• 1 tsp Old Bay seasoning
• 2 bay leaves

Lemon–Garlic Butter

• 8 tbsp (1 stick) unsalted butter
• 1 tbsp extra-virgin olive oil
• 6 garlic cloves, finely minced
• 1 lemon: 2 tsp finely grated zest + 3 tbsp juice
• 2 tbsp finely chopped fresh parsley, plus more for garnish
• 1/2 tsp kosher salt (adjust to taste)
• 1/4 tsp freshly ground black pepper
• 1/4 tsp red pepper flakes (optional)

Baby Potatoes

• 2 lb baby yellow potatoes
• Water to cover
• 1 tbsp kosher salt (for the boiling water)

To Serve

• 1 baguette or crusty loaf
• Lemon wedges (from the remaining lemon half)
• Flaky sea salt, to finish (optional)

Step-by-Step Instructions

Step 1: Prep the workspace and preheat

Preheat the oven to 375°F (190°C) for the bread. If your crab legs are frozen solid, quickly rinse them under cold running water for 3–4 minutes to loosen ice and speed up steaming. Rinse the potatoes and scrub if needed. Finely mince the garlic, zest and juice the lemon, and chop the parsley.

Step 2: Boil the baby potatoes

Place potatoes in a pot, cover with cold water by 1 inch, and add 1 tbsp kosher salt. Bring to a boil over high heat, then reduce to a steady simmer. Cook until a paring knife slips in easily, 12–15 minutes depending on size. Drain and return to the warm pot; cover to keep hot.

Step 3: Make the lemon–garlic butter

In a small saucepan over medium-low heat, melt the butter with the olive oil. Stir in the minced garlic and cook just until fragrant and barely golden, 1–2 minutes; do not brown. Remove from heat and stir in lemon zest, lemon juice, parsley, salt, pepper, and red pepper flakes (if using). Taste and adjust salt and lemon to your liking. Keep warm on the lowest heat or in a warm spot.

Step 4: Steam the crab legs

In a large pot fitted with a steamer basket, combine 2 cups water, 1 cup white wine (or water), the Old Bay, bay leaves, and half a lemon. Bring to a boil, then add the crab legs, cover tightly, and steam until heated through: 6–8 minutes from frozen, or 4–5 minutes if thawed. The meat should be hot and opaque, with shells very fragrant; target 145°F (63°C) internal for reheating.

Step 5: Crack and toss in butter

Transfer crab legs to a large bowl or rimmed platter. Use kitchen shears to cut along the shell’s thinner side; crack at the joints and remove cartilage. Drizzle and toss the hot crab with about two-thirds of the lemon–garlic butter so it clings to the meat. Scatter with a little extra parsley and black pepper.

Step 6: Finish potatoes and warm the bread

Toss the hot potatoes with 2 tbsp of the lemon–garlic butter (or plain butter) until lightly glossy. Taste and add a pinch of salt if needed. Warm the baguette in the oven for 6–8 minutes until crisp on the outside and soft inside. Slice or tear into chunks.

Step 7: Plate and serve

Arrange the crab legs on a warm platter with the potatoes alongside. Serve with the remaining lemon–garlic butter for dipping, lemon wedges, and flaky sea salt. Don’t forget crab crackers or kitchen shears and small picks for easy eating.

Pro Tips

• Use kitchen shears to cut along the thinner side of the shell—it’s faster and cleaner than cracking alone.
• Add a tablespoon of olive oil to the butter to keep it silky and prevent separation as it sits.
• Keep butter warm in a small insulated mug or thermos so it stays pourable at the table.
• Steam in batches if needed; overcrowding drops the pot temperature and can make the crab watery.
• Save shells to make seafood stock. Freeze them in a zip-top bag for up to 3 months.

Variations

• Cajun Garlic Butter: Swap Old Bay for 1 tsp Cajun seasoning and add a pinch of cayenne. Finish with chopped chives.
• Brown-Butter Lemon: Brown the butter until nutty before adding garlic; reduce lemon juice to 2 tbsp to keep balance.
• Roasted Sheet-Pan Method: Skip steaming. Place crab on a foil-lined sheet, spoon over half the butter, cover with foil, and roast at 425°F (220°C) for 8–10 minutes. Toss with remaining butter.

Storage & Make-Ahead

Crab is best right away. If you have leftovers, remove meat from shells and refrigerate in an airtight container up to 2 days. Reheat gently in a covered skillet with a splash of water or butter for 1–2 minutes—just until warm. Potatoes can be boiled up to 2 days ahead; reheat in the microwave or sauté with a dab of butter. Lemon–garlic butter can be made 3 days ahead (refrigerated) or 1 month ahead (frozen); rewarm gently until fluid. Bread is best same day; freeze leftovers and re-crisp in a hot oven.
