Red Lobster Crab Legs Recipe (Steamed Snow Crab Copycat)

I have been chasing the Red Lobster crab legs experience for years. You know the one – a giant pile of snow crab clusters, perfectly steamed until the shells turn that gorgeous coral-orange, served alongside a ramekin of warm garlic butter that you absolutely cannot stop dipping into. I finally cracked the code after testing this recipe no fewer than six times in my kitchen, and I am not exaggerating when I say my husband now requests this instead of going out. The secret is two things: Old Bay seasoning in the steam water to infuse the meat from the outside in, and a proper garlic butter sauce with minced fresh garlic (not the jarred stuff) that you pull off the heat at exactly the right moment.

The best news about this copycat recipe is that snow crab legs sold at most grocery stores are already pre-cooked and frozen, which means you are really just reheating them while adding flavor. That makes this one of the most forgiving impressive-looking dinners you can put on the table. Total time is about 15 minutes from water boiling to plate, and the result looks like you spent an entire evening cooking. Perfect for date night, holidays, or any time you want to feel a little fancy without leaving the house.

Why You’ll Love This Recipe

• Ready in just 15 minutes – faster than driving to Red Lobster and waiting for a table
• Fraction of the restaurant price – feed four people for what one entree costs at the chain
• Old Bay in the steam water seasons the meat all the way through, not just the surface
• The garlic butter sauce tastes exactly like the restaurant version and takes about 3 minutes to make
• Works with frozen crab legs straight from the freezer – no advance thawing required

About This Red Lobster Favorite

Red Lobster has been serving snow crab legs since the chain launched in the 1960s, and the dish has become one of their most iconic menu items for good reason. They serve snow crab clusters – those long spindly legs bundled together at the body – steamed until heated through, then brought to the table with a side of melted garlic butter and lemon wedges. The whole experience is intentionally casual and messy in the best way possible, with guests cracking shells and pulling out that sweet, delicate meat with their fingers. Snow crab is prized for its slightly sweet flavor and tender texture, which is notably more delicate than the bolder taste of king crab. The clusters are typically sold frozen and pre-cooked, meaning they have already been steamed or boiled once before freezing. This is actually great news for home cooks because it means you cannot really undercook them – you are simply reheating and adding flavor. Red Lobster seasons their cooking liquid and serves the crab with their signature garlic butter, which is the two elements this copycat recipe nails exactly. The result is a festive, crowd-pleasing seafood dinner that feels like a special occasion even on a Tuesday.

Ingredients

For the crab legs

• 3 lbs frozen snow crab leg clusters (or king crab legs for an upgrade)
• 4 cups water for steaming
• 1 lemon, halved
• 2 tablespoons Old Bay seasoning
• 4 cloves garlic, smashed
• 2 bay leaves

For the garlic butter dipping sauce

• 1 cup (2 sticks) unsalted butter
• 6 cloves garlic, minced
• 2 tablespoons fresh lemon juice
• 1 teaspoon Old Bay seasoning
• 1/4 teaspoon salt
• 1 tablespoon fresh parsley, finely chopped
• 1 tablespoon white wine (optional, adds depth)

For serving

• Lemon wedges for garnish
• Extra melted butter in ramekins for the table
• Kitchen shears for cracking shells
• Seafood picks or small forks for pulling out meat
• A big stack of paper towels – this is a glorious mess

Ingredient Substitutions

• King crab legs – larger, more dramatic presentation, more expensive but absolutely worth it for a special occasion
• Dungeness crab – whole crabs steamed 15-18 minutes, crack at the table the same way
• Fresh live snow crab – steam whole for 12-14 minutes instead of 8-10
• Instant Pot method – add 1 cup water, steam rack, cook on High Pressure for 4 minutes (from frozen) or 2 minutes (from thawed)
• Oven baked method – brush with butter, wrap tightly in foil, bake at 400 degrees F for 15 minutes

Equipment You’ll Need

• Large stockpot (at least 8-quart) with a steamer basket or insert
• Tongs for safely lifting hot crab legs
• Kitchen shears – the absolute best tool for cracking snow crab shells
• Small saucepan for the garlic butter sauce
• Small ramekins or dipping cups for individual butter portions

