Instructions
Blitz the tinned tomatoes and their juice in a food processor for 30 seconds.
Prepare the tomato sauce. Heat the oil in a pan and sweat the onions for 5 minutes with a pinch of salt.
Add the garlic, tinned tomatoes, paste, sugar and paprika and bring to a rolling simmer.
Cook for 10 minutes until the sauce is slightly reduced. Taste, and season with salt and pepper.
Heat the oven to 180C (350F). Drizzle olive oil over a large sheetpan and put in the oven to heat up.
Peel and cube the potatoes and then pat dry with kitchen paper.
Spread the potatoes on the prepared sheet pan, tossing to coat in the hot oil. Season with salt.
Bake for 40 minutes, turning them over once or twice so that they crisp up evenly.
Place the fish on an oiled tray and season with salt. Top each fillet with a spoonful of the sauce and bake for 15 minutes - just pop them in the oven with the potatoes towards the end of their cooking time.
Top the crisp potatoes with the tomato sauce, add a pinch dried chilli flakes, and garnish with the chopped parsley.
Serve either with the sea bass as a main or as a starter to share.
