Ingredients

Scale

Main Ingredients

  • 6 ounces egg noodles, cooked
  • 1 cup frozen peas
  • 10 ounces tuna, drained (two 5-ounce cans)
  • 10.5 ounces cream of mushroom soup
  • ½ cup whole milk
  • 1½ cups shredded mild cheddar cheese, divided (1¼ cups and ¼ cup)
  • ½ teaspoon celery salt
  • ¼ teaspoon pepper
  • 2 tablespoons fresh parsley, chopped (plus more for garnish if desired)

Topping

  • ¼ cup bread crumbs
  • 2 tablespoons butter, melted

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C) and spray a 9×13-inch casserole dish with non-stick cooking spray to prevent sticking.
  2. Prepare Mixture: In a large bowl, combine the cooked egg noodles, frozen peas, drained tuna, cream of mushroom soup, whole milk, 1¼ cups of shredded mild cheddar cheese, celery salt, pepper, and chopped fresh parsley. Stir well to evenly incorporate all ingredients.
  3. Assemble Casserole: Transfer the tuna noodle mixture into the prepared casserole dish and spread it evenly.
  4. Bake Covered: Cover the casserole dish and bake in the preheated oven for 20 minutes, or until the casserole is hot and bubbling.
  5. Prepare Topping: While the casserole is baking, mix together the bread crumbs and melted butter until the crumbs are evenly coated.
  6. Add Topping: Remove the casserole from the oven after 20 minutes, sprinkle the buttery bread crumbs evenly over the top, and add the remaining ¼ cup shredded cheddar cheese.
  7. Bake Uncovered: Return the casserole to the oven and bake uncovered for an additional 5 to 10 minutes, or until the bread crumbs are golden brown and the cheese is melted.
  8. Serve: Once done, remove from oven, garnish with extra fresh parsley if desired, and serve the casserole warm for a comforting meal.

Notes

  • For a crispier topping, you can broil the casserole for 1-2 minutes after adding the breadcrumbs and cheese—watch closely to avoid burning.
  • Feel free to substitute whole milk with 2% or evaporated milk for a creamier texture.
  • Fresh parsley adds brightness, but you can use dried parsley if fresh is unavailable (use about 1 teaspoon dried).
  • This recipe can be made ahead and stored in the fridge; bake just before serving.
  • Leftovers store well for 2-3 days in the refrigerator and reheat nicely in the oven or microwave.
