How To Cook Crab Legs
There is nothing quite like sitting down to a big plate of perfectly cooked crab legs. Whether you are making a special dinner for someone you love or just treating yourself on a lazy weekend, crab legs are one of those meals that feel fancy but are actually pretty simple to pull off. I have been cooking crab legs at home for years, and once you learn the basics, you will never feel the need to order them at a restaurant again.
In this guide, I am going to walk you through every popular method for cooking crab legs. From boiling to steaming, from the oven to the air fryer, and even on a Blackstone griddle, you will find everything you need right here. By the time you finish reading, you will feel totally confident cooking crab legs no matter what tools you have in your kitchen.
How To Cook Crab Legs
Before jumping into the specific methods, let’s talk about the basics. Most crab legs you find at the grocery store have already been pre-cooked and then flash frozen. That means when you cook them at home, you are mostly just reheating them rather than cooking raw seafood from scratch. The main goal is to warm them all the way through without drying out that tender, sweet meat inside.
A few things to keep in mind before you start:
- Do not overcook them. Overcooked crab legs get rubbery and chewy, and that ruins the whole experience.
- Season generously. Crab has a beautiful natural sweetness, but the right seasoning takes it to another level entirely.
- Always serve with butter. Garlic butter, lemon butter, or plain melted butter. You just need it.

How To Cook Crab Legs in the Oven
The oven is a great hands-off option, especially when cooking for a group. It gives you more control, lets you season the crab legs really well, and the foil wrap keeps all the steam inside so the crab stays super juicy.
Ingredients
- 2 pounds of crab legs
- 4 tablespoons of melted butter
- 1 teaspoon of garlic powder
- 1 teaspoon of paprika
- Salt and pepper to taste
- Lemon wedges for serving
How To Make
- Preheat your oven to 375°F.
- Lay the crab legs out on a large baking sheet in a single layer.
- Mix together the melted butter, garlic powder, paprika, salt, and pepper in a small bowl.
- Brush the butter mixture generously all over the crab legs.
- Cover the baking sheet tightly with aluminum foil to trap the steam inside.
- Bake for 20 to 25 minutes until the crab legs are fully heated through.
- Remove the foil carefully, as hot steam will escape when you open it.
- Serve immediately with extra melted butter and fresh lemon on the side.
Pro tip: If you want a little extra color on the shell, remove the foil in the last 5 minutes and broil for a quick finish.
