Ingredients You’ll Need
Getting the ingredients right is key to nailing this Japanese Sweet Potato Crème Brûlée Recipe. You’ll find that each component plays an important role, creating a balance of flavor, texture, and that delicious caramelized top we all love.
- Japanese sweet potato (1 cup): Use satsumaimo for its natural sweetness and creamy texture that blends beautifully into the custard.
- Heavy cream (1 1/2 cups): Adds that luscious, rich feel that defines classic crème brûlée.
- Whole milk (1/2 cup): Lightens the cream slightly for a perfect custard texture.
- Granulated sugar (1/3 cup, plus extra): Sweetens the custard and caramelizes beautifully on top.
- Large egg yolks (4): Provide the structure and silkiness to the custard.
- Vanilla extract (1 teaspoon): Adds warmth and depth to the sweet potato’s natural flavors.
- Pinch of salt: Enhances overall flavor by balancing the sweetness.
How to Make Japanese Sweet Potato Crème Brûlée Recipe
Step 1: Warm the Cream and Milk
Begin by gently heating the heavy cream and milk over medium heat until just warm—warm enough to infuse flavors but not so hot that it boils. This step is crucial because adding warm dairy to the egg yolks prevents curdling and helps you achieve that silky custard texture.
Step 2: Whisk Egg Yolks, Sugar, Vanilla, and Salt
While the cream mixture warms, whisk together your egg yolks, granulated sugar, vanilla extract, and a pinch of salt until the mixture is smooth and slightly pale. This is the base of your custard, so take your time to make it silky and well-blended.
Step 3: Temper the Egg Mixture
Slowly pour the warm cream and milk mixture into the egg yolks while whisking continuously. This gradual mixing keeps the eggs from cooking too quickly and turning into scrambled bits, ensuring a smooth custard.
Step 4: Blend in the Mashed Japanese Sweet Potato
Next, stir in the mashed Japanese sweet potato until the custard is a uniform creamy blend. For an ultra-smooth texture, strain the custard through a fine mesh sieve, freeing it of any lumps and giving it that elegant finish.
Step 5: Bake in a Water Bath
Divide the custard evenly into ramekins and place them in a baking dish. Pour hot water into the dish to come halfway up the sides of the ramekins. This water bath ensures a gentle, even heat that prevents cracking and creates that perfect creamy set. Bake at 325°F (160°C) for 35 to 40 minutes until slightly jiggly but mostly set.
Step 6: Chill Thoroughly
Once baked, let the ramekins cool to room temperature before refrigerating for at least two hours. This chilling solidifies the custard and melds all those amazing flavors together.
Step 7: Caramelize the Tops
Just before serving, sprinkle about one teaspoon of granulated sugar over the surface of each custard. Use a kitchen torch to caramelize the sugar until it’s golden and crisp. Let it rest for a minute or two to harden, then dig in!
How to Serve Japanese Sweet Potato Crème Brûlée Recipe
Garnishes
While the caramelized sugar top is classic, you can elevate your serving with a few thoughtful garnishes. A small sprinkle of toasted sesame seeds or a few fresh mint leaves add a pop of flavor and color. For an autumn vibe, a light dusting of cinnamon or a tiny candied ginger piece pairs beautifully with the sweet potato custard.
Side Dishes
This dessert shines as the grand finale after hearty meals. Because of its rich but gentle sweetness, it pairs wonderfully with light fruit salads or a tangy citrus sorbet. These sides help cleanse your palate and complement the custard’s luscious texture without overwhelming your taste buds.
Creative Ways to Present
Try serving the Japanese Sweet Potato Crème Brûlée Recipe in clear glass ramekins or small mason jars for a modern twist. You can also experiment by layering the custard with a thin graham cracker or almond cookie crust at the bottom for added texture. It makes every bite exciting and adds a subtle crunch underneath that caramelized top.
