Method
Add meatballs
- Place the frozen fully cooked meatballs into the slow cooker in an even layer.
- Whisk hoisin sauce, soy sauce, honey, rice vinegar, garlic, sesame oil, ginger, and red pepper flakes until smooth.
- Pour the sauce mixture over the meatballs and stir gently to coat evenly.
Slow cook and thicken
- Cook on low for 3–4 hours until the meatballs are heated through and the sauce has thickened, or cook on high for 1.5–2 hours.
- Stir gently every hour during cooking to keep the coating even and glossy.
Serve
- Transfer the meatballs to a serving platter and garnish with sesame seeds and sliced green onions.
Notes
For the glossiest glaze, avoid over-stirring—stir gently every hour so the sauce clings instead of breaking. Store leftovers in the refrigerator up to 3 days. Freeze yes, freeze in a sealed container up to 2 months; thaw in the fridge and rewarm in the microwave or back in the slow cooker until hot. For a gluten-aware option, use tamari instead of soy sauce.
