How Long to Cook Crabs for Perfectly Tender Meat Every Time

As a seafood lover, few things beat a tender, flaky, freshly-cooked crab. The sweet, succulent meat is reason enough to cook up this crustacean delicacy. But achieving that ideal texture requires cooking your crab for just the right amount of time. Undercook it, and the meat remains gummy and unappetizing. Cook it too long, and it becomes unpleasantly rubbery. So how long should you cook crabs to end up with tender, not tough, results?

The cooking time depends largely on the size and type of crab being prepared Smaller crabs cook faster, while larger crabs require more time. The method used, such as boiling, steaming, baking or grilling, also impacts total cook time. Read on for a complete guide to determining the perfect crab cooking time for flawlessly tender meat.

Factors That Influence Crab Cooking Times

Several key factors affect how long it takes to cook crab

Crab size – Large king or snow crab legs take longer to cook than smaller blue crabs or Dungeness
Cooking method – Boiling, steaming, baking and grilling require different cook times.
Preparation – Whole crabs take longer than cut-up pieces or crab cakes.
Quantity – Cooking more crabs at once slightly increases cook time.
Altitude – At higher altitudes, the boiling point of water is lower, increasing cook times.

How to Tell When Crab is Fully Cooked

While recommended cooking times provide useful guidelines, the best way to test doneness is by appearance and texture:

Shells turn bright red/orange when fully cooked
Meat changes from translucent to opaque white
Flesh feels firm yet flakes easily when poked with a fork
Juices run clear, not milky

Check the thickest part of the body and legs for doneness cues. It’s better to slightly undercook and allow carryover cooking to finish rather than overcooking.

Boiling Times for Different Types of Crab

Soft shell crabs – 3 to 5 minutes

Small blue crabs – 8 to 12 minutes

Large Dungeness crabs – 12 to 18 minutes

King crab legs – 6 to 8 minutes

Snow crab legs – 4 to 5 minutes

Stone crab claws – 7 to 9 minutes

Check for doneness starting at the lowest recommended time. Adjust the boiling time up slightly as needed to achieve tender meat.

Steaming Times for Common Crab Varieties

Soft shell crabs – 4 to 6 minutes

Small blue crabs – 10 to 15 minutes

Dungeness crabs – 10 to 20 minutes

Alaskan king crab – 8 to 12 minutes

Snow crab legs – 5 to 7 minutes

Stone crab claws – 8 to 12 minutes

As with boiling, start checking for done cues at the shortest listed steaming time for each type of crab.

Oven Baking Times for Whole Crabs and Pieces

Whole Dungeness or blue crabs – 15 to 20 minutes at 400°F

Crab cakes – 10 to 12 minutes at 400°F

Crab stuffed mushrooms – 12 to 15 minutes at 375°F

Crab legs – 5 to 7 minutes at 375°F

Always allow a couple minutes extra baking time for very large whole crabs. Check for doneness 5 minutes early.

Grilling Times for Crabs and Crab Legs

Whole crabs – 8 to 12 minutes total, flipping halfway

Crab cakes – 3 to 5 minutes per side

Crab legs – 4 to 6 minutes per side

Soft shell crabs – 2 to 3 minutes per side

Brush crabs with oil or butter before grilling. Cook times vary based on heat intensity.

Tips for Boiling Crabs Perfectly Every Time

Follow these best practices for perfectly cooked crab when boiling:

Use plenty of water to allow crabs space to boil rapidly.
Add lemon, seafood seasoning or Old Bay to the water for flavor.
Gently lower crabs into boiling water using a large strainer or tongs.
Time the boil starting immediately once water returns to a boil.
Check for doneness early and cook longer if needed.
Shock in ice bath to stop cooking once boiled.

Serving Suggestions for Cooked Crabs

Tender, flaky crab meat deserves to be showcased in delicious ways, for example:

As an appetizer with drawn butter, lemon wedges and crusty bread
In crab cakes with remoulade or avocado sauce

Key Takeaways on Cooking Times for Crabs

Cook time varies based on size, type of crab, preparation method and quantity.
Check for doneness early using visual cues rather than relying solely on cook times.
It’s better to slightly undercook crab since the hot shell will continue cooking the meat.
Boiling, steaming and baking take 10-20 minutes depending on specifics. Grilling is faster.
Flaky texture, red shells and opaque flesh indicate crab is done cooking.
