Ingredients
For the Filling
- 2 tablespoons olive oil
- 1 small onion, finely chopped
- 2 cloves garlic, minced
- 10 oz (280g) fresh spinach (or frozen, thawed and drained)
- 1 cup crumbled feta cheese
- 1 cup shredded mozzarella cheese
- ¼ cup grated Parmesan cheese
- 1 egg
- 1 teaspoon dried oregano
- ½ teaspoon black pepper
- ¼ teaspoon salt (adjust depending on feta)
- ¼ teaspoon red pepper flakes (optional)
- 1 tablespoon chopped fresh parsley
For the Pastry
- 10 sheets phyllo dough
- ½ cup melted butter (or olive oil)
- 1 egg beaten with 1 tablespoon milk (egg wash)
- Sesame seeds or everything bagel seasoning (optional)
Instructions
Step 1: Prepare the Filling
Heat olive oil in a skillet over medium heat. Add the chopped onion and sauté for about 3–4 minutes until softened. Stir in the garlic and cook for another minute.
Add the spinach and cook until wilted. If using frozen spinach, make sure all excess moisture has been squeezed out before adding.
Remove from heat and allow the mixture to cool slightly.
Mix in the feta, mozzarella, Parmesan, egg, oregano, parsley, salt, black pepper, and red pepper flakes until well combined.
Step 2: Prepare the Phyllo Dough
Lay one sheet of phyllo dough on a clean surface.
Brush lightly with melted butter.
Place another sheet on top and brush again.
Cut the layered sheets lengthwise into three long strips.
Step 3: Fold the Triangles
Place about one tablespoon of filling at the bottom of each strip.
Fold one corner diagonally to create a triangle.
Continue folding upward like folding a flag until reaching the end.
Seal the edge with a little butter.
Repeat until all filling has been used.
Step 4: Bake
Preheat oven to 375°F (190°C).
Arrange triangles on a parchment-lined baking tray.
Brush with egg wash.
Sprinkle sesame seeds or everything seasoning on top.
Bake for 22–28 minutes, or until beautifully golden and crispy.
Cool for 5 minutes before serving.

Frequently Asked Questions
Can I use frozen spinach?
Yes. Thaw it completely and squeeze out as much water as possible before mixing it with the cheeses.
Can I make these ahead of time?
Absolutely. Assemble the triangles, freeze them on a baking tray, then transfer them to freezer bags. Bake directly from frozen, adding 5–8 extra minutes.
Can I air fry them?
Yes. Air fry at 360°F (182°C) for about 10–12 minutes until golden.
What cheese works best?
Feta provides the classic Mediterranean flavor, while mozzarella adds creaminess. Ricotta, goat cheese, or cheddar can also be used.
Why is my phyllo dough breaking?
Phyllo dries out quickly. Keep unused sheets covered with a slightly damp towel while working.
Can I make this recipe gluten-free?
Yes, if you can find gluten-free phyllo pastry. The filling itself is naturally gluten-free.
Can I serve these cold?
They’re best warm, but they also taste delicious at room temperature, making them perfect for picnics and parties.
