What is Soft Shell Crab Tempura?

Soft shell crab tempura is a simple dish consisting of soft shell crab that is dipped into a tempura batter and fried in oil. I drizzle it with a little lemon juice and serve either on a sandwich or by itself with some dynamite sauce. You can also enjoy it in a sushi roll, such as the spider roll.

Soft shell crabs are actually blue crabs that have recently molted, or shed their thicker outer shell. The entire crab is edible once cleaned (remove the face, gills, and flap underneath the crab). It does have a stronger seafood flavor than other types of crab, which I enjoy.

How do you Make Soft Shell Crab Tempura?

Like most tempura cooking, preparing the tempura batter and heating the oil takes most of the time. Otherwise, making soft shell crab tempura goes very quick. Below are step-by-step instructions:

Prepare the Crab and Heat the Oil

1. Before beginning, make sure you thaw your crab if frozen. The best way to do this is in the fridge overnight. However, if you are short on time, you can place in a plastic bag and soak in cold water until thawed.

2. When you are ready to begin, heat vegetable oil in a sauce pan on medium heat to 350 degrees.

Heat oil on medium heat to 350 degrees.

3. Next, make sure your soft shell crabs are cleaned. Most often they will come cleaned if you purchase from a seafood vendor. If not, you can clean by cutting the face off, removing the gills from under both sides of the crab, and removing the flap from the underside of the crab.

4. Blot your soft shell crabs with a paper towel to dry them off. If they are too wet they will pop during frying.

Blot the soft shell crab dry with a paper towel.

Prepare the Tempura Batter

1. To prepare the tempura batter you will first need to assemble the ingredients and chill the water. You may need to add ice if you don’t have access to very cold water. However, make sure to remove ice cubes before combining with egg.

2. Next, crack the egg into a small mixing bowl and beat until the yolk and white are combined.

To make the tempura batter, start by cracking an egg into a mixing bowl.

3. Once the egg is combined, add cold water to the egg and mix well. I use ice water to assure the water is cold enough. I then strain the ice cubes when adding the water to the egg.

Add cold water to the egg, making sure the ice does not get into the tempura batter.

4. Once the egg and water are mixed, sift one cup of flour into the egg and water combination.

Sift flour into the mixing bowl.

5. Using a spoon or chopstick, lightly mix the batter making sure not to over stir. The batter should be mixed but a little lumpy.

Mix tempura batter until everything is combined but the batter is a little lumpy.

Cook the Soft Shell Crab Tempura

1. Once the tempura batter is prepared, place one cup of flour into a bowl or onto a plate. Then dip the crabs into the flour making sure to cover both sides of the crab along with the legs.

Dredge the soft shell crab in flour prior to frying the soft shell crab tempura.

2. Dip the flour coated crabs into the tempura batter ensuring the entire crab is coated with batter. Then place the tempura coated crab into the hot oil and cook for 4 minutes.

Dip soft shell crab in tempura batter and add to the hot oil.

3. After four minutes, remove from the oil and place the crabs onto a paper towel-lined plate.

After cooking for around four minutes, remove the soft shell crab tempura and place on a paper towel-lined plate.

4. Serve and enjoy!
