These mushroom spinach quesadillas have become a regular fixture in my kitchen because they’re quick to prepare and deliver a satisfying, savory bite. I love how the earthy mushrooms and tender spinach meld together, balanced by gooey cheese and a crisp tortilla. It’s a dish I turn to when I want something comforting but not heavy.

I often serve these for lunch or as a light dinner, especially when I have leftover veggies in the fridge. The aroma of sautéed mushrooms fills the kitchen, and the golden, crispy tortillas are always a hit at the table. They’re easy to slice and share, making them great for casual gatherings or a family meal.

What makes this recipe special is its flexibility. You can dress it up with extra toppings or keep it simple. The combination of flavors and textures—earthy, creamy, crisp—keeps everyone coming back for more.

These quesadillas are also a handy way to use up odds and ends in the fridge. I like to serve them with salsa or a dollop of sour cream, but they’re just as good on their own.

Ingredients

The ingredient list is straightforward, relying on fresh mushrooms, spinach, and cheese for most of the flavor. I use flour tortillas, but you can swap in your favorite type. Everything is easy to find at the grocery store, and you can adjust the cheese or add extras as you like.

• 2 tablespoons olive oil
• 8 ounces cremini or white mushrooms, sliced
• 2 cups fresh baby spinach, roughly chopped
• 1 small yellow onion, finely diced
• 2 cloves garlic, minced
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper
• 1/2 teaspoon dried oregano or thyme
• 4 large flour tortillas (8-inch)
• 1 1/2 cups shredded Monterey Jack or mozzarella cheese
• Butter or extra oil for the pan (optional)

Step-by-Step Instructions

These quesadillas come together in just a few steps. Sauté the filling, assemble, and cook until golden and crisp. Keep an eye on the heat so the tortillas don’t burn before the cheese melts.

1. Heat 1 tablespoon olive oil in a large skillet over medium heat.
2. Add the diced onion and cook for 2 minutes until softened.
3. Stir in the mushrooms and cook for 5–6 minutes, stirring occasionally, until they release their moisture and begin to brown.
4. Add the garlic, salt, pepper, and dried oregano or thyme. Cook for 1 minute until fragrant.
5. Add the chopped spinach and cook for 1–2 minutes, just until wilted. Transfer the mixture to a bowl and wipe out the skillet.
6. Lay out the tortillas. On half of each tortilla, sprinkle a layer of cheese, then spoon over the mushroom-spinach mixture. Top with more cheese, then fold the tortilla over to close.
7. Heat the remaining oil or a little butter in the skillet over medium heat. Place 1–2 quesadillas in the pan (depending on size).
8. Cook for 2–3 minutes per side, pressing gently, until golden brown and cheese is melted.
9. Transfer to a cutting board, let cool briefly, then slice into wedges.
10. Repeat with remaining quesadillas. Serve warm, with salsa or sour cream if desired.

Chef Tips

A few simple tricks make these quesadillas even better. Use medium heat to avoid burning, and don’t overstuff the tortillas. Here are some more tips to help you get the best results every time.

• Pat mushrooms dry before slicing to avoid soggy filling.
• Let the filling cool slightly before assembling to prevent soggy tortillas.
• Press down gently with a spatula for extra crispness.
• Wipe out the skillet between batches if needed.
• Use pre-shredded cheese for convenience.

Substitutions

This recipe is flexible, so you can swap ingredients based on what you have. The flavor will shift slightly, but the method stays the same. Here are some easy substitutions to try.

• Use whole wheat or corn tortillas instead of flour.
• Swap Monterey Jack for cheddar, mozzarella, or pepper jack.
• Try kale or arugula in place of spinach.
• Use portobello or shiitake mushrooms for a deeper flavor.
• Add cooked beans or roasted peppers for extra filling.

Storage & Reheating

Quesadillas are best fresh, but leftovers keep well for a day or two. Store them in the fridge and reheat for a quick snack or meal. Here’s how to keep them tasting their best.

• Cool completely before storing in an airtight container.
• Refrigerate for up to 2 days.
• Reheat in a skillet over medium heat for best crispness.
• Microwave for 30–45 seconds if you’re in a hurry.
• Avoid freezing, as the texture may suffer.

Perfect Pairings

These quesadillas are versatile and pair well with a variety of sides and drinks. I like to serve them with something fresh or tangy to balance the richness. Here are a few ideas to round out your meal.

• Fresh tomato salsa or pico de gallo
• Simple green salad with lime vinaigrette
• Guacamole and tortilla chips
• A light, crisp white wine such as Sauvignon Blanc
