Preheat oven to 400°F and line a rimmed baking sheet with parchment paper.
In a large mixing bowl, gently mix together the meatball ingredients until just combined.
Roll small 1.5 inch meatballs and place them onto the prepared baking sheet.
Bake meatballs for 15-18 minutes, flipping halfway through, until browned. (You may need to add more time for larger meatballs.) Don’t worry if it’s not fully cooked through, it will continue to cook in the crockpot. Transfer the browned meatballs into the crockpot.
In a bowl, combine the cranberry sauce ingredients and whisk together. Pour over the meatballs.
Cover and cook for 4-6 hours on low or 2-3 hours on high, until the meatballs reach a minimal internal temperature of 145°F.
