intro

Succulent sweet crab legs coated in rich garlic butter, steamed to tender perfection for a juicy, indulgent seafood feast that requires minimal prep and cook time.

Ingredients

Thawed shell-on Alaskan king crab legs 1.3 kg (approx 3 lbs)
Unsalted butter 113 g (1 stick / ½ cup)
Fresh garlic, minced 30 g (approx 8 medium cloves)
Old Bay seasoning 15 g (1 tablespoon)
Kosher salt 5 g (1 teaspoon)
Fresh lemon, cut into wedges 200 g (2 medium whole lemons)
Fresh flat-leaf parsley, finely chopped 5 g (2 tablespoons)

Steps

1

Fill a large 8-quart stockpot with 480 ml (2 cups) of cold tap water, stir in 5 g (1 teaspoon) of kosher salt, and bring to a rolling boil over medium-high heat (approx 190°C/375°F stovetop setting). Place a perforated metal steamer basket inside the pot, confirming the water level sits 2.5 cm (1 inch) below the basket base so crab legs do not get submerged.

Step 1
step1:
2

Rinse thawed crab legs under cool running water for 30 seconds to brush off any residual ice crystals or loose shell fragments, then arrange them in a loose, single layer in the steamer basket. Seal the pot tightly with a lid, reduce heat to medium (approx 150°C/300°F stovetop setting) to maintain consistent steam, and cook for 8 minutes until shells turn bright opaque red and internal meat temperature reaches 74°C (165°F) measured with a food thermometer.

Step 2
step2:
3

While the crab steams, place 113 g (1 stick) of unsalted butter in a small 1-quart saucepan over low heat (approx 120°C/250°F stovetop setting) to melt fully. Add 30 g of minced garlic and 15 g (1 tablespoon) of Old Bay seasoning, stirring continuously with a wooden spoon for 2 minutes until garlic is pale golden and fragrant, taking care not to let the garlic turn dark brown or burn.

Step 3
step3:
4

Turn off the stovetop heat for both the stockpot and sauce pan. Use 30 cm (12-inch) long kitchen tongs to carefully lift the steamed crab legs from the basket, letting excess steam drip off for 2 seconds per leg, and arrange them on a large 35 cm (14-inch) serving platter. Drizzle ¾ of the warm garlic butter evenly over the hot crab legs, turning each leg once with tongs to coat the entire shell surface.

Step 4
step4:
5

Sprinkle the butter-coated crab legs evenly with 5 g (2 tablespoons) of finely chopped fresh parsley, then tuck the 200 g of cut lemon wedges around the edges of the platter. Pour the remaining ¼ of the garlic butter into two 60 ml (2 oz) small ceramic ramekins to use as dipping sauce, and serve immediately alongside seafood crackers and small seafood forks for extracting meat.

Tips

1.If using unthawed frozen crab legs, add 4 minutes to the steaming time; never thaw crab legs in hot water, as this will make the delicate meat mushy and leach out sweet flavor.
2.For extra bright, aromatic flavor, replace 120 ml (½ cup) of the steaming water with dry white wine or fresh lemon juice to infuse the crab meat as it cooks.
3.For richer, more flavorful bites, use a seafood cracker to gently crack each crab leg shell before drizzling with butter, so the seasoned garlic butter seeps directly into the meat instead of only coating the outer shell.

