Instructions
- Cook the Sweet Potatoes: Place the peeled and cubed sweet potatoes in a large pot filled with cold water. Bring to a boil, then reduce heat and simmer until tender-about 15 to 20 minutes. Test by piercing with a fork; it should slide easily without falling apart.
- Mash and combine: Drain the potatoes well and return them to the pot. Add the melted butter, maple syrup, milk, cinnamon, nutmeg, ginger, sea salt, and vanilla extract if using. mash thoroughly until smooth and creamy, ensuring a luscious, even texture.
- Prepare the Casserole Dish: Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with butter or nonstick spray.
- assemble the Base: Spread the sweet potato mash evenly into the prepared dish. Smooth the surface with a spatula for a consistent layer.
- Add Nutty Crunch: Sprinkle the chopped pecans or walnuts over the sweet potato layer, evenly distributing for every bite to sing with texture.
- Top with Marshmallows: Generously cover the entire surface with mini marshmallows. They should form a thick, cloud-like blanket.
- Bake to Golden Perfection: Place the casserole in the oven and bake for 25 minutes, or until the marshmallows puff and turn golden brown. Keep a close eye in the last 5 minutes to avoid burning-marshmallows toast fast!
- Final Broil for Crisp Crust: For an irresistible toasted finish, switch the oven to broil for 1-2 minutes.Watch carefully and remove once the marshmallows have a deep caramel color with tiny crisp edges.
- Rest and Serve: Allow the casserole to rest for 5 minutes before serving, letting the layers set beautifully.
Tips for Success
- Choosing sweet Potatoes: Select firm, smooth-skinned orange-fleshed sweet potatoes for the best balance of natural sweetness and creamy texture. Avoid overly large tubers to reduce fibrous bite.
- Spices Matter: Use freshly ground cinnamon, nutmeg, and ginger to elevate the flavor profile-pre-ground alternatives can quickly lose vibrance.
- Nut Substitutions: Feel free to swap pecans for toasted walnuts or almonds based on preference or availability. For a nut-free version, sprinkle extra marshmallows or crushed graham crackers for crunch.
- Make-Ahead Magic: Prepare the sweet potato layer up to 24 hours in advance, refrigerate uncovered, then add nuts and marshmallows right before baking.
- Marshmallow Watch: Broiling is the secret to that glossy, golden mantle but requires attention. Step away briefly, and you might toast into charcoal.
