Japanese Sweet Potato Crème Brûlée Ingredients
For the Crème Brûlée
• Japanese sweet potatoes (satsumaimo) – a rich and velvety base that enhances the crème brûlée's sweetness.
• Granulated sugar – essential for balancing flavors in your creamy mixture and for the perfect topping.
• Heavy cream – gives your dessert that luxurious, silky texture that melts in your mouth.
• Egg yolks – help achieve that classic crème brûlée smoothness and contributes to its rich flavor.
• Vanilla extract – adds a warm, aromatic note that complements the sweet potatoes beautifully.
For the Topping
• Granulated sugar (for topping) – use this to create a crunchy caramelized crust, elevating your dessert to new heights.
Step‑by‑Step Instructions for Japanese Sweet Potato Crème Brûlée
Step 1: Preheat the Oven
Start by preheating your oven to 325°F (160°C). This temperature is crucial for baking the Japanese Sweet Potato Crème Brûlée evenly. While the oven warms up, gather your ingredients and equipment, including mixing bowls and ramekins, to streamline your preparation.
Step 2: Prepare the Custard Mixture
In a mixing bowl, combine the cooked and mashed Japanese sweet potatoes, granulated sugar, heavy cream, egg yolks, and vanilla extract. Whisk the mixture vigorously for about 2-3 minutes until it reaches a smooth, creamy consistency without any lumps. This step is key to achieving the perfect texture for your crème brûlée.
Step 3: Fill the Ramekins
Carefully pour the sweet potato mixture into your ramekins, filling each about three-quarters full. This allows room for the custard to expand slightly during baking. Place the filled ramekins on a baking tray for easy handling, ensuring a secure grip as you transfer them to the next step.
Step 4: Create a Water Bath
Next, place the baking tray with the ramekins into the oven. Before closing the door, fill the tray with hot water until it reaches halfway up the sides of the ramekins. This water bath helps maintain a gentle cooking temperature, resulting in a creamy Japanese Sweet Potato Crème Brûlée. Bake for 30-35 minutes or until the edges are set but the centers still jiggle slightly.
Step 5: Cool and Chill
Once baked, remove the ramekins from the water bath and allow them to cool at room temperature for about 15 minutes. After cooling, transfer them to the refrigerator and chill for at least 2 hours. This chilling time is essential for allowing the flavors to meld and for the dessert to firm up properly.
Step 6: Caramelize the Sugar Topping
When you’re ready to serve, sprinkle a thin, even layer of granulated sugar over the tops of the chilled ramekins. Using a kitchen torch, gently caramelize the sugar until it turns golden and bubbly, which takes about 1-2 minutes. Keep the torch moving to ensure even caramelization, creating that desirable crunchy topping for your Japanese Sweet Potato Crème Brûlée.

Make Ahead Options
These Japanese Sweet Potato Crème Brûlée are perfect for meal prep enthusiasts! You can prepare the custard mixture up to 24 hours in advance, simply whisk the mashed sweet potatoes, sugar, cream, egg yolks, and vanilla extract, then pour it into ramekins and cover tightly with plastic wrap. Refrigerate until you’re ready to bake, which helps in saving time on busy days. While the baked crème brûlée can be stored in the refrigerator for up to 3 days, be sure to add the sugar topping and caramelize it just before serving to maintain that delightful crunch. This way, you’ll have an elegant dessert that’s just as delicious and ready to impress with minimal last-minute effort!

Japanese Sweet Potato Crème Brûlée Recipe FAQs
How do I choose the right Japanese sweet potatoes?
Absolutely! Look for satsumaimo that are firm and free of blemishes. Opt for those with smooth skin and a slightly sweet aroma. Typically, they should be a deep purple color. Avoid any that have dark spots or feel soft, as these may be past their prime.
How should I store leftover Japanese Sweet Potato Crème Brûlée?
Very good question! To keep your leftover crème brûlée fresh, cover it tightly with plastic wrap and store it in the refrigerator for up to 3 days. This will help maintain its creamy texture. Before serving again, remember to caramelize the sugar topping fresh for the best experience!
Can I freeze Japanese Sweet Potato Crème Brûlée?
Certainly! While freezing is not ideal for crème brûlée, you can freeze the custard base (without the caramelized topping) in airtight containers for up to 1 month. To do this, pour the mixture into freezer-safe containers, leaving space for expansion, and seal tightly. Thaw the custard in the refrigerator overnight before serving.
What should I do if my crème brûlée doesn’t set properly?
If your crème brûlée hasn't set after baking, don't worry! It might need more time in the oven; simply put it back in for an additional 5-10 minutes, checking periodically. Ensure that you’ve created a proper water bath, as this helps regulate heat. If the custard is overly jiggly, that usually means it needs more time to firm up.
Are there any dietary considerations for this recipe?
Great question! This Japanese Sweet Potato Crème Brûlée contains eggs and dairy, making it unsuitable for those with egg or dairy allergies. For a vegan version, you could experiment with egg substitutes like silken tofu combined with a non-dairy cream. Just be aware that the texture might differ slightly!
What’s the best way to caramelize the sugar topping?
To achieve the perfect caramelized topping, sprinkle an even layer of granulated sugar over each ramekin—about a teaspoon should do. Using a kitchen torch, keep the flame moving in a circular motion over the sugar until it melts and turns golden brown, about 1-2 minutes. This ensures an even caramelization and prevents burning. Enjoy this sweet moment!
