intro

Sweet, tender snow crab legs steamed and tossed in garlicky Old Bay butter, for a juicy, no-fuss coastal seafood feast perfect for sharing.

Ingredients

Frozen pre-cooked snow crab legs (thawed) 900 grams (2 lbs)
Unsalted butter 113 grams (1/2 cup / 1 standard stick)
Garlic (finely minced) 12 grams (4 medium cloves)
Old Bay seasoning 15 grams (1 tablespoon)
Kosher salt 3 grams (1 teaspoon)
Fresh flat-leaf parsley (chopped, divided) 6 grams (2 tablespoons)
Fresh lemon (cut into wedges) 100 grams (1 medium)
Water (for steaming) 240 ml (1 cup)

Steps

1

Prep the crab legs

Pat thawed pre-cooked snow crab legs dry with paper towels. Use sharp kitchen shears to cut a 2cm (3/4 inch) slit along the curved top of each leg shell to expose meat for easy eating, keeping shell segments connected at the joints to hold in moisture during steaming.

Step 1
step1:Prep the crab legs
2

Prep the steamer pot

Pour 240ml (1 cup) of cold water into a 5L (5.3 quart) stockpot, set a metal steamer basket inside, and confirm the water level sits 1-2cm below the basket base to avoid boiling crab directly. Bring water to a full rolling boil over medium-high heat, approximately 4 minutes.

Step 2
step2:Prep the steamer pot
3

Steam the crab legs

Arrange prepped crab legs in a loose single layer in the steamer basket, ensuring no segments are tightly packed to allow even steam circulation. Seal the pot tightly with a lid, reduce heat slightly to medium, and steam for exactly 5 minutes; overcooking will turn delicate crab meat tough and rubbery.

4

Make garlic butter

While crab steams, melt 113 grams (1/2 cup) of unsalted butter in a 1L (1 quart) small saucepan over low heat, about 2 minutes. Add 12 grams of minced garlic, 15 grams (1 tablespoon) of Old Bay seasoning, and 3 grams (1 teaspoon) of kosher salt, stirring constantly with a silicone spatula for 1 minute until garlic is fragrant and pale gold, taking care not to burn it. Remove pan from heat.

5

Toss crab in butter

Once crab legs finish steaming, use long metal tongs to carefully transfer all segments to a large 3L (3 quart) serving bowl. Pour 3/4 of the warm garlic butter over the hot crab legs, add 1 tablespoon (3 grams) of chopped parsley, and toss gently for 30 seconds to coat every shell evenly.

Garnish and serve

Drizzle the remaining garlic butter over the top of the crab, sprinkle with the remaining 1 tablespoon (3 grams) of chopped parsley, tuck lemon wedges around the bowl edge, and serve immediately while piping hot, with small seafood forks and crab crackers on the side.

Tips

1.Nearly all commercially sold snow crab legs are pre-cooked before freezing, so you only need to reheat them through—steaming longer than 6 minutes will turn the sweet, tender meat rubbery and dry.
2.Thaw frozen crab legs overnight in the refrigerator for even cooking; never thaw at room temperature for more than 1 hour to avoid harmful bacteria growth, and never refreeze previously thawed crab.
3.If you do not have a steamer basket, arrange crab legs on a wire cooling rack set inside the stockpot, as long as the legs do not come into direct contact with boiling water, which will make the meat waterlogged and bland.

Snow Crab Legs:Frequently Asked Questions

1.Do I have to thaw my frozen pre-cooked snow crab legs before steaming them?
You’ll get the juiciest, most even cook if you thaw them overnight in the fridge first, but if you’re short on time, you can steam them straight from frozen. Just add 3 to 4 minutes to your total steam time, and confirm they’re heated all the way through before tossing in the garlic butter sauce.
2.How long do I steam the crab legs to avoid tough, rubbery meat?
Since these are pre-cooked snow crab legs, you only need to steam them 4 to 6 minutes once your water hits a full, rolling boil. Oversteaming is the number one cause of rubbery crab—pull them as soon as you smell that briny, sweet aroma and the shells feel warm to the touch.
3.Can I use salted butter instead of unsalted butter for the sauce?
Absolutely, just adjust the added kosher salt to compensate. If using salted butter, cut the measured kosher salt in half first, then taste the sauce before tossing it with the crab. Remember, Old Bay already has noticeable sodium, so go light on extra salt to let the sweet, briny crab flavor shine.
4.How do I keep the garlic from turning bitter in the butter sauce?
Finely mince garlic by hand instead of using a press, which can release harsh, watery garlic compounds. Melt butter over low heat, add garlic, and sauté for just 30 to 45 seconds until fragrant—don’t let it turn deep golden, as burnt garlic will make the whole sauce taste bitter.
5.Do I need to crack the crab legs before I steam them?
You don’t need to crack them fully, but I recommend snipping a 1-inch slit along the top of each leg shell with sharp kitchen shears before cooking. This helps steam penetrate more evenly, and makes it far easier for guests to pull out tender meat once the legs are tossed in garlic butter.
6.What’s a good substitute if I don’t have Old Bay seasoning?
For every 1 ½ teaspoons of Old Bay the recipe calls for, mix 1 teaspoon paprika, ¼ teaspoon celery salt, ¼ teaspoon black pepper, a tiny pinch of cayenne, and a pinch of dry mustard. It’s not an exact replica, but it delivers that same warm, savory coastal spice profile that pairs perfectly with sweet crab.
7.How do I keep the crab legs warm for a shared party feast?
Once you toss the steamed legs in garlic butter, transfer them to a slow cooker set to the “warm” setting and cover with a lid. They’ll stay juicy and perfectly heated for up to 2 hours—just give them a quick toss every 20 minutes to keep the butter coating evenly distributed.
8.Can I make this recipe if I don’t own a steamer basket?
No special equipment required! Use a metal colander set inside a large stockpot, making sure the colander bottom doesn’t touch the boiling water, as a makeshift steamer. If you don’t have a fitting colander, use a wire rack over ½ inch of boiling water in a foil-covered roasting pan.
9.How many pounds of snow crab legs should I buy per person?
Plan for 1 to 1 ½ pounds of thawed snow crab legs per adult if this is your main dish. If you’re serving hearty sides like corn on the cob, coleslaw, or roasted potatoes, you can drop that to ¾ pound per person, but it never hurts to grab a little extra.
10.Can I make the garlic butter sauce ahead of time to cut down on day-of prep?
Definitely! Melt the butter, sauté the garlic until fragrant, stir in the Old Bay and kosher salt, then let it cool fully before storing in an airtight container in the fridge for up to 3 days. Gently reheat it over low heat right before tossing with freshly steamed crab.

