Ingredients
¼ cup butter, melted, plus 1 tablespoon butter, separated
½ onion, chopped
¼ cup flour
2 cups milk
2 cups chicken stock
1€‰Â½ cups coarsely chopped broccoli florets
1 cup matchstick-cut carrots
1 stalk celery, thinly sliced
2€‰Â½ cups shredded sharp cheddar cheese
Salt and ground black pepper to taste

Directions
1.Melt 1 tablespoon butter in a skillet over medium-high heat. Saute
onion in hot butter until translucent, about 5 minutes. Set aside.

2.Whisk 1/4 cup melted butter and four together in a large saucepan over
medium-low heat; cook until four loses its granular texture, adding 1 to
2 tablespoons of milk if necessary to keep the four from burning, 3 to 4
minutes.

3. Gradually pour milk into the flour mixture while whisking constantly.
Stir chicken stock into milk mixture. Bring to a simmer; cook until
flour taste is gone and the mixture is thickened (about 20 minutes). Add
broccoli, carrots, sauteed onion, and celery; simmer until vegetables
are tender, about 20 minutes.

4. Stir Cheddar cheese into vegetable mixture until cheese melts.
Season with salt and pepper to taste
