Step 1Melt the butter in a medium saucepan over medium heat. Add the onion and garlic and cook, stirring, until the onion has softened and the garlic is very fragrant, about 5 minutes. Stir in the rice, then add the water or chicken broth and salt and pepper to taste. Bring to a boil then reduce the heat to low, cover and simmer until the rice is tender and the liquid has been absorbed, about 15 minutes. Stir in the mint.
