How to Cook Crab Legs at Home

Name: How to Cook Crab Legs at Home
Ingredients: 1 inch water; to taste salt; splash water

Crab legs are already cooked when you buy them, so you're really just reheating. Steam them for 4-6 minutes, boil for 3-4 minutes, or bake at 375°F for 7-10 minutes. The shells will turn bright orange-red when properly heated through.

1 inch water
to taste salt
splash water

Step by step

Thaw the crab legs if frozen. Move them from freezer to refrigerator 8-12 hours before cooking. If you're short on time, run cold water over them for 30 minutes. Never use warm water or the microwave.
Choose your cooking method. Steaming keeps them most tender, boiling is fastest, and baking works well for large quantities. All three methods work equally well for reheating.
Prepare your cooking setup. For steaming: Fill a large pot with 1 inch of water and insert a steamer basket. For boiling: Fill a large pot with salted water. For baking: Preheat oven to 375°F and get a baking dish ready.
Cook the crab legs. Steam for 4-6 minutes once water boils. Boil for 3-4 minutes. Bake for 7-10 minutes wrapped in foil with a splash of water. The shells turn bright orange-red when ready.
Serve immediately. Crack the shells with kitchen shears or a crab cracker. Provide melted butter, lemon wedges, and napkins. The meat should be hot and pull out easily from the shell.

Tips & troubleshooting

Don't overcook - the meat becomes rubbery. Crab legs are done when hot throughout, not when cooked through.
Kitchen shears work better than crab crackers for cutting shells. Cut along the length of each segment.
Save the shells and any liquid for making seafood stock later.
Buy from a reputable fishmonger and ask when they arrived. Fresher crab legs have tighter shells.
King crab legs need slightly longer cooking times than snow crab due to their thicker shells.

Variations

Garlic Butter Steam. Add minced garlic and butter to the steaming water for extra flavor that infuses the meat through the shells.
Old Bay Boil. Season the boiling water heavily with Old Bay seasoning or your favorite seafood seasoning blend.
Wine Steam. Replace half the steaming water with white wine for a more refined flavor.
Grilled Crab Legs. Split the shells lengthwise, brush with garlic butter, and grill for 4-5 minutes over medium heat.

Questions

How do I know if crab legs are fully heated?: The shells turn bright orange-red and the meat is steaming hot when you crack them open. If you have a thermometer, the internal temperature should reach 145°F.
Can I cook frozen crab legs without thawing?: Yes, but add 2-3 extra minutes to your cooking time. The results are better if you thaw them first, but it's not necessary if you're pressed for time.
Why is my crab meat sticking to the shell?: Usually means they're overcooked or were frozen and thawed multiple times. Sometimes older crab legs do this too. Next time, cook for less time and buy from a different source.
What's the difference between king crab and snow crab legs?: King crab legs are much larger with thicker shells and sweeter meat. Snow crab legs are thinner, cook faster, and have a more delicate flavor. Both cook the same way.
How much should I buy per person?: Plan for about 1-2 pounds per person for king crab legs, or 1/2 to 1 pound per person for snow crab legs, depending on what else you're serving.
