- 2 tablespoons butter
- 1/2 cup all-purpose flour
- 1/2 cup milk, plus more if needed
- 1 (10.75 ounce) can condensed tomato soup
- 3/4 cup cubed Cheddar cheese
- 1/2 teaspoon dry mustard powder (optional)
- 1 dash Worcestershire sauce (optional)
- 1 pinch ground paprika (optional)
- Melt the butter in a saucepan over low heat, then whisk in the flour to form a thick paste. Slowly whisk in the milk until the mixture resembles a thick sauce. Stir in the tomato soup, Cheddar cheese, mustard, Worcestershire sauce, and paprika until heated through, about 10 minutes. Add more milk if the soup becomes too thick.
