Make this creamy, comforting sweet potato casserole right in your slow cooker to save oven space during the holidays. This recipe offers a sweet, spiced base and includes instructions for both a crunchy pecan streusel and a classic marshmallow topping.

Ingredients

Scale
  • 3 pounds sweet potatoes, peeled and quartered
  • 1/2 cup milk
  • 1/2 cup granulated sugar
  • 1/2 cup packed light brown sugar
  • 2 large eggs, lightly beaten
  • 1/2 cup (1 stick) unsalted butter, melted, plus more for greasing
  • 1 teaspoon vanilla extract
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon ground nutmeg
  • 1/2 teaspoon salt
  • 1/2 cup milk (for topping)
  • 1 cup miniature marshmallows OR 1 cup pecan streusel topping ingredients (see notes)

Instructions

  1. Lightly grease the inside of a 4-quart or larger slow cooker insert with butter.
  2. Place the peeled and quartered sweet potatoes into the slow cooker. Add 1/2 cup of water.
  3. Cover and cook on LOW for 3 to 4 hours, or until the sweet potatoes are very tender when pierced with a fork.
  4. Carefully drain any excess liquid from the slow cooker.
  5. Add the 1/2 cup milk, granulated sugar, brown sugar, eggs, 1/2 cup melted butter, vanilla extract, cinnamon, nutmeg, and salt to the sweet potatoes in the slow cooker.
  6. Use a potato masher or an electric mixer on low speed to mash the mixture until it is smooth and creamy. Scrape down the sides as needed.
  7. Spread the sweet potato mixture evenly in the bottom of the slow cooker.
  8. Cook on LOW for 1 more hour, uncovered, to allow the mixture to set slightly.
  9. Prepare your desired topping. If using marshmallows, sprinkle them evenly over the top during the last 15 minutes of cooking. If using pecan streusel, sprinkle it evenly over the top during the last 30 minutes of cooking.
  10. Once the topping is melted or toasted, turn the slow cooker off. Serve warm directly from the crockpot.

Notes

  • For the Pecan Streusel Topping: Combine 1/2 cup all-purpose flour, 1/2 cup packed light brown sugar, 1/4 cup granulated sugar, 1/2 cup chopped pecans, and 1/4 cup cold, cubed butter in a small bowl. Use your fingers or a pastry blender to cut the butter into the dry ingredients until coarse crumbs form.
  • To keep the casserole warm for serving, switch the slow cooker to the ‘Keep Warm’ setting after the cooking time is complete.
  • This recipe is a wonderful oven space saver for your Thanksgiving side dish menu.
