Ingredients

6 king crab legs
1/3 cup melted butter, for serving

Instructions

Thaw – Make sure the crab legs are fully thawed. If using frozen crab legs, simply add a few extra minutes to the cooking time.
Preheat – Set your oven to 350°F (175°C). Line a large baking sheet or jelly roll pan with aluminum foil or parchment paper.
Bake – Arrange up to 4 crab legs on the prepared pan. If you need to use two pans, the cooking time may be slightly longer. Bake for 25–35 minutes, depending on the size of the legs. Check after 25 minutes—they should be heated through and releasing a little steam.
Serve – Cut open the shells with kitchen shears or use crab crackers to remove the meat. Serve immediately with melted butter for dipping.
Store leftovers – Keep any leftover crab meat in an airtight container in the refrigerator for up to 3 days. Leftovers are perfect for crab cakes, salads, or crab dip.

Tips

Thaw crab legs overnight in the refrigerator for the best texture and flavor.
For quicker thawing, place the legs in a sealed plastic bag and submerge in cold water for 20–30 minutes.
Always bake crab legs in their shells to retain moisture and prevent them from drying out.
Use sharp kitchen shears to cut through the shells more easily.

Variations and Substitutions

Seasoned butter: Mix garlic, lemon juice, or fresh herbs into the melted butter for extra flavor.
Grilled crab legs: Instead of baking, grill the crab legs over medium heat for 5–7 minutes per side.
Steamed crab legs: Place legs in a steamer basket over boiling water for 6–8 minutes until heated through.
Dairy-free option: Swap butter for olive oil or a plant-based butter substitute.

FAQs

Do I need to cook king crab legs from raw?
Most king crab legs sold in stores are pre-cooked and frozen, so you’re reheating them rather than cooking them from raw.

How do I know when they’re done?
They should be hot all the way through and slightly steamy. The meat will be opaque and firm.

Can I freeze leftovers?
Yes. Cooked crab meat can be frozen for up to 2 months. Store it in an airtight container or freezer bag.
