Feta and Kale Börek

The sound of filo crackling in the oven always takes me straight back to a rainy Sunday when I decided to use up a bunch of kale that was about to wilt in the fridge. I had never made börek before, but the idea of wrapping greens and cheese in buttery layers felt like something I could figure out. What I didn't expect was how the smell of toasted pastry and warm feta would fill the entire apartment, or how satisfying it would be to pull those golden, shatteringly crisp edges from the pan. My neighbor knocked on the door halfway through baking, drawn by the smell, and ended up staying for lunch. That's when I realized this dish had a kind of magic to it.

I made this for a small dinner party once, and I remember feeling nervous about whether the filo would cooperate. I had heard horror stories about it tearing and drying out, but I kept a damp towel over the stack and worked quickly, and it turned out fine. When I brought the whole golden tart to the table, still warm and fragrant, everyone went quiet for a second before digging in. One friend, who claimed she didn't like kale, went back for a second slice without saying a word. That's the kind of quiet victory that makes you want to cook something again and again.

Ingredients

• Fresh kale (250 g, stems removed, chopped): I learned to remove the thick stems completely because they stay tough no matter how long you cook them, and tearing the leaves by hand gives you more control over the size.
• Onion (1 medium, finely chopped): This adds a gentle sweetness that balances the sharpness of the feta, and cooking it until it's really soft makes all the difference in the final texture.
• Garlic (2 cloves, minced): Fresh garlic gives the filling a warm, aromatic base that dried just can't match.
• Feta cheese (200 g, crumbled): The salty, tangy backbone of the whole dish, and I like to use a block and crumble it myself because pre-crumbled feta tends to be drier.
• Ricotta cheese (100 g): This keeps the filling creamy and prevents it from being too crumbly or dry once baked.
• Filo pastry (8 sheets): Delicate and crisp, filo turns into these beautiful golden layers, and I always keep the unused sheets covered with a damp towel so they don't dry out and crack.
• Eggs (3 large): They bind everything together and give the filling structure so it slices cleanly.
• Whole milk (100 ml): Adds richness and helps the custard-like texture form around the greens and cheese.
• Olive oil (50 ml, plus extra for brushing): I use a good quality olive oil for brushing the filo because it adds flavor, not just crispness.
• Ground black pepper (1/2 tsp): A little warmth and bite that wakes up the creamy filling.
• Nutmeg (1/4 tsp, optional): Just a hint brings out the sweetness in the kale and ricotta without being obvious.
• Fresh dill (1 tbsp, chopped, optional): I love the bright, grassy note it adds, especially if you're serving this in spring or summer.
• Sea salt (1/2 tsp, adjust to taste): Taste your feta first because some brands are much saltier than others, and you might need less than you think.

Instructions

Preheat and Prep:

Set your oven to 180°C (350°F) and lightly grease a 23 cm tart or pie dish with olive oil. This keeps the bottom layer from sticking and makes serving so much easier.

Cook the Greens:

Heat a tablespoon of olive oil in a large skillet over medium heat, then add the chopped onion and cook until it's soft and translucent, about 4 minutes. Toss in the garlic and kale, stirring until the kale wilts down into a dark, glossy pile, about 3 to 5 minutes, then take it off the heat and let it cool while you make the filling.

Mix the Filling:

In a large bowl, whisk together the eggs, milk, and 50 ml olive oil until smooth. Stir in the crumbled feta, ricotta, black pepper, nutmeg, dill, and salt, then fold in the cooled kale mixture until everything is evenly combined.

Layer the Base:

Lay one sheet of filo in the prepared dish, letting the edges hang over the sides, then brush it lightly with olive oil. Repeat with 3 more sheets, brushing each one and rotating them slightly so the whole dish is covered and the layers build up evenly.

Add the Filling:

Spoon the kale and cheese mixture over the filo base, spreading it out gently so it reaches the edges. The filling will settle and firm up as it bakes.

Top and Seal:

Cover the filling with the remaining 4 filo sheets, brushing each with oil and tucking the edges in around the sides to seal the tart. If you like, score the top gently into slices with a sharp knife so it's easier to cut later.

Bake Until Golden:

Slide the dish into the oven and bake for 30 to 35 minutes, or until the pastry is crisp and deeply golden brown. The smell will tell you when it's ready.

Rest and Serve:

Let the börek cool for 10 minutes before slicing. This gives the filling time to set so the slices hold their shape beautifully.

Pin it

There was an afternoon when I made this and forgot to tuck in the edges properly, so they hung over the side of the dish and got almost too dark in the oven. But when I pulled it out, those crispy, nearly burnt bits turned out to be everyone's favorite part. We stood around the kitchen, breaking off the crunchy edges and laughing about how the mistakes sometimes taste the best. It reminded me that cooking doesn't have to be perfect to be wonderful.

Make-Ahead and Storage

You can assemble the whole börek up to a day ahead, cover it tightly with plastic wrap, and keep it in the fridge until you're ready to bake. I've done this for brunch gatherings, and it makes the morning so much calmer. If you have leftovers, store them in an airtight container in the fridge for up to three days, and reheat slices in a hot oven for about 10 minutes to bring back the crispness. Microwaving will make the filo soggy, so resist the temptation even when you're in a hurry.

Swaps and Variations

If kale isn't your thing or you can't find it, spinach or Swiss chard work beautifully and cook down even faster. I've also added a pinch of red pepper flakes to the filling when I wanted a little heat, and it gave the whole thing a gentle kick without overpowering the cheese. You can swap the ricotta for cottage cheese if that's what you have, though the texture will be slightly looser. Fresh herbs like parsley or mint can stand in for the dill, and each one brings its own personality to the dish.

Serving Suggestions

This börek is wonderful on its own, but I love serving it with a simple green salad dressed in lemon and olive oil to cut through the richness. A glass of crisp white wine like Sauvignon Blanc or a dry Riesling pairs perfectly, especially if you're serving this for a relaxed lunch or early dinner. If you're making it for a crowd, slice it into smaller pieces and arrange them on a platter with olives, cherry tomatoes, and yogurt for dipping.

• Serve warm or at room temperature, both are delicious.
• Pair with a tangy yogurt sauce or a squeeze of fresh lemon.
• Store leftovers in the fridge and reheat in the oven to keep the pastry crisp.

Every time I make this, I'm reminded that some of the best meals come from using what you have and trusting the process. I hope this becomes one of those recipes you turn to when you want something that feels special but doesn't ask too much of you.

Recipe FAQs

→ Can I use frozen filo pastry for this börek?

Yes, frozen filo pastry works perfectly. Thaw it in the refrigerator overnight before use, and keep it covered with a damp cloth while working to prevent it from drying out.

→ What can I substitute for kale in this dish?

Spinach, Swiss chard, or even collard greens make excellent substitutes. Adjust the cooking time slightly as spinach wilts faster than kale.

→ How do I prevent the filo pastry from becoming soggy?

Ensure the kale mixture is cooled completely before adding it to the pastry, and brush each filo layer generously with olive oil to create a moisture barrier.

→ Can I make this börek ahead of time?

Yes, assemble the börek up to 24 hours in advance, cover tightly, and refrigerate. Bake just before serving for the best texture and flavor.

→ What type of feta cheese works best?

Greek or Bulgarian feta in brine offers the best flavor and texture. Drain and crumble it well before mixing with the other ingredients.

→ How should I store leftovers?

Store leftover börek in an airtight container in the refrigerator for up to 3 days. Reheat in a 180°C oven for 10-15 minutes to restore crispness.
