Instructions

  1. Preheat oven to 425* F. Cook noodles according to package directions. Drain and return to pan.
  2. Meanwhile, pour soup into a small saucepan. Slowly stir in milk, a little at a time. Stir in cheese. Heat over medium-low heat, stirring often, until hot and cheese is melted; do not boil.
  3. Add tuna, onion, celery, mayonnaise, and salt and pepper to taste to the noodles and stir together. Pour soup mixture over and mix until well-combined. Pour mixture into a 2-2 1/2 quart casserole. Top with additional shredded cheese, if desired.
  4. Place casserole in oven and bake at 425* F for 20-25 minutes, or until hot, bubbling, and lightly browned on top. Remove from oven and let set for 5-10 minutes before serving.
