Sous Vide Snow Crab Legs

I am not a crab specialist. Crab connoisseurs would watch me crack crab legs and dig out the meat and probably giggle. Things fly everywhere. But I get the job done. And I absolutely love the final result. I could eat crab all day. That usually means grilling them. Or boiling them. This time, though, I tried sous vide snow crab legs. Let me tell you, this is my go-to way for perfect crab legs from here on. It’s easy, quick, and the result is deliciously fantastic!

Sous Vide Snow Crab Legs

Flavor-Packed Crab Greatness

The flavor in these sous vide snow crab legs is fantastic. At least in my case, I added butter (and lots of it) and Old Bay seasoning (and lots of that too!). This is not the time (in my opinion) to be shy with either one. I want messy, crazy-good crab and that’s exactly what I got. I cannot wait to make these again.

Remember, the crab legs are already cooked (steamed, actually). You’re just warming them up and adding flavor. And making sure you’re not losing any flavor like you would if you just boil them.

You can use this same recipe for larger crab legs, too. I’d add some more time to warm them up, so I’d start with 45 minutes and maybe go as long as an hour.

I use an Anova sous vide cooker. It’s my immersion circulator workhorse!

  • 1-2 pounds snow crab legs thawed
  • 2 tablespoons unsalted butter
  • ¼ cup Old Bay seasoning more or less, to taste. optional
  • dipping sauces clarified butter, cocktail sauce, whatever you prefer!
  • lemon for serving, if desired


  • Heat your water to 140 F using your immersion circulator.
  • Place the crab legs into a large (1 gallon) resealable bag. You may have to separate the legs at the joints to get them to fit. You want them to all fit in the bottom of the bag.
  • Add enough water to the bag to just cover the legs.
  • Lower the bag into the warmed water. Use a clip to clamp the bag to the side of your container, keeping the bag open. You do not need to vacuum seal the bag or remove any air from it, just make sure that the legs are below the water line.
  • Heat the legs for 30-45 minutes or until heated through.
  • Remove and drain the bag into a colander.
  • Let cool slightly before serving.
