Hong Kong Egg Tarts

Hong Kong egg tarts are a true bakery classic. With their flaky crusts and silky custard centres, these pastries are a staple at dim sum tables and cha chaan tengs (Hong Kong-style cafés).

Making traditional pastry from scratch can take hours of laminating butter and dough. Fortunately, you can achieve that crisp, multi-layered bite at home by using convenient store-bought puff pastry. Paired with a delicate, glossy custard filling, this recipe brings the beloved taste of Cantonese bakeries right into your own kitchen.

The Fascinating History of Hong Kong Egg Tarts

The story of the Hong Kong egg tart is a delicious example of East-meets-West culinary fusion.

The treat originally evolved in Guangzhou (Canton) during the 1920s. At the time, department store chefs competed fiercely to attract customers by creating weekly “Western-style” culinary specials. Inspired by European custard pastries like British custard tarts and Portuguese pastéis de nata, local chefs adapted the concept using traditional Chinese lard-based flaky pastry and a steamed egg pudding filling.

During the mid-20th century, many Cantonese pastry chefs moved to Hong Kong, bringing the recipe with them. The dessert quickly became a fixture in local tea restaurants and bakeries. Today, you will find two distinct versions across the city: those with a crumbly shortcrust pastry (cookie crust), and those with a delicate, multi-layered laminated dough (puff pastry). This recipe focuses on the puff pastry variety, offering maximum flakiness with minimal fuss.

Q&As on Hong Kong Egg Tarts

1. What is the difference between Hong Kong Egg Tarts and Portuguese Egg Tarts?

Hong Kong egg tarts have a smooth, lightly sweetened custard with a delicate egg flavour. They are usually made with puff pastry or a crumbly shortcrust base, and the custard has a flat, glossy surface. Portuguese egg tarts, also called pastéis de nata, feature flaky laminated pastry and a richer custard made with milk, egg yolks, and sugar. They are baked at a higher temperature, creating distinctive caramelized spots on top. Hong Kong egg tarts are typically softer and more subtle, while Portuguese egg tarts have a richer flavour and toasted, caramelized finish.

2. Why do some Hong Kong Egg Tart recipes use two whole eggs and one egg yolk?

Some recipes use two whole eggs plus one egg yolk to create a richer custard with a deeper yellow colour. The additional yolk adds more fat, which gives the filling a creamier texture and a fuller flavour. It can also make the custard look more golden, especially when using eggs with pale yolks.

This recipe uses three whole eggs for a lighter, more delicate custard with a clean egg flavour. Whole eggs also provide enough egg white to help the custard set properly while keeping the filling soft and silky. Both methods work well, so the choice depends on your preferred colour, richness, and texture.

3. Why should eggs be at room temperature for baking?

Room-temperature eggs blend more easily with the other ingredients, creating a smoother and more uniform mixture. They also combine better with sugar, milk, and melted fats, which helps produce a consistent texture. In custard recipes, room-temperature eggs help the mixture heat evenly in the oven. This can reduce the risk of uneven setting or overcooked patches. For the best results, take the eggs out of the refrigerator about 30 minutes before baking. If you are short on time, place them in a bowl of warm water for a few minutes.

4. Why are Hong Kong Egg Tarts baked at two different temperatures?

The tarts are baked at two temperatures to help both the pastry and custard cook properly. The higher initial temperature encourages the puff pastry to rise, become flaky, and develop a golden colour. Lowering the temperature afterwards allows the custard to set more gently without becoming overcooked or rubbery. The tarts are ready when the pastry is golden and the custard has a slight jiggle in the centre. After baking, letting them rest briefly helps the custard finish setting while keeping its delicate texture.

5. How should leftover egg tarts be stored and reheated?

Let leftover egg tarts cool completely before storing them in an airtight container in the refrigerator for up to three days. For the best texture, reheat them in an oven or air fryer at 300°F (150°C) for five to eight minutes until the pastry is crisp and the custard is gently warmed through. Avoid using the microwave, as it makes the flaky puff pastry soft and soggy. You can also enjoy leftover tarts chilled straight from the fridge for a firmer, refreshing custard treat.
