The Stars of the Show: Key Ingredients
The beauty of this recipe lies in its simplicity. You only need a few high-quality ingredients to let the sweet flavor of the crab shine through.
Choosing Your Crab: King vs. Snow
You can use either King Crab or Snow Crab for this recipe. King Crab legs are larger, with thicker shells and huge, meaty portions. Snow Crab legs are smaller and sweeter, with thinner shells that are easier to crack. Both are typically sold pre-cooked and frozen, so your main job is to heat them through and infuse them with flavor.
For the Perfect Garlic Butter Sauce
- Crab Legs: About 2 pounds of King or Snow crab legs.
- Butter: Use a high-quality salted butter for the best flavor.
- Garlic: Freshly minced garlic is a must. Avoid the pre-minced jarred kind for this recipe.
- Lemon Juice: Freshly squeezed lemon juice brightens up the rich butter sauce.
- Parsley: Freshly chopped parsley adds a touch of color and freshness.
- Old Bay Seasoning: A classic seafood seasoning that adds a savory, slightly spicy kick.

How to Make Garlic Butter Crab Legs: A Step-by-Step Guide
Making delicious Garlic Butter Crab Legs is easier than you think. Just follow these simple steps for a perfect result every time.
Step 1: Prepare the Garlic Butter Sauce
In a small saucepan, melt the butter over medium heat. Add the minced garlic and cook for about 1-2 minutes until fragrant, being careful not to burn it. Remove from heat and stir in the lemon juice, chopped parsley, and Old Bay seasoning. Set your delicious sauce aside.
Step 2: Choose Your Cooking Method
Since most crab legs are already cooked, you’re simply reheating them. Here are our top three methods.
Method 1: Baking (Our Favorite!)
Baking is our preferred method as it infuses the crab with flavor without adding extra water.
- Preheat your oven to 400°F (200°C).
- Arrange the crab legs in a single layer on a large baking sheet.
- Brush the crab legs generously with about half of the garlic butter sauce.
- Bake for 10-12 minutes, or until heated through and fragrant.
- Serve immediately with the remaining garlic butter sauce for dipping.
Method 2: Steaming
Steaming is a classic method that gently heats the crab, keeping the meat tender and moist.
- Add about an inch of water to a large pot with a steamer basket and bring to a boil.
- Place the crab legs in the steamer basket over the boiling water.
- Cover the pot and steam for 5-7 minutes, until the crab is heated through.
- Remove the crab legs and serve with the garlic butter sauce on the side.
Method 3: Boiling
Boiling is the quickest method, but be careful not to overcook the crab as it can become watery.
- Bring a large pot of salted water to a rolling boil.
- Carefully add the crab legs to the pot.
- Boil for 3-5 minutes, just until heated through.
- Drain the crab legs well and serve with the garlic butter sauce.
Tips for Restaurant-Quality Crab Legs at Home
- Don’t Overcook: Remember, the crab legs are already cooked. You are just reheating them. Overcooking will make the meat tough and rubbery.
- Thaw First: For 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.
- Serve Immediately: Crab legs are best enjoyed hot, right after cooking. Have your side dishes ready to go. For more ideas on quick meals, check out these quick chicken dinner ideas.
What to Serve with Your Garlic Butter Crab Legs
Complete your seafood feast with some classic sides. We love serving our crab legs with steamed potatoes, corn on the cob, and crusty bread like our garlic butter dinner rolls to sop up all that delicious garlic butter. A simple green salad with a light vinaigrette also makes a refreshing accompaniment. And for dessert, why not try some easy lemon cookie bars?
Storing and Reheating Leftovers
If you have any leftovers, store them 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 bake at 350°F (175°C) for 5-7 minutes, until just heated through.
