This lemon rice recipe is a bright and flavorful side dish. In a medium saucepan, heat 1 tablespoon of olive oil over medium heat. Add 1/4 cup chopped onion and cook until softened, about 3 minutes. Add 1 cup of white rice and stir to coat in the oil. Add 2 cups of chicken or vegetable broth, the zest of 1 lemon, and the juice of 1/2 lemon. Bring to a boil, then reduce the heat to low and cover the pot. Cook for 18-20 minutes, or until the liquid is absorbed and the rice is tender. Fluff with a fork and serve.
