How Long Does It Take to Thaw Shrimp? A Guide to Safely Defrosting Frozen Shrimp

Shrimp is one of the most versatile and delicious seafood ingredients that can be incorporated into a variety of dishes, from weeknight stir-frys to impressive appetizers for dinner parties Their sweet, briny flavor pairs well with pasta, salads, tacos, soups and more While fresh shrimp is great, frozen shrimp can be an even better option since it is flash-frozen at peak freshness and has a longer shelf life. Frozen shrimp can be stored in the freezer for up to a year before use. But when it comes time to cook, how long does it take to safely thaw frozen shrimp?

Properly thawing shrimp is important to avoid food safety issues and also to preserve texture and flavor. Here is a complete guide to thawing times for frozen shrimp and the best methods to use for perfect shrimp every time.

How Long Does Frozen Shrimp Last?

When stored continuously at 0°F, frozen shrimp will last in the freezer for 9-12 months before the quality starts to diminish Make sure to check the package for a “best by” date and optimal freezer storage time when purchasing frozen shrimp It’s best to use frozen shrimp by this date for premium quality and flavor.

Choose frozen shrimp that is vacuum sealed and free of ice crystals, which indicate freezer burn. Look for packages without tears or damage as well. Store frozen shrimp flat in the coldest part of the freezer, near the back where the temperature is most constant.

Thawing Timelines for Frozen Shrimp

The thawing time for frozen shrimp depends on a few factors:

• Size of the shrimp – Smaller shrimp thaw faster than large shrimp. U10-U15 count shrimp may take 1-2 hours less time to thaw than U8-U10.
• State of shrimp – Shell-on shrimp with heads take longer than peeled, deveined tail-on shrimp.
• Amount being thawed – A few shrimp thaw faster than a 1 lb bag.
• Thawing method – Cold water thaws faster than refrigerator thawing.

Here are general guidelines for approximately how long different amounts of peeled, deveined frozen shrimp take to thaw using different methods:

• 1 lb frozen shrimp, refrigerator: 12-24 hours
• 1 lb frozen shrimp, cold water: 1-2 hours
• 1/2 lb frozen shrimp, refrigerator: 6-12 hours
• 1/2 lb frozen shrimp, cold water: 30-60 minutes
• 1/4 lb or a few shrimp, refrigerator: 3-6 hours
• 1/4 lb or a few shrimp, cold water: 15-30 minutes

For shell-on frozen shrimp, add approximately 1-2 hours to thawing times. Jumbo shrimp may also take 1-2 hours longer than smaller shrimp.

Thawing Shrimp in the Refrigerator

Refrigerator thawing is the slowest method, but requires no monitoring or effort. It produces evenly thawed shrimp safe for consumption. Follow these tips:

• Place frozen shrimp in a bowl to catch drips and prevent cross-contamination.
• Allow 24 hours for 1 lb of shrimp to thaw fully. Smaller amounts may thaw faster.
• Rotate shrimp after 12 hours and break up any that are frozen together.
• Don’t refreeze thawed shrimp. Cook within 1-2 days.

Once thawed in the refrigerator, the shrimp are ready to use in recipes. Give them a rinse, pat dry and peel/devein if necessary. Refrigerator thawing results in minimal moisture loss so the shrimp retain their texture and flavor.

Quick Thawing Shrimp in Cold Water

For faster thawing, you can submerge a sealed bag of frozen shrimp in cold water. Use this method when short on time. Follow these steps:

• Place frozen shrimp in a zip-top plastic bag or leak-proof container.
• Submerge the bag in a bowl of cold tap water, allowing water to flow into the bag.
• Change the water every 30 minutes so it stays cold and thaws evenly.
• Small shrimp may thaw in 30-60 minutes, larger in 1-2 hours.

Shrimp thawed in cold water need to be cooked immediately, within 12 hours. They can become waterlogged and lose flavor if left to sit. Pat dry before cooking.

Can You Thaw Shrimp at Room Temperature?

It is not recommended to thaw shrimp at room temperature or warmer than 40°F. Bacteria grows rapidly in the “danger zone” between 40-140°F. Thawing on the counter risks exposing shrimp to these unsafe temperatures for too long.

Thawing in hot water is also unsafe as it may cook the outer layers while the inside remains frozen. Stick to cold water bath or refrigerator thawing only.

Cooking Frozen Shrimp

For ultimate convenience, you can skip thawing and cook frozen shrimp directly. They will take slightly longer to cook. Follow these tips:

Sautéing

• Use a hot pan and oil to sear the outside.
• Cook an extra 2-3 minutes, stirring frequently.
• Check internal temperature before serving.

Boiling

• Add extra time, up to 50% longer for large shrimp.
• Check a test shrimp at minimum cook time before removing from heat.

Baking/Broiling

• Increase cook time by 50% and check for doneness.
• May help to flip/rotate halfway through.

Grilling

• Defrost first unless shrimp are very small.
• If grilling frozen, use a hot grill and flip often.

Shrimp are fully cooked when opaque and reach 145°F internally. Cook just until pink and plump to avoid overcooking.

Tips for Thawing Shrimp

Follow these tips for safely thawed, delicious shrimp every time:

• Always thaw in the refrigerator or cold water method – never on the counter.
• Don’t thaw more than you plan to use within a day or two.
• Cook thawed shrimp within 1-2 days and don’t refreeze.
• Pat thawed shrimp dry before cooking to prevent splattering.
• Adjust seasonings or marinades to account for moisture released during thawing.
• Add a bit of extra time when cooking frozen shrimp, depending on the method.
• Check internal temperature and don’t overcook.

With the proper thawing method and timing, frozen shrimp can be an incredible ingredient to keep stocked in the freezer. Follow these guidelines for perfectly thawed shrimp ready to eat whenever a craving strikes or unexpected guests arrive.
