Chicken Asparagus Casserole
  1. 1

    Assemble all ingredients. Preheat the oven to 350 degrees F (175 degrees C). Lightly grease a 1 1/2-quart casserole dish.

  2. 2

    Fill a large pot with lightly salted water and bring it to a rapid boil. Boil the egg noodles until almost tender, about 5 minutes. Drain thoroughly.

  3. 3

    Heat olive oil in a heavy skillet over medium heat; add the onion and cook for 4 to 5 minutes, stirring often. Stir in the cooked chicken, red bell pepper, celery, and chicken stock. Bring to a boil, then simmer for 5 minutes. Mix in the sour cream and oregano.

  4. 4

    Spread half of the chicken mixture in the prepared dish; arrange the asparagus on top. Distribute the cooked noodles evenly over the asparagus and top with 5 tablespoons of Parmesan cheese. Cover with the remaining chicken mixture and sprinkle the remaining 3 tablespoons Parmesan cheese over the top. Bake in the preheated oven until the cheese has melted and the top is golden brown, about 30 minutes.
