Equipment

  • Pie dish 8 ½ in/ 21 cm or a similar-sized baking dish

Ingredients

  • 1.2 lb sweet potatoes 550 g, Note 2
  • ⅓ cup brown sugar 60 g/2 oz, Note 3
  • 1 ½ tablespoons unsalted butter Note 4
  • ¼ teaspoon fine sea salt or Kosher
  • ⅓ cup pecans chopped, 30 g/ 1 oz
  • 1 cup mini marshmallows or as needed to cover the casserole

Instructions

  • Preheat the oven to 400°F (200°C) and butter the baking dish.
  • Cook sweet potatoes: Peel and cube them. Bring a pot of water to a boil, carefully add the sweet potato cubes, and cook them for about 12-15 minutes or until tender. Drain well in a colander.

Notes

  1. The recipe can be easily doubled. Bake the sweet potato casserole in a 9x13 inches (23x33 cm) baking dish.
  2. I had one large sweet potato.
  3. For a lower-calorie version, use xylitol and add 1 tablespoon of molasses. Xylitol has 40% fewer calories than sugar, and the molasses imparts the sweetener a brown sugar-like texture and flavor.
  4. If using salted butter, omit the salt in the recipe.
  5. Spices: You can add a pinch of cinnamon and about ¼ teaspoon of vanilla extract if you like.