Make Ahead and Storage
Storing Leftovers
Leftover custard can be covered tightly with plastic wrap and kept refrigerated for up to three days. It might lose a bit of its fresh crisp sugar topping once refrigerated, but the custard itself remains wonderfully creamy and flavorful.
Freezing
Freezing is not recommended for this dessert. The custard may separate and develop an icy texture, which compromises its smoothness and rich flavor. It’s best enjoyed fresh within a few days of preparation.
Reheating
Since crème brûlée is traditionally served chilled, reheating is not necessary. If you prefer to serve it slightly warmer, gently bring it to room temperature before torching the sugar top. Avoid microwaving as it can curdle the custard or melt the caramelized sugar unevenly.
FAQs
Can I use a different type of sweet potato for this recipe?
While you certainly can, satsumaimo Japanese sweet potatoes have a unique sweetness and creamy texture that browsers really well into the custard, giving this dessert its distinctive flavor. Other sweet potatoes might yield a slightly different taste and texture.
Is the kitchen torch necessary for caramelizing the sugar?
A kitchen torch is ideal for getting the perfect caramelized, crisp topping. However, if you don’t have one, you can try placing the sugared custards under a very hot broiler for a short time, watching carefully to avoid burning.
Can I prepare the custard base in advance?
Absolutely! The custard mixture can be made ahead, stored in the refrigerator, and baked fresh when you’re ready to serve. Just make sure to stir it well before baking and adjust baking time if the mixture is colder.
What does the pinch of salt do in this recipe?
Salt enhances the natural sweetness of the Japanese sweet potato and balances the custard’s richness. Without it, the dessert might taste overly sweet or flat.
Can I add other spices to the custard?
Yes! For fall-inspired variations, try infusing the cream with cinnamon sticks, fresh ginger, or star anise as you warm it. Just strain these out before mixing with eggs. It adds lovely layers of flavor to your Japanese Sweet Potato Crème Brûlée Recipe.

Ingredients
Sweet Potato Custard
- 1 cup Japanese sweet potato (such as satsumaimo), peeled, cooked, and mashed
- 1 1/2 cups heavy cream
- 1/2 cup whole milk
- 1/3 cup granulated sugar (plus extra for topping)
- 4 large egg yolks
- 1 teaspoon vanilla extract
- Pinch of salt
Instructions
- Preheat Oven and Prepare Water Bath: Preheat your oven to 325°F (160°C). Arrange 4 ramekins in a baking dish suitable for a water bath.
- Heat Cream and Milk: In a small saucepan, warm the heavy cream and whole milk over medium heat until hot but not boiling, then remove from heat.
- Mix Egg Yolks and Sugar: In a mixing bowl, whisk together the egg yolks, granulated sugar, vanilla extract, and a pinch of salt until smooth and slightly pale.
- Combine Heated Dairy with Eggs: Slowly pour the warm cream mixture into the egg mixture while whisking continuously to avoid curdling the eggs.
- Add Mashed Sweet Potato: Stir the prepared mashed Japanese sweet potato into the custard mixture until fully incorporated and smooth.
- Strain the Custard: For an ultra-smooth texture, strain the custard through a fine mesh sieve into a clean bowl to remove any lumps.
- Pour and Bake: Divide the custard evenly among the ramekins. Pour hot water into the baking dish until it reaches halfway up the sides of the ramekins. Bake for 35 to 40 minutes, or until custards are just set with a slight jiggle in the center.

- Serve: Let the brûlée sit for 1 to 2 minutes after caramelizing, then serve and enjoy the balance of creamy custard with a crisp caramelized top.
Notes
- Use satsumaimo for its naturally sweet, nutty flavor and striking purple skin with yellow flesh.
- For added flavor complexity, you can infuse the cream with a cinnamon stick or fresh ginger piece before mixing with the eggs.
- If you don’t have a kitchen torch, you can briefly broil the sugar topping in the oven, keeping a close watch to prevent burning.
- Make sure the water bath water is hot to help the custards cook evenly and gently.
