Learn how to make flaky, crispy Spinach and Feta Puff Pastry Triangles. This easy step-by-step recipe is perfect for parties, snacks, or quick weeknight dinners!
Introduction
I usually find myself scrambling for a quick, impressive appetizer whenever friends drop by unexpectedly. Honestly, nothing saves the day quite like a sheet of puff pastry and some leftover greens from the fridge. These crispy spinach and feta triangles look like they came straight from a bakery, but I promise they are ridiculously easy to whip up at home. The combination of buttery, flaky layers with salty feta and earthy spinach gets me every single time!
Ingredients
1 sheet puff pastry, thawed
2 cups fresh spinach, chopped (or frozen spinach, thawed and squeezed dry)
1 cup feta cheese, crumbled
1 small onion, finely diced
1 clove garlic, minced
1 tablespoon olive oil
1 large egg, beaten (for egg wash)
Salt and black pepper to taste
Optional: A pinch of sesame seeds or everything bagel seasoning for the top
Step-by-Step Method
Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Sauté the aromatics: Heat the olive oil in a skillet over medium heat. Toss in the diced onion and minced garlic, cooking until soft and fragrant (about 3 minutes).
Add the spinach: Stir in the chopped spinach and cook until wilted and any excess moisture has evaporated. Remove from heat and let it cool down slightly.
Mix the filling: In a medium bowl, combine the cooked spinach mixture with the crumbled feta cheese. Season with black pepper and a touch of salt (keep in mind feta is already quite salty).
Prep the pastry: Roll out your thawed puff pastry sheet on a lightly floured surface. Spread the spinach and feta filling evenly across the pastry sheet, leaving a small border around the edges.
Roll and shape: Roll the pastry up tightly into a log, then slice it into neat triangular portions.
Bake: Arrange the triangles on your prepared baking sheet. Brush the tops generously with the beaten egg wash and sprinkle with sesame seeds if desired. Bake for 20 to 25 minutes until puffed and golden brown.
Cooking Tips
Dry your spinach completely: If your spinach is too wet, the puff pastry will get soggy instead of crispy. Make sure to squeeze out every drop of excess water using a clean kitchen towel.
Keep the pastry cold: Puff pastry relies on cold butter to create those gorgeous flaky layers. If your dough gets too warm and sticky while working with it, pop it back into the fridge for 10 minutes before baking.
Serving Suggestions
I love serving these warm straight out of the oven alongside a bright lemon-tahini dip or a side of marinara sauce. They also make a fantastic addition to a weekend brunch spread next to a fresh garden salad.

Frequently Asked Questions
Can I use frozen spinach instead of fresh?
Yes, absolutely! Just make sure it is completely thawed and you squeeze out all the excess moisture using a paper towel or clean kitchen cloth before mixing it with the cheese.
Can I assemble these ahead of time?
You can assemble the triangles a few hours in advance, place them on the baking sheet, and keep them covered in the refrigerator until you are ready to bake. Brush with the egg wash right before they go into the oven.
What can I substitute for feta cheese?
If you aren’t a fan of feta, goat cheese or ricotta mixed with a little parmesan makes a wonderful alternative that still gives a creamy, savory bite.
Can I freeze these after baking?
Yes, baked leftovers can be frozen. Reheat them in a toaster oven or conventional oven at 350°F for about 5 to 10 minutes to bring back that crispy texture. Avoid the microwave, as it will make the pastry soggy.
Do I need to thaw the puff pastry completely?
It should be thawed enough to unfold without cracking, but it’s best to keep it slightly chilled so the butter doesn’t melt before it hits the hot oven.
