Sweet Potato Casserole Bottom

  • Get out and measure all of your ingredients.
  • In a large Dutch oven, over medium high heat, melt butter. Add the sweet potatoes, salt and pepper.
  • Add brown sugar and water.
  • Stir until blended.
  • Bring to a simmer. Reduce the heat to medium low, cover, and cook until sweet potatoes are fork tender, 45 to 60 minutes. Stir regularly.
  • When the sweet potatoes are tender, remove the lid and bring the sauce to a rapid simmer over medium-high heat. Continue to simmer until the sauce has reduced to a glaze, 7 to 10 minutes.
  • Adjust an oven rack to the middle position and heat the oven to 450 degrees. Pour the potato mixture into a 13 by 9-inch baking dish (or a shallow casserole dish of similar size).

Marshmallow Topping

  • Sprinkle marshmallows all over the top of your casserole.
  • Use as many marshmallows as you want to cover your sweet potato casserole.
  • Bake or broil until marshmallows are melted and brown.

Pecan Topping

  • Combine all of the ingredients in a medium sized bowl.
  • Sprinkle topping over top of the potatoes. Bake until the pecans are toasted and crisp, 10 to 15 minutes.
  • Serve immediately.
  • Enjoy every bite!
