Baked Crab Legs

Baked crab legs are the easiest way to eat and prepare Alaskan king crab. Oven-baked in butter and Old Bay seasoning, the tender, succulent meat slips right out of the shell when cracked! This delicious seafood meal is prepared in under 30 minutes and is steamed to perfection.

Similar to steaming, baking crab legs in a foil packet yields the juiciest result. Plus, the butter and Old Bay add even more richness to the crab meat.

One major hassle when it comes to eating crab: all the work that comes with it! Since the foil is wrapped around the crab leg clusters, it creates its own steaming oven. Then, the meat pulls away from the shell so perfectly.

You never have to worry about losing that delicious crab meat ever again!

The great thing about this recipe is it’s all done on a sheet pan (much like my sheet pan shrimp boil!), so this recipe can go from the oven right to the table!

This would be fun to do for a crowd of people, too. Spread this out on a large outdoor table for guests with a low country boil and some bread and you’ve got yourself a feast!

While cracking tools are recommended when shelling crab, you can easily use your hands and a pair of good kitchen shears to reach the meat, too.

Snow Crab vs. King Crab

If you’ve been around long, you know how passionate I am about sustainable seafood. Not only does it mean better quality seafood, but sustainable harvesting practices also help our ocean life and environment, too.

Here are a few quick tips for choosing crab legs:

  • Purchase wild-caught instead of farm-raised. This means the crabs were harvested from their natural environment, instead of “manufactured” from a farm and fed and pumped with who knows what to make them larger.
  • Look for harvesting locations in/around Alaska and Russia. King crab has a limited harvesting season and requires a cold water habitat, so they are most commonly found in and around the Bering Sea.

Snow crab is usually a little easier to find, so you can use snow crab as an alternative, but you will need to reduce the cooking time as snow crab is smaller. 

The main difference between snow crab and king crab is the size. King crab is larger with thicker legs and clusters than snow crab. However, their legs are shorter in length.

A snow crab’s meat is ideal for shredding and is commonly used to prepare crab cakes. Much like lobster, most people describe king crab as sweet, tender, and rich in flavor!

When it comes to reaching the meat, snow crab poses a little more of a challenge, but king crab legs provide large chunks of tender leg meat – perfect for hungry seafood lovers!

Through my research, I found this chart from Maine Lobster Now. They are an excellent resource for information on sustainable seafood and much more. Plus, they even deliver fresh seafood to your door! I’m definitely bookmarking them for future orders!

How to Cook King Crab Legs in the Oven

As an alternative to steaming, baked crab legs are a delicious way to prepare king crab. 

By preparing them in the oven, you eliminate the fuss and hassle of filling a giant boiler pot, boiling the water, timing the crab, and draining that huge vat of hot water. The oven method is much easier and less of a hassle overall.

First, I like to prepare the Old Bay and lemon butter sauce and set aside half of the mixture for dipping later. Then, use a pastry brush to baste the crab legs with the remaining butter and place the crab legs in the oven!

How long to bake crab legs

Depending on the thickness of the legs, crab legs take about 20-25 minutes in the oven at 400 degrees.

How to bake frozen king crab legs

If you are using frozen crab legs, follow the same instructions but increase the cooking time to 30 minutes.

How to Eat Crab Legs

This is the tricky and messy part. Sometimes you just have to get in there with your hands, but a good pair of kitchen scissors and “crackers” will make the job easier.

  1. Crack the leg away from the cluster. Then, crack at the joints to work with different sections.
  2. Working one section at a time, bend the pieces back and they should snap in half to expose the meat inside. 
  3. Slide the meat out, dip in butter and enjoy!

The meat from the cluster can easily be exposed by breaking apart with your hands or crackers. 

Tips for reheating, storing, and leftovers

  • To reheat crab legs in the shell, preheat your oven to 350F degrees, wrap the crab legs in foil and bake for 15-20 minutes. 
  • To reheat crab meat, add to a hot skillet and saute for 3 minutes or until warmed through. 
  • For easy storing, crack the crab and remove the remaining meat. Place in an airtight container and refrigerate for up to 3 days.
  • Crabmeat is also delicious served cold over a salad, mixed in pasta and pesto sauce, or prepared as a seafood salad.

I wonder if you use frozen snow crab legs, and bake for 20-25 minutes? Too long

@Anna Kate, just made it on the bbq tonight with snow crab and it turned out awesome about 15 mins. Turned one side of the bbq off so it would not burn.

Hi Kem,

This recipe has not been tested with snow crab legs or frozen crab legs, so attempt at your own risk. :) If I were to guess, I would reduce the cooking time by 10 minutes or so. Again, I haven't tested this recipe with snow crab or frozen crab so I can't say for sure. The notes in the recipe card on this post might be helpful as well.
