What Is King Crab?

King crabs are a large species of crab harvested from the waters surrounding Alaska and the Aleutian Islands. Because of its great size and the limited fishing season, king crab is more expensive than other types of crabs. It also has a milder taste that's often compared to lobster. King crab is a delicacy and makes an enticing seafood special, especially during the summer months.

Watch our video to learn three different way to prepare king crab legs:

Cooking King Crab

King crab is cooked and frozen immediately after harvesting. This preserves the crab meat and makes it safe to ship king crabs all over the world. That's why you don’t need to operate in a coastal town to add Alaskan king crab legs to the menu! Unlike picking a blue hard-shell crab, eating king crab is much less work which makes it an appealing seafood option for customers.

The night before you plan to prepare the king crab, place the frozen crab legs in your walk-in cooler to thaw. This is the easiest way to thaw the crab meat before cooking. Rinse the thawed crab legs with water to remove any sand, and now you're ready to cook! Check out these three popular cooking methods:

1. Steaming

Steaming King Crab Legs

Steaming is a quick, easy way to prepare king crab. To get started, you'll need a large stock pot and a steamer basket. Try a steamer kit if you're cooking outdoors or hosting a seafood boil.

How to Steam King Crab Legs

  1. Fill pot with water until just below steamer basket or steaming grate.
  2. Heat water to a boil (on range top or outdoor burner).
  3. Add desired seasonings to water.
  4. Carefully place thawed crab legs into steamer basket and reduce heat.
  5. Allow to simmer for 5 to 7 minutes.
  6. Remove crab legs with high-heat tongs and rinse before plating.
  7. Serve with melted butter and lemon wedges.

How Long to Steam King Crab Legs?

King crab legs cook quickly, so you only need to steam them for roughly 5-7 minutes if they are already thawed.

2. Grilling

Grilling King Crab Legs

If you haven't tried grilling fish and seafood yet, it's a great way to get more versatility out of your outdoor grilling equipment. Freshly grilled king crab legs make an enticing summer special. The grill marks provide visual appeal, and you won't need to clean the steamer pot afterward. All you need is an outdoor grill and a pair of high-heat tongs.

How to Grill King Crab Legs

  1. Brush thawed crab legs with olive oil.
  2. Heat grill or charbroiler to 300 degrees Fahrenheit.
  3. Place king crab legs directly onto grill grate.
  4. Cook for 5-7 minutes, then flip the legs and cook an additional 5-7 minutes.
  5. Serve with melted butter and lemon wedges.

How Long to Grill King Crab Legs?

King crab legs only take about 10 to 15 minutes to cook on the grill. Just make sure the grill isn't too hot or the crab legs will dry out.

  2. Place thawed crab legs in single layer in shallow baking pan.
  3. Add a small amount of water to the pan so that it covers the bottom (about 1/8" to 1/4" deep).
  4. Brush crab legs with butter, seasoning, and/or lemon juice.
  5. Cover the pan with aluminum foil and bake for 8 to 10 minutes.
  6. Serve with melted butter and lemon wedges.

King Crab FAQ

What Is King Crab?

Still have questions about cooking king crab legs? We answer some common queries below.

Is King Crab Sustainable?

Yes, king crab can be considered a sustainable seafood option depending on where it's harvested. According to Seafood Watch, king crab species that are wild-caught in Alaska are harvested in a way that causes little harm to habitats and wildlife. They recommend avoiding king crab harvested in Russia. In the US, the king crab fishing season and quotas are strictly regulated to avoid overfishing.

Is it Better to Steam or Boil King Crab?

Steaming is a gentler method of cooking than boiling. When you boil crab legs, you risk overcooking the meat which makes it rubbery. Submerging the crab legs in water when you boil also leads to water-logging of the meat. We recommend steaming for better results.

Should I Thaw King Crab Before Cooking?

While you can cook frozen king crab legs, we recommend thawing the crab overnight first. This will give you the best results because the crab legs will cook evenly and quickly.

Do You Rinse King Crab Legs Before Cooking?

It's a good practice to give your thawed king crab legs a quick rinse just in case there's any sand or dirt present on the shells.

Can You Overcook King Crab?

Yes, you can overcook king crab. Because it's already cooked and just needs to be reheated, overcooking is a common mistake. This will make the crab tough, rubbery, and not as flavorful.

Even though it's a pricey meal, king crab is easy to prepare. A simple reheat in a steamer basket is all it takes to produce delicious, flakey crab meat. If you're considering adding seafood to your menu, try Alaskan king crab for a profit-boosting nightly special.

Serving - 2 or 3 Back to Top Shrimp Types While there are over 300 different edible species of shrimp in the world, you’ll only find a handful of different types being used in recipes. Still, these different types of shrimp can vary greatly, as some have mild flavors and delicate textures while others have bold and briny flavors. Not only do these types pair differently with other foods, but they are also cooked and prepared differently as well. We’ll cover some of the most important types of shrimp, allowing you to elevate your seafood dishes to the next level. Rock Shrimp Rock shrimp are named for their rock-hard shells, although they are typically deshelled before being sold. This type of shrimp tends to be smaller, usually only a few inches in length. Rock shrimp’s flavor profile is similar to that of lobster, and it is often used in seafood dishes as a less expensive alternative to lobster meat. For this reason, rock shrimp can be used in a slew of different recipes, but are most commonly fried for dishes such as tempura or popcorn shrimp. Tiger Shrimp When cooked, this type of shrimp has a striped pattern on its back, giving tiger shrimp its name. Tiger shrimp is one of the larger types of shrimp, providing a lot of meat for use. This type of shrimp has a mild taste, meaning it's best paired with foods or toppings with strong flavors. As a result, you’ll find tiger shrimp used in recipes like shrimp cocktails, or in mixed seafood dishes like scampi or paellas. White Shrimp White shrimp are small warm-water shrimp native to the East Coast of the United States, turning from a translucent color to white when cooked. Warm-water varieties like white shrimp are known for their ability to absorb flavors from sauces and seasonings. As a result, this type of shrimp is great in tandem with barbeque and curry sauces. You’ll find white shrimp being used in dishes like gumbo and shrimp creole as well. Pink Shrimp Pink shrimp get their name from their pinkish color when raw. This type of shrimp is similar to white shrimp, and the two are sometimes used interchangeably. However, pink shrimp are often larger and sweeter than other warm-water shrimps. Due to their large size and sweet taste, pink shrimp is one of the best options to include in a seafood boil. Royal Red Shrimp Royal red shrimp are among the most sought-after type of shrimp, as they are known for their tenderness and delicious, salty flavor. These shrimp are extremely popular, often being compared to bay scallops in terms of taste. Royal red's strong and buttery flavor lends itself perfectly to a variety of recipes, but they can commonly be found in risotto and shrimp and grits. Alternatively, royal red shrimp can be served as its own main course with a side of melted butter, highlighting the food's delicious flavor and tender texture. Back to Top Different types and sizes of shrimp have different flavor profiles and uses, making it key for restaurant operators to understand the difference. Knowing the different types and sizes of shrimp makes it easier to include the food in recipes, greatly enhancing a dish. Failure to understand the different types of shrimp can lead to unbalanced portions and unpleasant flavor profiles. Any restaurant operator planning to use shrimp and other seafood in their menu should be well aware of the different types and sizes and how each should be used.

Discard the top shell. In one swooping motion, run your knife along the bottom part of the bottom shell under the oyster's meat to detach it, then flip the oyster’s meat so the smooth part of the meat comes up to the top.
