San Sebastian cheesecake
Instructions
I prepare the ingredients. Eggs measured in grams (130 g = 2-3 medium eggs) for precision — egg quantity matters in this delicate recipe. Cornstarch must be CORN, not potato (potato starch is heavier and produces a slight raw-potato off-aroma). Optional: a few drops natural vanilla paste added before baking. Cream cheese should be at room temperature (take out of fridge 2 hours before). Oven preheats to 220-230 °C with top + bottom heat (no convection).
Cream cheese and sugar combine in a mixing bowl.
I mix gently with a spatula or low-speed mixer — never high-speed (incorporates too much air, ruins the texture).
Cornstarch and lemon juice join.
Eggs add ONE AT A TIME, mixing thoroughly between each. Single-egg-at-a-time prevents the mixture from breaking.
After each egg, the mixture may appear separated/curdled — this is normal. Continued careful mixing brings it back to smooth uniform.
Heavy cream pours into the egg-cheese mixture. I mix gently to integrate.
The entire pan lines with silicone baking paper — must cover bottom AND walls completely. Without parchment, the cheesecake sticks irrecoverably to the pan walls.
Liquid mixture pours into the parchment-lined pan. I tap the pan on the counter to release trapped air bubbles. Into the preheated oven.
During the bake, the cheesecake rises dramatically and cracks appear on top — this is normal. After 30 minutes, check doneness: the top should be deeply browned, the centre should jiggle when the pan moves. 30 minutes is the standard time for this size. Cool first at room temperature, then refrigerate (still in pan) 3-4 hours for full stabilisation.
After full chilling, remove from pan and peel off the parchment paper. The exterior may look "messy" or wrinkled — that's the signature look of a Basque-style cheesecake. The taste compensates spectacularly for the rustic appearance. Cafés worldwide serve a slice on its side to showcase the dramatic dark exterior + creamy white interior contrast. Toppings: chocolate sauce, fresh berries, fruit compote, or just plain — all work.Give it a try, enjoy your meal!
Tips
- 1
THE HIGH HEAT IS NON-NEGOTIABLE. 220-230 °C is intentionally high — this is what creates the "burnt" exterior while keeping the interior tender. Lower temperature (180-200 °C) produces a regular cheesecake with golden top — pleasant but not San Sebastian style. The high heat caramelises the surface sugars dramatically before the centre fully sets. Trust the temperature; the dramatic exterior is the recipe's signature.

THE WOBBLE TEST IS THE DONENESS CUE. The classic mistake is overbaking — once the centre stops jiggling, the cheesecake has gone from silky-tender to firm-cake. The wobble in the centre when removing from oven is desired and necessary. The cheesecake will firm up significantly during cooling and chilling. If unsure, pull at 28 minutes rather than 32 minutes — slight under-bake gives proper Basque texture, slight over-bake loses it.

ROOM-TEMPERATURE CREAM CHEESE IS ESSENTIAL. Cold cream cheese refuses to integrate smoothly with eggs and cream — produces lumpy texture even after extended mixing. The 2-hour room-temperature softening is what allows the smooth silky final texture. If you forget: the microwave defrost setting can warm cream cheese in 15-second bursts (stop before melting). The texture difference between cold-cheese and room-temp-cheese is dramatic.

THE 3-4 HOUR FRIDGE STABILISATION. Step 10's chill time isn't optional — the cheesecake structure is so delicate that warm-cut slices crumble apart. The fridge time lets the protein structure fully set into the silky firm-but-tender consistency. Overnight chilling is even better for clean slicing. Take the cheesecake out 20 minutes before serving for best flavour expression — fridge-cold dulls the flavour notes. For another chocolate-cheesecake variation worth trying, try Chocolate Zebra Cheesecake.
FAQ
Why is it called "San Sebastian"? +
The dessert originates from the city of San Sebastián (Donostia in Basque) in the Basque Country of northern Spain. Specifically, the recipe comes from the restaurant La Viña in San Sebastián's Old Town, where chef Santiago Rivera developed it in the 1990s. The dessert went viral globally after 2019 when food media discovered it, becoming the dominant cheesecake style of the early 2020s. The Basque term "tarta de queso" (cheese tart) is the original name; "San Sebastian cheesecake" and "Basque burnt cheesecake" are international variants.
What cream cheese works best? +
Full-fat cream cheese (Philadelphia is the international standard, "Hochland" in Russian markets, "Almette" or similar full-fat versions) — must be at least 30% fat. Reduced-fat or "spreadable" cream cheese versions don't work — they have too much added water that prevents proper setting. European-style full-fat cream cheeses (mascarpone-style) work but produce slightly richer richer flavour. Avoid: cottage cheese (wrong texture entirely), neufchâtel (too lean), Russian "tvorog" (different product, wrong fat profile).
Why does the cheesecake crack and look "burnt"? +
Both are intentional features, not flaws. The dramatic crack pattern forms because the high heat sets the surface before the interior expands during baking — the expanding interior tears the surface. The "burnt" exterior is deeply caramelised milk solids and sugars, NOT actually burnt (no acrid bitter taste). These features are the recipe's signature; many novice bakers panic and pull the cheesecake too early thinking they've ruined it. Embrace the cracks and the dark exterior — that's San Sebastian-style.
Can I add flavours to the basic recipe? +
Yes — the neutral base accepts modest additions. Best add-ins (mixed in at step 7): 1 tsp vanilla extract or paste (most common), 2 tbsp Bailey's or amaretto liqueur (adult versions), 1 tsp matcha powder (green tea cheesecake), 50 g melted dark chocolate (chocolate San Sebastian), 1 tbsp lemon zest plus 1 extra tbsp lemon juice (citrus-bright), or replace 30 g sugar with 30 g brown sugar (caramel notes). Don't add chunks (chocolate chips, fruit pieces) — they sink and disrupt the texture.
