Peel the sweet potatoes and slice. Slices should be about 1/2 inch thick.

Step 2

In a mixing bowl, stir together the white sugar, brown sugar, cinnamon, nutmeg, and salt.

Melt the butter in a large skillet or Dutch oven at Medium heat. Stir the sugar mixture into the butter until melted into a sauce. Stir in the sliced potatoes, coating fully with the sauce.

Cover the skillet and reduce the heat to Low. Cook for 40 minutes to 1 hour, or until potatoes are tender and candied. Don't stir.

Step 5

Remove from the stovetop and gently stir in the vanilla.
