Spanakopita Spinach and Feta Triangles

Why You’ll Love This Recipe

Spanakopita spinach and feta triangles are everything you want in a crowd-pleasing appetizer. They have a wonderfully crisp, buttery exterior and a rich, savory filling that balances salty feta, nutty Parmesan, and earthy spinach. They feel elegant enough for entertaining but are simple enough to make at home with store-bought phyllo dough.

Another reason to love this recipe is how convenient it is for planning ahead. The filling can be prepared in advance, and the triangles can be assembled and frozen until you are ready to bake. That makes them especially useful for holidays, gatherings, and meal prep. They also pair beautifully with yogurt mint sauce or tzatziki for a fresh, tangy finish.

Ingredients

(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)

• frozen chopped spinach, thawed

• feta cheese, crumbled

• freshly grated Parmesan cheese

• garlic, minced

• ground nutmeg

• kosher salt

• freshly ground black pepper

• egg, lightly beaten

• frozen phyllo dough, thawed

• butter, melted

• yogurt mint sauce or store-bought tzatziki sauce, optional for serving

Directions

Start by thoroughly draining the thawed spinach. Place it in the center of a kitchen towel or cheesecloth, wrap it tightly, and squeeze out as much liquid as possible. This step is important because excess moisture can make the filling watery and soften the phyllo.

In a medium bowl, combine the drained spinach, crumbled feta, Parmesan, minced garlic, nutmeg, salt, pepper, and lightly beaten egg. Mix until the filling is evenly combined. You can make this filling up to a day in advance and keep it refrigerated until ready to use.

Take the thawed phyllo dough out of the refrigerator and let it sit in its package at room temperature for 15 to 20 minutes. Meanwhile, line two large baking sheets with parchment paper and melt the butter over medium-low heat. Keep the butter warm on low heat so it stays easy to brush.

Unroll the phyllo sheets and keep them covered between two lightly dampened tea towels lined with waxed paper. This helps prevent the delicate dough from drying out while you work. Remove one sheet at a time, always keeping the rest covered.

Lay one sheet of phyllo lengthwise on your work surface and brush it lightly all over with butter. Place a second sheet directly on top and brush that with butter as well. Measure and cut the stacked phyllo into five long vertical strips, each about 6 cm wide.

Place a rounded 1/2 tablespoon of filling at the bottom of each strip. Fold one corner of the phyllo over the filling to create a triangle, then continue folding upward in the same flag-style pattern until you reach the end of the strip. Repeat with the remaining phyllo and filling.

As each triangle is finished, brush both sides lightly with butter and place it on the prepared baking sheets in a single layer. Once all the triangles are assembled, preheat the oven to 375 degrees F and bake for 15 to 17 minutes, or until they are puffed, golden, and crispy. Serve warm with yogurt mint sauce or tzatziki if desired.

Servings and timing

This recipe makes about 40 spanakopita triangles, which is ideal for serving a crowd as an appetizer or party snack.

Servings: 40 triangles

Prep time: 30 minutes

Cook time: 17 minutes

Total time: 47 minutes

Variations

One easy variation is to add fresh herbs to the filling. Dill, parsley, or mint all pair beautifully with spinach and feta and give the triangles a more traditional Mediterranean flavor.

You can also swap the Parmesan for another hard cheese such as pecorino for a sharper taste. For a milder filling, try mixing in a little ricotta with the feta.

If you want extra texture, add finely chopped sautéed onion or scallions to the spinach mixture. A pinch of red pepper flakes can also bring a gentle heat.

For a different shape, the same filling can be layered in a baking dish with sheets of phyllo and baked as a more traditional spanakopita pie instead of folded into individual triangles.

Storage/Reheating

Store leftover baked triangles in an airtight container in the refrigerator for up to 4 days. To keep them from getting soggy, let them cool completely before storing.

For longer storage, freeze the unbaked or baked triangles in a single layer until firm, then transfer them to a freezer-safe container or bag. They can be frozen for up to 2 months.

To reheat, place the triangles in a 350 degrees F oven for about 8 to 12 minutes, or until heated through and crisp again. If reheating from frozen, add a few extra minutes. Avoid microwaving if possible, since it softens the phyllo instead of keeping it crisp.

FAQs

Can I make spanakopita triangles ahead of time?

Yes, these are excellent for making ahead. You can prepare the filling a day in advance or assemble the triangles and refrigerate or freeze them before baking.

Do I need to thaw phyllo dough before using it?

Yes, phyllo dough should be thawed in the refrigerator for several hours or overnight before use. Letting it sit briefly at room temperature also makes it easier to handle.

Why do I need to squeeze the spinach dry?

Removing excess moisture keeps the filling from becoming watery and helps the phyllo bake up crisp instead of soggy.

Can I use fresh spinach instead of frozen?

Yes, fresh spinach can be used, but it should be cooked down first and squeezed very dry before mixing into the filling.

What is the best way to keep phyllo dough from drying out?

Keep the stack covered with lightly dampened towels while you work. Only uncover one sheet at a time.

Can I freeze spanakopita triangles before baking?

Yes, unbaked triangles freeze very well. Arrange them on a tray until frozen solid, then store them in a freezer-safe container and bake straight from frozen.

What sauce goes well with these triangles?

Tzatziki, yogurt mint sauce, or even a simple lemony yogurt dip all work well with the savory spinach and feta filling.

Can I make these triangles vegetarian?

They already are vegetarian, as written, making them a great appetizer option for meat-free gatherings.

Why are my triangles not crispy?

They may need a little more baking time, or the spinach may have held too much moisture. Brushing the phyllo with enough butter also helps create a crisp finish.

Can I serve spanakopita triangles at room temperature?

Yes, they are delicious warm or at room temperature, which makes them perfect for buffets, parties, and packed lunches.

Spanakopita spinach and feta triangles are a timeless appetizer that combines flaky pastry with a rich, savory filling in every bite.
