Print Recipe

A lighter, make-ahead sweet potato casserole that delivers classic creamy-sweet-crunchy comfort without the heavy, over-processed feeling. Roasted sweet potatoes are combined with maple syrup, coconut oil, and warm spices, then topped with a crunchy pecan-oat streusel.

Ingredients

Scale
  • 3 pounds sweet potatoes (about 4 medium), scrubbed
  • 3 tablespoons pure maple syrup
  • 2 tablespoons coconut oil, melted
  • 2 large eggs, room temperature
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon fine sea salt
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon freshly grated nutmeg
  • 1 cup pecans, chopped and lightly toasted
  • 1/2 cup rolled oats
  • 3 tablespoons coconut sugar
  • 2 tablespoons coconut oil, melted (for topping)
  • 1/2 teaspoon ground cinnamon (for topping)

Instructions

  1. Preheat oven to 400°F (200°C). Scrub sweet potatoes, cut each in half lengthwise, and place cut-side down on a parchment-lined baking sheet. Roast for 40-50 minutes until a knife slides through the thickest part with no resistance.
  2. Let potatoes cool for about 10 minutes until handleable. Peel off skins (they should come off easily) and transfer flesh to a large mixing bowl or food processor.
  3. Process or mash sweet potatoes until smooth. If using a food processor, pulse in short bursts to avoid gumminess. If mashing by hand, work until no lumps remain.
  4. Add maple syrup, melted coconut oil, eggs, vanilla extract, salt, cinnamon, and nutmeg to the sweet potatoes. Pulse or stir until just combined. Mixture should be thick, glossy, and fragrant.
  5. In a medium bowl, combine chopped pecans, rolled oats, coconut sugar, and 1/2 teaspoon cinnamon. Pour in melted coconut oil and stir until evenly coated and clumpy.
  6. Spread sweet potato mixture evenly into a greased 9×13-inch baking dish. Sprinkle pecan-oat topping evenly over the surface without pressing down.
  7. If baking immediately, place dish in the 400°F oven and bake for 25-30 minutes until topping is golden brown and edges are bubbly. If making ahead, cover tightly with foil and refrigerate for up to 2 days; add about 10 minutes to bake time when starting from cold.
  8. Let casserole rest for 5-10 minutes before serving to allow it to set and the topping to crisp.

Notes

Roasting sweet potatoes instead of boiling concentrates their natural sweetness and prevents waterlogging. Do not over-process the potatoes to avoid a gluey texture. Toast pecans in a dry skillet for 3 minutes for deeper flavor. Room temperature eggs prevent coconut oil from seizing. The casserole can be assembled up to 2 days ahead and refrigerated, or frozen for up to 3 months. For a vegan version, replace eggs with flax eggs. For a nut-free topping, double the oats and add sunflower seeds.
