Tempura is a Japanese method of lightly battering and deep-frying foods, most often seafood or vegetables.

The cooking time for air-fried tempura prawns varies depending on the desired level of crispness, the size of the prawns, and the power of the air fryer. On average, it takes around 8-12 minutes to cook tempura prawns in an air fryer at 200°C/400°F.

Air fryer temperature and timing

The temperature and timing for cooking tempura prawns in an air fryer depend on whether the prawns are fresh or frozen, and whether you want to cook them through or just reheat them.

Cooking Fresh Tempura Prawns

Fresh tempura prawns should be cooked at a temperature between 350–400°F (160–200°C) for 6–8 minutes. If you are using tiger prawns or larger prawns, adjust the cooking time accordingly.

Cooking Frozen Tempura Prawns

Frozen tempura prawns can be cooked straight from frozen. There is no need to defrost them first. Set the air fryer temperature to 400°F (200°C) and cook for 8–15 minutes. If you are cooking a small batch of prawns, they may only need 4 minutes per side. Check if they are golden brown after 4 minutes, and if so, they are done. If not, add an extra 1–2 minutes.

Batter ingredients and preparation

Tempura batter is typically made with three main ingredients: flour, starch, and carbonated water. However, you can add other ingredients to improve the flavour or texture. For example, you can use cake flour instead of plain flour, and potato starch or cornstarch for a lighter texture. You can also add vodka to reduce excess moisture, resulting in a crispier tempura. Some recipes also call for seltzer water instead of regular water to create a lighter and bubblier texture.

To make the batter, mix the dry ingredients in one bowl and the wet ingredients in another bowl. Then, slowly add the dry ingredients to the wet ingredients, mixing until you have a smooth batter. You can also use a premade tempura mix, which you can find at most grocery stores or online. Keep the batter cold to prevent the overdevelopment of gluten, which will affect the texture of the final product. Only mix the batter right before frying.

Before battering the prawns, you can soak them in sake to remove any fishy smells. Then, dip the prawns into a bowl of potato starch to lightly coat them before dipping them into the batter. This helps the batter stick to the prawns.

Pre-cooking prawn treatment

When preparing prawns for air frying, there are several steps you can take to ensure they cook evenly and have an appealing presentation. Firstly, it is important to note that prawns should not be overcrowded in the air fryer basket. Cooking in batches is recommended if you are preparing a large quantity.

An optional step to ensure your prawns have a straight presentation is to make shallow slices crosswise along the underside of each prawn. Then, use your fingers to stretch out the prawn so that it lies straight instead of curled. This is a traditional preparation method for shrimp tempura, but it can be skipped if you are not concerned about the appearance.

Another optional step is to soak the prawns in sake while preparing the batter. This step helps to remove any fishy smells from the prawns before cooking. In a bowl, mix water, mayonnaise, and flour. You can also add salt to taste. This mixture will be used to coat the prawns before they are battered.

After your prawns have been sliced and soaked (if desired), you can begin preparing the batter. In a separate bowl, whisk together cornstarch, flour, club soda, and a beaten egg until well combined. You can also add a small amount of soy sauce to the batter for extra flavour. Now, gently stir the prawns into the batter until they are evenly coated.

Once the prawns are battered, use tongs to hold them by the tail and dip them into the flour mixture, allowing any excess batter to drip off. This step will create a breaded exterior that will help the batter adhere to the prawns and prevent sticking in the air fryer.

Cooking spray and overcrowding

When cooking tempura prawns in an air fryer, it is important to ensure that the prawns are not overcrowded in the basket. Cooking in batches is recommended to prevent overcrowding and ensure even cooking.

Now, let's talk about cooking spray. While some sources strongly advise against using cooking spray in an air fryer, others provide instructions on how to use it correctly. The main concern with cooking spray is that it can damage the non-stick coating of the air fryer basket. This is due to the presence of additives, propellants, and other ingredients in the spray. Overuse of cooking spray can also create a buildup of residue, leading to smoke and unpleasant odors.

If you choose to use cooking spray, it is recommended to follow these guidelines:

  • Choose a high-quality cooking spray specifically designed for air frying or non-stick cookware. Look for labels that indicate it is safe for non-stick surfaces and avoid aerosol sprays.
  • Remove the basket from the air fryer before spraying. Hold the spray at least 6 inches away from the basket and apply a light, even coat. Avoid spraying too closely or using too much, as this can cause pooling and create a sticky residue.
  • Alternatively, spray the food directly with cooking spray instead of the basket. This helps reduce residue buildup.
  • Clean the air fryer basket thoroughly after each use to prevent residue buildup.

It is worth noting that some sources suggest using pure oil or a small amount of fat to coat the food or the basket instead of cooking spray. This can help prevent sticking while avoiding the potential issues associated with cooking spray.

Serving suggestions

Tempura prawns are incredibly versatile and can be served with a variety of dishes. Here are some serving suggestions:

Dipping Sauces

You can serve tempura prawns with a variety of dipping sauces. Some popular options include tempura sauce, sweet chilli sauce, or spicy mayo. You can also get creative and make your own dipping sauce by whisking together soy sauce, sherry, rice wine vinegar, oyster sauce, scallions, sugar, lemon juice, and ginger stir-in paste.

Side Dishes

Tempura prawns can be served with a variety of side dishes, such as steamed rice and stir-fried vegetables. If you're looking for a more substantial meal, you could serve the prawns with a side of noodles or fried rice.

Appetizers or Main Course

Tempura prawns can be served as an appetizer or a main course. As an appetizer, they can be served in smaller portions, with a dipping sauce and some light sides, such as a green salad or vegetable sticks. As a main course, you could serve a larger portion of prawns with more substantial sides, such as rice and vegetables.

Other Tempura Options

If you're a fan of tempura, you can also serve tempura prawns with other types of tempura. Some options include vegetable tempura, such as sweet potato or green beans, or even tempura chicken. This can add variety to your meal and showcase the versatility of tempura cooking.

Cooking Methods

While air-fried tempura prawns are a healthier alternative to deep-fried prawns, you can also experiment with different cooking methods. Traditional tempura is deep-fried, resulting in a crispy and indulgent treat. However, you can also bake or grill prawns for a lighter option, although the texture and taste will be different.

Remember, when serving tempura prawns, it's important to ensure they are hot and freshly cooked, as they are best enjoyed straight out of the air fryer.
