Ground pepper, thyme and dill all complement the flavor of rainbow trout. Rainbow trout has a delicate and slightly nutty flavor, so it is important not to choose strong herbs that might overpower the flavor of the fish.
Adding fresh lemon juice, lemon pepper or lemon zest to rainbow trout during the cooking process brings out the taste of the fish and the herbs chosen to accompany it. Baking, grilling, broiling, sautéing, poaching and smoking are all good methods for cooking rainbow trout. It is very important not to overcook rainbow trout, as this destroys the delicate flavor of the fish.
