For the topping

  • ½ cup brown sugar
  • cup King Arthur all-purpose gluten-free flour
  • cup butter melted
  • 2 cups chopped raw pecans


  • Preheat oven to 350 degrees F.  
  • Combine all filling ingredients in a large bowl.

  • Mix topping ingredients until well combined and spread on top of the filling.  
  • Bake for 30-40 minutes until the filling starts bubbling and topping is lightly browned.


  • You can cook your sweet potatoes in advance. The quickest way to get them soft enough to mash is by steaming them on the stove or in an Instant Pot.
  • You could also peel the sweet potatoes, bake them in a 400-degree oven for about an hour, and then mash.
  • If you’re short on time, you can also use canned sweet potatoes or yams. Just make sure they are packed in water and that they are drained properly.
