Costco croissants typically last about 1 to 2 days at room temperature if they are left unopened, and about a week once opened.
If you want to extend their freshness, it’s best to store them in the refrigerator, where they can last for up to a week.
Freezing is another excellent option, allowing Costco croissants to maintain their quality for about 1 to 2 months. Just make sure to wrap them tightly to prevent freezer burn.
When thawing frozen croissants, let them sit at room temperature for a couple of hours or heat them in the oven for a few minutes. This helps regain their flaky and delicious texture.
Be cautious, as croissants can go stale quickly due to their buttery composition. If they start to feel hard or dry, it’s time to toss them out.
Storing them properly from the start will keep those warm, buttery flavors intact for longer.
