Quick answer: The best fish seasoning for a UK home cook is a light, citrus-forward blend that lifts the fish without burying it. It needs gentle paprika, garlic, herbs and a citrus note, with no MSG or fillers. Costack Fish & Seafood Seasoning is a smoky-citrus rub built for cod, salmon, tilapia and prawns at ยฃ8.50.
Why fish needs its own seasoning
Fish is delicate. Season it like beef and you lose it. The flavour of cod, haddock, salmon or sea bass is part of the point, so the seasoning has to support the fish rather than cover it.
That is why a general all-purpose blend often falls flat on fish. It is built salt-heavy and savoury for meat. Fish wants brightness, a little smoke and a citrus edge.
What to look for in 2026
- A citrus note. Lemon or a citrus-leaning spice cuts through the richness of oily fish and freshens white fish.
- Gentle paprika. Enough for colour and a soft smoky warmth, not enough to dominate.
- Herbs over heavy spice. Parsley, thyme and dill-style notes suit fish. Heavy earthy spice does not.
- Light salt. Fish needs seasoning, not curing. The salt should be present but restrained.
- Works wet and dry. A good fish blend should rub onto a fillet, stir into a marinade, or drop into a fish stew.

How to season fish properly
For a pan-fried fillet, pat the fish dry, brush with a little oil, then season both sides just before it hits the pan. Dry fish plus a hot pan gives you a proper crust.
For baked fish, season, add a squeeze of fresh lemon, and let it sit for ten minutes. Any longer and the salt starts to firm the texture.
For a fish stew or curry, season the fish lightly and build the rest of the flavour into the base. For seafood soups, risotto and paella, a shellfish stock powder does more than a surface rub, because it seasons the whole liquid.
