Haddock is a lean cod-family fish with white flaky fillets and a clean, slightly sweet flavor. Recipes should count the plain fish itself, without flour, breading, sweet marinade, glaze, or excess salt.
Haddock is sold as fillets, whole fish, or steaks. Good fillets hold shape and do not release much cloudy liquid.
Nutrition
Haddock has almost no carbohydrate and very little fat. It is a useful protein base for keto meals when fat is added separately: butter, cream, hollandaise, or olive dressing.
Haddock has essentially no glycemic load as a plain fish: there is no starch or sugar in the flesh. What changes the keto result is the preparation, especially flour, bread crumbs, sweet marinades, sugary glaze, or ready-made sauces served with the fish.
How to Use
Haddock dries out easily. Bake it under sauce, steam with butter, simmer in cream, or use it in fish patties without bread.
For Haddock, weigh the edible part you actually cook or serve: fillet without large bones, trimmed steaks, or the cleaned whole fish portion. Because this is not a very fatty fish, keto recipes usually need butter, olive oil, egg-yolk sauce, cream, or another fat source.
How to Choose
When buying Haddock, look for clean smell, resilient flesh, natural color, and packaging without excess cloudy liquid. Whole fish should have clear eyes and intact skin; fillets should not be dry at the edges or sticky on the surface.
Storage and Safety
Keep Haddock chilled until cooking and thaw frozen pieces slowly in the refrigerator. Cook fish thoroughly when the source is uncertain, avoid repeated thawing, and treat any strong ammonia smell as a reason to discard the product.
