Ingredients
For the Filling
- 1 package (10 oz) frozen chopped spinach, thawed and thoroughly squeezed dry
- 4 oz cream cheese, softened to room temperature
- ½ cup grated Parmesan cheese
- ½ cup crumbled feta cheese (or shredded mozzarella)
- 1 large egg
- 1 teaspoon garlic powder
- ½ teaspoon onion powder
- ½ teaspoon Italian seasoning
- Salt and black pepper to taste
For the Pastry
- 1 box (17.3 oz) frozen puff pastry (2 sheets), thawed overnight in the refrigerator
- 1 egg whisked with 1 teaspoon water (for egg wash)
- Extra Parmesan for sprinkling on top (optional)
- Sesame seeds for garnish (optional)
Instructions
Step 1: Prepare the Spinach
This step is absolutely critical and cannot be rushed. Place the thawed frozen spinach in a clean kitchen towel or several layers of paper towels and squeeze out as much liquid as possible. Excess moisture in the spinach is the number one cause of soggy, wet filling — so squeeze, then squeeze again. The spinach should feel dry and crumbly before it goes into the filling. If using fresh spinach, cook it in a lightly oiled pan with crushed garlic until completely wilted, then chop, cool, and drain thoroughly before using.
Step 2: Make the Cheese Filling
In a medium mixing bowl, combine the softened cream cheese, grated Parmesan, crumbled feta, egg, garlic powder, onion powder, Italian seasoning, salt, and black pepper. Mix everything together until smooth and well combined. Add the squeezed-dry spinach and stir until fully incorporated. Taste the filling and adjust the seasoning as needed — it should taste well-seasoned and savory. Set aside while you prepare the pastry.
Step 3: Prepare the Puff Pastry
Preheat your oven to 400°F (200°C) and line two baking trays with parchment paper. Remove the thawed puff pastry from the refrigerator — it should feel cold but pliable. On a lightly floured surface, gently roll each sheet out just enough to smooth any fold lines. Cut each sheet into 9 equal squares (3 cuts across, 3 cuts down), giving you 18 squares total from both sheets.
Step 4: Fill and Shape the Squares
Place the pastry squares on the prepared baking trays. Spoon approximately 1 tablespoon of the spinach and cheese filling into the center of each square — do not overfill. Brush the edges of each square lightly with the egg wash. Bring all four corners of each square together toward the center and press firmly to seal, or fold each square diagonally into a triangle and crimp the edges with a fork.
Step 5: Apply Egg Wash and Bake
Brush the tops of all the assembled squares generously with the egg wash — this gives them that gorgeous deep golden color. Sprinkle extra Parmesan or sesame seeds on top if desired. Bake for 18 to 22 minutes, or until the pastry is puffed, deep golden brown, and the filling is hot and set. Do not underbake — fully golden pastry delivers that satisfying, irresistible crunch.
Step 6: Cool and Serve
Allow the squares to rest on the tray for at least 5 to 10 minutes before serving — the filling inside is extremely hot straight from the oven. These are wonderful served warm, but equally delicious at room temperature, making them perfect for parties where timing is unpredictable.
Tips for Perfect Results
- Keep the pastry cold until you use it — if it feels soft or greasy, refrigerate for 10 minutes before proceeding
- Squeeze the spinach very well — this is the most critical step for a great texture
- Do not overfill — one tablespoon per square is the right amount
- Seal the edges firmly — press with fingers or crimp with a fork to keep the filling inside
- Use block cream cheese, not the spreadable variety — it holds up better in baked fillings
- Let them rest before eating — the filling stays dangerously hot for several minutes after baking
Variations and Customizations
- Bacon version: Stir crumbled cooked bacon into the filling for a smokier, heartier bite
- Greek style: Use feta as the primary cheese with fresh dill and a squeeze of lemon
- Add mushrooms: Sauté finely diced mushrooms and mix into the filling for an earthy flavor
- Spice it up: Add red chili flakes or a dash of hot sauce
- Three-cheese: Combine cream cheese, ricotta, and mozzarella for an ultra-creamy filling
- Mediterranean twist: Add finely chopped sun-dried tomatoes to the filling
Make-Ahead and Storage
Make ahead: Assemble completely, refrigerate on a tray for up to 24 hours, then brush with egg wash and bake when ready. Freeze unbaked: Freeze assembled squares on a tray until solid, then store in a freezer bag for up to 2 months — bake directly from frozen at 400°F, adding 5 extra minutes. Freeze baked: Cool completely and freeze for up to 2 months; reheat in a 375°F oven for about 10 minutes. Refrigerator: Store leftovers in an airtight container for up to 4 days — always reheat in the oven or toaster oven to restore crispiness.
