Crank it up to 375°F. That’s your sweet spot for how to cook Costco chicken meatballs. Give the oven a moment to reach that cosy warmth before you start.

Arranging meatballs on a baking sheet

Space them out. They’re social but not that social. Jazz them up with some Italian seasoning if you’re feeling fancy.

Twenty minutes should do the trick. But hey, trust in the power of the meat thermometer – 165°F means you’re golden.


Sizzle and spice and everything nice

Choosing the right skillet or pan

Heavy-bottomed pans are your best buds. They give you that even heat distribution for a superior sear.
