, while a sprinkle of Greek feta adds an authentic Mediterranean bite.

Can I make these ahead of time?

You can prepare the mushroom and spinach filling up to 3 days in advance. Assemble and pan-sear right before serving for the crispiest result!
