Step‑by‑Step Instructions for Japanese Sweet Potato Crème Brûlée
Step 1: Preheat the Oven
Begin by preheating your oven to 325°F (160°C). This ensures that it's the perfect temperature for slow baking, allowing the custard to set beautifully. As the oven warms up, gather your ramekins and baking dish to prepare for the next steps.
Step 2: Boil the Sweet Potatoes
In a medium-sized pot, bring water to a boil and add the diced Japanese sweet potatoes. Let them cook for about 10-15 minutes or until tender. You'll know they are ready when a fork easily pierces through. Once cooked, drain and mash the sweet potatoes until smooth and creamy, making sure there are no lumps.
Step 3: Heat the Cream and Milk
In a saucepan, combine the heavy cream and milk over medium heat. Stir occasionally until the mixture reaches a gentle simmer, which should take about 5 minutes. Once it starts bubbling slightly around the edges, remove it from the heat and allow it to cool for a few minutes to prevent curdling when combined with the egg yolks.
Step 4: Whisk the Egg Yolks
In a mixing bowl, add the egg yolks and the vanilla extract. Using a whisk, blend them vigorously until the mixture is smooth and pale, around 2-3 minutes. This step is important for achieving a creamy texture in your Japanese Sweet Potato Crème Brûlée. Gradually incorporate the warm cream and milk mixture, whisking continuously to avoid cooking the yolks.
Step 5: Combine the Sweet Potatoes
Gently fold the smooth sweet potato mash into the egg mixture until fully combined, ensuring there are no visible streaks. The beautiful orange color of the sweet potatoes will enrich the custard, adding to the visual appeal of your dessert. Once blended, carefully pour the mixture into your prepared ramekins, filling them evenly.
Step 6: Set Up the Water Bath
Place the filled ramekins in a deep baking dish. Slowly fill the baking dish with hot water from the kettle, ensuring the water reaches halfway up the sides of the ramekins. This water bath technique helps the custard cook evenly and prevents it from cracking as it bakes.
Step 7: Bake the Custards
Transfer the baking dish to your preheated oven and bake for about 40-45 minutes. You’ll know the custards are set when the edges look firm but the center has a slight jiggle. Remove them from the oven carefully to avoid splashing the water.
Step 8: Chill the Crème Brûlée
Once baked, remove the ramekins from the water bath and let them cool at room temperature for about 30 minutes. Afterward, cover them with plastic wrap and refrigerate for at least 2 hours. Chilling the Japanese Sweet Potato Crème Brûlée enhances the flavors and helps it achieve the desired creamy texture.
Step 9: Caramelize the Top
When ready to serve, sprinkle a thin layer of granulated sugar evenly over the top of each chilled custard. Using a kitchen torch, carefully caramelize the sugar until it becomes a beautiful golden-brown color, forming that signature crunchy layer. Ensure you move the torch in a circular motion to avoid burning one spot.
Step 10: Serve and Savor
Allow the caramelized sugar to cool for a moment before serving. This creates a delightful contrast in texture with the creamy custard underneath. Present your Japanese Sweet Potato Crème Brûlée with a smile, and get ready to impress your family and friends with this unique and delicious dessert!

Tips for the Best Japanese Sweet Potato Crème Brûlée
-
Choose the Right Sweet Potatoes: Opt for fresh, firm Japanese sweet potatoes for the best flavor and texture. Avoid any with soft spots or blemishes.
-
Temperature Control: Ensure your cream and milk are just simmering before combining them with egg yolks. Too hot can cause curdling, ruining your Japanese Sweet Potato Crème Brûlée.
-
Whisk Gently: When incorporating the sweet potatoes into the egg mixture, fold gently instead of whisking vigorously. This keeps your custard light and creamy.
-
Water Bath Importance: Don’t skip the water bath! It allows for even cooking, preventing cracks. Just make sure the water level is halfway up the sides of the ramekins.
-
Chill Well: Be patient during the chilling step. Allowing the crème brûlée to rest for at least 2 hours—preferably overnight—enhances its texture and flavor.
-
Torching Technique: When caramelizing the sugar, move the kitchen torch in a circular motion to achieve an even, golden crust without burning.
How to Store and Freeze Japanese Sweet Potato Crème Brûlée

Room Temperature: It’s best to avoid leaving the Japanese Sweet Potato Crème Brûlée at room temperature for more than 2 hours to maintain freshness and food safety.
-

Japanese Sweet Potato Crème Brûlée Recipe FAQs
How do I choose the right Japanese sweet potatoes?
Absolutely! When selecting Japanese sweet potatoes, look for ones that are firm with smooth skin. Avoid any that have dark spots or feel soft to the touch, as these can indicate overripeness or spoilage. Fresh sweet potatoes ensure the best flavor and texture for your crème brûlée.
What is the best way to store leftover Japanese Sweet Potato Crème Brûlée?
After enjoying your delightful dessert, be sure to refrigerate any leftovers! Cover the ramekins tightly with plastic wrap and store them in the fridge for up to 3 days. This keeps the custard creamy and delicious while preventing it from absorbing any unwanted odors from your fridge.
Can I freeze Japanese Sweet Potato Crème Brûlée?
Of course! To freeze the crème brûlée, it's best to freeze the unmixed custard before baking. Pour the blended mixture into an airtight container and store it in the freezer for up to 1 month. When you're ready to bake, simply thaw it overnight in the fridge before following the baking instructions. This method can save you time later and still deliver that lovely texture!
I had trouble with my crème brûlée setting. What went wrong?
Very! If your custard didn’t set properly, there could be a couple of reasons. Firstly, ensure your water bath reached halfway up the ramekins and was hot enough during baking, as this prevents uneven cooking. Additionally, make sure not to overbake. The edges should be firm, while the center should retain a slight jiggle when you remove it from the oven. If necessary, you can always use a gentle oven thermometer to verify your temperature settings.
Are there any dietary considerations I should be aware of?
Yes! If you're serving this Japanese Sweet Potato Crème Brûlée to a group, remember it contains dairy and eggs, so be cautious of guests with allergies. If you have a lactose intolerance in the mix, you can try substituting the heavy cream and milk with nut milk or coconut cream—this will alter the flavor slightly but can still yield a delightful dessert. Just know that the texture may be a bit different!
How long does it take to make this dessert?
When planning to create this indulgent treat, keep in mind that the total time is about 1 hour and 30 minutes, with an additional 2 hours for chilling. That said, the hands-on prep is only about 15 minutes, after which you can enjoy some well-deserved relaxation while it bakes and cools. Enjoy the process!
