Pouring creamy white sauce onto a layered lasagna.

The ad opens with a close-up of a person pouring a white sauce from a carton labeled 'CHEF Besciamella' onto a lasagna in a white baking dish. The lasagna is layered with red sauce and pasta. The scene then shifts to the lasagna being placed into an oven. Finally, a slice of cooked lasagna is shown on a plate next to the carton of sauce and a potted basil plant, with text overlay.
