- Preheat oven to 350 F and spray a 13x9 inch baking dish with non-stick spray.
- Melt butter in a large saucepan over medium heat. Add shallot and paprika and sauté for about 5 minutes or until soft. Add flour and stir constantly for one minute. Gradually whisk in the LACTAID® Milk until the mixture is smooth. Whisk in the salt, mustard, black and cayenne pepper. Continue to whisk until the sauce thickens and comes to a boil, about 5 minutes. Gradually stir in the cheeses, and remove from heat. Continue stirring until all cheese has melted and is incorporated smoothly into the sauce.
