Costco mac and cheese is typically good for 3-5 days once opened and refrigerated properly.
If you leave it unopened, it can last for several months in the pantry, often until the expiration date on the package.
Store it in an airtight container after opening to keep it fresh.
Freezing is an option too; it can last for up to 6 months in the freezer.
When reheating, ensure it’s heated to at least 165°F to maintain quality and safety.
Always check for any signs of spoilage, like an off smell or discoloration, before consuming.
The shelf life can vary based on storage conditions and whether it has been opened or not.
Keep in mind that while it may still be safe to eat past these time frames, quality may diminish.
To enjoy it at its best, stick to the recommended storage times.
