Let’s talk ribs

I do exactly the same as you except I usually get them from BJs. I have not been happy with smoked and frozen ribs (I usually do loin backs). Something, admittedly subtle, happens to the texture and flavor that reheating can't restore to the goodness of just out of the smoker. I think it has something to do with the residual aromatic smoke flavor and slight bark on the surface that just don't survive the freezing and thawing process. Also, I freeze the uncooked ribs without any trimming or membrane removal. Just my $.02.

I usually buy a three pack from Sams, cook whatever I need and freeze the other rack(s). I prefer to freeze/thaw/cook rather than cook/freeze/reheat.

What brand of ribs does your Costco carry? Swift or Smithfield? Smithfield sells enhanced as well as non enhanced ribs.

I don't remember but I'll have a look the next time we are over there.

I agree with AndyJ. I buy them on sale, cook what I want, and freeze the rest still in the shrink wrap un-trimmed and membrane on. There's nothing like the taste of ribs right out of the smoker. You lose that when you cook, freeze, then re-heat. They're just not as good.

Well I finally got over to CostCo yesterday.
They were selling Swift products.
