Air Fryer Recipe
Spicy Sardine Croquettes
Spicy sardine croquettes are a delicious and easy-to-make dish with a crispy exterior and a rich, flavourful filling, perfect for air frying.
Ingredients
- 2 tins of sardines in oil (approximately 240g)
- 2 medium potatoes, boiled and mashed
- 1 small onion, finely chopped
- 1 garlic clove, minced
- 1 red chilli, finely chopped
- 1 tablespoon fresh parsley, chopped
- 1 tablespoon lemon juice
- 1 teaspoon smoked paprika
- Salt and pepper to taste
- 1 egg, beaten
- Breadcrumbs, for coating
- Olive oil spray
Method
- Drain the sardines and mash them in a large bowl with a fork. Mix with mashed potatoes, onion, garlic, chilli, parsley, lemon juice, smoked paprika, salt, and pepper.
- Form the mixture into small, oval-shaped croquettes, ensuring they are tightly packed.
- Dip each croquette into the beaten egg, then roll in breadcrumbs until fully coated. Refrigerate for at least 30 minutes.
- Preheat air fryer to 200°C (400°F). Lightly spray croquettes with olive oil and place in air fryer basket. Cook for 10-12 minutes until golden brown and crispy, shaking the basket halfway through.
Why this works in an air fryer
Mashed potato binds the oily sardines and buffers the chilli and garlic, while chilling firms the starch so the croquettes hold their shape. The egg-and-breadcrumb shell dries quickly in the air fryer’s fast convection; a light oil spray fills breadcrumb gaps, helping even browning without deep-frying.
Equipment notes
Assumes a 4-6 litre basket with the croquettes in one layer and at least 1 cm between them. In a single-drawer air fryer, cook one batch at a time for strongest airflow; in a dual-zone model, split evenly between drawers and check 1-2 minutes early, as smaller loads often brown faster at the outer edges.
Common pitfalls
- Croquettes cracking open before browning? The mix is too warm or loose; chill longer and, if needed, fold in a spoonful of breadcrumbs before shaping.
- Patchy pale crumbs after 10 minutes? The coating is too dry or unsprayed; mist lightly with oil and cook 2-3 minutes more, turning once.
- Soggy underside with a browned top? The basket is overcrowded or the croquettes are sitting in fish oil; leave space between pieces and drain the sardines thoroughly before mixing.
- Onion tasting raw in the centre? The pieces are too large for the short air-fryer cook; chop very finely or briefly soften the onion before mixing.
Variations & substitutions
- Use panko instead of standard breadcrumbs for a rougher crust; it browns more quickly, so start checking at 9 minutes.
- Swap red chilli for chilli flakes or harissa; paste-style heat adds moisture, so add a little extra breadcrumb if the mixture feels slack.
- Use tinned mackerel instead of sardines for a richer filling; drain it well, as the higher oil content can soften the coating.
- Add a teaspoon of capers or chopped gherkin for sharpness; keep pieces small so they do not split the croquettes during shaping.
Storage & reheating
Keep cooked croquettes chilled for up to 2 days, then reheat in the air fryer at 180°C for 5-7 minutes until hot through and crisp again.
