Sweet Potato Crostini are bite-sized delights that combine the creamy, natural sweetness of mashed sweet potatoes with the satisfying crunch of toasted bread, creating a perfect balance of textures and flavors. The addition of pecans, brown sugar, and butter to the sweet potato mixture brings a depth of richness and nuttiness that will have your guests reaching for more.
Preheat your oven to 375°F. In a small bowl, mix sugar and cinnamon. Arrange bread slices on an ungreased baking sheet, brush each slice with butter, and sprinkle the sugar-cinnamon mixture over the top. Bake the bread slices for 5-7 minutes or until lightly browned. Remove the baking sheet from the oven and set the oven to broil.
In a separate bowl, combine mashed sweet potatoes, chopped pecans, brown sugar, and butter, mixing until well incorporated. Spread this sweet potato mixture generously over each toasted bread slice.
Top the sweet potato mixture on each crostini with marshmallows, gently pressing them into the mixture to ensure they stick. Place the baking sheet under the broiler, about 3-4 inches from the heat source. Broil the crostini for 1-2 minutes or until the marshmallows are lightly toasted and golden brown. Keep a close eye on them during this process to prevent burning. Once done, remove the sweet potato crostini from the oven and allow them to cool slightly before serving.