Crab Legs:Frequently Asked Questions

1.Can I use frozen, unthawed crab legs instead of thawed ones for this recipe?
While thawed crab legs cook more evenly and absorb garlic butter better, you can use unthawed frozen legs in a pinch. Add 2 to 3 extra minutes of steaming time, and confirm the thickest part of the leg reaches 145°F internally to ensure they’re fully heated through before tossing with the seasoned butter.
2.How do I prevent the crab meat from turning rubbery while steaming?
Rubbery crab almost always comes from overcooking, which happens quickly with delicate shellfish. Keep your steamer water at a gentle rolling boil (not a violent, raging boil) and stick to 5 to 7 minutes of total cook time for thawed king crab legs. The shells will turn bright opaque red when done, with meat that pulls easily from the shell.
3.Can I swap salted butter for the unsalted butter listed in the ingredients?
Absolutely, if that’s what you have on hand. Just cut the measured kosher salt in half, and taste the garlic butter sauce before tossing it with the crab to avoid over-salting. Keep in mind Old Bay seasoning already contains a fair amount of salt, so err on the light side with extra seasoning when using salted butter.
4.What’s the easiest way to crack cooked crab legs without shredding the tender meat?
Start by using a seafood cracker to gently crack the thick knuckle and joint sections, taking care not to fully crush the shell. Then run a small seafood fork (or even a regular dinner fork) down the length of the split shell to pull whole, intact pieces of meat out without shredding them into tiny bits.
5.Should I add anything other than water to the steamer pot for extra flavor?
You don’t have to, but adding a splash of light beer, a couple lemon wedges, or an extra pinch of Old Bay to your steamer water will infuse the crab with subtle, bright flavor as it cooks. Just keep the crab elevated in a steamer basket above the liquid, so they steam rather than boil.
6.How should I store leftover garlic butter steamed crab legs?
Keep leftover crab legs in their shells (to lock in moisture) in a sealed airtight container in the refrigerator for up to 3 days. For the best texture when reheating, steam them for 2 to 3 minutes until just warmed through. Skip the microwave, as it will quickly turn the delicate crab meat tough and rubbery.
7.Can I make this recipe with snow crab legs instead of Alaskan king crab legs?
Definitely! Snow crab legs are thinner and smaller than king crab legs, so cut your steaming time down to 3 to 5 minutes for thawed snow crab legs to avoid overcooking. The garlic butter and Old Bay seasoning pairs perfectly with snow crab’s slightly sweeter, flakier meat, so no other recipe adjustments are needed.

OMG these garlic butter steamed crab legs were the star of our family dinner last night! I was nervous they’d be tricky since I’ve only ever boiled crab legs before, but this method was so easy and the garlic butter flavor was insane. My husband went back for thirds, no joke.

Wait did you use snow crab or king crab legs for this? I’m grabbing supplies for my birthday dinner this weekend and can’t decide!

yesterday

So glad your family loved them! Both snow and king crab legs work beautifully with this method – if you’re feeding a crowd, snow crab is usually a little more budget-friendly, but king crab feels extra special for a birthday!

Total game changer for weeknight seafood nights! 25 minutes total cook time? I didn’t believe it at first, but I pulled this off after soccer practice with zero stress. My kids dipped every bite in extra garlic butter and didn’t even complain about seafood for once. SO good.

Love hearing this! We designed this recipe specifically to be doable on busy weeknights, so it makes us so happy it worked for your post-practice dinner. Pro tip: toss a little Old Bay in the butter if your crew likes a little extra zing next time!

I threw these on the steamer rack for our backyard potluck last weekend and people were hovering around the pot waiting for them to finish. The garlic butter is so rich but doesn’t overpower the sweet crab meat. 10/10, will be making this for every summer cookout from now on.

Made this for date night in with my partner and we both agreed it was better than the crab legs we got at that fancy seafood spot in Manhattan last month! The only tweak I made was adding a squeeze of fresh lemon and a pinch of red pepper flakes to the butter. Perfect, no notes.

3 days ago

Oh the red pepper flakes sound chef’s kiss! I’m making this for my anniversary dinner next week, did you serve it with anything on the side?

2 days ago

That lemon and red pepper flake tweak is one of our favorite variations too! For sides, roasted corn on the cob and crusty bread to soak up the extra butter are always a hit.

I’ve lived in Florida my whole life and have had my fair share of crab legs, and this recipe knocked it out of the park. Steaming them instead of boiling keeps the meat so tender, and that garlic butter seeps into every little crack? Unreal.

Right?! I always used to boil mine and they’d get so watery and bland. Steaming is a total game changer like everyone says!

Super easy recipe for anyone who’s intimidated by cooking seafood at home! I was worried I’d overcook the crab and make it rubbery, but the timing was spot on. The meat pulled out perfectly in whole chunks every time.

Followed the recipe exactly for my anniversary dinner and my fiancé kept asking where I ordered takeout from! The garlic butter smelled so good while it was steaming that our neighbor texted to ask what we were cooking, ha. Will absolutely be making this again.

That’s the highest compliment when a neighbor texts to ask about the smell! So glad it made your anniversary dinner feel special – congrats on the upcoming wedding!

Wait, can I make this without a fancy steamer basket? I live in a tiny mountain cabin and have very limited kitchen gear, but I’ve been craving crab legs forever.

I did this last week with a metal colander set inside a big stock pot with a lid, worked perfectly! Just make sure the water doesn’t touch the bottom of the colander.

