Simply use it as a vegetable. Yes, really. Stir-fries. Soups, especially soups. Try wilting handfuls of it into a nice stock with, say, fish balls. Or a tangy soup with chicken and bunches of trimmed basil. Use it as one would fistfuls of Thai basil in similar circumstances except with a slight twist to it.
(In fact, half of what you have in that tub would easily go into ONE pot of soup for just a couple meals, or, if I'm hungry, a single meal. :-) )
ETA2: 10-15 years ago, when I was much more enthusiastic about growing stuff, I would have about 20 feet-worth of beds growing just basil of various sorts - usually around 7 -8 types plus more in tubs on the deck. Standard Italian-type (like yours) and Genovese would be two of the more dominant varieties. I'd let them get to about 3 times the height of what you show, with appropriate feeding. Yes, I ate them all - except the more scented or unusual ones which were only partially consumed.
