Scale

Main Ingredients

  • 3 cups egg noodles (measured dry, approximately 6 ounces)
  • 1 tablespoon butter
  • 1 small onion, diced
  • 2 ribs celery, diced
  • ⅔ cup frozen peas, thawed
  • 1 (5 ounce) can tuna, drained
  • 1 (10.5 ounce) can condensed cream of mushroom soup
  • ⅓ cup milk
  • 1 cup shredded cheddar cheese
  • 1 tablespoon chopped fresh parsley (or 1 teaspoon dried parsley)

Topping Ingredients

  • ½ cup panko bread crumbs
  • 1 tablespoon melted butter
  • ½ cup shredded cheddar cheese
  • 1 tablespoon chopped fresh parsley (or 1 teaspoon dried parsley)

Instructions

  1. Prepare the topping: Preheat the oven to 425°F. In a small bowl, combine the panko bread crumbs, melted butter, ½ cup shredded cheddar cheese, and chopped parsley. Set this mixture aside for later use as the casserole topping.
  2. Cook the noodles: Bring a pot of water to a boil and cook the egg noodles until al dente according to the package directions. Drain them well and rinse under cold water to stop cooking and prevent stickiness.
  3. Sauté the vegetables: In a skillet, melt 1 tablespoon of butter over medium heat. Add the diced onion and celery and cook for about 5-7 minutes or until they have softened and become tender.
  4. Combine the casserole ingredients: In a large mixing bowl, add the cooked noodles, sautéed onion and celery, thawed peas, condensed cream of mushroom soup, ⅓ cup milk, 1 cup shredded cheddar cheese, drained tuna, and 1 tablespoon chopped parsley. Mix all the ingredients thoroughly to combine evenly.
  5. Assemble the casserole: Spread the combined mixture evenly into a 2-quart casserole dish. Sprinkle the prepared breadcrumb topping evenly over the casserole.
  6. Bake the casserole: Place the casserole dish in the preheated oven and bake for 18-20 minutes, or until the casserole is bubbly and the topping is golden brown.

Notes

  • For extra flavor, you can add a splash of lemon juice to brighten the tuna mixture.
  • Substitute cream of mushroom soup with cream of celery or cream of chicken soup based on taste preferences.
  • Using fresh parsley adds better flavor, but dried parsley works well as a convenient alternative.
  • Ensure noodles are cooked al dente to avoid mushy casserole texture after baking.
  • Panko bread crumbs provide a light, crispy topping; regular crumbs will yield a denser crust.
