Description

A festive Sweet Potato Casserole topped with marshmallows – a holiday favorite side dish with creamy, buttery sweet potatoes and a touch of sweetness from brown sugar.

Ingredients
  • 5 Cups Sweet Potatoes Cubed (approximately 2 medium sweet potatoes peeled and cut into cubes)
  • 2 Tablespoon Light Brown Sugar
  • 3 Tablespoons Butter (one to grease the dish, two to put on top of the sweet potatoes)
  • 2 Cups Small Marshmallows
Instructions
  1. Gather the Ingredients:Ingredients for sweet potato casserole: brown sugar, a large sweet potato, butter, and marshmallows.

    Gather together all your ingredients, brown sugar, sweet potato, butter, and marshmallows. You’ll need 5 cups of peeled and chopped sweet potatoes, 2 tablespoons of brown sugar, 3 tablespoons of butter, and 2 cups of mini marshmallows.

  2. Prepare the Baking Dish:Baking dish greased with butter, ready for the sweet potato casserole.

    Grease the baking dish with a tablespoon of butter. This will help prevent the sweet potatoes from sticking and add a subtle buttery flavor.

  3. Combine the Ingredients:Chopped sweet potatoes in the baking dish with butter and brown sugar sprinkled on top.

    Place the peeled and chopped sweet potatoes into the greased baking dish. Sprinkle the brown sugar over the sweet potatoes, and dot with butter pieces. This will create a deliciously sweet and buttery coating as it bakes.

  4. Bake Initial Stage:Sweet potato casserole with butter and brown sugar placed in the oven.

    Preheat the oven to 375°F (190°C). Place the baking dish in the oven and bake for 30 minutes, or until the sweet potatoes are tender. Stir halfway through if needed to ensure even cooking.

  5. Add Marshmallow Topping:Sweet potato casserole topped with marshmallows, ready for final baking.

    Once the sweet potatoes are tender, remove the dish from the oven and sprinkle mini marshmallows evenly over the top. The marshmallows will toast to a golden brown, adding a sweet, gooey layer.

  6. Final Bake:

    Return the casserole to the oven and bake for an additional 5 minutes, or until the marshmallows are golden and bubbly.

  7. Rest and Serve:Finished sweet potato casserole with golden-brown marshmallows, garnished with flowers for presentation.

    Let the casserole rest for 5 minutes before serving to allow the flavors to meld and the marshmallows to set slightly.

Note

Tips for Success

  • Cut Sweet Potatoes Evenly: To ensure even cooking, chop the sweet potatoes into similar-sized pieces.
  • Use Fresh Marshmallows: Fresh marshmallows melt more uniformly and provide the best texture.
  • Adjust Sweetness: If you prefer a less sweet casserole, you can reduce the brown sugar slightly.
  • Make Ahead: This casserole can be prepared up to the marshmallow step a day in advance. Store in the refrigerator and add marshmallows just before the final bake.

Enjoy your festive Sweet Potato Casserole, a perfect balance of sweetness, creaminess, and holiday warmth!
