Cheddar Cheese Soup

Heat butter in a 3-quart saucepan over high heat, stirring occasionally until melted. Add the sliced onion and sauté for approximately 5 minutes or until it reaches a tender state. Combine the cooked onion with flour to create a mixture that will thicken as it cooks, stirring constantly. Gradually add the broth and continue to cook, stirring continuously, until the mixture has thickened slightly. Introduce milk into the saucepan and cook, stirring constantly, until just a gentle boil is achieved.

To achieve a smooth consistency, blend the soup in small batches using a blender until it reaches your desired level of smoothness.

Transfer the blended soup back to the saucepan and cook over a medium heat source until just a gentle boil is reached. Remove from the heat source and whisk in cheese until it has fully melted.
