Stop juggling oven space during holiday meals. This Crockpot Sweet Potato Casserole delivers a creamy, spiced base and a crisp pecan topping using simple steps. It is the easy, make-ahead side dish that frees up your oven for the main event.

Ingredients

Scale
  • 3 pounds sweet potatoes, peeled and cut into 1-inch chunks
  • 1/2 cup milk
  • 1/2 cup (1 stick) unsalted butter, melted, plus 2 tablespoons for topping
  • 1 cup packed brown sugar
  • 2 large eggs, lightly beaten
  • 1 teaspoon vanilla extract
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon ground nutmeg
  • 1/2 teaspoon salt
  • 1 cup chopped pecans
  • 1/2 cup packed brown sugar (for topping)
  • 1/4 cup all-purpose flour

Instructions

  1. Place the sweet potato chunks into the basin of your slow cooker.
  2. Cook on low for 4 to 5 hours, or on high for 2 to 3 hours, until the potatoes are very tender.
  3. Drain off any excess liquid from the slow cooker.
  4. Add the milk, 1/2 cup melted butter, 1 cup brown sugar, eggs, vanilla, cinnamon, nutmeg, and salt to the potatoes.
  5. Mash the mixture directly in the slow cooker until it is creamy. You can use a potato masher or an electric hand mixer on low speed.
  6. In a separate small bowl, mix the 1/2 cup brown sugar, 1/4 cup flour, and the remaining 2 tablespoons of melted butter until crumbly. Stir in the chopped pecans. This is your crunchy topping.
  7. Spread the pecan mixture evenly over the sweet potato base in the slow cooker.
  8. Cover and cook on low for an additional 30 minutes, or until the topping is lightly toasted and the casserole is heated through.
  9. Serve directly from the slow cooker.

Notes

  • If you prefer a marshmallow topping, skip the pecan topping ingredients. Spread 2 cups of mini marshmallows over the base during the last 15 minutes of cooking until they are puffy and golden.
  • You can prepare the sweet potato base a day ahead. Store it covered in the refrigerator and add the topping just before the final 30-minute cook time.
  • For extra richness, substitute heavy cream for the milk.
