The key to these slow-cooker Thai-style chicken meatballs is to understand that the sauce gets better as it slowly cooks, but the meatballs don't. To fix that, we first cook the sticky sauce, packed with aromatics like lemongrass, ginger, and chilies, then add the flavorful meatballs right at the end just to cook them through. Crushed peanuts, scallion, and fresh lime juice finish it off for added texture, fresh flavor, and bright balance.
