Instructions:

  1. Preheat oven to 350°F (175°C).

  5. Reduce heat to low and simmer for 5-7 minutes, stirring occasionally, until the sauce has thickened.
  6. Remove from heat and stir in salt, pepper, nutmeg (if using), and 1 cup of cheddar cheese until melted and smooth.
  7. Gently fold in the drained tuna, peas, and pimentos (if using) into the cheese sauce.
  8. Add the cooked noodles to the sauce and stir gently to combine.
  9. Pour the noodle mixture into the prepared baking dish.
  10. In a small bowl, combine crushed potato chips with melted butter.
  11. Sprinkle the remaining 1 cup of cheddar cheese over the casserole, followed by the potato chip topping.
  12. Bake for 20-25 minutes, or until golden brown and bubbly.
  13. Let stand for 5-10 minutes before serving. Enjoy your Tuna Noodle Casserole!
