Ingredients
- 4 large sweet potatoes (about 3 pounds), peeled and cut into chunks
- 1/2 cup unsalted butter, melted
- 1/2 cup brown sugar, packed
- 1/3 cup whole milk
- 2 large eggs, beaten
- 1 teaspoon vanilla extract
- 1 teaspoon ground cinnamon
- 1/2 teaspoon ground nutmeg
- 1/2 teaspoon salt
- 2 cups mini marshmallows
- 1/2 cup chopped pecans (optional, for texture)
Instructions
- Boil the sweet potatoes: Place sweet potato chunks in a large pot and cover with water. Bring to a boil over high heat,then reduce to a simmer and cook until tender,about 15-20 minutes. Drain thoroughly.
- Mash and mix: In a large bowl,mash the potatoes until smooth but still slightly textured. Stir in melted butter, brown sugar, milk, eggs, vanilla, cinnamon, nutmeg, and salt until fully combined and creamy.
- Preheat the oven: Set to 350°F (175°C). Lightly grease a 9×13 inch casserole dish.
- Transfer mixture: Pour the sweet potato mixture into the prepared dish, smoothing the top with a spatula for even layering.
- Add the topping: Sprinkle chopped pecans evenly over the surface if using. Then heap mini marshmallows generously on top to form a thick,inviting layer.
- Bake: Place casserole in the oven and bake for 25-30 minutes. The marshmallows should puff up and turn a golden brown. Watch carefully to achieve that perfect gooey and lightly toasted crust.
- Cool briefly and serve: Let cool for 5 minutes to set before serving; this helps the casserole hold its shape and lets flavors meld beautifully.
Tips for Success: Crafting the Ultimate Gooey Marshmallow Topping
- Use mini marshmallows for more even melting and a smoother texture-large marshmallows tend to brown unevenly.
- Position the casserole rack in the upper third of the oven to achieve optimal browning of the marshmallows without burning.
- For an extra layer of flavor, lightly toast the pecans in a dry skillet until fragrant before sprinkling.
- If you want to avoid marshmallows sinking, gently press them into the sweet potato mixture just before baking.
- keep a close eye on the oven during the final 5 minutes to pull the casserole at the perfect golden gooey moment!
Selecting the Best Sweet Potatoes for maximum Flavor and Texture
Opt for firm, smooth-skinned sweet potatoes with vibrant orange flesh-it guarantees natural sweetness and creamy texture once cooked.Varieties like Beauregard or Garnet are excellent choices, boasting balanced moisture content and buttery consistency, which is essential for creating that luscious base that pairs so well with marshmallows.
Elevating Tradition with Unique twists and Serving suggestions
While the classic recipe shines on its own, consider stirring in a splash of maple syrup or a pinch of ground ginger for a warming depth. Swapping pecans for toasted walnuts or adding a dash of cayenne pepper can introduce surprising dimensions to this comfort food staple.
Present your timeless sweet potato casserole with a garnish of fresh rosemary sprigs or a dusting of powdered cinnamon for added visual appeal. Pair the dish alongside roasted turkey or pork tenderloin and a crisp winter salad to round out a festive feast.
