Ingredients
Scale
Sweet Potato Mixture
- 3 lbs fresh sweet potatoes (4-5 large), peeled and cut into 1-inch cubes
- 1/2 cup (120ml) milk
- 1 cup (225g) packed light brown sugar
- 1/4 cup (56g) unsalted butter, melted
- 2 eggs
- 1 tsp ground cinnamon
- 1/2 tsp ground nutmeg
- 1 tsp vanilla extract
- Pinch of salt
Streusel Topping
- 1/3 cup (44g) all purpose flour
- 1/3 cup (75g) light brown sugar, packed
- 1/2 tsp ground cinnamon
- 1/8 tsp ground nutmeg
- Pinch of ground cloves
- 3 tbsp (42g) salted butter, melted
Additional Topping
- 2-3 cups marshmallows
Instructions
- Preheat oven: Set your oven to 350°F (176°C) to prepare it for baking the casserole.
- Cook sweet potatoes: Place the peeled and cubed sweet potatoes in a large pot, cover them with water, and bring to a boil. Cook until the potatoes are fork-tender, approximately 8 minutes. Drain and transfer to a large bowl.
- Mash potatoes: Use a potato masher or fork to mash the sweet potatoes until smooth or your preferred consistency.
- Mix filling: Add the milk, 1 cup of light brown sugar, melted unsalted butter, eggs, cinnamon, nutmeg, vanilla extract, and a pinch of salt to the mashed sweet potatoes. Stir thoroughly until the mixture is well combined and smooth.
- Transfer to baking dish: Pour the sweet potato mixture into a 9×13-inch casserole dish. At this stage, you can cover and refrigerate the dish for up to 2 days if not baking immediately.
- Bake initially: Place the uncovered casserole in the preheated oven and bake for 25-30 minutes until heated through.
- Prepare streusel topping: In a bowl, combine the flour, 1/3 cup packed light brown sugar, cinnamon, nutmeg, and ground cloves. Add the melted salted butter and mix until the topping forms crumbly clusters.
- Finish baking: Remove the casserole from the oven. Sprinkle a layer of marshmallows over the top, followed by the streusel crumbs, and then add more marshmallows if you desire extra gooeyness. Return the casserole to the oven, baking an additional 10-15 minutes. For a golden-brown marshmallow top, broil at 400°F (204°C) briefly until marshmallows are toasted. Serve warm.
Notes
- To save time, sweet potatoes can be cooked in advance and refrigerated before assembling the casserole.
- Adjust marshmallow quantity according to taste for a sweeter topping.
- For a richer flavor, substitute milk with half-and-half or heavy cream.
- The casserole can be refrigerated after baking and reheated before serving.
- Broiling requires attention as marshmallows can burn quickly; watch carefully.
