Light Spanish Flan (Caramel Custard)
Why this recipe works
- Smooth custard texture: Gentle baking in a water bath helps the eggs set evenly without turning rubbery.
- Balanced sweetness: The caramel adds depth and slight bitterness, keeping the custard from tasting overly sweet.
- Ideal for preparing ahead: Chilling is part of the method, so the flan can be made in advance and turned out just before serving.

Timing notes
- Chill until fully set: The flan needs enough time in the fridge to firm up properly before unmoulding.
- Turn out just before serving: For the neatest finish, keep the custard in its dish until you are ready to plate it.
Texture tips
- Keep the mixture gentle: Whisk only until the eggs are blended; too much air can leave bubbles and a pitted surface.
- Look for a gentle wobble: Remove the flan when the centre still trembles slightly, as it will continue to set as it cools.
Common mistakes
- Do not take the caramel too far: Once the sugar reaches a deep amber colour, pour it into the dish straight away so it does not become bitter.
- Avoid boiling the milk: Warm the milk until steaming, then add it gradually to the eggs to keep the custard smooth.
Make-ahead tips
- Make it ahead: The baked flan keeps well covered in the fridge for up to 3 days before serving.
- Best after unmoulding: Once turned out, serve within 24 hours for the cleanest texture and presentation.

Ingredients
Instructions
- Heat the oven to 160°C (320°F). Put a kettle of water on to boil, and set a baking dish large enough to hold a 1 litre baking dish or similar on the worktop.
- Put the caster sugar and 60 ml water in a saucepan over medium heat and cook without stirring until the sugar dissolves and turns a deep amber. Swirl the pan as needed for even colouring, then immediately pour the caramel into your baking dish and tilt to coat the base.
- Warm the whole milk in the same saucepan over low heat until steaming but not boiling. Take off the heat and stir in the vanilla extract.
- In a mixing bowl, whisk the eggs just until blended, without incorporating too much air. Slowly whisk in the warm milk in a steady stream.
- Pour the custard into the caramel-lined dish. Set the dish in the larger baking dish and carefully pour in enough hot water to come halfway up the sides of the flan dish.
- Bake for 40 to 55 minutes, until the custard is just set with a gentle wobble in the centre. Remove the flan dish from the water bath and leave to cool to room temperature.
- Chill for at least 2 hours, or until fully cold and set. To serve, run a thin knife around the edge, invert onto a plate, and let the caramel run over the top.
Recipe notes
Tips
- For the smoothest custard, whisk gently and avoid frothing, as bubbles can create a pitted surface.
- If the caramel starts to colour unevenly, lift the pan and swirl rather than stirring, which can encourage crystallisation.
- Food safety: this dessert contains eggs; serve fully chilled and keep refrigerated, and avoid serving to vulnerable groups if you cannot ensure the eggs are from a safe, pasteurised source.
Substitutions
- Replace Vanilla extract with vanilla bean paste for a slightly richer vanilla flavour.
Storage
- Refrigerate up to 3 days
- Keep the flan covered in the fridge and turn out just before serving for the neatest finish. If already turned out, store on a rimmed plate to catch the caramel and serve within 24 hours for best texture.
