How to Stew Fish
Ingredients
Directions
Prepare the fish
In a pan, melt the butter and fry the chopped onions until they are brown, stirring frequently.
Dust the fish with flour and fry it in the same butter until cooked through.
Stew and serve
Transfer the browned onions and butter into a stew pan with the fish.
Cover and let it stew gently over low heat for about an hour.
Serve the fish with the gravy poured over it, garnished with lemon slices and fried bread.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Fats the pan and carries the browning flavour from the onions into the stew.
- Onions
- Browned onions add sweetness and savoury depth that flavour the gravy.
- Flour
- Dusting the fish helps it brown and thickens the gravy slightly.
- Fish
- The main protein, which becomes tender as it cooks gently in the stew.
The step that matters
Cover and let it stew gently over low heat. Low, gentle heat keeps the fish tender and lets the liquid turn into a flavourful gravy without the fish breaking apart or toughening.
