Servings
4 quesadillas
Ingredients
For the Filling:
1 tablespoon olive oil or butter
8 oz (225 g) mushrooms, finely sliced
2 cups fresh spinach, roughly chopped
2 cloves garlic, minced
¼ teaspoon salt
¼ teaspoon black pepper
½ teaspoon Italian seasoning
¼ teaspoon red pepper flakes, optional
For the Quesadillas:
8 medium flour tortillas
1½ cups (150 g) shredded mozzarella cheese
1 cup (100 g) shredded cheddar or Monterey Jack cheese
2 tablespoons grated Parmesan cheese, optional
1 tablespoon butter or olive oil for cooking
Optional Toppings:
Sour cream
Greek yogurt
Salsa
Fresh parsley or cilantro
Sliced green onions
Avocado
A drizzle of hot honey
Instructions
- Sauté the Mushrooms
Heat 1 tablespoon olive oil or butter in a large skillet over medium-high heat.
Add the sliced mushrooms and cook for 5–7 minutes, stirring occasionally, until they release their moisture and become golden brown.
- Add Garlic & Spinach
Add the minced garlic, salt, black pepper, Italian seasoning, and red pepper flakes.
Cook for about 30 seconds until fragrant.
Add the chopped spinach and cook for 1–2 minutes, just until wilted.
Remove from heat and allow the mixture to cool slightly.
Tip: If the mushrooms release a lot of liquid, continue cooking until the pan is mostly dry. This keeps the quesadillas crispy instead of soggy.
- Assemble the Quesadillas
Place one tortilla on a clean surface.
Sprinkle a layer of mozzarella and cheddar over half of the tortilla.
Add some of the spinach-mushroom mixture.
Sprinkle with a little Parmesan, if using, then add another small handful of cheese.
Fold the tortilla in half to form a half-moon.
Repeat with the remaining tortillas and filling.
- Cook Until Golden & Crispy
Heat a clean skillet over medium heat and lightly grease with butter or olive oil.
Place the quesadilla in the skillet and cook for 2–3 minutes per side, gently pressing with a spatula, until golden brown and crisp and the cheese is completely melted.
Repeat with the remaining quesadillas.
- Slice & Serve
Transfer to a cutting board and let them rest for 1 minute.
Cut into wedges and serve warm with sour cream, Greek yogurt, salsa, or your favorite toppings.
Tips for the Best Quesadillas
Cook the mushrooms well: Removing excess moisture is the key to crispy quesadillas.
Don’t overfill: Too much filling can make the tortilla difficult to crisp and flip.
Use a combination of cheeses: Mozzarella gives you the stretchy melt, while cheddar adds more flavor.
Medium heat works best: Very high heat can burn the tortilla before the cheese melts.
For extra crispiness: Brush the tortillas very lightly with oil or butter before cooking.
Make them spicy: Add jalapeños, chili flakes, or a drizzle of hot sauce.
For extra protein: Add shredded chicken, black beans, or a little cottage cheese to the filling.

Recipe Q&A
Can I use frozen spinach?
Yes. Thaw it completely and squeeze out as much water as possible before adding it to the mushrooms.
How do I keep quesadillas crispy?
Make sure the mushroom mixture isn’t watery, don’t overfill the tortillas, and cook over medium heat until both sides are golden brown.
Can I make these ahead of time?
Yes. Prepare the mushroom-spinach filling ahead of time and refrigerate it for up to 3 days. Assemble and cook the quesadillas when ready to serve.
Can I freeze quesadillas?
Yes. Let cooked quesadillas cool completely, separate them with parchment paper, and freeze in an airtight container or freezer bag for up to 2 months.
How do I reheat them?
For the crispiest result, reheat in a skillet, air fryer, or oven rather than the microwave.
Can I add other vegetables?
Absolutely. Bell peppers, onions, zucchini, corn, or roasted tomatoes are delicious additions.
Can I add meat?
Yes. Shredded chicken, cooked ground beef, turkey, or chopped cooked bacon can be added for extra protein.
What cheese melts best?
Mozzarella, Monterey Jack, Oaxaca, cheddar, and a Mexican cheese blend all work well.
Can I make these vegetarian?
Yes. The recipe as written is vegetarian.
Are these keto-friendly?
Traditional flour tortillas are not particularly low in carbohydrates. For a lower-carb version, use low-carb tortillas and check their nutrition labels.
Can I make them in an air fryer?
Yes. Assemble the quesadillas, lightly spray or brush them with oil, and air fry at 375°F (190°C) for about 5–7 minutes, flipping halfway through, until crisp and melted.
What can I serve with these quesadillas?
Serve them with salsa, guacamole, Greek yogurt, sour cream, tomato salad, roasted vegetables, or a simple green salad.
Why are my quesadillas soggy?
The most common reason is excess moisture from the mushrooms or spinach. Cook the vegetables until most of their moisture has evaporated and avoid overfilling.
Can I use baby spinach?
Yes. Baby spinach works perfectly and cooks very quickly.
Serving Suggestion
Serve these golden, crispy quesadillas hot with fresh salsa, creamy avocado, and a dollop of Greek yogurt or sour cream for an easy and satisfying meal.
