Recipe Notes

  • Be sure to cut the shallots very fine.
  • Use a fine grater to grate the ginger for this recipe. If you don't have a grater, mince finely with a sharp knife.
  • Miso is a Japanese paste made with fermented soybeans, salt and other ingredients that can include rice, barley and seaweed. There is yellow miso, white miso and red miso. Most miso is gluten-free, but it if contains barley it will not be. Check the label.

Here's how to make it: 

  1. Line a baking sheet with parchment and cut your sweet potatoes in half lengthwise. Drizzle the potatoes with olive oil then use your clean hands to generously make sure the flat side is coated. Sprinkle with some salt, turn over on the parchment and place them in the oven. Bake in a preheated 425-degree F oven for about 40 minutes, or until golden brown on the flat side.
  2. While the potatoes are cooking make the topping by placing a frying pan on the cooktop on medium-low heat. Add the 1/4 cup coconut oil (or what ever fat you are choosing) and the shallots.
  3. Cook for about 6 to 8 minutes, or until the shallots are golden brown. Add the ginger and stir. Cook for 3 to 4 minutes.
  4. Add the miso and to combine use a fork to press it into the shallot mixture. This won’t be a creamy sauce so don’t worry if its a bit chunky. Sauté the miso with the shallots for another 2 minutes, or until everything looks nice and crispy. Remove the pan from heat.
  5. When the sweet potatoes are nice and brown on the underside and tender when you insert a fork remove them, use a spoon to carve into them from the flat side, making cuts about 1/2 inch apart. Then keeping the flat size up return them to the oven for 3 more minutes.
  6. While the potatoes are in the oven for the last 2 minutes, reheat the shallots on medium. Remove the potatoes, spoon the shallot mixture over the top.
  7. Sprinkle with green onions and a bit of salt and enjoy!
