Preheat your oven to 375ºF (190ºC).
In a small bowl, stir together melted butter, brown sugar, vanilla extract, ground cinnamon, ground ginger, and kosher salt well.
8 tablespoon butter, 1 cup brown sugar, 1 tablespoon vanilla extract, 2 teaspoon ground cinnamon, 1 teaspoon ground ginger, ½ teaspoon kosher salt
Use your clean hands or a large spoon to mix the butter-sugar mixture and sweet potatoes in a baking dish or casserole dish. Make sure each sweet potato chunk is well coated in the mixture and the potatoes are laying in an even layer. It's okay if it's not in one layer.
6 medium sized sweet potatoes
Bake the candied yams in the preheated oven for 55 minutes, until potatoes are fork-tender, the sugar and potatoes have caramelized, and there is that buttery syrup in the baking dish.
Let cool for at least 5 minutes before serving, sugar burns aren't fun!
