There’s something about snow crab legs that feels special, right? Maybe it’s because we don’t make them every week, or maybe it’s the ritual of cracking them open and dipping those sweet, tender pieces into melted butter. Whatever it is, I’m here to tell you that cooking snow crab legs at home is so much easier than you might think—and honestly, they turn out just as good (if not better!) than at restaurants. If you love seafood as much as I do, you’ll also want to check out my Maine Lobster Roll recipe!
I’ll never forget the first time I attempted crab legs at home. I was hosting a little dinner party, feeling ambitious, and I stood in front of the seafood counter absolutely convinced I’d mess them up somehow. The fishmonger smiled kindly and said, “You literally can’t ruin these.” And you know what? He was right. Snow crab legs are almost foolproof, and today I’m going to show you exactly how to make them perfectly every single time.
The best part? You only need about 10 minutes from start to finish. These are pre-cooked when you buy them (they’re flash-frozen right after being caught), so you’re really just reheating them gently and infusing them with a little extra flavor. Simple, impressive, and absolutely delicious.

Why You’ll Love This Recipe
Snow crab legs have become my go-to when I want something that feels indulgent but doesn’t require actual cooking skills. Seriously—if you can boil water, you can make incredible crab legs. They’re perfect for those nights when you want to treat yourself, celebrate something special, or just break out of the usual dinner routine.
I love that they feel fancy but come together faster than most weeknight dinners. Plus, there’s something wonderfully interactive about eating them—cracking the shells, pulling out the meat, dunking everything in butter. It turns dinner into an experience, you know? Jake and I will put on some music, spread out newspaper on the table, and just enjoy the process. The cats (Basil and Sage) are always very interested in the proceedings, naturally.