OMG these garlic butter steamed crab legs were a total hit at our Sunday family dinner! My 7 and 9 year old usually turn up their noses at seafood, but they were begging for seconds before I even sat down. So easy to throw together too, 20 minutes total is perfect for our chaotic weeknights too, not just weekends! 10/10 will be making this for our next neighborhood potluck for sure.

Wait did you serve these with anything specific on the side? I’m making these for my husband’s birthday dinner next week and need side ideas!

So glad your family loved them! Great side picks are roasted corn on the cob, garlic bread, or a simple Caesar salad — they pair perfectly without taking away from the crab flavor!

Game changer! I always used to boil crab legs which made them watery and bland, but steaming them with that garlic butter? *Chef’s kiss* The butter soaks right in without making the meat soggy. Made these for my guys’ poker night last weekend and every single crab cluster was gone in 15 minutes flat. Will never make crab legs another way again.

Super easy recipe, tasted amazing! Only note is I added a tiny squeeze of lemon and a pinch of Old Bay to the garlic butter and it took it over the top. My only tiny complaint is I wish the recipe noted how much butter to use per pound of crab? I guessed and it worked out but would love a more specific measurement for when I make big meal prep batches!

Thanks so much for the feedback! Great call on the lemon and Old Bay, those are delicious add-ins. We’ve updated the recipe to note 1/2 cup of melted butter per 2 pounds of snow crab legs for perfect portioning every time!

As someone who grew up eating crab on the Washington coast, I’m super picky about how crab legs are prepared — and this recipe did NOT disappoint! The garlic is fragrant but not overpowering, the meat stays sweet and tender, no rubbery texture at all. Made these for my date night in last night and my boyfriend said it’s better than the seafood restaurant we went to for our anniversary.

Ooh date night idea stolen! Did you pair this with white wine? I’m thinking a crisp sauvignon blanc would go so good

Thrilled this lived up to your coastal standards! Quick tip for anyone cooking from frozen: add 2 extra minutes to the steam time and you’ll get perfect results, no thawing needed. And that sauvignon blanc pick is chef’s kiss!

SO good! I made these for my mom’s Mother’s Day brunch and everyone raved. I sprinkled a little fresh parsley on top for color and it looked like it came straight out of a fancy restaurant menu. No one believed it only took 20 minutes to make! Even my super picky grandma went back for a second helping.

Meal prep win! I steamed a big batch of these on Sunday, cracked all the meat out, and have been adding it to salads, pasta, and even scrambled eggs all week. The garlic butter flavor is so good it makes even boring work lunches feel fancy. 10/10, way cheaper than getting takeout seafood too.

Wait how do you store the leftover crab meat? I’ve never prepped crab ahead because I was worried it’d get rubbery in the fridge!

My granddaughter showed me this recipe last week and we made it together when she visited. Best crab legs I’ve had in years! We had so much fun cracking them open and dipping the meat in the extra garlic butter. Can’t wait to make these again when the whole family comes for the Fourth of July.

Aww that sounds like such a sweet memory! We’re doing a crab boil for Fourth too, I’m definitely swapping my usual boiled legs for this steamed garlic butter version

30 minutes ago

We love that this recipe turned into a fun grandparent-grandkid activity! It’s perfect for Fourth of July crowds, you can even double or triple the garlic butter batch easy to feed a big group.

First time ever making crab legs at home and I was so nervous I’d ruin them, but this recipe was so straightforward! They came out perfectly tender, the garlic butter was so flavorful, my roommate said it’s better than the seafood spot down the block that charges $40 a plate. Only tiny mishap was I spilled a little butter on my stove, but that’s 100% user error lmao.

just now

Yay, so proud of you for nailing crab legs on your first try! Butter splatters are just part of the fun of cooking seafood, no judgment at all. So glad you and your roommate enjoyed!
