Follow these helpful tips and techniques for boiled crab leg success every time.
Visual Cues
Change in Color
The shells of properly cooked crab legs will turn from a pale white/grey to a vibrant reddish-orange hue. This color transformation indicates the crab meat has been sufficiently heated. Check that the joints and ends of the legs have taken on a deep, rich color. Any parts that still look pale likely need a bit more time.
Opaque, White Meat
Use a fork to gently separate the shell at a joint. The meat inside should be opaque and white with a very slight tinge of pink rather than translucent. Pearly white, opaque meat means the crab is cooked through.
Texture and Firmness
Perfectly cooked crab meat will be firm yet still somewhat pliable when poked, not mushy. Gently press a leg segment between your fingers. It should feel dense, with a pleasant juicy bounce. If it seems overly hard or rubbery, it is overcooked.
Temperature Method
For precise doneness use an instant-read thermometer. Insert the probe into the thickest part of a crab leg reaching the center of the meat. It should register
- 145°F (63°C) for snow crab and king crab
At this internal temp, harmful bacteria has been eliminated and the texture of the meat will be ideal.
Timing
While less reliable than the above methods, a general timing guideline is:
- Snow crab legs: 3 to 5 minutes
- King crab legs: 4 to 6 minutes
- Add 2 to 3 minutes if cooking frozen crab legs
But always verify doneness with a thermometer or visual tests. Timing varies depending on size of legs, amount in pot, and other factors.
Aroma
A properly cooked crab leg will release a light ocean-like aroma when opened, not an overly “fishy” smell. A strong scent indicates overcooking.
Serving Suggestions
Once boiled to perfection, here are some tasty ways to serve crab legs:
- Dip pieces of meat in melted butter or lemon butter.
- Sprinkle with fresh lemon juice and parsley.
- Pair with classic sides like coleslaw or corn on the cob.
- Add to pasta, risotto or salad for a crab and grain bowl.
- Garnish a seafood platter with crab legs alongside shrimp and lobster.
With these handy tricks for determining when boiled crab legs are done, you’ll be able to enjoy restaurant-quality results at home. Listen for the shell’s snap, check for opaque meat, use a thermometer, and scent the ocean breeze aroma. Your patience will be rewarded with tender, juicy, flavorful crab that steals the show!
How To Cook Crab Legs
There are several methods you can use to cook crab legs. Boiling is the most common, but you could also steam or grill them.
I like to make the clarified butter while the crab cooks so everything is done together. The steps below talk you through making both the butter and crab at the same time.
How To Boil Snow Crab Legs
See the recipe card below for full, detailed instructions
This method is my go-to and the one I include in detail in the recipe card below. In this section, however, I’ll include tips for steaming and grilling as well.
- Season a large pot of boiling water with salt and Old Bay.
- While the water is coming to a boil, start melting butter in a small saucepan over medium-low heat. Cook the butter until it gets foamy, it only takes a minute. Remove the pan from the hot burner and let the butter hang out in the pan for 5 minutes while the crab cooks.
- Next, place the crab legs into the boiling water. (I use tongs!) Let the crab boil for 5 to 6 minutes until it’s warmed and fragrant.
- Then, use tongs to remove the crab from the pot and place on dinner plates.
- Use a spoon to remove any solids floating on top of the butter. Then pour the butter into two small bowls.
- Sprinkle a little more Old Bay over the crab legs (optional but I like to do this) and then serve immediately with the clarified butter and lemon wedges.
