Ingredients You’ll Need

For approximately 18 to 24 triangles, depending on the size, you’ll need:

For the Filling

• 400–450 g fresh spinach
• 200 g feta cheese, crumbled
• 1 small onion, finely chopped
• 2 garlic cloves, finely minced
• 2 tablespoons olive oil
• 1 large egg
• 2 tablespoons fresh dill, chopped
• 1 tablespoon fresh parsley, chopped
• ¼ teaspoon black pepper
• A small pinch of nutmeg
• Salt, if needed

For the Pastry

• 8–10 sheets of phyllo pastry
• 4 tablespoons melted butter or olive oil
• Sesame seeds, optional

The feta is usually salty enough to season the filling, so taste before adding additional salt.

Preparing the Spinach

The most important step when making spinach and feta triangles is removing excess moisture from the spinach.

Start by washing fresh spinach thoroughly. Place it in a large pan over medium heat and cook for a few minutes until it wilts.

Transfer the spinach to a colander and allow it to cool enough to handle.

Now squeeze out as much excess water as possible.

This step may seem small, but it makes a major difference. If the spinach remains too wet, the filling can become watery and make the phyllo pastry difficult to crisp.

Once the spinach has been squeezed dry, chop it into smaller pieces.

If you’re using frozen spinach, thaw it completely and squeeze it very well before adding it to the filling.

Making the Spinach and Feta Filling

Heat the olive oil in a skillet over medium heat.

Add the finely chopped onion and cook for several minutes until softened. Add the garlic and cook briefly, stirring so that it doesn’t burn.

Add the prepared spinach and stir everything together.

Cook for another minute or two, then remove the pan from the heat.

Allow the mixture to cool slightly.

Transfer the spinach mixture to a bowl and add the crumbled feta, egg, dill, parsley, black pepper, and a small pinch of nutmeg.

Mix gently until everything is evenly combined.

Taste the mixture before adding salt. Feta can vary considerably in saltiness, so additional salt may not be necessary.

The filling should be flavorful but not wet.

How to Work With Phyllo Pastry

Phyllo pastry is wonderfully crisp but can dry out quickly once exposed to air.

Keep the unused sheets covered with a clean, slightly damp kitchen towel while you’re working.

Don’t make the towel soaking wet, as excessive moisture can make the pastry sticky.

When you’re ready to assemble the triangles, place one sheet of phyllo on a clean work surface and lightly brush it with melted butter or olive oil.

Place another sheet on top and brush it lightly again.

Depending on the thickness of your phyllo, you can use two or three layers for each strip.

How to Fold the Triangles

Cut the layered phyllo into long strips, approximately 7–8 cm wide.

Place a spoonful of the spinach and feta filling near one end of a strip.

Fold one corner diagonally over the filling to create a triangle.

Continue folding the triangle over itself along the length of the strip, much like folding a flag.

Keep the filling enclosed as you work.

When you reach the end of the strip, tuck the final edge underneath the triangle or brush it lightly with butter or oil to help seal it.

Repeat with the remaining pastry and filling.

Don’t overfill the triangles. A moderate amount of filling makes them easier to fold and helps prevent the pastry from splitting.

Baking the Triangles

Preheat your oven to 190°C (375°F).

Arrange the assembled triangles on a baking sheet lined with parchment paper.

Leave a little space between each one so that hot air can circulate around them.

Lightly brush the tops with melted butter or olive oil.

If desired, sprinkle a few sesame seeds over the pastry.

Bake for approximately 20–25 minutes, or until the triangles are puffed and beautifully golden brown.

Keep an eye on them toward the end of the cooking time because phyllo can go from golden to overly dark fairly quickly.

Once baked, remove them from the oven and allow them to cool for several minutes before serving.

How to Get Extra-Crispy Phyllo

If your goal is exceptionally crisp pastry, there are a few simple tricks that can help.

First, don’t make the filling too wet.

Second, avoid using excessive butter or oil between the pastry layers. A thin, even coating is enough.

Third, make sure the oven is fully preheated before the triangles go inside.

Finally, avoid overcrowding the baking tray.

The combination of dry filling, properly layered pastry, and good oven heat produces a wonderfully crisp exterior.

What to Serve With Spinach and Feta Triangles

These triangles are delicious on their own, but a dipping sauce can make them even more enjoyable.

Try serving them with:

• Greek yogurt
• Tzatziki
• Lemon yogurt sauce
• Garlic yogurt dip
• Hummus
• A simple cucumber salad
• Tomato and cucumber salad
• Fresh lemon wedges

For a Mediterranean-inspired meal, serve the triangles alongside roasted vegetables, olives, a fresh salad, and grilled chicken or fish.

A Simple Lemon Yogurt Dip

A cool yogurt dip provides a refreshing contrast to the warm, crispy pastry.