Great tip from LazySundayCook! You don’t need a special steamer at all – a colander, metal strainer, or even a wire rack set in the bottom of a deep pot works just as well for this recipe.

Made these for my birthday dinner this weekend with snow crab like the admin suggested, and they were a massive hit! We had crusty bread to dip in the leftover garlic butter and not a single drop went to waste. My whole family is already asking when I’ll make them again.

Happy belated birthday! So glad the snow crab worked out for your celebration – that crusty bread trick is non-negotiable in my house, no sense wasting that delicious garlic butter!

I brought these to a neighborhood potluck a few days ago and the platter was empty in 10 minutes flat. I even had three people text me for the recipe before I left! Easy, delicious, always a crowd pleaser. Can’t beat that.

Perfect lazy Sunday meal! I picked up pre-thawed crab legs from the grocery store on my way home from church, whipped up the garlic butter, and had lunch on the table in 20 minutes. No fuss, all flavor. My roommate said it’s the best thing I’ve ever cooked.

Wait pre-thawed crab legs are a game changer! I’ve been buying frozen and forgetting to thaw them ahead of time, I’ll have to grab the pre-thawed ones next time I make this.

I’m in charge of the main dish for our big family reunion next month, and I’m thinking of making a huge batch of these. Has anyone scaled this recipe up for 20+ people? Any tips?

5 days ago

I made 15 pounds for a family reunion last month! Just work in batches so you don’t overcrowd the steamer, and keep the finished crab legs in a warm cooler lined with foil while you cook the rest. Worked like a charm.

3 days ago

That batch cooking tip from TexanBBQGuy is spot on! Just scale the garlic butter up proportionally (we do 1 tbsp butter + 1 clove garlic per pound of crab legs) and you’ll be all set for the reunion. It’s always a crowd favorite!

I usually smoke all my seafood, but it was too hot to fire up the smoker last weekend so I gave this steamed version a shot. Let me tell you, that garlic butter is so good I might even prefer this to my smoked crab legs. Don’t tell my BBQ buddies I said that, though.

As a college student with basically zero cooking skills, I was shocked how easy this was! I made it in my tiny dorm kitchen with a cheap pot from the dollar store and it turned out amazing. My dorm floor mates all congregated in the hallway when they smelled the garlic butter, ha.

This is so awesome to hear! This recipe is perfect for beginner cooks because it’s so forgiving and doesn’t require fancy equipment. We’re impressed you pulled it off in a dorm kitchen – great work!

My husband and I made this for our first empty nester dinner after our youngest moved off to college, and it felt like a fancy restaurant meal right at home. The only issue is we made way too much – can you reheat leftover steamed crab legs okay?

yesterday

I reheat leftovers by steaming them for 2-3 minutes just like the recipe, they don’t get rubbery at all! Just don’t microwave them, that makes the meat weirdly tough.

2 hours ago

Love that you two got to enjoy a nice fancy dinner at home! As SpiceItUpSam said, quick re-steam is the way to go for leftovers – microwave is a no-go, it’ll make the meat tough and rubbery. You can also pick the leftover crab meat and toss it in pasta or salads for an easy meal the next day!

I added a big pinch of Cajun seasoning, a squeeze of lime, and a handful of chopped parsley to the garlic butter and oh my gosh, it was next level. The recipe is perfect as written, but that little extra spice made it taste like something from a beachside seafood shack. 10/10.

That Cajun seasoning and lime twist sounds incredible! We love seeing all the fun variations people come up with – we might have to test that version for ourselves soon!

Got some fresh Dungeness crab legs from the fisherman’s wharf over the weekend and used this recipe, and it was the best meal I’ve had all month. The simple garlic butter let the sweet, fresh crab flavor shine without overpowering it. So simple, so perfect.

Dungeness crab with this garlic butter sounds like absolute heaven! I can never find fresh Dungeness out here in Chicago, I’m jealous!

I finally caved and bought king crab legs to make this last night, and wow. I know king crab is pricy, but it was 100% worth it for a special treat. I served it with roasted potatoes and asparagus, and my whole family was raving. Will definitely be a special occasion staple in our house from now on.

just now

I’ve tried so many crab leg recipes over the years that are either overcomplicated or turn out rubbery, and this one is easily the best. The steam time was exact, the garlic butter ratio was perfect, and cleanup was a breeze. I’ve already saved this to my permanent recipe folder!
