How to bake meatballs in the oven for the best results?

To bake meatballs in the oven for the best results, preheat the oven to 400F, place the meatballs on a baking sheet lined with parchment paper, and bake for 20-25 minutes or until they are cooked through and browned on the outside. Make sure to flip the meatballs halfway through cooking for even browning.