Choosing Your Snow Crab Legs
When you’re at the store, you’ll typically find snow crab legs in the frozen seafood section, though some stores carry them fresh at the counter. Here’s what I look for: clusters that feel heavy for their size (that means they’re full of meat), with shells that look intact and not broken. The color should be bright reddish-orange.
Don’t stress too much about whether they’re “colossal” or “jumbo”—snow crab legs are generally smaller and more delicate than king crab, and that’s exactly what makes them so sweet and tender. I usually grab about 1 to 1½ pounds per person because, let’s be honest, it’s hard to stop once you start.
If you’re buying frozen (which is perfectly fine!), let them thaw in the refrigerator overnight. If you forgot to thaw them—been there!—you can run cold water over them for about 30 minutes. Just don’t use hot water or the microwave, as that can make the meat rubbery.
Two Simple Methods: Boiling or Steaming
I’m giving you both methods here because honestly, they both work beautifully. Boiling is slightly faster and infuses the crab with flavor from the cooking liquid, while steaming is a bit more gentle and keeps the meat incredibly tender. I switch between the two depending on my mood (and how many pots are clean, if we’re being real).
The Boiling Method
This is my weeknight go-to. Fill a large pot about two-thirds full with water and bring it to a rolling boil. I like to add a generous amount of salt (think ocean water—about ¼ cup for a big pot), along with a halved lemon, a few bay leaves, and sometimes a splash of Old Bay seasoning if I’m feeling fancy. These aromatics aren’t required, but they add such a lovely subtle flavor.
Once the water is boiling vigorously, gently add your crab legs. You’ll want to bend them slightly at the joints to fit them in—don’t worry, they’re more flexible than they look. Bring the water back to a boil, then reduce the heat to a simmer and cook for 4-5 minutes. That’s it! You’ll know they’re ready when they’re heated through and the shells are bright red-orange.
The Steaming Method
For steaming, fill a large pot with about 2 inches of water and add the same aromatics (salt, lemon, bay leaves). Bring it to a boil, then place a steamer basket or metal colander inside the pot—make sure it’s not touching the water. Arrange the crab legs in the basket, cover tightly with a lid, and steam for 5-6 minutes.
The steam circulates around the legs, heating them gently and keeping them incredibly moist. I love this method when I’m making a lot of crab legs because I can stack them without worrying about uneven cooking.
The Butter Situation (Very Important)
Let’s talk about the butter, because this is where the magic happens. While your crab legs are cooking, melt about ½ cup of butter per pound of crab. I usually do this in a small saucepan over low heat, and I like to add a squeeze of fresh lemon juice and a pinch of garlic powder. Sometimes I’ll throw in a tiny sprinkle of Old Bay or even just a crack of black pepper.
Pour the melted butter into small individual bowls for dipping—this way everyone gets their own and you avoid the awkward double-dipping situation. Keep the remaining butter warm on the stove if you want refills (and trust me, you will).
How to Eat Snow Crab Legs Like a Pro
Here’s what I do: Grab a leg and locate the joints. Use your hands or kitchen shears to cut through the shell at the joints, then gently pull the pieces apart. The meat should slide right out—if it resists, you can use a small fork or even a seafood pick to coax it out.
Some people like to use those fancy crab crackers, and those are great if you have them, but honestly? Your hands work just fine for snow crab legs since the shells are thinner and more delicate than king crab. I keep a roll of paper towels on the table and embrace the messiness. It’s part of the fun.
The sweet, delicate meat is worth every bit of effort. Dip each piece generously in the butter, take a bite, and try not to smile. It’s basically impossible.
What to Serve with Crab Legs
I like to keep sides simple so the crab remains the star. My usual lineup includes:
- Crusty bread for soaking up all that garlicky butter
- Corn on the cob (boiled or grilled with butter)
- Simple green salad with a lemony vinaigrette
- Roasted potatoes or a baked potato with sour cream
- Coleslaw for a refreshing, crunchy contrast
And of course, plenty of lemon wedges for squeezing over everything. The brightness cuts through the richness of the butter and makes every bite pop.
Storage & Leftovers
If by some miracle you have leftover crab (this rarely happens at my house), you can store the meat in an airtight container in the fridge for up to 3 days. I like to pick the meat out of the shells first—it makes it much easier to use later.
Leftover crab meat is incredible in so many ways: tossed with pasta and lemon (like my Lemon Butter Garlic Shrimp Pasta but with crab!), folded into an omelet, mixed into a seafood salad, or piled onto a toasted bun with mayo and celery for an amazing crab roll. Don’t let a single delicious bite go to waste!
My Encouragement to You
If you’ve been intimidated by cooking seafood at home, let snow crab legs be your gateway. They’re genuinely one of the easiest, most forgiving things you can make, and the payoff is enormous. You’ll feel like a culinary genius with minimal effort—which is exactly my kind of cooking.
I really hope you’ll give this a try, especially for your next celebration or “just because” dinner. There’s something wonderful about cracking into crab legs at your own table, taking your time, and savoring every sweet, buttery bite. If you make these, I’d absolutely love to see!

Happy cooking (and cracking), friends!

Pro Tips 💡
- Don’t overcook: Since snow crab legs are pre-cooked, you’re just reheating them. Overcooking makes the meat tough and rubbery. Stick to the 4-6 minute range.
- Kitchen shears are your friend: They make cutting through the shells so much easier than trying to crack them. I keep a dedicated pair just for seafood.
- Keep butter warm: Set your butter bowls on a heating pad or in a warm water bath so they stay melted throughout the meal.
- Save the shells: If you’re feeling ambitious, you can use leftover crab shells to make an incredible seafood stock. Just simmer them with aromatics for about 30 minutes.
Variations 🔄
- Garlic Butter: Add 3-4 minced garlic cloves to your melted butter for extra flavor
- Cajun Style: Use Cajun seasoning in the water and add hot sauce to your butter
- Herb Butter: Stir in fresh chopped herbs like parsley, dill, or tarragon
- Asian-Inspired: Skip the butter and serve with a dipping sauce of soy sauce, rice vinegar, ginger, and sesame oil
