Making these countless times, I've learned that the ratio of sauce to meatballs is crucial. Too much sauce makes them soupy, too little and they won't glaze properly. This recipe hits the sweet spot perfectly.
Mastering the Sauce
The key is letting the sauce simmer and reduce slightly, which concentrates the flavors and creates that perfect sticky coating. I've found that the last hour of cooking is when the magic really happens.
Temperature Management
Starting with frozen meatballs actually helps the sauce adhere better as it slowly heats. Room temperature meatballs tend to break apart more easily during cooking.
The Art of Serving
For parties, I like to transfer them to a serving dish with a slotted spoon, leaving excess sauce behind. This makes them easier to pick up with toothpicks while staying perfectly glazed.

These Sweet & Spicy Slow Cooker Meatballs have become my signature party dish - they're that perfect combination of effortless preparation and crowd-pleasing results that every host dreams of.
