Notes

Tips for making this recipe:

  • As I pointed out in my recipe for Baked Meatballs, soaking the breadcrumbs and milk before adding the other ingredients is the key to making the best meatballs that stay moist.
  • To store: Add the meatballs, relish, and mayo mixture in separate covered containers and eat within 3 days. Reheat the meatballs in the oven or air fryer at 400 degrees for 5-8 minutes and assemble the rest of the ingredients.
