Instructions

  1. Preheat your oven to 400 degrees F (200 degrees C). Lightly grease a 9 inch tart tin or pie dish.
  2. Roll out the thawed puff pastry on a lightly floured surface to fit your tart tin, about 2 mm thick.
  3. Carefully line the tart tin with the puff pastry, pressing gently into the edges, then trim any excess pastry.
  4. Use a fork to prick holes evenly across the pastry base to prevent it puffing too much.
  5. Place parchment paper over the pastry and fill with baking beans or dried beans to blind bake.
  6. Bake the pastry base for 12 minutes, then remove the parchment and beans and bake for 5 more minutes until lightly golden.
  7. Meanwhile, whisk the eggs, sugar, and vanilla extract in a mixing bowl until smooth and pale.
  8. Sift in the plain flour and whisk again until no lumps remain.
  9. Heat the milk gently in a saucepan until just warm, not boiling. Gradually pour the warm milk into the egg mixture, whisking constantly.
  10. Return the mixture to the saucepan and cook gently over low heat, stirring continuously, until the custard coats the back of a spoon, about 5 to 7 minutes. Do not boil.
  11. Pour the thickened custard into the pre-baked tart shell, filling just below the rim.
  12. Sprinkle the top lightly with ground nutmeg.
  13. Reduce the oven temperature to 350 degrees F (180 degrees C) and bake for 20 minutes, until the custard is set but still slightly wobbly in the center.
  14. Cool the tart in the tin for 15 minutes, then transfer to a wire rack to cool completely before slicing.
  15. Serve slightly warm or at room temperature.

Tips

Equipment Needed

Use a 9 inch tart tin or pie dish, rolling pin, fork, parchment paper, baking beans, mixing bowl, whisk, saucepan, sieve, and wire rack. The baking beans are important because they keep the puff pastry base flat during blind baking.

Ingredient Prep Notes

Keep the puff pastry cool while rolling so it stays flaky and does not become greasy. Warm the milk gently and add it slowly to the eggs while whisking, because rushing this step can curdle the custard.

Oven Note

Start at 400 degrees F to crisp the pastry, then lower to 350 degrees F before baking the filled tart. The custard should be set around the edges with a slight wobble in the center, as it firms while cooling.

Easy Upgrade Ideas

Add lemon zest, orange zest, or vanilla bean paste to the custard for a brighter bakery-style flavor. Serve cooled slices with berries, whipped cream, or a thin caramel drizzle while keeping the tart itself simple.

Frequently Asked Questions

Can I make custard tart ahead?
Yes. Bake and cool the tart fully, then refrigerate it until serving the same day or the next day.
Why did my custard curdle?
The milk or saucepan heat was likely too hot. Warm the milk gently, whisk constantly, and do not let the custard boil.
Do I have to blind bake the puff pastry?
Yes. Blind baking helps the base stay crisp instead of turning soggy once the custard is added.
How do I know the tart is done?
The edges should look set and the center should wobble slightly. It will continue to firm as it cools.

Ingredient Replacements

Shortcrust pastry can replace puff pastry if you prefer a sturdier, less flaky crust. Use a gluten-free pastry sheet and a gluten-free flour blend or half the amount of cornstarch in the custard if you need a gluten-free version.

Whole milk gives the richest custard, but oat milk can work for a dairy-free variation with a softer flavor. Swap nutmeg with cinnamon, cardamom, or lemon zest if you want a different warm finish.

Storage and Reheating

Cool the custard tart completely, then cover and refrigerate it for up to 3 days. Store slices in a single layer when possible so the puff pastry edges do not crush.

Serve chilled or bring slices to room temperature before eating. Avoid freezing this tart because custard can separate and the pastry may soften after thawing.
