How to Cook Crab: Methods, Times & Recipes
Crab cook in about 4-6 minutes and are done when heated all the way through. The most popular methods are steaming, boiling, baking or grilling. Below are step-by-step guides for every way to cook crab, with exact times and temperatures.
The best way to cook crab
You can cook crab by steaming, boiling, baking or grilling. Most crab legs are sold pre-cooked, so you are really just reheating them — stop as soon as they are hot to avoid drying out the meat.
There is no single “best” method — it depends on the cut and the result you want. Quick, high-heat methods like searing and grilling give colour and a little char, while gentler methods like baking, steaming and poaching keep crab moist and forgiving. Each guide below walks through one method in full, with the exact timing and doneness cues for it.
How to tell when crab is done
The single most important thing with crab is not to overcook it. Seafood goes from perfectly done to tough and dry in a matter of seconds, and it keeps cooking from residual heat even after it leaves the pan. Watch for the visual cue — crab are ready when heated all the way through — and take them off the heat a touch before they look completely done so carry-over heat can finish the job.
Buying and storing Crab
Raw crab should be firm and smell faintly of the sea, with no strong fishy odour. Refrigerate and use within one to two days, or keep frozen for several months and thaw overnight in the fridge. Live or freshly cooked crab is best cooked or eaten the day you buy it; once cooked, store it covered in the fridge and finish it within a couple of days.
