Ingredients
For the Sweet Potatoes
- 7 medium Japanese Sweet Potato
For the Custard Cream
- ⅔ cup Sugar
- 3 Egg Yolk (omega 3)
- ¼ cup Cornstarch
- ¼ tsp Salt
- 3 cup Milk
- 2 tbsp Unsalted Butter
- 1 tsp Vanilla Extract
For Caramelizing
- ¼ cup Sugar
How to Make Japanese Sweet Potato Crème Brûlée
Step 1: Preheat the Oven
Preheat your oven to 392℉ (200℃). Wrap each sweet potato in aluminum foil and place them on a baking sheet. Roast for approximately 1 hour and 10 minutes until tender.
Step 2: Prepare the Custard Cream
While the sweet potatoes are roasting:
1. In a saucepan, combine ⅔ cup sugar, ¼ cup cornstarch, and ¼ tsp salt.
2. Gradually add 3 cups milk, whisking continuously to avoid lumps.
3. Heat over medium heat while whisking until thickened.
Step 3: Combine Egg Yolks with Milk Mixture
- In a small bowl, lightly beat 3 egg yolks.
- Slowly stir about ¼ cup of the hot milk mixture into the egg yolks until fully combined.
- Return this mixture back to the saucepan.
Step 4: Thicken Custard
Continue cooking over medium heat for about 2 minutes or until thickened again. Remove from heat and add in 2 tbsp unsalted butter and 1 tsp vanilla extract, whisking until everything is well combined.
Step 5: Cool the Custard Cream
Transfer the custard cream to a bowl. Cover it with plastic wrap, pressing it directly onto the surface to prevent skin formation. Allow it to cool at room temperature.
Step 6: Prepare Sweet Potatoes
Once roasted sweet potatoes have cooled for about 10 minutes:
1. Cut off the tops of each sweet potato.
2. Scrape out roughly ⅓ of each sweet potato’s flesh.
3. Fill each cavity evenly with custard cream.
Step 7: Caramelize Sugar Topping
Sprinkle about 1 tsp of caster sugar evenly over each filled sweet potato. Using a blowtorch, caramelize the sugar until it turns dark amber and bubbly. Let it harden before serving.

Common Mistakes to Avoid
Many home cooks face challenges when making Japanese Sweet Potato Crème Brûlée. Here are some common mistakes and how to avoid them:
-
Not roasting the sweet potatoes properly – Ensure that the sweet potatoes are wrapped tightly in aluminum foil and roasted until they are tender. This enhances the flavor and texture of your dessert.
-
Skipping the whisking step – Whisking continuously while heating the milk mixture is crucial. This prevents lumps from forming in your custard cream, ensuring a smooth texture.
-
Overcooking the custard – Cooking the custard too long can lead to a grainy texture. Keep an eye on it and remove it from heat as soon as it thickens.
-
Using too much sugar for caramelization – Sprinkling too much sugar on top can lead to uneven caramelization. Use just enough to create a thin layer that will melt and bubble nicely.
-
Not cooling properly – Allowing the custard cream to cool at room temperature before using it is key. This prevents condensation that could make your crème brûlée watery.
-
Ignoring presentation – The visual appeal is important! Make sure to caramelize the sugar evenly for a beautiful finish before serving.
