Description

Flaky spinach puff pastry bites filled with sautéed spinach, feta, and parmesan. An easy, crowd pleasing appetizer for any occasion. 


Ingredients

Scale
  • 2 tablespoons butter
  • 1 medium onion, diced
  • 3 cloves garlic, minced
  • 1 1/2 cups frozen chopped spinach (about 10 ounces), thawed and drained
  • 1/2 cup fresh parsley, finely chopped
  • 1/2 cup feta cheese, crumbled
  • 1/4 cup Parmesan cheese, grated
  • 2 large eggs, divided (one for egg wash)
  • ½ teaspoon salt (or to taste)
  • ¼ teaspoon ground black pepper (or to taste)
  • 1 (10x15-inch) sheet puff pastry, thawed if frozen


Instructions

  1. Preheat oven to 375°F. Grease a 12-cup muffin pan generously with cooking spray or butter. Set aside.
  2. Thaw the spinach completely, then squeeze out as much liquid as possible using a clean kitchen towel or paper towels.
  3. Heat butter in a large saucepan over medium-high heat until bubbly. Add onion, garlic, and spinach. Sauté until most of the moisture evaporates, about 3-5 minutes. Set aside to cool for 5 minutes.
  4. In a large mixing bowl, combine the spinach mixture, parsley, feta, parmesan, one egg, salt, and pepper. Mix until evenly combined. Chill in the fridge for 10 minutes.
  5. Place puff pastry on a clean and lightly floured surface. Cut the 10x15-inch sheet into 12 equal rectangles (about 3 by 4 inches each). You will need to make 3 vertical cuts and 2 horizontal cuts.
  6. Press one pastry rectangle into each cup of the prepared muffin pan. Spoon about 2 tablespoons of filling into each. Fold the four corners toward the center of each and pinch lightly together, leaving some filling visible.
  7. Beat the remaining egg in a small bowl with a fork. Brush the egg wash evenly on top of each sealed puff.
  8. Bake for 25-30 minutes until puffed and golden brown. Cool for 5 minutes.
  9. Loosen each puff with a silicone spatula or knife and remove carefully. Serve warm or at room temperature.

Notes

How to store: Store leftovers in an airtight container in the refrigerator for up to 3 days.

How to reheat: Reheat spinach puff pastry bites in a 350°F oven for 8-10 minutes until warmed through and crisp. For a quicker option, reheat in the air fryer at 350°F for 4-6 minutes, checking halfway, until hot and flaky. Avoid microwaving, as it will soften the puff pastry and make it lose its crisp texture.

How to freeze: Spinach puff pastry bites can be frozen either before or after baking, making them ideal for entertaining and meal prep.

  • To freeze unbaked spinach puffs: Assemble the puffs completely, but do not brush with egg wash. Arrange them in a single layer on a baking sheet and freeze for 1-2 hours, until firm. Transfer to a freezer safe container or zip top bag and freeze for up to 2 months. When ready to bake, place the frozen puffs directly into a greased muffin pan, brush with egg wash, and bake at 375°F for 30-35 minutes, until golden and heated through.
  • To freeze baked spinach puffs: Allow baked puffs to cool completely. Freeze in a single layer on a baking sheet for 1-2 hours, then transfer to a freezer safe container. Freeze for up to 2 months. Reheat from frozen in a 375°F oven for 12-15 minutes, or in the air fryer at 350°F for 6-8 minutes, until hot and crisp.