Step-by-Step Instructions

1. Prepare the steamer. Fill your large stockpot with 4 cups of water and set it over high heat. Add the lemon halves (squeeze them in before dropping them in the pot), Old Bay seasoning, smashed garlic cloves, and bay leaves. This seasoned steam is what infuses flavor into the crab meat as it heats through – do not skip this step or you will end up with bland crab no matter how good your butter sauce is. Bring the water to a full rolling boil before adding the crab.
2. Steam the crab legs. Place your steamer basket or insert above the boiling water – you want the crab sitting over the steam, not submerged in the water. Arrange the crab leg clusters in the basket, folding or bending them as needed to fit. Cover the pot tightly with a lid. Steam for 8-10 minutes if the crab legs are already thawed, or 12-15 minutes if cooking directly from frozen. The crab is done when the shells are bright coral-orange and the meat is heated all the way through. Frozen pre-cooked crab does not need to reach any specific internal temperature – you are just reheating it.
3. Make the garlic butter sauce. While the crab steams, melt the butter in a small saucepan over medium-low heat. Add the minced garlic and cook for about 1 minute, stirring constantly – you want the garlic to turn fragrant and just barely golden, not brown. Pull the pan off the heat and stir in the lemon juice, Old Bay, salt, parsley, and white wine if using. The residual heat finishes the garlic without burning it. Pour the sauce into individual ramekins for serving so each person gets their own warm butter.
4. Serve immediately. Use tongs to transfer the hot crab legs to a large platter or directly onto paper-lined sheet pans in the center of the table. Serve with the garlic butter ramekins, extra lemon wedges, kitchen shears for cracking, and seafood picks for extracting meat. Crab cools down quickly, so get everyone to the table before you plate. The best way to eat snow crab is to snip along the underside of each leg section with shears, then peel back the shell to reveal the meat in one clean piece.

Pro Tips from My Kitchen

• Almost all snow crab sold in US grocery stores is pre-cooked and frozen – you are reheating, not raw-cooking, which means it is very hard to make someone sick from undercooking
• The Old Bay in the steam water is not just for show – it penetrates the shell and seasons the meat from the outside in, which is why restaurant crab tastes better than crab steamed in plain water at home
• Do not overcook – rubbery, stringy crab meat is the number one sign of overcooking, and with pre-cooked frozen crab 10 minutes over boiling steam is really the maximum
• Kitchen shears beat a crab cracker every time for snow crab – cut along the length of the leg shell, peel it back, and the meat slides out in one whole piece
• Pour the garlic butter into individual ramekins so each person has their own – shared bowls cool fast and cold butter separates unpleasantly
• Save your shells – crab shells make an incredible seafood stock; simmer them with onion, celery, and bay leaves for 45 minutes and freeze the stock for bisques and risottos

Recipe Variations

• King crab upgrade – substitute king crab legs for a more dramatic presentation and richer flavor; increase steaming time to 12-15 minutes from thawed
• Cajun butter sauce – add 1 teaspoon Cajun seasoning, 1/4 teaspoon cayenne, and a dash of hot sauce to the garlic butter for a spicy version
• Lemon-herb butter – replace Old Bay in the sauce with 1 teaspoon fresh thyme, 1 teaspoon fresh tarragon, and extra lemon zest for a more delicate flavor profile
• Garlic-only butter – omit the Old Bay entirely for a simpler sauce that lets the natural sweetness of the crab shine through
• Broiled instead of steamed – brush thawed crab legs with butter, place cut-side up on a baking sheet, and broil 4 inches from the heat for 5-6 minutes until the meat is lightly golden

Common Mistakes to Avoid

• Overcooking the crab until the meat turns rubbery and stringy – pre-cooked frozen crab needs only 8-10 minutes from thawed; set a timer and pull it on time
• Steaming in plain water with no seasoning – the water is your only chance to flavor the meat directly, and plain water produces bland crab no matter how good the dipping sauce
• Serving cold or separated butter – butter that is not hot enough separates into greasy puddles; keep ramekins warm by sitting them in a small pan of hot water until serving
• Using salted butter for the sauce – salted butter combined with Old Bay makes the sauce aggressively salty; always use unsalted butter so you control the salt level
• No kitchen shears at the table – trying to crack snow crab with a regular cracker or a fork is frustrating and results in shell fragments in your food; good kitchen shears are the single most important tool for this dish

What to Serve With This Dish

• Cheddar Bay Biscuits – the ultimate Red Lobster pairing, and yes there is a copycat recipe for those too
• Corn on the cob – buttery sweet corn soaks up the garlic butter drippings and balances the savory crab perfectly
• Baked potato with sour cream and chives – a classic steakhouse-style side that makes the meal feel complete
• Simple green salad with a light vinaigrette – cuts through the richness of the butter and cleanses the palate between bites
• Chilled white wine or a crisp lager – a Pinot Grigio, Sauvignon Blanc, or light beer all complement the sweet briny crab without overpowering it

Frequently Asked Questions

What kind of crab legs does Red Lobster use?

