Step 1Warm the chicken stock in a small saucepan over medium-low heat.
Step 2Melt the butter in a saucepan over medium heat. Add the onion and cook until softened, 2 to 3 minutes. Add the rice and stir to coat with the butter and onion. Pour in the warm chicken stock, add the bay leaf and bring to a boil. Cover, reduce the heat and simmer until the liquid has evaporated and the rice is tender, about 20 minutes. Remove the bay leaf and season to taste with salt and pepper.
