  • 3 pounds sweet potatoes, peeled and cubed to 1"
  • 1/2 cup brown sugar
  • 1/2 cup half and half
  • 1/4 cup butter, melted
  • 1/4 cup 100% pure maple syrup
  • 1 teaspoon vanilla extract
  • 1 teaspoon kosher salt
  • 1/8 teaspoon cayenne pepper

Pecan Crumble Crust

  • 1 cup pecans, toasted and chopped
  • 2/3 cup brown sugar
  • 1/2 cup all purpose flour
  • 1/4 cup butter, melted
  • 1/4 teaspoon kosher salt


  • Line or spray a large slow cooker with non-stick spray.
  • Add the peeled and cubed sweet potatoes to the slow cooker.
  • Add the remaining ingredients and then stir to combine with the sweet potatoes. Pat them flat.

Pecan Crumble Crust

  • Toast the pecans on a large baking sheet at 350 degrees for 8 minutes until darker gold and fragrant. Roughly chop the pecans if using halves.
  • In a small mixing bowl, stir together the Pecan Crumble Crust ingredients and then sprinkle over the top of the sweet potato mixture in the slow cooker.
  • Cover the Crock Pot and cook on high for 4-5 hours or until the sweet potatoes are very tender in the center and the pecan crumble crust is golden.
  • Let the casserole rest for 15 - 30 minutes before serving so the caramel sauce around the sweet potatoes thickens to the perfect caramel consistency.


Make sure to let the casserole rest for 15-30 minutes after it has finished cooking to let the caramel sauce around the potatoes thicken.
The cayenne pepper in this dish does not make it spicy, is not noticeable, but serves to accent the other ingredients. It can be optional if desired.
