Step-by-Step Instructions

1. Sauté the vegetables

Start by cooking the red onion in olive oil with a pinch of salt until translucent. Add the sliced cremini mushrooms and cook until they become tender and golden. Add the spinach in batches, allowing it to wilt before adding more. Continue cooking until the excess moisture has evaporated.

Finish the vegetable mixture with salt, pepper, and fresh lime juice, then remove it from the heat.

2. Assemble the quesadillas

Sprinkle the cheese over half of each tortilla. Add the mushroom and spinach mixture, followed by the sliced avocado. Finish with more cheese, then fold the tortillas over the filling.

3. Cook until golden and crispy

Heat a skillet over medium heat and cook the quesadillas until the bottoms are golden brown. Carefully flip them and continue cooking until the other side is crisp and the cheese is melted.

4. Finish with extra crispy cheese

Follow the recipe card’s instructions for adding the remaining cheese to the outside of the quesadillas. Let it melt and crisp before giving the quesadillas their final flip.

5. Slice and serve

Transfer the cooked quesadillas to a cutting board and let them cool slightly. Cut each into three triangles and serve warm with red salsa.

Expert Tips

• Cook the mushrooms until golden: Give them enough time to release their moisture and develop a deeper, savory flavor.
• Don’t rush the spinach: Add it gradually so it wilts evenly and excess moisture can evaporate.
• Keep the heat at medium: Cooking too quickly can brown the tortillas before the cheese has a chance to melt.
• Use a sturdy spatula: The avocado and vegetable filling can make the quesadillas delicate when you’re flipping them.
• Let them cool briefly before slicing: A short rest helps the melted cheese settle and makes them easier to cut.
• For extra crispiness: Follow the recipe’s method of adding cheese to the outside during cooking for those delicious crispy cheese edges.

Recipe Variations

Make Them Dairy-Free

Use a plant-based cheese that melts well in place of the Jack or cheddar.

Use Different Tortillas

If you don’t have whole wheat tortillas, regular flour tortillas or sturdy gluten-free tortillas can work well.

Add More Vegetables

Bell peppers, zucchini, or corn can be added to the filling. Sauté them thoroughly first so they don’t add too much moisture.

Change the Cheese

Try different melting cheeses to create a slightly different flavor while keeping the quesadillas gooey and satisfying.

Add Some Heat

For a spicier version, serve the finished quesadillas with your favorite spicy salsa or add a little heat to the vegetable filling.

Storage & Reheating

For the best texture, these quesadillas are best enjoyed fresh while the tortillas are crisp and the cheese is melted.

If you have leftovers, allow them to cool completely before storing them in an airtight container in the refrigerator.

To reheat, warm them in a skillet over medium heat until heated through and crisp again. A skillet is preferable to the microwave because it helps bring back the crispy tortilla texture.

If preparing ahead, the mushroom and spinach filling can be sautéed the day before and refrigerated. Assemble and cook the quesadillas when you’re ready to serve.

Serving Suggestions

Serve these quesadillas warm with jarred red salsa for an easy, flavorful finish.

They also pair well with:

• A simple green salad
• Fresh tomato salsa
• Guacamole
• Extra avocado
• A squeeze of fresh lime
• Your favorite Mexican-inspired side dishes

For a quick weeknight meal, serve two or three quesadilla triangles alongside salsa and a fresh salad.

1. Can I substitute the cheese for a dairy-free option?

Absolutely! You can use a plant-based cheese that melts well, like vegan mozzarella, to keep it creamy without the dairy. Just make sure it melts properly!

2. Can I prepare the filling ahead of time?

Yes! You can sauté the mushrooms and spinach the day before and store them in the fridge. This way, when you’re ready to make the quesadillas, you can just assemble and cook them in minutes.

3. What if I don’t have whole wheat tortillas?

No problem! You can easily swap in regular flour tortillas or even gluten-free ones if needed. Just make sure they’re sturdy enough to hold the fillings.

4. How do I make sure the quesadillas are extra crispy?

To get that perfect crunch, press down gently on the quesadillas while they cook and flip them carefully to ensure both sides are golden. You can even add a little extra cheese on the outside for an added crispy edge!

5. Can I add more vegetables to the filling?

Definitely! Feel free to toss in some bell peppers, zucchini, or even corn. Just be sure to sauté them well so they don’t release too much moisture into the quesadillas.

Ingredients

• 1 tbsp olive oil

• ½ small lime, juiced
• 2 ½ cups shredded Jack or cheddar cheese, divided

• 4 medium whole wheat tortillas
• Jarred red salsa, for serving

Instructions

• Sauté the Vegetables:

  Heat the olive oil in a large skillet over medium heat.

  Add the chopped red onion and a pinch of salt, stirring occasionally until the onions become translucent.

  Stir in the sliced mushrooms and cook until they soften and develop a golden color (about 6 minutes).

  Add half of the spinach, letting it wilt slightly before adding the rest.

  Continue cooking until the spinach is fully wilted and any excess moisture has evaporated (about 2–3 minutes).

  Season with salt, pepper, and a splash of lime juice, then remove from heat.
• Assemble the Quesadillas:

  Sprinkle 1 cup of shredded cheese evenly across half of each tortilla.

  Distribute the spinach and mushroom mixture over the cheese.

  Layer the avocado slices on top, then sprinkle the remaining 1 cup of cheese over the filling.

  Fold the empty side of the tortilla over the toppings, pressing gently to seal.
• Cook the Quesadillas:

  Heat a medium or large skillet (preferably cast iron) over medium heat.

  Place one or two quesadillas in the pan at a time, cooking for a few minutes until the bottom is golden brown.

  Flip carefully with a spatula and immediately sprinkle some of the remaining cheese over the hot, crispy side.

  Let it melt as the other side cooks for another few minutes.

  Flip again to let the cheese crisp up for a final minute before removing from heat.
• Serve:

  Transfer the cooked quesadillas to a cutting board and allow them to cool slightly.

  Slice each quesadilla into three triangles using a sharp knife or pizza cutter.

  Serve warm with red salsa on the side.
