Kosher for Passover Fish

Kosher for Passover fish can be a great protein option, but it’s important to ensure it meets strict Passover guidelines. Fresh fish is generally acceptable as long as it is a kosher species (with fins and scales), but it must be properly cleaned and prepared with kosher-for-Passover utensils to avoid cross-contamination with chametz. When buying packaged or processed fish—such as canned tuna, smoked salmon, gefilte fish, or frozen fillets—always look for a reliable Kosher for Passover (KFP) certification, as these products may contain additives, broths, or preservatives that are not permitted during Passover. Be particularly cautious of flavourings, spice mixes, or marinades, which can include hidden chametz or kitniyot ingredients. Avoid breaded fish, fish cakes, or anything coated in flour or crumbs, and check that oils used in preservation are KFP-approved. When in doubt, opt for plain, fresh fish and prepare it simply at home to ensure full compliance.
