Spinach & Cheese Phyllo Triangles

Introduction

Whenever I’m hosting friends or need a make-ahead appetizer, I usually bake these Spinach & Cheese Phyllo Triangles. They’re wonderfully crispy on the outside with a rich, cheesy spinach filling that’s always a crowd-pleaser. Honestly, they look like something from a bakery, but they’re surprisingly easy to make. I often prepare a batch ahead of time and freeze them, so I always have a delicious snack or appetizer ready whenever I need one.

Ingredients

For the Filling

2 tablespoons olive oil
1 small onion, finely diced
2 cloves garlic, minced
10 oz (280g) fresh spinach, chopped (or frozen spinach, thawed and well-drained)
1 cup crumbled feta cheese
½ cup ricotta cheese
½ cup shredded mozzarella cheese
1 large egg
1 teaspoon dried dill or 1 tablespoon fresh dill, chopped
½ teaspoon black pepper
¼ teaspoon salt (optional, as feta is already salty)
¼ teaspoon ground nutmeg (optional)

For the Pastry

10–12 sheets phyllo pastry, thawed
½ cup melted butter or olive oil for brushing

For the Topping

1 egg, beaten (egg wash)
1 tablespoon sesame seeds or poppy seeds (optional)

Step-by-Step Method

Step 1: Prepare the Filling

Heat the olive oil in a skillet over medium heat.

Cook the onion for about 4 minutes until softened, then stir in the garlic and cook for another minute.

Add the chopped spinach and cook until wilted. If using frozen spinach, make sure it has been thoroughly drained before adding it.

Remove the pan from the heat and allow the mixture to cool.

Step 2: Mix the Cheese Filling

In a large bowl, combine the cooled spinach mixture with the feta, ricotta, mozzarella, egg, dill, black pepper, and nutmeg.

Mix until everything is evenly combined.

Step 3: Prepare the Phyllo

Lay one sheet of phyllo pastry on a clean surface and lightly brush it with melted butter.

Place another sheet on top and brush again.

Cut the layered sheets into three long strips.

Step 4: Fill and Fold

Place about 1 tablespoon of filling near one end of each strip.

Fold the pastry over the filling diagonally to create a triangle.

Continue folding, keeping the triangular shape until you reach the end of the strip.

Seal the edge with a little butter.

Repeat with the remaining pastry and filling.

Step 5: Bake

Preheat your oven to 375°F (190°C).

Arrange the triangles on a parchment-lined baking tray.

Brush each one with egg wash and sprinkle with sesame or poppy seeds if desired.

Bake for 20–25 minutes, or until golden brown and crisp.

Step 6: Serve

Allow the triangles to cool for 5 minutes before serving.

Enjoy them warm for the best flaky texture.

Cooking Tips

Keep the phyllo sheets covered with a slightly damp towel while working to prevent them from drying out.
Squeeze as much moisture as possible from the spinach to avoid soggy pastries.
Don’t overfill the triangles or they may burst while baking.
Brush every layer lightly with butter for the flakiest texture.
Freeze the unbaked triangles for quick appetizers whenever needed.

Frequently Asked Questions

1. Can I freeze these phyllo triangles?

Yes! Freeze them unbaked on a baking tray until firm, then transfer them to a freezer bag. Bake directly from frozen, adding 5–8 extra minutes to the baking time.

2. Can I use frozen spinach?

Absolutely. Just thaw it completely and squeeze out as much liquid as possible before mixing it with the cheeses.

3. How do I store leftovers?

Store leftover triangles in an airtight container in the refrigerator for up to 4 days.

4. How do I reheat them?

Reheat in a 350°F (175°C) oven or air fryer for 5–8 minutes to restore their crispy texture. Avoid microwaving, as it can make the pastry soft.

5. Can I add other ingredients to the filling?

Yes! Try adding sautéed mushrooms, caramelized onions, chopped sun-dried tomatoes, fresh herbs, or cooked shredded chicken for delicious variations.
