- ½ cup shredded cheddar cheese
- 2 tablespoons grated Parmesan, optional

Optional Toppings

Instructions
1. Prepare the Vegetables
Wash the mushrooms and spinach. Slice the mushrooms thinly and roughly chop the spinach.
Try to remove excess moisture from the spinach so the quesadillas don’t become soggy.
2. Cook the Mushrooms
Heat 1 tablespoon olive oil in a large skillet over medium-high heat.
Add the sliced mushrooms and cook for 4–5 minutes, stirring occasionally, until they soften and most of their moisture has evaporated.
3. Add the Onion and Garlic
Add the diced onion and cook for 2–3 minutes until softened.
Add the minced garlic and cook for about 30 seconds, just until fragrant.
4. Add the Spinach
Add the chopped spinach.
Cook for 1–2 minutes, stirring, until the spinach wilts.
Season with salt, black pepper, Italian seasoning, and optional red pepper flakes.
Remove from the heat and allow the filling to cool slightly.
5. Assemble the Quesadillas
Place one tortilla on a clean surface.
Sprinkle approximately ⅓ cup shredded mozzarella over half of the tortilla.
Add a portion of the spinach-mushroom mixture.
Sprinkle with cheddar and optional Parmesan.
Fold the tortilla in half to cover the filling.
Repeat with the remaining tortillas and filling.
6. Cook Until Crispy
Heat a clean skillet over medium heat.
Lightly brush the pan with butter or olive oil.
Place one folded quesadilla in the skillet.
Cook for approximately 2–3 minutes per side, gently pressing with a spatula, until the tortilla is golden brown and crispy and the cheese has melted.
Repeat with the remaining quesadillas.
7. Slice and Serve
Transfer the cooked quesadillas to a cutting board.
Let them rest for about 1 minute, then cut each into 2–3 wedges.
Serve immediately with salsa, Greek yogurt, sour cream, avocado, or your favorite dipping sauce.
Tips for Perfect Quesadillas
- Don’t overfill: Too much filling makes the quesadilla difficult to flip.
- Cook mushrooms well: Let excess mushroom moisture evaporate before adding the spinach.
- Use medium heat: This gives the cheese time to melt without burning the tortilla.
- For extra crispiness: Brush the tortilla lightly with olive oil before cooking.
- For extra flavor: Add a little smoked paprika or fresh herbs.
- For more protein: Add cooked shredded chicken or beans.
Air Fryer Method
- Preheat the air fryer to 375°F (190°C).
- Assemble the quesadillas as directed.
- Lightly brush both sides with olive oil.
- Place them in the air fryer basket in a single layer.
- Air fry for 5–7 minutes, flipping halfway through.
- Cook until golden and crispy and the cheese is melted.
Storage
Store leftover quesadillas in an airtight container in the refrigerator for up to 3 days.
For best texture, reheat them in a skillet or air fryer rather than the microwave.

Recipe Q&A
Q: Can I use frozen spinach?
Yes. Thaw it completely and squeeze out as much water as possible before adding it to the skillet.
Q: Can I use different mushrooms?
Yes. Button, cremini, portobello, or a mixture of mushrooms all work well.
Q: Can I make these gluten-free?
Yes. Use certified gluten-free tortillas.
Q: Can I make them vegan?
Yes. Use vegan cheese and a plant-based tortilla, and replace butter with olive oil.
Q: Can I add chicken?
Absolutely. Add about 1 cup of cooked, shredded chicken for a higher-protein version.
Q: Why are my quesadillas soggy?
Usually because the mushrooms or spinach contain too much moisture. Cook the vegetables until excess liquid has evaporated and avoid overfilling.
Q: Can I prepare them ahead?
Yes. Prepare the vegetable filling ahead of time and refrigerate it. Assemble and cook the quesadillas when you’re ready to serve.
Q: What cheese melts best?
Mozzarella, Monterey Jack, Oaxaca, and cheddar are good choices. A combination gives excellent flavor and melt.
Q: What can I serve with them?
Salsa, Greek yogurt, sour cream, guacamole, avocado, or a fresh tomato salad are excellent choices.
