Mashed Sweet Potatoes with Brown Sugar Walnut Crust

As if the name isn’t a seller, this mashed sweet potato with brown sugar walnut crust has a mix of sweet and spicy. I add a little cayenne pepper to the sweet potatoes once they’re mashed and it gives a nice bite at the end. The key to the crunch is to roast the walnuts for a few minutes before crushing them and mixing them with the brown sugar mixture. Have I sold you on this dish yet?

This is a perfect Thanksgiving side dish, but you’ll notice I have it serving a smaller group below in the ingredients, but if you need more, just double the recipe.

recipes with rachel sweet potato with brown sugar walnut crust


  • 4 potatoes, peeled and cubed
  • 1 tsp salt
  • 2 tbs butter
  • 2 tbs maple syrup
  • 1/4 cup milk
  • 1 tsp vanilla extract
  • 1 pinch all spice
  • 1 pinch cayenne pepper

For the crust:

  • 1 cup chopped walnuts
  • 1/2 cup brown sugar
  • 1/4 cup flour
  • 1/4 cup cup butter


  • In a large pot of boiling water, add the sweet potato cubes. Boil until they’re soft and ready to be mashed.
  • While those are boiling, preheat the oven to 400 degrees.
  • Set the walnuts on a baking sheet and roast in the oven for 5 minutes.
  • Once the 5 minutes are up, remove them from the oven and using a meat mallet or something hard, crush the walnuts into smaller pieces for a crush. Not too small though! You want to have a nice crunch with the sweet potatoes. Set the walnuts aside.
  • Back to the potatoes, drain all of the water and then put the potatoes back into the hot pot. Add in the 2 tbs of butter and using a mashing tool, mash the potatoes until all of the lumps are gone.
  • Add in the maple syrup, milk, vanilla extract, all spice and cayenne pepper. Stir until it’s all mixed up.
  • Spoon the sweet potatoes into your serving dish and then set aside.
  • For the crust: In a small bowl, melt the 1/4 cup butter.
  • Add in the flour and brown sugar into the melted butter and stir until it’s a smooth consistency.
  • Add in the walnuts and stir until all of the walnuts are coated.
  • Sprinkle the walnuts over the sweet potato dish.
  • Serve warm!
