Yes, these meatballs are perfect for freezing. Line them on a wide baking pan or tray with parchment paper. Arrange the meatballs 1 inch apart so they don't touch. Flash freeze for two hours. This ensures the meatballs don't stick together once transferred to a freezer bag. Remove from the baking sheet and transfer to a freezer bag for long-term storage. Store for up to 2 months.
