Absolutely! Free-form your meatloaf into a loaf shape and place it on a foil-lined baking sheet. Scatter the sweet potato chunks around the outer edges of the meatloaf. Bake in a 350° preheated oven for 50 to 60 minutes until a thermometer inserted into the center reads 155°. Add the topping during the last two to three minutes of cooking and turn the oven to broil to caramelize it on the meatloaf. Remove from the oven and place the meatloaf on a cutting board to rest for ten minutes. Slice and serve.
