The soft and tender texture of mashed sweet potatoes with marshmallows make you feel in 7th heaven with this ultimate holiday side dish. No thanksgiving dinner or roast is completely without this unassuming casserole. Sweet potatoes are super versatile, yet, we always underestimate them.
And the marshmallows? Yes, they make all the difference. They add just the right amount of sweetness and nicely compliment the savory sweet potatoes. Isn’t it anyhow funny, how we call them sweet potatoes, yet they are not. So the marshmallows put the sweet back into it.
While you obviously can’t go wrong with the standard white marshmallow, I recommend using mini versions and opting for some colorful ones while you’re at it. I fell in love with golden mini marshmellows as they make everything instantly a little more festive and cheerful. This is especially true, if you prepare them for Thanksgiving or around christmas time. The shinnier, the merrier. Marshmallows all the way…
The recipefor my mashed sweet potatoes with marshmallows uses brown sugar as it gives the dish a nice caramlizing flavor. So the reason for sugar is not to simply make it sweeter, but to enhance the overall richness of the mash and that includes the savory components. You will achieve this with brown sugar, but not with white sugar.
