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 the oven: Preheat your oven to 350°F and spray a 9×13-inch casserole dish with non-stick cooking spray to prepare it for the casserole.
  2. Mix the casserole ingredients: In a large bowl, combine the cooked egg noodles, frozen peas, drained tuna, cream of mushroom soup, whole milk, 1¼ cups shredded mild cheddar cheese, celery salt, pepper, and chopped parsley. Stir gently until everything is evenly mixed.
  3. Assemble the casserole: Transfer the tuna mixture into the prepared casserole dish, spreading it out evenly for uniform baking.
  4. Bake covered: Cover the casserole dish with foil or a lid and bake in the preheated oven for 20 minutes, until the mixture is hot and bubbly.
  5. Prepare the topping: While the casserole is baking, mix the bread crumbs with the melted butter until the crumbs are well coated.
  6. Add the topping and cheese: After 20 minutes, remove the casserole from the oven. Sprinkle the buttered bread crumbs evenly over the top, then add the remaining ¼ cup shredded mild 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 lightly browned and the cheese is melted and bubbling.
  8. Serve: Remove from the oven and let it cool slightly. Garnish with additional fresh parsley if desired. Serve warm and enjoy your comforting tuna casserole.

Notes

  • You can substitute cream of mushroom soup with cream of celery or cream of chicken soup for flavor variation.
  • Use fresh parsley for best flavor, but dried parsley can be substituted in a pinch at one-third the quantity.
  • For a gluten-free version, use gluten-free egg noodles and gluten-free bread crumbs.
  • Make sure to drain tuna well to avoid excess moisture in the casserole.
  • The casserole can be prepared ahead of time and refrigerated before baking; increase baking time by a few minutes if baking cold.
