Full Recipe:
Sweet Potato Base:
- 4 medium Japanese sweet potatoes
- 1 tsp vegetable oil (for roasting)
Custard Crème:
- ⅔ cup granulated sugar
- 3 large egg yolks
- ¼ cup cornstarch
- ¼ tsp salt
- 3 cups whole milk
- 2 tbsp unsalted butter
- 1 tsp vanilla extract
Caramelized Topping:
- 4 tsp caster sugar
Directions:
- Preheat oven to 392℉ (200℃). Wash and dry the sweet potatoes, then rub them lightly with vegetable oil. Wrap in aluminum foil and roast for 1 hour 10 minutes or until fork-tender.
- While the sweet potatoes are roasting, prepare the custard cream. In a saucepan, whisk together sugar, cornstarch, and salt. Gradually add milk, whisking until smooth.
- Heat the mixture over medium heat, stirring constantly until it thickens.
- In a small bowl, lightly beat the egg yolks. Slowly pour about ¼ cup of the hot milk mixture into the yolks while whisking continuously. Then, pour the egg mixture back into the saucepan.
- Cook over medium heat for 2 minutes, stirring continuously, until the custard thickens further. Remove from heat and whisk in butter and vanilla.
- Transfer the custard cream to a bowl, cover with plastic wrap (pressing it onto the surface to prevent a skin from forming), and let cool to room temperature.
- Once the sweet potatoes are cool enough to handle, slice off the tops and carefully scoop out about ⅓ of the flesh, creating a cavity for the custard.
- Fill each sweet potato shell evenly with custard cream.
- Sprinkle 1 teaspoon of caster sugar over each filled sweet potato. Using a kitchen torch, caramelize the sugar until it turns a deep amber and forms a crisp crust.
- Let the caramelized sugar cool and harden slightly before serving. Enjoy!

Japanese Sweet Potato Crème Brûlée: A Fusion of French and Japanese Delights
Japanese Sweet Potato Crème Brûlée is a dessert that perfectly marries the velvety richness of classic French crème brûlée with the natural sweetness and depth of roasted Japanese sweet potatoes. This dish has taken social media by storm, gaining popularity for its unique presentation and comforting flavors. Instead of traditional ramekins, the custard is served directly inside roasted sweet potato shells, making for an elegant yet rustic presentation.
The Viral Popularity of Japanese Sweet Potato Crème Brûlée
This dessert has become a sensation online, with food lovers from around the world sharing their excitement. The combination of smooth custard and caramelized sugar topping creates an irresistible contrast of textures. Its popularity is partly due to the visually stunning presentation—the golden caramel crust cracked open to reveal a creamy, golden-yellow filling nestled inside the deep purple skin of a Japanese sweet potato.
Food enthusiasts and professional chefs alike have embraced this dish, showcasing different variations, including purple-fleshed sweet potatoes and additional flavors like matcha or black sesame. The original inspiration for this dessert is believed to have come from Tokyo-based pastry chefs who experimented with local ingredients to create a dessert that honors both French and Japanese culinary traditions.
Why Japanese Sweet Potatoes Are the Perfect Base
Japanese sweet potatoes, also known as Satsumaimo, are a popular ingredient in Japanese cuisine, often enjoyed roasted, mashed, or even as a base for desserts. They are distinct from regular sweet potatoes due to their denser, sweeter flesh, which has a naturally creamy texture when cooked. Their low moisture content helps them hold their shape well, making them ideal for serving as edible dessert cups.
Unlike standard orange sweet potatoes, Japanese sweet potatoes have a deep purple or reddish skin and pale yellow to golden interior, which deepens in color as they roast. Their natural sweetness intensifies when baked, eliminating the need for excessive added sugars in the custard. This unique flavor profile complements the vanilla-infused custard, creating a delicate balance between richness and natural sweetness.
The Magic Behind the Perfect Crème Brûlée Texture
A key element of any crème brûlée is its silky-smooth custard, which requires careful attention to achieve the perfect texture. The combination of egg yolks, milk, and a touch of cornstarch creates a creamy yet firm consistency. Unlike traditional crème brûlée, which uses heavy cream, this recipe substitutes milk for a lighter, more balanced texture that enhances the roasted sweet potato’s flavor rather than overpowering it.
The slow cooking process allows the custard to develop its signature velvety texture. The key to a perfect crème brûlée is gently heating the mixture while continuously stirring to prevent curdling. Additionally, cooling the custard properly before serving ensures that the flavors meld together beautifully.
The Art of Caramelizing the Sugar Topping
One of the most satisfying aspects of crème brûlée is the crispy, glass-like caramelized sugar topping. Achieving the perfect brûlée effect requires a steady hand and a kitchen torch. The fine layer of caster sugar is evenly spread over the custard before being torched until golden brown, creating a satisfying crack when tapped with a spoon.
If you don’t have a kitchen torch, the caramelization process can be achieved by broiling the dessert under high heat for a few minutes. However, torches are recommended as they allow better control over the level of caramelization, preventing the custard from overheating.
Serving and Presentation: A Feast for the Eyes
The presentation of Japanese Sweet Potato Crème Brûlée sets it apart from traditional desserts. Serving the custard inside the roasted sweet potato shells creates an aesthetic and sustainable approach, as it eliminates the need for ramekins or additional serving dishes. The contrast between the deep purple skin and the golden, caramelized top adds a striking visual appeal that makes this dessert Instagram-worthy.
To enhance the presentation further, the crème brûlée can be garnished with a sprinkle of powdered sugar, fresh berries, or a drizzle of caramel sauce. A scoop of vanilla ice cream or a dollop of whipped cream can also be served alongside for an extra indulgent experience.
Health Benefits of Japanese Sweet Potatoes in Desserts
Japanese sweet potatoes are not only delicious but also packed with nutritional benefits. They are:
- High in fiber, aiding digestion and promoting gut health.
- Rich in antioxidants, particularly beta-carotene, which supports eye health and immunity.
- A great source of complex carbohydrates, providing sustained energy without causing blood sugar spikes.
- Loaded with vitamins and minerals, including Vitamin C, Vitamin B6, and potassium.
Unlike refined desserts that rely heavily on processed sugars, this crème brûlée benefits from the natural sweetness of Japanese sweet potatoes, making it a healthier alternative to many traditional custard-based desserts.
Variations and Customization Ideas
One of the best things about this recipe is its adaptability. Here are some variations to try:
- Matcha Infused: Add a teaspoon of matcha powder to the custard mixture for an earthy green tea twist.
- Black Sesame Delight: Mix in ground black sesame seeds for a nutty depth of flavor.
- Purple Sweet Potato Version: Swap out Japanese sweet potatoes for Okinawan purple sweet potatoes for a vibrant, colorful variation.
- Dairy-Free Alternative: Substitute milk with almond, coconut, or oat milk for a plant-based version.
