Ingredients Breakdown

Serving Size

Makes 4 large quesadillas.

Tortillas

• 4 large flour tortillas (10-inch burrito size)

Filling

• 1 cup fresh spinach, chopped
• 1/2 cup crumbled feta cheese (preferably crumbled from a block)
• 1/2 cup shredded mozzarella cheese
• 1/4 red onion, thinly sliced
• 1 teaspoon dried oregano (preferably Greek oregano)
• Salt and freshly ground black pepper to taste

Cooking Oil

• 2 tablespoons olive oil, divided

Each ingredient is designed to complement the others: spinach provides freshness and nutrition, feta adds tangy saltiness, mozzarella creates creamy meltiness, and caramelized onions add natural sweetness.

Tools & Equipment Needed

• Large 12-inch skillet
• Spatula
• Cutting board
• Sharp knife
• Paper towels

A wide skillet ensures even browning and enough space to cook the quesadillas without overcrowding.

Step-by-Step Instructions

Step 1: Sauté the Onions

Heat 1 tablespoon of olive oil in a large 12-inch skillet over medium heat (around 325–350°F if using an electric stovetop). Add the sliced red onion and cook for 3–4 minutes, stirring occasionally, until softened and translucent.

Step 2: Wilt the Spinach

Add the chopped spinach, dried oregano, salt, and pepper to the skillet. Cook for 2–3 minutes, stirring frequently, until the spinach has completely wilted and darkened. Drain excess liquid if needed to prevent soggy quesadillas. Remove from heat and let cool slightly.

Step 3: Assemble the Quesadillas

Lay the flour tortillas on a clean work surface. Sprinkle mozzarella evenly over one half of each tortilla, leaving a half-inch border. Divide the spinach and onion mixture evenly over the mozzarella, then top with crumbled feta. Use roughly 1/3 to 1/2 cup filling per quesadilla. Fold the empty half of the tortilla over the filling to form a half-moon shape, pressing gently to seal.

Step 4: Cook the Quesadillas

Wipe out the skillet with a paper towel. Heat the remaining 1 tablespoon of olive oil over medium heat until shimmering. Place one or two quesadillas in the skillet (don’t overcrowd) and cook for 3–4 minutes per side, pressing gently with a spatula for even browning. Cook until the exterior is deep golden and cheese is fully melted.

Step 5: Rest and Serve

Remove cooked quesadillas from the skillet and let them rest for 1–2 minutes before cutting into wedges. Repeat with remaining quesadillas, adding more oil if needed. Serve immediately.

Ingredient Spotlight

Spinach

Fresh spinach provides vitamins A, C, K, iron, and fiber. Sautéing it removes excess moisture and intensifies flavor without losing nutrients.

Crumbled block feta offers tang and creaminess. Crumbling it yourself improves texture and prevents clumping. Choose a quality Greek feta for the best flavor.

Pro Cooking Tips

• Press quesadillas gently while cooking for even browning and melted cheese.
• Drain any excess liquid from spinach to avoid soggy quesadillas.
