Crab cakes are a beloved seafood dish, known for their deliciously crispy exterior and tender, flavorful interior. Whether served as an appetizer, main dish, or part of a sandwich, they have an undeniable charm that makes them a go-to choice for seafood lovers. But what happens when you make a batch of crab cakes or buy some from your local market and you’re not sure if you can finish them all right away? Can they go bad? How long can you store them before they start to spoil?
Understanding how to properly store and recognize when crab cakes have gone bad is essential for ensuring both your safety and your enjoyment of the dish. In this guide, we’ll take a deep dive into the shelf life of crab cakes, how to store them properly, and the common signs of spoilage you should watch out for.
Yes, crab cakes can absolutely go bad. Like most prepared foods, they are susceptible to spoilage if not handled, stored, or consumed correctly. The primary culprit behind the degradation of crab cakes is bacteria. If they are exposed to temperatures that promote bacterial growth or if they’re stored too long, they can become a breeding ground for harmful microorganisms that pose health risks.
Since crab cakes typically contain seafood, dairy (like eggs or mayonnaise), and various seasonings, they need to be treated with particular care to prevent spoilage. The seafood can break down over time, losing both its texture and taste. Once crab cakes go bad, they won’t just taste off; they can also become a food safety hazard.

The shelf life of crab cakes varies based on several factors, such as whether they are homemade or store-bought, whether they are cooked or uncooked, and how they are stored. Here’s a breakdown of what to expect:
Typically last 3-4 days in the refrigerator if stored properly. If you want to keep them for a longer period, they can be frozen for up to 2-3 months without sacrificing too much quality.
Usually come with an expiration date on the packaging. If unopened, they can last for about 1-2 weeks beyond the expiration date, but it’s always best to check for any signs of spoilage. Once opened, they should be consumed within 3-4 days.
If you haven’t cooked your crab cakes yet, they should ideally be used within 1-2 days if refrigerated. If frozen, they can last 2-3 months before the quality begins to degrade.
These are generally safe to keep in the fridge for 2-3 days after purchase, but check the packaging for any specific guidance. If freezing, they can maintain their freshness for about 1-2 months.
There are several key signs that your crab cakes may have gone bad. If you notice any of the following, it’s best to err on the side of caution and dispose of them.

Proper storage is the key to maintaining the freshness and safety of crab cakes. Here’s what you should know about storing crab cakes correctly:
Crab cakes can typically last 3 to 4 days in the refrigerator when stored in an airtight container. After this period, they may start to lose their freshness and flavor.
Yes, crab cakes can go bad if left out at room temperature for more than 2 hours, as bacteria can rapidly grow in the temperature danger zone (40°F to 140°F). It is best to discard any crab cakes that have been left out for too long.
Signs that crab cakes have gone bad include a sour or off smell, a slimy texture, discoloration, or mold growth. If any of these signs are present, it is best to discard the crab cakes.
Yes, crab cakes can be frozen to extend their shelf life. When properly wrapped in plastic wrap or aluminum foil and stored in an airtight container or freezer bag, they can last for up to 3 months in the freezer.
Yes, cooked crab cakes generally spoil faster than uncooked ones. This is because cooking can alter the texture and make them more susceptible to bacterial growth. Uncooked crab cakes, when stored properly, can last a little longer in the refrigerator.
To keep crab cakes fresh, store them in an airtight container or wrap them tightly in plastic wrap or foil. Refrigerate them if you plan to eat them within a few days, or freeze them for longer storage.
It is not advisable to eat crab cakes that are past their expiration date, especially if they show any signs of spoilage, such as an off smell, discoloration, or slimy texture. Always prioritize food safety.
Yes, you can reheat frozen crab cakes. For the best results, thaw them in the refrigerator overnight before reheating them in the oven or on a skillet. This helps retain their texture and flavor.
To prevent crab cakes from drying out when reheating, cover them with foil or use a microwave-safe cover. You can also add a small amount of butter or broth to maintain moisture.
A slight fishy smell is common with crab cakes, especially if they are freshly cooked. However, if the smell is overly strong or sour, this is a sign that the crab cakes have gone bad and should be discarded.
