Step-by-Step Instructions

Step 1 — Prepare the Vegetables

Thinly slice 8 ounces of cremini or button mushrooms and finely chop one small onion. In a large skillet over medium heat, sauté the onions until translucent, then add the mushrooms. Cook until the mushrooms have released their liquid and it has mostly evaporated, about 8-10 minutes.

Step 2 — Wilt the Spinach

Add 5 ounces of fresh spinach (about 5 packed cups) to the skillet with the cooked mushrooms. Stir continuously until the spinach is completely wilted, which should take only 2-3 minutes. Transfer the entire mixture to a colander and press with a spoon to drain any excess liquid; this prevents soggy quesadillas.

Step 3 — Season the Filling

Return the drained spinach and mushroom mixture to the skillet. Stir in 1 teaspoon of ground cumin, ½ teaspoon of garlic powder, and salt and pepper to taste. Let the filling cool for a few minutes off the heat before adding cheese to prevent it from melting prematurely.

Step 4 — Assemble the Quesadillas

Preheat your oven to 425°F (220°C) and line a large baking sheet with parchment paper. Place four large flour tortillas on the sheet. Divide 1 ½ cups of shredded Monterey Jack or a Mexican cheese blend between them, sprinkling cheese only over half of each tortilla. Top the cheese with the cooled spinach-mushroom filling, then fold the tortillas over to create half-moons.

Step 5 — Bake to Golden Perfection

Lightly spray or brush the tops of the folded Baked Spinach Mushroom Quesadillas with oil. Bake on the middle rack for 8-10 minutes, then carefully flip each one. Bake for another 5-7 minutes until both sides are crisp and golden brown, and the cheese is fully melted.

Step 6 — Rest and Slice

Remove the baking sheet from the oven and let the quesadillas rest for 2-3 minutes. This allows the filling to set slightly, making them easier to cut. Use a sharp knife or pizza cutter to slice each quesadilla into 2 or 3 wedges for serving.

Step 7 — Serve with Dipping Sauces

Serve your Baked Spinach Mushroom Quesadillas immediately while hot and crispy. Classic accompaniments include salsa, guacamole, sour cream, or a quick cilantro-lime crema for dipping.

Healthier Alternatives

These baked spinach mushroom quesadillas are wonderfully adaptable. Here are several practical ingredient swaps to tailor them to your dietary needs without sacrificing flavor.

• Protein Alternative (Chicken or Black Beans) — Swap the mushrooms for shredded rotisserie chicken or rinsed canned black beans for a more substantial, protein-packed filling.
• Lower-Carb Tortilla — Use almond flour or coconut flour tortillas to significantly reduce the carb count while adding a subtle, nutty flavor.
• Dairy-Free Cheese — Opt for a high-quality, meltable vegan cheese shreds to make these spinach mushroom quesadillas completely dairy-free.
• Gluten-Free Base — Simply choose certified gluten-free corn or cassava flour tortillas for a celiac-friendly version.
• Low-Sodium Version — Use no-salt-added canned diced tomatoes, low-sodium cheese, and fresh herbs instead of seasoned salt to control sodium levels.
• Extra Greens — Add chopped kale or Swiss chard along with the spinach to boost the nutrient density and earthy notes.
• Spice Boost — Incorporate a diced jalapeño or a pinch of chipotle powder into the filling for a smoky, spicy kick that complements the mushrooms.
• Lighter Cheese — Substitute part of the cheese with a light sprinkle of nutritional yeast for a cheesy, umami flavor with fewer calories.

Serving Suggestions

• Pair these Baked Spinach Mushroom Quesadillas with a vibrant pico de gallo and a dollop of cool sour cream or creamy avocado crema for a classic, crowd-pleasing combination.
• For a heartier meal, serve alongside a simple black bean soup or a crisp Mexican street corn salad.
• Turn them into a fun appetizer by cutting the baked quesadillas into smaller wedges and serving with a trio of dips: salsa verde, chipotle ranch, and guacamole.
• Perfect for casual gatherings, these baked quesadillas are ideal for game day, a quick family dinner, or a meatless Monday centerpiece.
• Create a beautiful, colorful plate by garnishing with fresh cilantro, thinly sliced radishes, and a lime wedge for squeezing.
• For a complete brunch, serve these Baked Spinach Mushroom Quesadillas with a side of scrambled eggs and fresh fruit.
• Keep leftovers warm for a party by placing the baked quesadillas on a wire rack over a baking sheet in a low oven, which prevents them from getting soggy.

Common Mistakes to Avoid

• Mistake: Using raw spinach, which releases too much water during baking. Fix: Always wilt and thoroughly squeeze the spinach dry before adding it to the filling.
• Mistake: Sautéing mushrooms with other veggies, causing them to steam instead of brown. Fix: Cook mushrooms alone in a hot, dry pan first to drive off moisture and develop deep flavor.
• Mistake: Overloading the quesadilla with filling, leading to a soggy, leaky mess. Fix: Use a moderate, even layer of filling and leave a small border around the edges.
• Mistake: Skipping the baking sheet preheat, resulting in a soft, under-crisped bottom tortilla. Fix: Place your baking sheet in the oven as it preheats for a perfectly crisp start.
• Mistake: Using only one type of cheese that doesn’t melt well. Fix: Blend a melty cheese like Monterey Jack with a flavorful one like sharp cheddar for the best texture and taste.
• Mistake: Cutting the baked spinach mushroom quesadillas immediately after baking, which causes the cheese to ooze out. Fix: Let them rest for 2-3 minutes on a cutting board to allow the filling to set.
• Mistake: Not seasoning the vegetable filling adequately, making it taste bland. Fix: Season each component (mushrooms, spinach) with salt and pepper as you cook them.
• Mistake: Using cold tortillas straight from the package, which can tear easily. Fix: Briefly warm tortillas before assembling to make them more pliable and less likely to crack.
• Mistake: Baking at too low a temperature, yielding a chewy rather than crispy tortilla. Fix: Ensure your oven is fully preheated to a high heat, typically 425°F (220°C), for optimal browning.

Storing Tips

• Fridge: Cool leftovers completely, then store in an airtight container for 3-4 days.
• Freezer: Wrap individual quesadillas tightly in plastic wrap and foil, or place in a freezer bag. Freeze for up to 2 months.
• Reheat: For best texture, reheat in an oven or toaster oven at 375°F until the cheese is melted and the internal temperature reaches 165°F. You can also microwave until hot.

Always let your Baked Spinach Mushroom Quesadillas cool to room temperature before storing to prevent condensation, which can make them soggy.
