Prepare a baking sheet by lining with aluminum foil or parchment paper.
Add all ingredients for the meatball mixture to a large mixing bowl.
Gently combine the ingredients with clean hands or with a large spoon. If time allows, cover the bowl, and let the mixture rest in the refrigerator for a few hours or overnight to let the flavors marry (completely optional).
Using a medium spoon or tablespoon, roll equal portions of the mixture and place onto the baking sheet. The meatballs should be about the size of a golf ball.
Roll with very slightly wet hands or using cooking spray on your hands to aid in rolling as the mixture will be quite sticky.
Transfer rolled meatballs to a clean baking sheet and bake in in the lower third of your preheated oven for about 15 to 20 minutes. I like to bake them on the lowest rack for best browning. You may turn the meatballs halfway through cooking (at about 7 to 10 minutes).
Top with your favorite red sauce (optional)
Notes
Store any leftover meatballs in an airtight container or Ziplock bag in the refrigerator for up to five days.
Freeze leftover fully cooked meatballs in a freezer-safe container or Ziplock bag for up to six months. Like with any meat, beware of freezer burn!
Reheat refrigerated meatballs in the oven at 350 degrees for 10-15 minutes.
Reheat frozen meatballs by letting them thaw in the fridge overnight and then warming in the oven as explained above.
