What You'll Learn

Choosing the right sardines
When choosing sardines to cook in an air fryer, you should consider both the type of sardines and their freshness.
Type of Sardines
Sardines are typically sold either fresh or canned. Fresh sardines will have a richer flavour and texture and are better suited for air-frying. Canned sardines are typically packed in water, olive oil, or soybean oil and are ready to eat, often served on crackers or salads. They can also be used in recipes like pasta sauces or fried until crisp. However, canned fish is usually packed in oil, so if you are conscious about the fat content of your meal, fresh sardines may be a better option.
Freshness of Sardines
When selecting fresh sardines, look for those with bright blue silvery skin that is shiny and elastic, and firm and oily flesh. The eyes should be clear and glossy, and the fish should have a mild sea or fishy smell, not an unpleasant odour. Avoid sardines with bruises or those that appear smashed or soft. Fresh sardines are highly perishable, so it is best to cook them within a few days of purchasing.
Preparation
Before cooking, sardines should be cleaned and gutted. While some people prefer to remove the intestines, head, and bones, it is not necessary for smaller sardines. Leaving the intestines intact will not affect the taste, but some people choose to remove them for aesthetic or textural reasons.

Preparing the fish
When selecting fresh sardines, look for fish with bright blue silvery skin and firm, oily flesh. The fish should be free of bruises and should not be smashed or soft. Its eyes should be clear and glossy, not cloudy. It is best to cook fresh sardines within a few days of purchasing. If you start with frozen fish, make sure to thaw them first by leaving them on the counter for a couple of hours.
Before cooking, you will need to clean and gut the sardines if they have not already been prepared this way by your fishmonger. To do this, slice the fish open lengthwise and remove the intestines. You can also choose to remove the heads and bones, or leave them in if they are small and soft. Rinse the fish well to get rid of any remaining blood or membranes.
To prepare the sardines for cooking, you can lightly coat them with olive oil and seasonings, or dredge them in breadcrumbs for a crispier texture. One seasoning combination you can try is flour, salt, pepper, sugar, and chilli. You can also add more spices like chilli powder, turmeric, garlic powder, and cilantro.

Seasoning and coating
Firstly, you can opt for a dry coating. In a bowl, mix flour with your desired spices. You can use chilli powder, turmeric, garlic powder, salt, and pepper for a flavourful blend. Dredge the sardines in this mixture, ensuring each fish is well coated. This method will create a delicious, crispy exterior on your sardines.
Alternatively, you can create a wet batter by adding liquid to the flour and spice mixture. The wet batter will result in a different texture than the dry coating, so you can choose based on your preference.
If you're using canned sardines, you might want to try breading them before air frying. Coat the sardines with dried breadcrumbs, preferably panko, a Japanese-style breadcrumb. You can also create a seasoned breadcrumb mixture with spices like smoky paprika, cayenne pepper, and freshly cracked black pepper for an extra kick of flavour. This breading technique will give your sardines a delightful crispy texture.
For fresh sardines, Chef Charlotte Langley recommends lightly coating them with olive oil and seasonings before placing them in the air fryer. This method ensures the sardines cook up nice and crispy.
Additionally, you can experiment with different types of flour for the coating. Some people suggest using rice flour, as in tempura, for a unique flavour and texture. Potato or corn starch are also viable options, with potato yielding a crispier result.
Don't be afraid to get creative with your seasonings and coatings. You can tailor the flavours to your personal preference, adding more or less spice as desired. Play around with different combinations of spices and coatings to find your perfect air-fried sardine recipe!

Cooking time and temperature
The cooking time and temperature for sardines in an air fryer depend on whether you are cooking with fresh or canned sardines. Fresh sardines should be cooked for 8 to 10 minutes at 375 degrees Fahrenheit (190 degrees Celsius) until the skin is crispy. If you are using frozen fish, be sure to thaw them first. Canned sardines, on the other hand, only need a few minutes in the air fryer to warm up and get a slight crisp.
When cooking fresh sardines, it is recommended that you lightly coat them with olive oil and seasonings before placing them in the air fryer. You can season the fish with a variety of spices, such as chili powder, turmeric, garlic powder, and salt. Some people also like to add chopped cilantro and green onions on top of the cooked sardines for extra flavor and crunch.
It is important to note that the cooking time may vary depending on your air fryer model. For example, one person reported cooking sardines in their air fryer at 300 degrees for about 8 minutes, but they mentioned that their air fryer runs really hot, so you may need to adjust the temperature and timing accordingly.
When arranging the sardines in the air fryer basket, make sure not to crowd the pan. Assemble the sardines in a single layer to ensure even airflow. You should also flip the sardines halfway through the cooking process to ensure even cooking on both sides.

Serving suggestions
Air-fried sardines can be served with your favourite sauce and side dish. For a side, you could try something like a salad, roasted vegetables, or potatoes. For sauces, consider something like a garlic aioli, a spicy mayo, or a simple lemon wedge.
If you're using canned sardines, you can dredge them in breadcrumbs before air-frying to give them a super crispy texture. You can also serve these with ketchup and mustard.
If you're looking for a more substantial meal, you could serve the sardines with a grain like rice, quinoa, or couscous. You could also try serving them with a pasta or noodle dish, perhaps with a lemon and garlic dressing.
For a more sophisticated meal, consider serving the sardines with a white wine sauce, or a beurre blanc, and some steamed vegetables or greens.
If you're cooking for a crowd, you could serve the sardines as part of a mezze or tapas-style spread, with dishes like hummus, baba ganoush, olives, and flatbreads.
Finally, if you're short on time, you could simply serve the sardines with some crackers or crusty bread, and perhaps a dip or spread, like tzatziki or hummus.
