A Holiday Staple we Love

Marshmallows and sweet potatoes go hand-in-hand. Who agrees?

• Sweet and Savory. Although it’s not quite to dessert level, like our tasty Sweet Potato Pie.
• Perfect Holiday Side Dish. It’s especially popular at Thanksgiving, but we’ve made it for many holidays (like Easter and Christmas) and it’s always loved by all. It’s definitely a holiday staple!
• Can be Made Ahead of Time. For busy holidays and a crazy cooking schedule, it’s great to have a few dishes that can be made early, and this is one of them!

Ingredients

• Sweet Potatoes – This recipe calls for 4 cups cubed and peeled sweet potatoes and depending on the size of the potato, it’s about 4-6 of them.
  • NOTE: Sweet potatoes and true yams are different. They bot have orange flesh, but be sure to use sweet potatoes).
• Sugar – Adds the perfect amount of sweetness, but consider using other spices like nutmeg, cinnamon, and ginger for added flavor.
• Eggs
• Salt – Omit if using salted butter.
• Butter – We use unsalted butter but salted works too!
• Milk – We recommend using at least 2% milk, but use whole milk or heavy cream for a richer texture.
• Vanilla Extract
• Brown Sugar – This enhances the sweetness and makes it more flavorful.
• All-Purpose Flour
• Chopped Pecans – This is what we prefer but you can also use chopped walnuts.
• Mini Marshmallows – The perfect addition to this side, but you can also try covering the dish with dollops of meringue and baking until browned.

How to Make Sweet Potatoes with Marshmallows

1. PREP. Preheat your oven to 325°F and grease the 9×13-inch baking dish.
2. COOK & MASH. In a medium pot, cover the cubed sweet potatoes in water. Boil and cook over medium-high heat until tender. Once they are cooked, drain and mash with a potato masher.
3. MIX. In a large bowl, mix together the mashed sweet potatoes, sugar, eggs, salt, butter, milk, and vanilla extract, until smooth. Use a hand mixer or a stand mixer. Pour into a greased baking dish.
4. PECAN STREUSEL TOPPING. Mix the light brown sugar and flour in a medium bowl. Cut in the butter until the mixture is coarse. Stir in pecans, and sprinkle pecan topping over your sweet potato mixture.
5. BAKE. Bake in the oven for about 20 minutes. Then, take it out of the oven and sprinkle on the marshmallows and bake for an additional 10-15 minutes (or until lightly brown).

Note: You can always leave off the streusel and just do the marshmallows – still tasty!
