Ingredients You’ll Need
- 2 lbs crab legs (king or snow crab) – thawed if frozen
- 1/2 cup (1 stick) unsalted butter
- 5–6 cloves garlic, minced
- 1 tablespoon lemon juice (freshly squeezed)
- 1 teaspoon Old Bay seasoning (optional, for that classic seafood flair)
- 1 tablespoon chopped parsley (optional, for garnish)
- Salt, to taste
- Lemon wedges, for serving
🦀 Pro Tip: Use pre-cooked crab legs (as most sold in stores are). You’ll only need to reheat them—no boiling required!
Kitchen Equipment You’ll Need
- Large skillet or saucepan (with lid)
- Kitchen shears (for cracking or trimming shells)
- Tongs
- Garlic press or chef’s knife
- Serving platter
- Small dipping bowls (for extra butter, optional)
Step-by-Step Instructions
Step 1: Prep the Crab Legs
If the crab legs are frozen, let them thaw completely in the refrigerator or under cold running water. Once thawed, use kitchen shears to gently cut the shell open along one side for easier access to the meat. Pat the crab legs dry with a paper towel.
Step 2: Make the Garlic Butter
In a large skillet or saucepan over medium heat, melt the butter. Add the minced garlic and sauté for 1–2 minutes, just until it’s fragrant and softened—be careful not to let it brown.
Stir in the lemon juice and Old Bay seasoning (if using). Let it simmer for another minute to meld the flavors.
Step 3: Add the Crab Legs
Place the prepared crab legs into the skillet, arranging them so they’re as evenly spread out as possible. Spoon the garlic butter over them generously, ensuring every piece is well-coated.
Cover with a lid and cook for 4–6 minutes, turning once or twice to ensure even heating and butter coverage.
Step 4: Serve and Garnish
Transfer the warm crab legs to a serving platter. Pour any remaining garlic butter over the top and garnish with chopped parsley and lemon wedges. Serve immediately with extra melted butter on the side for dipping, if desired.
Tips for Success
- Don’t overcook: Crab legs are usually pre-cooked. You’re simply warming them through—too long in the skillet can make them rubbery.
- Keep the shells cracked: Slightly opening the shells before cooking makes eating less messy and more enjoyable.
- Use clarified butter for a more refined flavor and texture—especially if serving guests.
- Double the garlic if you’re a garlic lover. No shame here!
Flavor Variations
- Spicy Cajun Crab Legs: Add a teaspoon of Cajun seasoning or chili flakes to the butter mixture.
- Herb-Infused Butter: Add fresh thyme, rosemary, or tarragon to the butter sauce for a fragrant twist.
- White Wine Touch: Add 2 tablespoons of white wine when cooking the garlic for a richer depth of flavor.
- Zesty Citrus: Add a little orange zest to the lemon juice for a unique, sweet-savory finish.
What to Serve With Garlic Butter Crab Legs
Balance the richness of the butter and sweetness of the crab with simple, flavorful sides. Here are some perfect pairings:
- Steamed or roasted asparagus
- Garlic butter rice or lemon couscous
- Crisp Caesar salad
- Buttery corn on the cob
- Crusty bread or garlic toast (perfect for mopping up leftover butter)
Beverage Pairings:
- Dry white wines such as Sauvignon Blanc, Pinot Grigio, or Chardonnay
- Light beers like pilsners or wheat ales
- Sparkling water with lemon for a refreshing non-alcoholic option
How to Store Leftovers
While crab legs are best enjoyed fresh, leftovers can be saved:
- Refrigeration: Store in an airtight container in the fridge for up to 2 days.
- Reheating: Gently reheat in a covered skillet with a splash of water or extra butter to keep the meat moist.
- Freezing: Not recommended once cooked and reheated, as texture may suffer.
FAQs About Garlic Butter Crab Legs
Can I make this recipe ahead of time?
It’s best served fresh, but you can prep the garlic butter and crack the shells in advance. Then just reheat everything before serving.
What’s the best way to thaw frozen crab legs?
Place them in the fridge overnight or run them under cold water for 10–15 minutes. Never thaw in hot water.
Do I need to boil the crab legs first?
Nope! Most crab legs are pre-cooked when sold frozen. This recipe is just for reheating and flavoring, not cooking from raw.
Can I use imitation crab?
This recipe is designed for real crab legs. Imitation crab can be used in a pinch, but it won’t have the same flavor or texture.
What’s the best crab to use—king or snow?
King crab offers larger, meatier legs and a rich flavor. Snow crab is slightly sweeter and easier to handle. Both work beautifully!
