Ingredients

For the Spinach Filling:

  • 2 tablespoons olive oil

  • 1 small yellow onion, finely chopped

  • 3 cloves garlic, minced

  • 10 oz (280g) fresh spinach (or 1 cup thawed and drained frozen spinach)

  • ½ teaspoon salt

  • ¼ teaspoon ground black pepper

  • ¼ teaspoon crushed red pepper flakes (optional, for heat)

  • ½ teaspoon dried oregano or thyme

  • ¼ teaspoon ground nutmeg (optional, enhances spinach flavor)

  • ½ cup ricotta cheese

  • 1 cup shredded mozzarella cheese

  • ½ cup crumbled feta cheese (or Parmesan if preferred)

  • 1 large egg (for filling)

For Assembly:

  • 2 sheets frozen puff pastry, thawed

  • 1 egg (for egg wash)

  • 1 tablespoon water

  • Extra shredded cheese or sesame seeds (optional, for topping)

Instructions

Step 1: Prepare the Spinach Mixture

  1. Sauté the aromatics
    In a large skillet, heat olive oil over medium heat. Add finely chopped onion and sauté for about 5 minutes, until softened and translucent. Add the minced garlic and stir for 1 more minute until fragrant.

  2. Cook the spinach
    Add fresh spinach (in batches if necessary) to the skillet. Stir and cook for 3–5 minutes until wilted. If using frozen spinach, make sure it is thawed, well-drained, and squeezed dry before adding it to the pan.

  3. Season the mixture
    Stir in salt, black pepper, red pepper flakes, oregano, and a pinch of nutmeg if using. Mix well and allow to cool slightly.

  4. Add the cheeses
    Transfer the spinach mixture to a bowl. Stir in ricotta cheese, mozzarella, and feta. Add one egg and mix until well combined. The filling should be creamy but not watery. If too wet, add a tablespoon of breadcrumbs.

Step 2: Roll Out the Puff Pastry

  1. Preheat the oven
    Set your oven to 400°F (200°C) and line a baking sheet with parchment paper.

  2. Roll the dough
    On a lightly floured surface, unfold or roll out your puff pastry sheets into rectangles roughly 10×12 inches. Keep the second sheet covered until ready to use to prevent drying.

  3. Divide and fill
    Place one puff pastry sheet on the prepared baking sheet. Spread the spinach mixture evenly, leaving about a ½-inch border around the edges. You can either spread the entire filling over one large sheet or divide into smaller pastries (folded triangles, pockets, or mini squares).

Step 3: Seal and Bake

  1. Top with second pastry
    Place the second puff pastry sheet on top. Seal the edges by pressing down with a fork or your fingers. For an extra secure seal, brush the border with egg wash before sealing.

  2. Score and decorate
    Using a sharp knife, lightly score a criss-cross pattern across the top without cutting all the way through. Brush with egg wash (1 egg beaten with 1 tablespoon water) for a shiny golden finish. Sprinkle with sesame seeds or cheese if desired.

  3. Bake to perfection
    Bake for 25–30 minutes or until the pastry is puffed and deeply golden brown. Rotate the pan halfway through for even browning.

  4. Cool and serve
    Let rest for 5 minutes before slicing. Serve warm or at room temperature.

Serving Suggestions

  • As an appetizer: Slice into small squares or strips and serve with a tangy marinara dip or creamy ranch.

  • For brunch: Pair with poached eggs and a fresh citrus salad.

  • As a main course: Serve alongside a simple arugula or cucumber salad for a light, balanced meal.

Tips for Success

1. Drain Your Spinach Well

If using frozen spinach, it’s absolutely essential to squeeze out excess moisture. Too much liquid can lead to a soggy puff pastry. A clean dish towel or paper towels work well for pressing out moisture.

2. Use Cold Pastry

Puff pastry puffs best when cold. If it becomes too soft while you’re working with it, pop it back into the fridge for 10 minutes before assembling.

3. Add Cheese Last

Incorporating cheese into a hot spinach mixture can cause it to melt prematurely and make the filling greasy. Let the spinach mixture cool slightly before adding cheeses.

4. Customize the Cheese

This recipe uses a blend of ricotta, mozzarella, and feta. You can substitute goat cheese, Parmesan, or Gruyère for a more pronounced flavor. Sharp cheddar also adds depth.

5. Don’t Skip the Egg Wash

The egg wash is key to achieving that glossy golden crust. Without it, the pastry may look dull and pale even when fully cooked.

Variations

  • Mushroom & Spinach: Add sautéed mushrooms to the filling for an earthy twist.

  • Sun-Dried Tomato & Basil: Add 2 tablespoons of chopped sun-dried tomatoes and a handful of chopped fresh basil.

  • Ham & Cheese: Add diced cooked ham or prosciutto with Gruyère cheese for a meatier option.

  • Vegan Option: Use vegan puff pastry and swap the cheeses for plant-based alternatives. Replace the egg with a flax egg or dairy-free cream cheese to bind the mixture.

How to Store and Reheat

  • Refrigerator: Store leftovers in an airtight container in the fridge for up to 3 days.

  • Freezer: Wrap cooled slices tightly in foil or plastic wrap and freeze for up to 2 months.

  • Reheating: Reheat in a 350°F (175°C) oven for 10–15 minutes. Avoid microwaving as it may make the pastry soggy.
