Notes
This Recipe Can be Doubled: This is a great recipe for a crowd. Simply increase the ingredients proportionately. Freeze extras for a later date.
Finely Grate or Press Garlic: You want to avoid any big pieces of garlic so use a garlic press or zester to finely mince the garlic.
Don't Skip the Pepper: The crushed red pepper in this recipe gives just a hint of heat without being spicy. If you're not a fan of spice, simply cut back a little but don't omit it all together.
Use Your Air Fryer: You can also make these meatballs in the air fryer. Here's a great tutorial.
