Choosing the Best Crab Legs: King vs. Snow Crab
The star of the show is the crab, so choosing well is key. You’ll most often find crab legs pre-cooked and frozen at the grocery store. The two most popular varieties are King Crab and Snow Crab, and both work beautifully for this recipe.
King Crab Legs are the larger, more impressive option. They have a thick, spiky shell that protects a huge, meaty portion of rich, sweet crab. They are a premium choice and perfect for a big celebration. Snow Crab Legs are smaller and have a thinner, smoother shell that’s easier to crack. The meat is sweet with a subtle briny flavor. They are generally more affordable and a fantastic choice for any occasion.

How to Make Garlic Butter Crab Legs (Two Ways!)
Whether you’re a fan of the classic steamed method or the deeper flavor of baking, we have you covered. Both methods are incredibly simple and yield delicious results. The key is to remember that the crab legs are already cooked; you are simply reheating them and infusing them with flavor.
Method 1: Steaming (The Classic Approach)
Steaming is a quick and gentle way to heat the crab legs, ensuring the meat stays tender and moist. It’s our go-to method for classic Garlic Butter Crab Legs.
- Prepare the Pot: Fill a large pot with about an inch of water. Add a generous pinch of salt and bring it to a boil. If you have a steamer basket, place it inside.
- Steam the Crab: Carefully arrange the crab legs in the steamer basket or directly in the pot. Cover and steam for 5-7 minutes, or until the crab is heated through and fragrant.
- Make the Sauce: While the crab is steaming, melt the butter in a small saucepan over medium heat. Add the minced garlic and cook for 1-2 minutes until fragrant, being careful not to let it brown. Remove from heat and stir in the lemon juice, chopped parsley, Old Bay Seasoning, and red pepper flakes.
- Serve Immediately: Arrange the hot crab legs on a platter and serve with the warm garlic butter sauce in a small bowl for dipping.

Method 2: Baking (For a Deeper Flavor)
Baking, or roasting, the crab legs allows the garlic butter to meld directly with the crab meat, creating a slightly deeper, more roasted flavor profile.
- Preheat Oven: Preheat your oven to 400°F (200°C).
- Prepare the Sauce: Melt the butter in a small saucepan over medium heat. Add the minced garlic and cook for 1-2 minutes until fragrant. Stir in the lemon juice, parsley, Old Bay, and red pepper flakes.
- Coat the Crab: Arrange the crab legs in a single layer on a large baking sheet. You can use a pastry brush to coat them generously with the garlic butter sauce, or simply pour it all over.
- Bake: Bake for 10-12 minutes, or until the crab is heated through and the sauce is bubbling.
- Serve: Serve immediately, drizzling any extra sauce from the pan over the crab legs.
Pro Tips for Restaurant-Quality Results
Follow these simple tips to elevate your crab leg feast from great to absolutely spectacular.
- Thaw Properly: For the best results, thaw your frozen crab legs in the refrigerator overnight. If you’re short on time, you can thaw them under cold running water for about 20-30 minutes.
- Don’t Overcook: Remember, the crab is already cooked! You are just reheating it. Overcooking will lead to tough, rubbery meat.
- Use Fresh Ingredients: Fresh garlic, lemon juice, and parsley will always provide a superior flavor compared to their bottled or dried counterparts.
- Provide Tools: Serve with crab crackers and small forks to make it easy for everyone to enjoy every last morsel of meat.
What to Serve with Your Crab Feast
Turn your Garlic Butter Crab Legs into a full-blown feast with some classic pairings. A simple green salad or roasted vegetables like our Easy Parmesan Brussels Sprouts are great options. For something more substantial, consider serving them alongside a creamy pasta, baked potatoes, or crusty bread for dipping in that incredible sauce. And for a truly satisfying meal, these crab legs are the perfect centerpiece for a weeknight creamy mac and cheese.
Storing and Reheating Leftovers
While Garlic Butter Crab Legs are best enjoyed fresh, you can store leftovers in an airtight container in the refrigerator for up to 2 days. To reheat, we recommend the oven method. Place the crab legs on a baking sheet, brush with a little melted butter, and warm in a 350°F (175°C) oven for about 5-7 minutes, or until heated through. Avoid the microwave, as it can make the crab meat rubbery.
Frequently Asked Questions about Garlic Butter Crab Legs
You can, but we recommend unsalted butter. Different brands of salted butter contain varying amounts of salt. Using unsalted butter allows you to control the seasoning, especially since you’ll also be adding Old Bay Seasoning, which contains salt.
Since the crab legs are already cooked, your only goal is to heat them through. This usually takes 5-7 minutes for steaming or 10-12 minutes for baking. You’ll know they’re ready when they are hot to the touch and smell fragrant.
Yes, for the best and most even results, we highly recommend thawing the crab legs before you begin. The ideal way is to let them thaw overnight in the refrigerator. If you’re in a rush, you can run them under cold water for 20-30 minutes.
The best way is to use a seafood cracker tool. If you don’t have one, you can use a nutcracker or the back of a heavy spoon to gently crack the shell. For snow crab, you can often snap the legs at the joints and use kitchen shears to cut down the shell.
Both King Crab and Snow Crab legs work wonderfully. King crab legs are larger and meatier, while snow crab legs are sweeter and easier to handle. Since they are pre-cooked and frozen, choose whichever you prefer or have available.
