Baked Crab Legs in Butter Sauce
The crowning glory of this indulgent dish is the crab itself—succulent legs drenched in a golden pool of buttery brilliance. A harmony of bright lemon, pungent garlic, and sea-sweet meat delivers a taste that is at once decadent and comforting. Every mouthful echoes the ocean’s bounty, wrapped in velvety, aromatic richness.

Choosing the Best Ingredients
The secret to perfect baked crab lies in meticulous ingredient selection. These are the pillars of flavor:
Crab Legs – Alaskan King or Snow Crab are best. Choose legs that are firm and emit a clean, briny scent. Pre-cooked and frozen options save time and taste pristine when thawed properly.
Butter – Opt for premium unsalted butter. It offers a blank canvas for seasoning and layers beautifully with aromatics.
Garlic – Fresh, tight cloves bursting with fragrance work best. Avoid any that show green sprouts.
Lemon – Select lemons with taut, glossy skin. Their juice and zest brighten the dish and balance the richness.
Ingredients
- 2 lbs Alaskan King Crab or Snow Crab legs, thawed
- 1 cup (2 sticks) unsalted butter
- 6 cloves garlic, minced
- 1 tbsp fresh lemon juice
- 1 tsp lemon zest
- Salt and pepper, to taste
- Chopped fresh parsley, for garnish
- Lemon wedges, for serving

Instructions
Step 1: Prep and Assemble
Gather all components. Mince the garlic and zest the lemon—two simple steps that will flood your kitchen with citrusy, savory anticipation.
Step 2: Crafting the Butter Sauce
In a medium pan over gentle heat, melt the butter slowly until fluid but not browned. Stir in the garlic and let it sizzle for 1–2 minutes—just until fragrant. Add the lemon juice, zest, salt, and black pepper. Stir well and remove from heat.
Step 3: Arrange the Crab
Preheat oven to 375°F (190°C). Nestle the thawed crab legs in a spacious baking dish. Pour half the butter sauce over them, coating each leg generously.
Step 4: Bake to Perfection
Cover tightly with foil and bake for 15–20 minutes, allowing the buttery infusion to penetrate deep into the meat.
Step 5: Broil and Finish
Remove foil. Drizzle the remaining sauce on top and slide the dish under the broiler for 2–3 minutes. The tops will develop a golden gloss. Finish with a sprinkle of parsley and serve alongside lemon wedges for a zesty flourish.

The Best Variations of the Dish
Spicy Kick
Add chopped jalapeños or hot sauce into the butter for a fiery surprise that contrasts beautifully with the sweet crab.
Herb-Infused Elegance
Infuse the butter with rosemary or thyme. Sauté herbs with the garlic to extract deep, earthy tones.
Citrus Medley
Incorporate lime or orange juice along with the lemon for a more exotic, tangy profile.
Lightened-Up Twist
Replace half the butter with extra virgin olive oil. It still delivers richness with a healthier edge.
