Tinned Sardine Recipes: Crispy Sardine Croquettes

Some pantry ingredients wait patiently at the back of the cupboard. Others are ready to become something unexpectedly delicious.

A tin of Brunswick Sardines in Water – No Added Salt falls firmly into the second category. Combine these flavour-packed little fish with rustic mashed potato, fresh parsley, capers and horseradish, and you have crispy sardine croquettes worthy of considerably more attention than their simple ingredients suggest.

Golden on the outside and soft and savoury in the middle, these croquettes are ideal as an appetiser, party snack or easy family meal. Serve them hot with a creamy yoghurt and horseradish dipping sauce—and perhaps make more than you think you need.

Why You’ll Love These Sardine Croquettes

Sardines are one of the most useful ingredients to keep in the pantry. They are convenient, versatile and full of savoury flavour, making them perfect for quick meals when the refrigerator is looking less than inspiring.

This sardine croquette recipe transforms everyday ingredients into something crisp, comforting and wonderfully satisfying. The potatoes create a fluffy centre, while parsley, onion and capers add freshness and bite. Horseradish brings a gentle warmth that works beautifully with the sardines without overpowering them.

Then there is the crunchy breadcrumb coating. Because every good croquette should make a little noise when you bite into it.

Ingredients

For the Sardine Croquettes

• 3 medium potatoes, approximately 380 g
• 1 × 106 g tin Brunswick Sardines in Water – No Added Salt, drained
• 25 g parsley, finely chopped
• ½ brown onion, approximately 55 g, finely diced
• Alternatively, use 25 g chopped chives
• 6 capers, finely chopped
• ¼ teaspoon salt
• ¼ teaspoon black pepper
• 1½ cups breadcrumbs, approximately 95 g
• ¾ teaspoon horseradish
• 1 egg, lightly beaten
• Cooking oil, for shallow frying

For the Creamy Yoghurt Dipping Sauce

• 1 tablespoon parsley, finely chopped
• ½ teaspoon horseradish
• ⅓ cup whole-egg mayonnaise
• 2 tablespoons Greek yoghurt

How to Make Crispy Sardine Croquettes

Leave the skins on the potatoes for extra texture and a more rustic finish. Cut them into pieces approximately 4 cm wide, place them in a medium saucepan and cover with water.

Bring the water to the boil, then reduce the heat and simmer for 10–15 minutes. Once the potatoes are tender, drain them well and roughly mash them with a fork. Set aside for 10–15 minutes to cool.

Place the cooled potato in a medium mixing bowl. Add the drained Brunswick sardines, chopped parsley, onion or chives, capers, salt, pepper, breadcrumbs, horseradish and beaten egg.

Mix until the ingredients are evenly combined. A fork works well here and helps break up the sardines while keeping some texture in the filling.

Shape tablespoon-sized portions of the mixture into balls or small sausage-shaped croquettes approximately 7 cm long. Place them on a tray, cover and refrigerate for 30 minutes. Chilling helps the croquettes firm up and hold their shape while frying.

Pour enough oil into a medium frying pan to reach approximately 2 cm deep. Heat the oil over medium-high heat, then carefully cook the croquettes in three batches.

Fry them for a few minutes on each side until crisp, golden and heated through. Avoid overcrowding the pan, as this can lower the oil temperature and prevent the croquettes from becoming properly crunchy.

Remove the cooked croquettes using a slotted spoon and transfer them to a plate lined with paper towel. Repeat with the remaining mixture.

Make the Creamy Yoghurt Dipping Sauce

While the croquettes are cooking, combine the chopped parsley, horseradish, whole-egg mayonnaise and Greek yoghurt in a small bowl.

Taste the sauce and adjust it to your liking. Add a little more horseradish if you enjoy extra heat, or another spoonful of yoghurt for a lighter, tangier finish.

How to Serve Sardine Croquettes

These crispy sardine croquettes are best served immediately while the outside is hot and crunchy.

Serve them as:

• A party appetiser with the yoghurt dipping sauce
• A light lunch with a fresh green salad
• A casual dinner with roasted vegetables
• A share-plate snack with lemon wedges and extra capers
• A delicious filling for wraps or soft rolls

For entertaining, arrange the croquettes on a platter with the dipping sauce in the centre. Finish with fresh parsley and lemon wedges for a simple presentation that looks far more complicated than it actually was.

Tips for Perfect Croquettes

Allow the mashed potato to cool before adding the remaining ingredients. Warm potato can make the mixture too soft and difficult to shape.

Do not skip the refrigeration time. Those 30 minutes help the croquettes stay together when they meet the hot oil.

Cook in batches and give each croquette enough room in the pan. A crowded frying pan usually leads to uneven cooking and less crunch.

Finally, keep an eye on the oil temperature. If it is too cool, the croquettes may absorb excess oil. If it is too hot, the outside may brown before the centre is properly heated.
