I love to serve this dressed-up version of a tuna casserole. The green beans add nice texture, color and flavor. The first time I made this dish, my uncle asked for seconds even though tuna casseroles are not usually his favorite. —Jone Furlong, Santa Rosa, California

Ingredients

  • 1/2 cup water
  • 1 teaspoon chicken bouillon granules
  • 1 package (9 ounces) frozen cut green beans
  • 1 cup chopped onion
  • 1 cup sliced fresh mushrooms
  • 1/4 cup chopped celery
  • 1 garlic clove, minced
  • 1/2 teaspoon dill weed
  • 1/2 teaspoon salt
  • 1/8 teaspoon pepper
  • 4 teaspoons cornstarch
  • 1-1/2 cups cold whole milk
  • 1/2 cup shredded Swiss cheese
  • 1/4 cup mayonnaise
  • 2-1/2 cups egg noodles, cooked and drained
  • 1 can (12 ounces) light tuna in water, drained and flaked
  • 1/3 cup dry bread crumbs
  • 1 tablespoon butter

Directions

  1. In a large saucepan, bring water and bouillon to a boil; stir until bouillon is dissolved. Add the next eight ingredients; bring to a boil. Reduce heat; cover and simmer until vegetables are tender, about 5 minutes.
  2. In a small bowl, combine cornstarch and milk until smooth; gradually add to vegetable mixture. Bring to a boil; cook and stir until thickened, about 2 minutes. Remove from the heat; stir in cheese and mayonnaise until cheese is melted. Fold in noodles and tuna.
  3. Pour into a greased 2-1/2-qt. baking dish. In a small skillet, brown bread crumbs in butter; sprinkle over casserole. Bake, uncovered, at 350° until heated through, 25-30 minutes.
