Gather the ingredients and preheat the oven. Cook the bacon in the skillet. Remove and set on a paper towel to drain. Remove the skillet from the heat and reserve the excess bacon grease to a small bowl. Allow to cool slightly.
Refrigerated, this roasted brussels sprouts dish can stay in an air tight container for up to 4 days. Reheating is as easy as throwing the mixture back into the skillet, no extra oil required since there will be liquid from the apples that leach out naturally, and pop it into a 350F for 5-10 minutes.
