Sweet Potato Poutine

Sweet potato casserole gets a tricky makeover. What looks like a plate of poutine (french fries topped with gravy and cheese curds), is actually a familiar sweet trio: sweet potatoes, brown sugar and toasted marshmallows.

One 20-ounce bag frozen sweet potato fries

1/3 cup packed light brown sugar

4 tablespoons (1/2 stick) unsalted butter

1 tablespoon heavy cream

3/4 teaspoon pure vanilla extract

Kosher salt

2 tablespoons granulated sugar

1/2 teaspoon ground cinnamon

1/2 cup mini marshmallows


  1. Prepare the fries according to the package directions. Keep the oven on after they are done baking.
  2. Meanwhile, combine the brown sugar, butter, cream, vanilla and 1/2 teaspoon salt in a medium saucepan. Bring to a boil, stirring to dissolve the sugar. Once the sauce comes to a full and rolling boil, cook for 1 minute more. Remove from the heat and keep the sauce warm. 
  3. Whisk together the granulated sugar and cinnamon in a large bowl. Toss the hot baked fries in the cinnamon sugar until evenly coated. Pile them into an 8- to 9-inch heatproof serving dish and scatter the marshmallows over the top. Put the serving dish on a baking sheet and return to the oven. Bake until the marshmallows soften and just start to brown on top, about 5 minutes. Drizzle with the warm brown sugar sauce before serving.
