Description

Japanese Sweet Potato Crème Brûlée combines the creamy sophistication of classic French custard with the natural sweetness and nutty flavor of roasted Satsumaimo. Silky, earthy, and topped with a crisp caramelized sugar layer, this elegant fusion dessert is as refined as it is comforting—perfect for holidays, dinner parties, or an indulgent solo treat.


Ingredients

Scale
  • 1 medium Japanese sweet potato (about 250g), roasted and mashed
  • 1½ cups heavy cream (360 ml)
  • 3 large egg yolks
  • ¼ cup brown sugar (50 g), plus more for topping
  • ½ teaspoon vanilla extract
  • Pinch of salt
  • Optional: 1 tablespoon maple syrup for depth, cinnamon or nutmeg for spice

Instructions

  1. Roast the Sweet Potato: Preheat oven to 400°F (200°C). Wrap sweet potato in foil and roast for 45–60 minutes until tender. Cool, peel, and mash until smooth.
  2. Prepare the Custard Base: Heat heavy cream in a saucepan until just simmering. Remove from heat.
  3. Whisk Egg Yolks and Sugar: In a bowl, whisk yolks, brown sugar, and salt until creamy. Mix in mashed sweet potato and vanilla extract.
  4. Temper and Combine: Slowly add a little hot cream into the mixture while whisking, then gradually incorporate the rest.
  5. Strain and Bake: Strain custard through a fine mesh sieve, pour into ramekins, and place them in a water bath. Bake at 325°F (160°C) for 35–40 minutes until set but slightly jiggly.
  6. Chill: Cool to room temperature, then refrigerate for at least 3 hours or overnight.
  7. Brûlée and Serve: Sprinkle brown sugar on top and caramelize with a torch until crisp. Serve immediately.

Notes

  • Roast, don’t boil: Roasting intensifies the flavor and keeps texture smooth.
  • Strain the custard: Guarantees a silky, restaurant-quality texture.
  • Caramelize last-minute: For the perfect crunch before serving.
  • Make ahead: Chill the custard up to 2 days in advance and brûlée before serving.
  • Variations: Add matcha for a green tea twist or coconut cream for a dairy-free option.
