What You Need:
- Sweet Potatoes
- Side Note: I successfully grew sweet potatoes this year and am obsessed with using them in recipes this Fall, so expect to see them highlighted in upcoming recipes. My favorite is my No-bean Sweet Potato Chili, you should check it out.
- Unsalted Butter (so easy to make butter yourself in 20 minutes if you have a stand mixer and a whisk attachment))
- Heavy Cream (for rich creaminess, or milk for a lighter option)
- Maple Syrup -the real kind(or brown sugar or you can leave this out if looking for a lighter version)
- Cinnamon and Vanilla Extract (elevantes the flavors and adds warmth to the dish)
- Salt (because what dish doesn’t need a little)
- Marshmallows and Butter (for marshmallow ribbon)
Recipe Substitutions And Notes
- Don’t skip the cinnamon and vanilla extract—it really elevates the flavor and adds a warm, cozy touch.
- Adjust the sweetness by tasting as you go. You can add a little more brown sugar if you want that extra sweetness, or keep it light for a savory twist.
How to Make Cinnamon Mashed Sweet Potatoes with Marshmallow Ribbon:
- Cut your sweet potatoes into 1 to 1.5-inch cubes—this size cooks to fork-tender perfection in about 12 minutes on a simmer. Add the cubes to a large pot, cover them with water, and stir in a teaspoon of salt. Bring the water to a boil, then cover and reduce the heat to medium-high. Let the sweet potatoes cook for 12-15 minutes, or until you can easily pierce them with a fork. Once they’re done, drain the water and return the sweet potatoes to the pot.
- This part sounds strange but is important if you don’t want watery potatoes. Turn the heat on under the pot to medium-high and let the sweet potatoes sit for about 30 seconds, to evaporate any excess water. This little step makes your mashed sweet potatoes creamier.
- Now, grab your potato masher (or electric mixer, if you’re in the mood for smooth mashed potatoes) and mash the sweet potatoes to your desired texture. Add the unsalted butter, heavy cream (or milk), maple syrup, cinnamon, vanilla extract, and salt. Stir everything together until it’s creamy and smooth. Taste, and if you feel like it needs more sweetness or cinnamon, go ahead and adjust it!
- In a small saucepan, melt a little butter over medium heat. Add your mini marshmallows (or regular marshmallows if you have them on hand) and stir them constantly until they melt and form a smooth mixture. This is your marshmallow ribbon!
- Transfer your cinnamon mashed sweet potatoes into a serving dish. Drizzle that marshmallow mixture over the top, then gently swirl it through the potatoes to create a beautiful ribbon effect. Feel free to leave some marshmallow on top for a nice candy-like topping and a sprinkle of cinnamon makes the dish pop.
- Serve this warm alongside your favorite Thanksgiving sides or any hearty meal. It’s the perfect balance of sweet and savory, and the marshmallow ribbons take it to the next level!
