Ingredients

Sweet Potatoes:

  • 3 pounds (1.3kg) sweet potatoes peeled and cut into 2-inch pieces
  • ¼ cup unsweetened oat milk or other nondairy milk
  • 2 tablespoons butter can use vegan, as needed
  • ¾ teaspoon kosher salt
  • ¼ teaspoon freshly ground black pepper
  • ¼ teaspoon ground nutmeg
  • 1/8 teaspoon ground cloves
  • ¼ teaspoon ground cinnamon

Topping:

  • ½ cup (45g) rolled oats
  • ¼ cup (28g) fine almond flour
  • 2 tablespoons (30g) coconut sugar
  • cup (40g) chopped pecans
  • ½ teaspoon kosher salt
  • 1/8 teaspoon ground nutmeg
  • ¼ cup (60ml) melted butter or liquid coconut oil

Instructions

  • Put the sweet potatoes in a large saucepan and cover with water. Bring to a boil and cook until very soft, 20-25 minutes.
  • Preheat the oven to 350 degrees.
  • Drain the sweet potatoes, return to the pan or transfer to a large mixing bowl. Add the oat milk, butter, salt, pepper, nutmeg, cloves and cinnamon. Mash until smooth, with a potato masher or puree with an immersion blender. Scrape the mixture into a 3-quart baking dish and smooth the top.

Notes

Make ahead - Assemble the casserole in the baking dish with the topping or store the topping separate and add just before baking, cover and keep refrigerated up to 1 day ahead of baking.
Storing leftovers - store any leftover healthy sweet potato casserole covered in the baking pan or in separate, airtight containers in the fridge for up to four days.
To reheat - simply rewarm a portion of the casserole in the microwave, or feel free to reheat the entire baking dish if you'd like to warm up more than one serving.