Red Lobster primarily serves snow crab clusters – bundles of legs still attached at the body section. They also offer king crab legs as a premium option during certain promotions. Snow crab is the classic menu item and what most people picture when they think of Red Lobster crab.

Should I use frozen or fresh crab legs?

Frozen is actually ideal for this recipe. Nearly all crab legs – including what Red Lobster serves – are pre-cooked before freezing, so you are really just reheating them. Frozen crab legs are available year-round at a consistent price, while true fresh crab is seasonal and expensive. Thaw overnight in the fridge or cook directly from frozen with a few extra minutes of steaming time.

How do I thaw frozen crab legs?

The best method is to transfer them from the freezer to the refrigerator the night before and let them thaw slowly overnight – about 8-12 hours. If you are short on time, place them in a colander under cold running water for 20-30 minutes. Do not thaw in the microwave or in warm water; both cause uneven thawing and can partially cook the outer meat before the inside is ready.

How many calories are in Red Lobster crab legs?

A typical serving of snow crab legs at Red Lobster runs around 300-400 calories for the crab itself, but the garlic butter dipping sauce adds significant calories depending on how much you use. This copycat recipe comes in at about 380 calories per serving including a reasonable portion of the butter sauce. Snow crab meat on its own is very lean – about 90 calories per 3 ounces.

How much crab should I buy per person?

Plan on about 3/4 to 1 pound of crab legs per person if serving with sides. If crab is the star of the meal with minimal sides, go with 1 to 1.5 pounds per person. Keep in mind that snow crab legs are mostly shell – the actual meat yield is about 50-60% of the total weight, so a pound of legs gives you roughly half a pound of meat.

Can I bake crab legs instead of steaming?

Yes, the oven works great. Thaw the crab legs first, brush generously with melted butter, and arrange on a baking sheet. You can either bake wrapped tightly in foil at 400 degrees F for 15 minutes, or open-faced under the broiler for 5-6 minutes for lightly caramelized edges. The steaming method better replicates the Red Lobster experience, but baking is easier if you do not have a steamer setup.

What is the difference between snow crab and king crab?

Snow crab legs are thinner and longer with a slightly sweet, delicate flavor and tender texture. King crab legs are much larger and meatier with a bolder, more robust flavor. King crab is typically 3-4 times more expensive. For this Red Lobster copycat, snow crab is the authentic choice. King crab is a worthwhile upgrade for very special occasions – use the same recipe but add 3-5 minutes to the steaming time.

What can I substitute for garlic butter?

If someone at your table cannot have dairy, substitute equal parts high-quality vegan butter (Earth Balance or Miyoko’s work well) in the same recipe. For a completely different flavor profile, try a Cajun remoulade on the side – mix mayo, Dijon mustard, hot sauce, celery salt, and a squeeze of lemon. Plain drawn butter with just a pinch of salt also works beautifully if you want the crab flavor to stay front and center.

Are crab legs kid-friendly?

Kids usually love crab legs once you do the shell-cracking for them – the sweet mild flavor and fun interactive eating experience make it a hit with most children. I recommend cracking the legs open before serving to younger kids so they get the meat without the frustration of shells. Skip the Old Bay in the dipping butter for very young kids and just use plain melted butter with a little lemon – the flavor is gentler.

Why did my crab legs turn out rubbery?

Rubbery crab meat almost always means overcooked. Since the crab is already cooked before freezing, it only needs to be reheated – not cooked again from raw. Eight to ten minutes over boiling steam is enough from thawed crab legs. If you steamed them for 15-20 minutes thinking more time equals more doneness, that is the culprit. Pull them the moment they are hot all the way through and serve immediately.

Can I cook crab legs in an Instant Pot?

Absolutely – the Instant Pot is actually one of the fastest and most foolproof methods. Add 1 cup of water to the pot along with a squeeze of lemon and a teaspoon of Old Bay. Place the steam rack inside, arrange thawed crab legs on top (fold them to fit), and seal the lid. Cook on High Pressure for 2 minutes from thawed or 4 minutes from frozen. Quick-release the pressure immediately. The result is perfectly steamed crab in about 15 minutes total with minimal fuss.

Can I cook crab legs directly from frozen without thawing?

Yes, and it works very well with the steaming method. Simply add 4-5 extra minutes to the cooking time – steam frozen crab legs for 12-15 minutes instead of 8-10 minutes for thawed. The shells will still turn bright orange when done. This is my go-to method when I decide to make crab legs last-minute without time to thaw overnight. Just make sure your steaming water is at a full rolling boil before you add the frozen crab.
