This Sweet Potato Casserole with Canned Yams is a quick and comforting side dish perfect for holiday meals or cozy family dinners. It combines creamy mashed yams sweetened with brown sugar and maple syrup, spiced with cinnamon, and topped with a buttery layer and golden mini marshmallows for a delightful finish.

Ingredients

Sweet Potato Mixture

  • 58 oz canned yams (2 cans of 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: Preheat your oven to 350°F (175°C) and grease a casserole dish using butter or non-stick spray to prevent sticking.
  2. Drain Yams: Open the canned yams and drain the liquid, reserving 2 tablespoons of the juice to adjust the casserole’s moisture if needed.
  3. Mash Yams: Transfer the yams into a large bowl and mash them thoroughly until mostly smooth.
  4. Mix Ingredients: Add brown sugar, maple syrup, and ground cinnamon to the mashed yams; continue mashing and mixing until the ingredients are well combined. If the mixture seems dry, incorporate a little of the reserved yam juice to reach a creamy consistency.
  5. Assemble in Dish: Spoon the sweet potato mixture evenly into the prepared baking dish and smooth the top. Dot the mixture with butter pieces on top for added richness.
  6. Bake the Casserole: Place the dish into the preheated oven and bake for 30 to 40 minutes until the casserole is heated through and slightly firm.
  7. Add Marshmallow Topping: Remove the casserole from the oven and sprinkle the mini marshmallows evenly over the top.
  8. Final Bake: Return to the oven and bake for an additional 5 to 10 minutes until the marshmallows are melted and golden brown. Optionally, broil for 1 to 2 minutes to achieve a crispier golden topping—watch carefully to avoid burning.

Notes

  • Use canned yams to save time without sacrificing flavor.
  • Reserve some yam juice to adjust moisture levels for the perfect creamy texture.
  • Broiling the marshmallow topping briefly can add a crispy caramelized finish.
  • For a richer flavor, use pure maple syrup instead of corn syrup.
  • This dish can be made ahead and reheated before serving.
