How to choose crab legs

When choosing crab legs, look for those that are bright in color and have a firm, intact shell. Fresh crab legs should have a clean, briny scent reminiscent of the ocean, indicating they were caught recently.

Avoid crab legs that have a strong, fishy odor or show signs of discoloration, as these can be indicators of spoilage. Crab legs that feel heavy for their size and have a slight bounce when pressed are likely to be fresh and meaty, ensuring a satisfying dining experience.

How to store crab legs

To ensure your crab legs remain fresh and flavorful, store them in the refrigerator as soon as possible after purchase. Keep them in their original packaging or place them in an airtight container to prevent exposure to air, which can lead to spoilage. Ideally, the temperature should be maintained between 32-34°F (0-1°C) to keep the crab legs at their best quality.

Avoid storing crab legs in the freezer for extended periods, as this can affect their texture and taste. It's crucial to consume them within 1-2 days of purchase for optimal freshness. If you must freeze them, wrap them tightly in plastic wrap and then in aluminum foil to minimize freezer burn, and consume them within three months for the best flavor.

✅ Extra Tip

To enhance the flavor of crab legs, steam them with a splash of white wine and a sprinkle of Old Bay seasoning for a deliciously aromatic experience.

How long does it last?

Crab legs are best enjoyed fresh, but their shelf life can vary depending on how they are stored. When kept in the refrigerator, cooked crab legs can last for about 3-5 days, while raw crab legs should ideally be cooked within 1-2 days for optimal freshness. If you want to extend their longevity, freezing is an excellent option; properly frozen crab legs can last for up to 6 months without significant loss of quality. To ensure the best taste and texture, it's important to store them in an airtight container or tightly wrapped in plastic wrap before freezing. Always remember to thaw them in the refrigerator before cooking to maintain their flavor and quality.

What to do with leftovers?

Leftover crab legs can be a delightful treat if you know how to repurpose them. Start by removing the meat and storing it in an airtight container in the refrigerator for up to three days. Use the crab meat in a rich seafood chowder or toss it into a fresh pasta dish for a touch of elegance. You can also mix it with mayonnaise, lemon juice, and herbs to create a delicious crab salad or use it as a filling for crab cakes. If you're feeling adventurous, consider making a crab dip for your next gathering, pairing it with crackers or fresh vegetables. For longer storage, crab meat can be frozen, allowing you to enjoy the flavors of the ocean even after the feast is over.
