Ingredients

• Spinach: Fresh spinach adds vibrant color, nutrients, and a mild flavor that pairs perfectly with mushrooms. You can substitute with frozen spinach (thawed and drained) in a pinch.
• Mushrooms: Any variety works well – cremini for earthiness, white button for mildness, or portobello for meatier texture. Slice them evenly for consistent cooking.
• Olive Oil: Used for sautéing the vegetables. You can substitute with avocado oil or butter for different flavor profiles.
• Garlic Powder: Provides concentrated garlic flavor without the risk of burning. Fresh minced garlic can be used instead if you prefer.
• Onion Powder: Adds savory depth without the texture of chopped onions. For more texture, substitute with finely diced fresh onion sautéed with the mushrooms.
• Dried Thyme: Optional herb that complements mushrooms beautifully. Rosemary or oregano can be excellent alternatives.
• Cheese: A good melting cheese is essential – cheddar for sharpness, mozzarella for stretch, or use a Mexican blend for authentic flavor.
• Flour Tortillas: Large-sized tortillas work best for folding. Whole wheat tortillas can be substituted for added fiber.
• Salt and Pepper: Essential for seasoning the vegetable filling to perfection.
• Cooking Spray/Olive Oil: For brushing the quesadillas before baking to achieve that golden-brown crispiness.

Variations

Mediterranean Style

Transform these quesadillas with Mediterranean flavors by adding chopped artichoke hearts, a sprinkle of feta cheese, and substituting the thyme with dried oregano. Before serving, drizzle with a little balsamic glaze for an extra flavor dimension.

Spicy Mexican

Give these quesadillas a kick by adding diced jalapeños or green chilies to the vegetable mixture. Use a Mexican cheese blend and add a teaspoon of taco seasoning to the vegetables while cooking. Serve with fresh pico de gallo and guacamole.

Breakfast Quesadillas

Turn this into a morning meal by adding scrambled eggs to the spinach and mushroom mixture. Use breakfast-friendly cheeses like cheddar or Gruyère, and consider adding a few pieces of crumbled bacon for additional flavor. Serve with hot sauce and a dollop of sour cream.

How to Make the Recipe

Step 1: Prepare the Vegetables

Begin by heating olive oil in a skillet over medium heat. Add the sliced mushrooms and cook until they release their moisture and begin to brown, about 5 minutes. Stir occasionally to ensure even cooking. Add the chopped spinach to the skillet and cook until it wilts down completely, which should take about 2 minutes. Season the mixture with garlic powder, onion powder, dried thyme (if using), salt, and pepper, then stir to combine all flavors. Remove the skillet from heat and allow the mixture to cool slightly.

Step 2: Assemble the Quesadillas

Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper or lightly grease it. Lay out your tortillas on a clean work surface. On one half of each tortilla, sprinkle a layer of shredded cheese, followed by an even portion of the spinach and mushroom mixture. Top with another layer of cheese (the double cheese layer ensures proper sealing and maximum gooeyness). Carefully fold the empty half of the tortilla over the filling, creating a half-moon shape.

Step 3: Bake to Perfection

Transfer the assembled quesadillas to your prepared baking sheet. Lightly brush the tops with olive oil or cooking spray to promote browning. Place the baking sheet in the preheated oven and bake for 10-12 minutes until the tortillas turn golden brown and crispy, and the cheese inside is completely melted. For extra crispiness, carefully flip the quesadillas halfway through baking time. Once done, remove from the oven and let them rest for a minute or two before cutting into wedges.

Tips for Making the Recipe

• Cook out as much moisture from the mushrooms as possible to prevent soggy quesadillas
• Don’t overload the tortillas with filling – a thin, even layer works best for proper cooking
• For extra flavor, add a thin layer of cream cheese or herbed cream cheese spread before adding the other fillings
• Ensure the oven is fully preheated before baking for the crispiest results
• For a quick shortcut, use pre-washed spinach and pre-sliced mushrooms
• If the tortillas are browning too quickly but the cheese isn’t fully melted, lower the oven temperature and cover loosely with foil

How to Serve

Serve these Baked Spinach Mushroom Quesadillas hot from the oven, cut into triangular wedges for easy handling. They pair perfectly with a variety of dipping options – try salsa, guacamole, or sour cream for traditional accompaniments. For a complete meal, serve alongside a simple green salad dressed with vinaigrette or a cup of tomato soup. These quesadillas make an excellent lunch, light dinner, or cut them smaller for appetizers at your next gathering. For an elevated presentation, garnish with fresh cilantro, sliced green onions, or a sprinkle of paprika.

Make Ahead

These quesadillas are perfect for meal prep and can be prepared in several ways ahead of time. The spinach and mushroom filling can be cooked up to 3 days in advance and stored in an airtight container in the refrigerator. For partially prepared quesadillas, assemble them completely, then wrap individually in plastic wrap and refrigerate for up to 24 hours before baking. You can also freeze the assembled (unbaked) quesadillas by placing them on a baking sheet until frozen solid, then transferring to freezer bags where they’ll keep for up to 3 months. Bake frozen quesadillas at 375°F for 15-20 minutes until heated through and crispy.

FAQs

Can I make these quesadillas gluten-free?

Yes, simply substitute the regular flour tortillas with your favorite gluten-free tortillas. Just be aware that some gluten-free tortillas may be less flexible, so handle them carefully when folding. The rest of the ingredients in this recipe are naturally gluten-free, but always check your cheese packaging to ensure there are no additives containing gluten.

How can I make these quesadillas vegan?

These quesadillas can easily be made vegan by substituting the regular cheese with your favorite plant-based cheese alternative that melts well. Brands like Daiya, Violife, or Follow Your Heart work particularly well in quesadillas. Ensure the vegan cheese is well-incorporated with the vegetables for the best melting results.

How do I prevent my quesadillas from getting soggy?

The key to crispy quesadillas is managing moisture. Make sure to cook the mushrooms long enough to evaporate their natural moisture, and thoroughly drain the spinach after wilting. Additionally, allow the filling to cool slightly before assembling to prevent steam from being trapped inside the tortilla. Baking on a preheated baking sheet can also help crisp the bottom of the quesadillas.

Can I use corn tortillas instead of flour tortillas?

While traditional quesadillas often use flour tortillas because they fold easily without breaking, you can use corn tortillas for a different flavor profile. However, corn tortillas are smaller and less flexible, so instead of folding them, use two tortillas to make a sandwich with the filling in between. They may also require a slightly shorter baking time, so keep an eye on them to prevent burning.
