Ingredients

Scale

Sweet Potato Mixture

  • 58 oz canned yams (2 cans, 29 oz each)
  • ¼ cup brown sugar
  • 1 tbsp pure maple syrup
  • 1 tsp ground cinnamon
  • 3 tbsp butter

Topping

  • 2 cups mini marshmallows

Instructions

  1. Preheat and prepare dish: Preheat your oven to 350℉ (175℃). Grease a casserole dish with butter or non-stick spray to prevent sticking.
  2. Drain and reserve juice: Drain the canned yams thoroughly, reserving 2 tablespoons of the liquid in case the casserole seems dry during mixing.
  3. Mash yams: Transfer the yams into a large mixing bowl and mash them until smooth or your desired consistency.
  4. Add flavorings and blend: Mix in the brown sugar, pure maple syrup, and ground cinnamon. Continue mashing until all ingredients are thoroughly blended. If the mixture feels too dry, add some of the reserved juice gradually to soften.
  5. Arrange in baking dish: Spoon the sweet potato mixture evenly into the prepared casserole dish, smoothing the top with a spatula. Dot the surface with the 3 tablespoons of butter.
  6. Bake the casserole: Place the casserole in the preheated oven and bake for 30 to 40 minutes until the sweet potato mixture is heated through and starting to bubble.
  7. Add marshmallow topping: Remove the casserole from the oven and evenly sprinkle the 2 cups of mini marshmallows over the top. Return it to the oven and bake for an additional 5 to 10 minutes until the marshmallows are golden brown and melted.
  8. Optional broil: For an extra golden and toasted marshmallow topping, you may broil the casserole for 1 to 2 minutes watching closely to prevent burning.

Notes

  • Using canned yams saves time and effort but make sure to drain thoroughly.
  • If you prefer a less sweet casserole, reduce the amount of brown sugar or maple syrup.
  • For a richer flavor, use real butter rather than margarine or spray.
  • Broiling is optional and should be watched carefully as marshmallows can burn quickly.
  • This casserole can be prepared a day ahead and reheated before serving.