To make one, combine:

• 1 cup plain Greek yogurt
• 1 tablespoon fresh lemon juice
• 1 small garlic clove, finely grated
• 1 tablespoon chopped fresh dill
• A pinch of black pepper

Stir everything together and refrigerate until you’re ready to serve.

You can adjust the lemon and garlic according to taste.

Can You Make Them Ahead?

Yes. These spinach and feta triangles are excellent for preparing ahead of time.

You can assemble them several hours before baking. Place the uncooked triangles on a parchment-lined tray, cover them loosely, and refrigerate until you’re ready to bake.

For longer storage, arrange the unbaked triangles in a single layer and freeze them until solid. Once frozen, transfer them to a suitable freezer container.

They can generally be baked directly from frozen, although they may need a little extra time in the oven.

Avoid thawing frozen phyllo triangles at room temperature if the pastry becomes excessively soft or damp.

Storage and Reheating

If you have leftovers, allow them to cool completely before storing them in an airtight container.

Refrigerate and enjoy within a few days.

For the best texture, reheat them in an oven or air fryer rather than a microwave.

An oven temperature of around 175°C (350°F) works well for reheating. Heat until the pastry is hot and crisp again.

Microwaving is convenient, but it can make phyllo pastry soft.

Easy Variations

Once you’ve mastered the basic recipe, you can customize the filling.

Add More Herbs

Fresh mint can add a bright Mediterranean flavor. You can also experiment with oregano, additional dill, or fresh green onions.

Add Ricotta

For a softer and creamier filling, replace part of the feta with ricotta.

Add Green Onions

Chopped green onions work particularly well with spinach and feta and add a mild savory flavor.

Add a Little Lemon Zest

A small amount of finely grated lemon zest can brighten the filling without making it watery.

Try Different Greens

You can replace part of the spinach with finely chopped kale, Swiss chard, or other sturdy leafy greens.

If using greens with a lot of moisture, cook and drain them thoroughly before adding them to the filling.

Common Mistakes to Avoid

Using Wet Spinach

This is probably the most common problem.

Excess moisture can make the filling watery and prevent the pastry from becoming crisp.

Always squeeze cooked spinach thoroughly.

Leaving Phyllo Exposed

Phyllo dries quickly. Keep unused sheets covered while assembling the triangles.

Overfilling the Pastry

Too much filling can cause the pastry to tear or open during baking.

A small spoonful is usually enough.

Skipping the Oil or Butter

The pastry needs some fat between the layers to achieve that characteristic golden, flaky texture.

Use a light coating rather than soaking the sheets.

Baking at Too Low a Temperature

A properly heated oven helps the pastry become crisp instead of remaining pale and soft.

Nutrition and Portion Tips

Spinach and feta triangles can be part of a balanced meal, particularly when served with vegetables or a fresh salad.

Because feta and pastry can be relatively rich, portion size is worth considering if you’re serving them alongside other substantial dishes.

Adding a colorful salad or roasted vegetables can create a more balanced plate while keeping the meal fresh and satisfying.

Frequently Asked Questions

Can I use frozen spinach?

Yes. Frozen spinach works very well. Thaw it completely and squeeze out as much water as possible before making the filling.

Can I use olive oil instead of butter?

Absolutely. Olive oil works beautifully with the Mediterranean flavors in this recipe and can be brushed between the phyllo layers.

Why are my triangles not crispy?

Excess moisture is usually the main culprit. Make sure the spinach is thoroughly drained and avoid overfilling the pastry. Also make sure your oven is fully preheated.

Can I freeze spinach and feta triangles?

Yes. Freezing them before baking is a convenient option. Arrange them in a single layer until frozen, then transfer them to a suitable freezer container.

Can I make them without eggs?

Yes. The egg helps bind the filling, but you can omit it. The filling may be slightly more crumbly, so avoid overfilling the pastry.

What type of feta is best?

A good-quality feta with a pleasant salty and tangy flavor works well. You can use either a block of feta crumbled by hand or pre-crumbled feta.

Final Thoughts

Crispy spinach and feta triangles are a delicious way to bring Greek-inspired flavors to your kitchen. With flaky phyllo pastry surrounding a savory filling of spinach, feta, herbs, and garlic, they offer a satisfying combination of crisp texture and creamy, flavorful filling.

They’re versatile enough for a casual snack but attractive enough for entertaining. You can prepare them ahead of time, freeze them for later, or serve them fresh from the oven with a cool yogurt dip.

The key to success is simple: keep the spinach filling relatively dry, handle the phyllo gently, and bake until the pastry is deeply golden and crisp.

Once you’ve made them once, you’ll likely find plenty of occasions to make them again—from weekend brunches and family dinners to holiday gatherings and casual afternoon snacks.
