There’s something comforting and a little magical about quesadillas. They carry the warm familiarity of a grilled sandwich, yet lend themselves beautifully to creative fillings. These Mediterranean Quesadillas with Spinach, Feta, Mozzarella, and Red Onion are a perfect example of this fusion – where Middle Eastern tanginess meets the melty goodness of a classic comfort food.
This dish was born out of a summer trip along the Aegean coast, where the salty breeze from the sea mixes with the scent of grilled cheese and herbs. One warm evening in a small coastal village, a local café served a version of this quesadilla folded like a crepe, its edges crisp and golden from the griddle, filled with creamy feta and bright sautéed greens. That memory now lives on in my kitchen, folded between two tortillas.
This recipe is especially perfect in late spring or summer, when fresh spinach is abundant and sweet red onions are at their peak. It’s a quick, satisfying vegetarian meal that feels a little elevated without any fuss. Whether you’re cooking for yourself, your family, or friends at a backyard gathering, these Mediterranean quesadillas will always deliver.

How to Make Mediterranean Quesadillas with Spinach, Feta, Mozzarella, and Red Onion
Let’s bring the warmth and aroma of the Mediterranean to your table with this easy recipe.
STEP-BY-STEP INSTRUCTIONS:
Step 1: Sauté the Vegetables
In a skillet over medium heat, warm the olive oil. Add the sliced red onion and sauté until soft and slightly caramelized, about 4–5 minutes. Stir in the chopped spinach and oregano, and cook until the spinach wilts down – just another 2–3 minutes. Season with a pinch of salt and pepper, then set aside.
Step 2: Assemble the Quesadillas
Lay out your tortillas on a flat surface. On half of each tortilla, sprinkle a generous layer of mozzarella, then spoon over the warm spinach and onion mixture. Crumble feta cheese on top and fold the tortilla over to create a half-moon shape.

Step 3: Cook Until Golden and Crispy
Heat a large skillet or griddle over medium heat. Carefully place the folded quesadillas in the pan, cooking for 2–3 minutes per side, or until golden brown and the cheese is melted through. You may need to work in batches depending on the size of your skillet.
Step 4: Slice and Serve
Remove from the skillet and let rest for a minute before slicing into wedges. Serve warm with a dollop of Greek yogurt or a drizzle of tahini sauce if desired.
HELPFUL TIPS:
- You can add a sprinkle of sun-dried tomatoes or olives for extra Mediterranean flair.
- If using baby spinach, there’s no need to chop—just toss it right into the pan.
- For extra crispiness, lightly brush the outside of the tortilla with olive oil before grilling.
- These reheat well in a toaster oven or air fryer.
