Roasted Japanese Sweet Potatoes

Not everyone knows about Japanese sweet potatoes. I make it a personal mission to inform everyone I meet how good they are because I’m a humanitarian. I love how they taste roasted in ghee, a kind of clarified butter that removes the lactose and casein, which can be problematic for some. Ghee provides a delicious caramelized flavor; however, if you’re vegan, simply substitute for coconut oil. It has a comparably high smoke point.

  • Japanese sweet potatoes (1 per person)
  • organic, grass-fed ghee (1 tsp per sweet potato)
  • sea salt
  • freshly ground pepper
  • dried rosemary (1/4 tsp per potato, optional – turmeric is another great optional seasoning)


  • Preheat the oven to 425 F.
  • Give the sweet potatoes a good scrub. Slice into 1/2 inch rounds, cutting off the ends entirely. Another cutting option is to make them into wedges, like fries. Arrange on a baking sheet lined with parchment paper or silicone mat.
  • Melt the ghee either in the preheating oven or microwave. Pour onto the potatoes, using a brush to distribute evenly.
  • Season generously with sea salt, ground pepper to taste and dried rosemary or turmeric if you’re using it. Roast for 20-25 minutes, until a knife slides through the center easily, and they’re just starting to brown.
  • Serve warm. I like mine with a side of Dijon mustard.
