Tilapia with potatoes and spices in the oven is a dish rich in a variety of flavors and aromas. The background of this bouquet is created by rosemary, basil, lemon juice, and the flavor range is created by potatoes, butter, mayonnaise, cheese, and vegetables. The main thing in cooking is that everything is covered with foil on a baking sheet and simmered, as in a Russian oven. Hence the special taste of fish.
