Making fried crab legs in the air fryer is so easy! This recipe uses snow crab and claws drizzled in butter, garlic, and lemon for epic flavor.

Why Use an Air Fryer?
The most obvious reason is time savings. Air frying always cuts down on cook time in comparison to baking. My Baked Crab Legs recipe takes 25 minutes to bake. These are done in less than 10 minutes.
Another great reason is FLAVOR. Because these are cooked so closely to the circulating fan in the air fryer, they lock in a lot more of the garlic butter flavor than you will get if you bake these. The flavor penetrates well into the shell when air frying.
A huge con is that you cannot cook large batches unless maybe you use an air fryer oven. Other than that, these are perfect for making a few clusters at a time.
What Type of Crab Legs to Use: The Difference Between Snow Crab and King Crab Legs
I’m using snow crab in this recipe. Snow crab legs are sold in clusters and typically by the pound. They are much easier to handle and crack, in comparison to king crab legs, because they have a smooth shell. There are usually at least 4 legs in each cluster. Their flavor is mild and sweet.
King crab legs have a very prickly shell. They are large in size and are typically sold individually (by the leg) in pounds. The meat is a little more delicate and sweeter. They are a lot more expensive than snow crab. (I usually get these for New Year’s!).
King crab legs likely won’t fit in the air fryer unless you use a large air fryer oven. You can try cutting them to fit.
How to Buy and Shop
Most crab will come precooked and often frozen. Sometimes, if it’s sold thawed, then it has been thawed from frozen. After the crabs are caught they are cooked on the boat and then flash-frozen right on the spot. If the crab legs are orange or red in color when you bought them, then they have already been cooked. This process is reheating them.
How to Thaw
The best way to thaw is to put them in the refrigerator overnight (at least 8 hours). You can also put them in a bowl and run cool water over them to thaw quickly.
Thawed crab will last in the fridge for 1-2 days.
What Type of Seasoning to Use
I like to use Cajun Seasoning (optional) and Old Bay along with melted butter, olive oil, parsley, and fresh lemon.
How to Make Air Fryer Crab Legs
Detailed measurements and full instructions can be found in the recipe card at the bottom of this post.
- Combine the ingredients for the garlic butter sauce in a bowl.
- Brush the mixture over both sides of the crab legs.
- Wrap the crab legs in foil and air fry.
Air Fryer Temperature
I use 370 degrees.
Cook Time/How Long to Cook
Cook time is 5-8 minutes.
Frozen Crab Legs
You can cook frozen crab legs by adding 2-3 minutes of additional cook time. I typically thaw them because in my experience, using frozen, creates excess water within the crab.
How to Reheat
I don’t reheat them. I love to serve these with warm butter and that provides the temperature adjustment I need. If you know you want to eat more of them later, crack them first. The longer they sit, the harder they are to crack and the meat gets trapped inside.
If you must reheat, saute the crab meat in a pan with oil or butter until warm.

Notes
- You cannot cook large batches unless maybe you use an air fryer oven. Other than that, these are perfect for making a few clusters at a time.
- Depending on the air fryer you use, you may need to flip the crab legs halfway through the cooking time to ensure the clusters are cooked through.
- Every air fryer cooks at varying speeds. Keep a watchful eye for accurate cook time.
- You will likely have trouble getting king crab legs to fit. You may be able to cut them. I have not tested king crab legs in the air fryer.
- Adjust the spices and seasoning to suit your taste. Omit the Cajun seasoning if you want.
- If your crab legs don’t have much flavor, you didn’t purchase quality crab or the crab is expired/has gone bad. Even without seasoning, the crab legs should have a sweet taste (if they haven’t gone bad).
- Some people feel like brushing the garlic butter sauce and seasoning onto the crab legs makes it more of a messy experience. It does. Feel free to skip this step and use the ingredients as a dipping sauce.
- I typically make an extra batch of the garlic butter sauce just for dipping because I love to dip.
- To crack a crab leg, I hold the leg horizontally, with the back of the leg facing me. Then press down on either the middle of the leg or about 1/4 of the way up from the bottom of the leg. I can always tell if the crab is fully cooked (reheated) and fresh because of how easily it cracks.
- If when I crack the leg, it doesn’t return a nice chunk of meat, and the meat is stuck on the inside, it’s usually because it wasn’t cracked soon enough after cooking. The longer they sit, the harder they are to crack and easily remove the meat.
- I tested these in the Instant Pot and in the oven. Making them in the Instant Pot is probably my favorite. The shells are the easiest crack likely due to the pressure cooking.

ABSOLUTELY DELICIOUS! I've made this twice now due to a sale in frozen crab legs near me and we just can't get enough! The recipe was extremely easy and clear to follow.

Never thought about putting these in the air fryer as I always use the oven. These came out great and clean up was easy!
