Feta and Kale Börek

My neighbor knocked one Sunday morning holding a basket of kale from her garden, way more than I knew what to do with. I stood in my kitchen staring at the pile of dark green leaves, scrolling through ideas, when I remembered a börek my colleague brought to a potluck years ago. The memory of those crackling layers and salty cheese made the decision easy. I pulled out the filo from the freezer and started chopping.

I made this for a small dinner party once, and it disappeared before the main course even hit the table. Everyone kept asking if I had trained in pastry, and I had to laugh because filo does all the work for you. One friend scraped the dish with her fork to get the last cheesy bits stuck to the edges. That is when I knew this recipe was a keeper.

Ingredients

• Fresh kale (250 g): Choose bunches with firm stems and vibrant leaves, then strip away the tough ribs before chopping so the filling stays tender.
• Onion (1 medium): A finely chopped onion melts into the filling and adds a sweet base that balances the salty feta beautifully.
• Garlic (2 cloves): Mince it fresh for a punch of flavor that wakes up the greens without overpowering the cheese.
• Feta cheese (200 g): Crumble it yourself from a block rather than buying pre-crumbled, the texture is creamier and the flavor is sharper.
• Ricotta cheese (100 g): This softens the filling and keeps it moist, preventing the börek from feeling dry or crumbly.
• Filo pastry (8 sheets): Thaw it slowly in the fridge overnight so the sheets don't crack, and keep them covered with a damp towel while you work.
• Eggs (3 large): They bind everything together and give the filling structure so it slices cleanly instead of falling apart.
• Whole milk (100 ml): Adds richness to the custard-like base and helps the filo brown evenly in the oven.
• Olive oil (50 ml plus extra): Brushing each layer with good quality oil is what creates those shatteringly crisp golden sheets.
• Black pepper (1/2 tsp): Freshly ground pepper brings warmth without heat, complementing the nutmeg if you choose to use it.
• Nutmeg (1/4 tsp, optional): A tiny grating adds an unexpected earthiness that makes people wonder what your secret is.
• Fresh dill (1 tbsp, optional): This herb is classic in Turkish börek and lends a bright, grassy note that cuts through the richness.
• Sea salt (1/2 tsp): Taste your filling before adding salt since feta is already quite salty, then adjust to your preference.

Instructions

Prep your oven and dish:

Set your oven to 180°C (350°F) and give your tart dish a light coating of olive oil so the bottom layers release easily after baking. This step also helps the filo crisp up rather than steam.

Cook the greens:

Warm a tablespoon of olive oil in a large skillet, then add the onion and let it soften until it turns translucent and smells sweet, about four minutes. Toss in the garlic and kale, stirring until the leaves wilt down into a dark tangle, then remove from heat and let it cool so the eggs don't scramble later.

Make the filling:

Whisk together eggs, milk, and 50 ml olive oil in a large bowl until smooth, then fold in the crumbled feta, ricotta, pepper, nutmeg, dill, and salt. Stir in the cooled kale mixture and taste it, this is your last chance to adjust seasoning before it goes into the oven.

Layer the base:

Lay one sheet of filo into your prepared dish, letting the edges drape over the sides, then brush it lightly with olive oil. Repeat with three more sheets, brushing each one and rotating them slightly so the overhang is even all around.

Fill the tart:

Spoon the kale and cheese mixture evenly over the filo base, smoothing it gently with the back of your spoon. Try not to press down too hard or you will compress the pastry underneath.

Top and seal:

Cover the filling with the remaining four filo sheets, brushing each one with oil and tucking the edges down into the sides of the dish to seal everything in. If you want neat slices later, use a sharp knife to score the top gently into portions before baking.

Bake until golden:

Slide the dish into the oven and bake for 30 to 35 minutes, watching for the pastry to turn a deep golden brown and puff up slightly. The smell of toasted filo will fill your kitchen and let you know it is almost ready.

Rest and serve:

Let the börek cool in the dish for about ten minutes so the filling sets and the layers stay intact when you cut into it. Slice it into wedges and serve warm or at room temperature.

The first time I brought this to a picnic, I watched someone take a bite and pause mid-chew, eyes wide, before going back for seconds without saying a word. Later she asked me to text her the recipe because her kids refused to eat greens at home. I love that this dish sneaks vegetables past even the pickiest eaters, all because of those buttery, crackling layers.

Choosing Your Greens

Kale works beautifully here, but I have also used spinach when that is what I had on hand, and it wilts down even faster in the skillet. Swiss chard brings a slightly earthier flavor and pretty colored stems if you want something a little different. The key is to cook any green until it is completely wilted and then let it cool so excess moisture evaporates, otherwise your filling will be watery. I learned that the hard way after my first attempt turned the bottom filo layers soggy.

Serving Suggestions

This börek shines as a light lunch with a crisp green salad dressed in lemon and olive oil, or you can slice it into smaller wedges for an appetizer before a bigger meal. I have served it alongside roasted vegetables and hummus for a meatless spread that felt generous and satisfying. A glass of chilled Sauvignon Blanc cuts through the richness of the cheese and makes the whole experience feel a little more special, even on a weeknight.

Storage and Reheating

Leftovers keep well in the fridge for up to three days, wrapped tightly in foil or stored in an airtight container. I actually prefer eating cold slices straight from the fridge the next morning with my coffee, the pastry stays surprisingly crisp. If you want to reheat it, pop it in a 160°C oven for about ten minutes to bring back some of that crunch, microwaving will make it soggy.

• You can freeze unbaked börek tightly wrapped for up to a month, then bake it straight from frozen adding an extra ten minutes to the cooking time.
• For a spicy twist, scatter a pinch of red pepper flakes into the filling before layering the filo.
• If feta feels too salty for your taste, rinse the crumbles briefly under cold water and pat them dry before adding to the mixture.

Every time I pull this out of the oven and hear that first crackle as I cut into it, I feel like I have pulled off something impressive with very little fuss. I hope it becomes one of those recipes you reach for whenever you want to turn simple ingredients into something that feels like a small celebration.

Recipe FAQs

→ Can I use frozen kale instead of fresh?

Yes, frozen kale works well. Thaw completely and squeeze out excess moisture before adding to the filling to prevent a soggy pastry.

→ How do I prevent the filo pastry from drying out?

Keep unused filo sheets covered with a damp towel while working. Brush each layer generously with olive oil to maintain moisture and achieve crispness.

→ Can I prepare this ahead of time?

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

→ What can I substitute for feta cheese?

Try goat cheese for a tangy alternative, or use cottage cheese for a milder flavor. Adjust salt accordingly as feta is quite salty.

→ How should I store leftovers?

Store covered in the refrigerator for up to 3 days. Reheat in a 180°C oven for 10 minutes to restore crispness. Avoid microwaving as it softens the pastry.

→ Can I make this dairy-free?

Substitute vegan feta and ricotta alternatives, and use plant-based milk. The texture and flavor will differ slightly but remain delicious.
