Fish casserole

Cookinero 26 Mar 2025

Fish casserole is a universal dish that almost everyone likes and cooks very quickly. The recipe for fish casserole in the oven requires boneless fish fillet. Delicate fish on a potato bed in sour cream sauce can be made from fillet of sea bass, pollock, tilapia and other types of fish. Fillet is an instant-frozen product, so it always has an ice crust. It should be uniform. This indicates freshness and proper storage of the fish.
