Can You Reheat Costco Chicken?

Can You Reheat Costco Chicken

Okay, yes. Obviously, you can reheat Costco chicken.

You can reheat anything. You’ll be hard pressed to find a food or beverage that has been refrigerated or frozen that you can’t reheat.

With Costco chicken, because you’re dealing with a whole bird, you’ll want to cut it up into sections. The best way to reheat anything that has already been cooked is to ensure you are reheating it in smaller segments. You don’t want them too small, of course, because then you run the risk of drying your little chicken bites out.

But if the chicken is too large, you have to worry about not cooking it all the way through.

Thus, cutting it into sections – half breasts, legs, and thighs – will allow you to reheat thoroughly and maintain moisture.

In general, foods that have been breaded or fried are best reheated in an oven or in an air fryer. Foods that have been baked or grilled are often best reheated back in the oven or back on the grill.

With Costco chicken, we are probably going to find the most success in the oven, but let’s run through all the appliances just to be sure.
