This traditional Polish cheesecake, known for its delicate custard-like texture, is a beloved Easter and Sunday-dinner dessert across Poland. Made with tangy farmer's cheese, a buttery shortbread crust, and gently folded egg whites for lift, it bakes slowly in a water bath to stay impossibly silky.

Ingredients
For the buttery shortbread crust
- 1 1/2 cups (190 g) all-purpose flour
- 1/2 cup (115 g) cold unsalted butter, cubed
- 1/3 cup (40 g) powdered sugar
- 1 large egg yolk
- 2 tablespoons cold sour cream
- Pinch of fine salt
For the curd cheese filling
- 2 pounds (900 g) twaróg or farmer's cheese, well-drained
- 1/2 cup (115 g) unsalted butter, softened
- 1 cup (200 g) granulated sugar
- 4 large eggs, separated
- 2 tablespoons potato starch or cornstarch
- 1 teaspoon vanilla extract
- Finely grated zest of 1 lemon
- 1/2 cup (75 g) golden raisins (optional)
Directions
- Make the crust: pulse the flour, butter, powdered sugar, and salt in a food processor until sandy. Add the yolk and sour cream and pulse just until a soft dough forms. Pat into a disc, wrap, and chill for 30 minutes.
- Roll the chilled dough into a 9-inch (23 cm) springform pan, pressing it evenly across the bottom and about 1 1/2 inches up the sides. Chill while you prepare the filling.
- Preheat the oven to 325°F (165°C). Press the twaróg through a fine-mesh sieve or ricer for an ultra-smooth texture; this step is essential for the signature silky filling.
- In a large bowl, beat the softened butter with the granulated sugar until pale and fluffy, about 3 minutes. Beat in the sieved cheese, lemon zest, vanilla, and potato starch until completely smooth.
- Add the egg yolks one at a time, beating well after each. Stir in the raisins if using. In a separate clean bowl, whip the egg whites to soft peaks, then gently fold them into the cheese mixture in three additions, keeping the batter airy.
- Pour the filling into the chilled crust and smooth the top. Place the springform pan in a large roasting pan and pour hot water into the roasting pan to reach halfway up the sides of the springform.
- Bake at 325°F (165°C) for 60 minutes, until the edges are set and the center still has a slight jiggle. Turn off the oven, prop the door open with a wooden spoon, and let the cheesecake cool inside for 1 hour to prevent cracks.
- Remove from the water bath, cool fully on a rack, then chill for at least 6 hours or overnight before slicing with a hot, wiped knife.
Cook’s Notes
- If you can't find twaróg, drain whole-milk ricotta in cheesecloth overnight, or substitute an equal weight of full-fat quark for the closest result.
- Sieving the cheese is non-negotiable for the classic silky texture; skipping this step leaves the filling grainy.
- Always bake the sernik in a water bath to keep the custard gentle and prevent the top from cracking.
- Cooling the cheesecake in the turned-off oven is the traditional trick used in Polish bakeries to avoid sudden shrinking.
- For a glossy finish, brush the chilled cheesecake with a thin layer of apricot jam warmed with a splash of water.
