For Classic Tuna Noodle Casserole and Cheddar Cheesy Classic Tuna Noodle Casserole

  1. Cook noodles according to package directions in a large stock pot.  Drain and set aside.
  2. Using the same stock pot used for the noodles, melt the butter over medium heat.  Add the flour all at once and whisk until the flour and the butter are completely combined.  
  3. Slowly whisk in the milk and cook until smooth with no lumps.
  4. Whisk in the cheese based upon the recipe you’re making (sliced cheese and cheese powder) or (shredded cheddar) until melted and smooth.
  5. Transfer the drained macaroni to the pot and stir to coat with the cheese sauce.
  6. Add the tuna, mixed vegetables and chopped mushrooms.  Stir to combine.
  7. Sprinkle panko crumbs over the casserole and serve hot.


You can reduce the fat and calories of this recipe by using skim milk and lower fat cheese.

Either recipe is great.  The Cheddar Cheesy Classic is a cheesier version of the original and is included for those that don’t have the White Cheddar Cheese Powder.
