Chef Raheem Sealey’s Japanese Sweet Potato Recipe
The Shiso mastermind has elevated the classic side dish to main-course-worthy status with miso butter, parmesan cheese and black sugar.
Japanese Sweet Potato

Serves 1 to 2
Miso Butter
- 2 tablespoons miso
- 4 tablespoons butter
PREPARATION: Combine ingredients and stir until evenly incorporated.
Sweet Potato
- 1 large Japanese sweet potato
- 1 teaspoon Maldon sea salt, divided
- ½ cup miso butter
- 1 tablespoon grated Parmesan cheese
- 1 teaspoon brown sugar
PREPARATION: Bake sweet potato on a baking sheet at 325 degrees for 70 to 90 minutes, until softened and cooked through. When cool enough to handle, split potato in half lengthwise. Season with one-half teaspoon salt, then spread miso butter on potato and top with cheese and sugar. Set oven to broil and return potato to a baking sheet for one minute or until caramelized. Season with remaining salt.
NOTE: Umami salt, flavored with umami-packed dashi, can be used in place of Maldon salt. Sealey substitutes brown sugar with Japanese black sugar (black cane sugar). All may be purchased at specialty retailers.
