Easy Sweet Potatoes

3 large sweet potatoes
1/2tsp salt
4 T melted butter (1/2 stick)
1/4 c packed brown sugar
1-2 c mini marshmellows (however many you want!)

Boil sweet potatoes until tender. This can be done ahead of time; if you're making these with a big turkey dinner then boil the sweet potatoes right after you put the turkey in the oven. Once they're cooked and cooled, peel the skin off (it comes off easily). With a potato masher, mash the sweet potatoes in a large bowl and add salt, butter, and brown sugar. Mix with a hand mixer to make them nice and creamy. Spread evenly into an 8x8 casserole dish and top with mini marshmellows. Bake at 350 until heated through and marshmellows are browned. I keep this at the bottom of the oven to prevent the marshmellows from browning too soon.
