*Ingredients:
° 1 tablespoon of butter
° 1/2 onion, chopped
° 1/4 cup melted butter
° 1/4 cup flour
° 2 cups of milk
° 2 cups of chicken broth
° 1 1/2 cup coarsely chopped broccoli florets
° 1 cup carrots cut into matchsticks
° 1 stalk celery
° 2 1/2 c Cheddar cheese
° Salt & ground black pepper
* Methods
Melt 1 tablespoon of butter in a skillet over medium-high heat. Sauté onion in hot butter until translucent, about 5 minutes. Put aside.
Whisk 1/4 c butter / flour together in saucepan over medium-low heat; cooking to flour loses its graininess, adding 1 to 2 tablespoons milk if necessary to prevent flour from burning, 3 to 4 minutes.
Gradually pour the milk into the flour mixture, whisking constantly. Stir the chicken broth into the milk mixture.
Bring to the boil; cook until the flour taste disappears and the mixture thickens, about 20 minutes.
Adding broccoli, carrots, sautéed onion and celery; simmer until vegetables are tender, about 20 mn.
