Cheesy Spinach Puff Pastry Squares Recipe

Prepare the Filling:
- In a medium bowl, combine the chopped spinach, ricotta cheese, shredded mozzarella, grated Parmesan, garlic powder, onion powder, salt, and pepper.
- Mix until all ingredients are well incorporated.
Prepare the Pastry:
- Preheat your oven to 400°F (200°C).
- Line a baking sheet with parchment paper.
- Roll out the thawed puff pastry sheets on a lightly floured surface to smooth out any creases.
Assemble the Pastry Squares:
- Cut each puff pastry sheet into equal squares, about 3 inches on each side.
- Place a spoonful of the spinach and cheese mixture in the center of half of the squares.
- Brush the edges of these squares with beaten egg.
Seal the Pastry:
- Place the remaining squares over the filling-topped squares, pressing the edges to seal.
- Use a fork to crimp the edges and ensure they are sealed well.
Bake the Pastry Squares:
- Place the sealed pastry squares on the prepared baking sheet.
- Brush the tops with the remaining beaten egg for a golden finish.
- Bake in the preheated oven for 15-20 minutes, or until the pastry is puffed and golden brown.
Serve:
- Allow the pastries to cool slightly before serving.
- Serve warm as an appetizer, snack, or side dish.

You can add other fillings like cooked mushrooms, ham, or artichokes for variation.
These pastries can be made ahead of time and reheated in the oven before serving.
