Buttery puff pastry, creamy feta, and garlicky spinach come together in these golden, flaky squares that feel special without much effort. They’re perfect for brunch, a party tray, or a cozy snack with soup. You can prep the filling ahead, assemble in minutes, and bake right before guests arrive.

Serve warm and watch them disappear. If you’re building a brunch spread, these pair nicely with a make-ahead egg bake like Make Ahead Savory Brunch Egg Bake or a fresh, bright side such as Greek Pasta Salad With Olives.

Prep Time 15 minutes
Cook Time 20 minutes
Total Time 35 minutes
Servings: 12 servings

Ingredients
  

  • 2 sheets puff pastry, thawed but still cold
  • 10 oz frozen chopped spinach, thawed and well-drained (squeeze out excess water)
  • 1 cup crumbled feta cheese
  • 1/2 cup ricotta or cream cheese (softened)
  • 1 large egg (for the filling)
  • 1 small garlic clove, minced (or 1/2 teaspoon garlic powder)
  • 1/4 teaspoon red pepper flakes (optional)
  • 1/4 teaspoon ground black pepper
  • 1/4 teaspoon salt (taste first—feta can be salty)
  • Zest of 1/2 lemon (optional but brightens flavors)
  • 1 egg, beaten with 1 teaspoon water (for egg wash)
  • 1 tablespoon sesame seeds or everything bagel seasoning (optional, for topping)

Method
 

  1. Prep the pastry: Heat oven to 400°F (200°C). Line 2 baking sheets with parchment. Keep pastry chilled until you’re ready to cut.
  2. Make the filling: In a bowl, mix spinach, feta, ricotta (or cream cheese), 1 egg, garlic, red pepper flakes, black pepper, salt, and lemon zest.Stir until evenly combined.
  3. Cut the pastry: On a lightly floured surface, unfold each pastry sheet. Roll gently to smooth seams. Cut each sheet into 9 equal squares (about 3 inches each) for 18 total squares.
  4. Fill: Spoon about 1 tablespoon of filling into the center of each square.Do not overfill.
  5. Shape options: Open-face squares: Score a small border around the edge and keep filling centered.
  6. Folded triangles: Fold corner to corner and crimp edges with a fork to seal.
  7. Brush and top: Transfer to baking sheets. Brush pastry edges with egg wash. Sprinkle sesame seeds if using.
  8. Bake: Bake 15–20 minutes, until puffed and deep golden.Rotate pans halfway for even browning.
  9. Cool slightly: Let rest 5 minutes. The filling sets and the pastry stays crisp.
  10. Serve: Enjoy warm. Great with a simple salad or as part of a brunch board.

Keeping It Fresh

  • Fridge: Store leftovers in an airtight container for up to 3 days.

    Reheat at 350°F (175°C) for 8–10 minutes to re-crisp.

  • Freezer (unbaked): Assemble, freeze on a tray, then transfer to a bag. Bake from frozen at 400°F, adding 5–8 minutes.
  • Freezer (baked): Cool fully, freeze, and reheat at 350°F until hot and crisp.

Health Benefits

  • Spinach: Packed with iron, vitamin K, folate, and fiber.
  • Feta: Adds protein and calcium with a bold flavor, so you use less.
  • Portion-friendly: Small squares keep serving sizes reasonable while still feeling indulgent.

Pitfalls to Watch Out For

  • Wet spinach: Excess moisture makes pastry soggy. Squeeze spinach until very dry.
  • Warm pastry: Soft pastry won’t puff well.

    Keep dough chilled until baking.

  • Overfilling: Too much filling leaks and prevents rise. Stick to about 1 tablespoon per square.
  • Underbaking: Pale pastry tastes doughy. Bake until deep golden.

Alternatives

  • Cheese swaps: Try goat cheese or shredded mozzarella for a milder bite.
  • Add-ins: Chopped sun-dried tomatoes, caramelized onions, or olives add depth.
  • Dairy-free: Use dairy-free feta and cream cheese; brush with oil instead of egg wash.
  • Breakfast twist: Add crumbled cooked bacon or sausage and serve alongside something sweet like Baked Strawberries And Cream French Toast.
  • Party spread: Offer a second savory option, such as Mediterranean Vegetable Soup, or a fresh spring salad like Strawberry Walnut Spring Salad.

FAQ

Can I use fresh spinach?

Yes.

Sauté about 10–12 ounces of fresh spinach in a little olive oil until wilted, then cool and squeeze very dry. Chop and use as directed.

Do I need to prick the pastry with a fork?

If making open-face squares, lightly score a border and prick the center to control puff and keep the filling in place. For folded triangles, no need.

How do I keep the bottoms from getting soggy?

Use a hot oven, line sheets with parchment, and make sure the filling isn’t watery.

You can also start the pans on a preheated baking steel or inverted sheet to jump-start crisping.

Can I make these ahead?

Assemble and freeze unbaked squares, then bake from frozen. Or mix the filling up to a day in advance and assemble right before baking.

What should I serve with them?

They’re great with a simple green salad or a brunch buffet. For a sweet finish with minimal effort, try Blueberry Greek Yogurt Bites for a cool, light treat.

In Conclusion

Spinach Feta Puff Pastry Squares deliver flaky layers, creamy-savory filling, and an impressive look with hardly any fuss.

I’m Jonah, and design is the lens through which I see everything—even dinner. After a decade sketching interfaces for apps, I found myself sketching suppers instead. Food became my way to balance beauty and simplicity, to make meals that feel as welcoming to the eye as they are to the tongue. I believe a plate can comfort as much as a conversation, and that a busy day deserves a meal that doesn’t just feed you, but invites you to pause, to savor. When I cook, I’m always asking: how can this dish feel like home in both flavor and form?
