Prepare the slow cooker by spraying with nonstick spray, then arrange the chicken drumsticks at the bottom.
In a small bowl, whisk together honey, soy sauce, ketchup, and minced garlic.
Pour the prepared sauce over the chicken in the slow cooker.
Cook on high for 4 hours or on low for 6 hours.
Once cooked, remove from the slow cooker and serve.
Optionally, garnish with sesame seeds, green onion, or parsley before serving. Enjoy!
