Due to the cool climate I sow or buy basil every year, because the frost kills it in winter. I think in warm climates you may able to make it into a perennial by cutting it right back in the autumn, so that it shoots up again in spring. I find Basil grows wonderfully in pots indoors and the aromatic smell engulfs the room. It needs dry light well drained soil and a sunny but sheltered position. Sow seeds in early summer and when matured water the plants well to keep leaves succulent.
Basil is delicious in most dishes. I add the fresh green leaves to the meal right at the very end, so as not to lose the flavour. It tastes scrumptious sprinkled on homemade pizza, homemade spag bol suace, tomato soup, bruschetta, the list is unlimited. Sometimes supermarkets like Dunnes Stores, Tescos or Lidl sell pots of basil at a reasonable price, so have a look out for them. See other herbs you can grow indoors on: Get your Pots out.
