Ingredients:
1 tablespoon unsalted butter
1/2 white onion, chopped
1/4 cup melted butter
1/4 cup flour of your choice
2 cups milk of your choice
2 cups low sodium chicken stock
1 1/2 cups chopped broccoli florets
1 cup matchstick cut carrots
1 stalk celery, thinly sliced
2 1/2 cups shredded sharp Cheddar Cheese
Directions:
Melt 1 tablespoon of butter in a skillet over medium-high heat. Saute onion in hot butter until translucent, about 5 minutes. Set aside. Whisk 1/4 cup melted butter and flour together in a large saucepan over medium-low heat; cook until the flour loses it's granular texture, adding 1 to 2 tablespoons of milk if necessary to keep the flour from burning, 3 to 4 minutes. Gradually pour milk into flour mixture while whisking constantly. Stir chicken stock into milk mixture. Bring to a simmer; cook until mixture is thickened, about 20 minutes. Add broccoli, carrots, sauteed onion, and celery; simmer until vegetables are tender, about 20 minutes. Stir cheddar cheese into vegetable mixture until cheese melts. Season with salt and pepper to taste.
