Ingredients
- 1 tbsp olive oil, plus 1 tsp to drizzle
- 1 small onion or large shallot, finely diced
- 1½ tbsp plain flour
- 200ml fish or vegetable stock (made using ½ stock cube)
- 100g sugar snaps
- 1 x 125g tin mackerel fillets in brine, drained and flaked
- 1 x 105g tin Wild Pacific red salmon, drained and flaked
- 1 x 198g tin sweetcorn, drained
- 4 tbsp lighter crème fraîche
- 50g grated lighter mature cheese
- 75g ciabatta, torn into small chunks
Step by step
- Preheat the oven to 240°C, fan 220°C, gas 9.
- Heat 1 tablespoon of olive oil in a large saucepan and gently fry the onion for 3-4 minutes until it starts to soften. Stir in the flour and cook for 1-2 minutes, stirring. Gradually pour in the stock, stirring, until the sauce begins to thicken.
- Add the sugar snaps and simmer for 2 minutes, then stir in the mackerel, salmon and sweetcorn along with the crème fraîche. Warm through for 2 minutes and then remove from the heat. Stir in the cheese until melted. Season to taste.
- Tip into an ovenproof dish (about 18cm diameter) and top with the ciabatta. Drizzle over 1 teaspoon of oil and bake for 8-10 minutes until golden brown, crisp and bubbling.
Good to know
Tinned fish is not only a great storecupboard standby, it’s budget- friendly and minimises food waste, too. Oil-rich fish, such as mackerel and salmon, are packed with heart- healthy omega-3 fats and the canning process preserves it at its peak.
