How to Make It
Peel and Prepare the Sweet Potatoes
Start by peeling those sweet potatoes and cutting them into large chunks. Place them in a large saucepan and cover them with water. You want to make sure they’re submerged so they can cook evenly.
Boil Until Tender
Bring the water to a boil and let those sweet potatoes bubble away until they are tender—about 15-20 minutes. Just fork-test a few—if they pierce easily, they’re ready to go!
Mash Them Up
Drain the sweet potatoes and return them to the saucepan. Grab your trusty potato masher and mash them up until they’re ultra-smooth and creamy. Trust me, the more you mash, the better the texture!
Mix in the Goodies
Now it’s time to mix in that melted butter, brown sugar, salt, cinnamon, vanilla extract, and nutmeg. Stir it all together until everything is beautifully combined. Just the smell of this mixture will make your heart sing!
Prepare the Baking Dish
Grab a 9×13 inch baking dish and give it a generous spray of cooking oil. We want to make sure nothing sticks to our cozy creation!
Spread the Filling
Spread the sweet potato filling evenly in the prepared baking dish. Don’t be shy; use a spatula to get it nice and smooth.
Top with Marshmallows
Now for the fun part! Top it off with mini marshmallows, spreading them out in an even layer. Imagine how that bubbly, gooey topping will look when it’s done!
Bake to Perfection
Pop that casserole in a preheated oven at 350°F (175°C) for 25-35 minutes. Keep an eye on it toward the end to get that perfect golden brown marshmallow topping — we’re looking for gooey goodness here!
Pro Tips for Success
- Choose Sweet Potatoes Wisely: Look for firm, smooth sweet potatoes free of blemishes.
- Don’t Overmix: Overmixing the filling can lead to a gummy texture. Just blend until combined!
- Keep an Eye on the Marshmallows: They can go from golden to burnt in a blink—stay vigilant!
- Add More Spice: Feel free to increase the cinnamon or add a pinch of ginger for a zing!
Flavor Variations
- Nutty Crunch: Sprinkle chopped pecans or walnuts on top before baking for some delightful texture.
- Seasonal Twist: Add dried cranberries or diced apples to the filling for a fruity surprise!
- Soothing Ginger: A tsp of fresh ginger or a sprinkle of ginger powder can give an exciting warm flavor note!
Serving Suggestions
This casserole is perfect alongside roasted turkey or honey-glazed ham for holiday feasts. For a beautiful presentation, serve it in a rustic baking dish or transfer to a colorful serving bowl. Pair it with a crisp apple cider or a spiced chai latte for a delightful twist!
Make-Ahead & Storage
You can prepare the sweet potato filling up to two days in advance—just store it in the fridge before assembling with marshmallows. Leftovers can be stored in an airtight container in the fridge for up to 4 days.
Leftovers
Got leftovers? Reheat that casserole for breakfast! Slice it up and warm it in a skillet for a crispy exterior. Add a dollop of Greek yogurt or whipped cream on top for an indulgent treat.
Freezing
Yes, this casserole can be frozen! Just make sure to freeze it before baking. Wrap tightly in plastic wrap and aluminum foil. When you’re ready to enjoy, thaw it in the fridge overnight before baking.
