My family digs into this moist, flavorful tuna casserole. Crisp celery along with zucchini and tomato give it a fresh twist. When I get home from work and we have to be somewhere else in 90 minutes, this is the recipe I rely on.

Ingredients

  • 1/2 cup sour cream
  • 1/2 cup mayonnaise
  • 2 teaspoons prepared mustard
  • 1/2 teaspoon salt
  • 1/2 teaspoon dried thyme
  • 1/4 teaspoon dill weed
  • 5 cups cooked egg noodles
  • 2 cans (6 ounces each) tuna, drained and flaked
  • 1/2 cup chopped celery
  • 1/3 cup sliced green onions
  • 1 small zucchini, sliced
  • 1 cup shredded cheddar cheese
  • 1 medium tomato, chopped

Directions

  1. In a small bowl, combine the first six ingredients; mix well. In a large bowl, combine noodles, tuna, celery and onions. Stir in the sour cream mixture. Spoon half into a greased 2-qt. microwave-safe dish; top with half of the zucchini. Repeat layers.
  2. Microwave, uncovered, on high for 4-6 minutes or until heated through. Sprinkle with cheese and tomato. Microwave, uncovered, 1 minute longer. Let stand for 3 minutes before serving.
