Ingredients

This is just a quick overview of the ingredients that you’ll need for a chicken mushroom casserole. As always, specific measurements and step-by-step cooking instructions are included in the printable recipe box at the bottom of the post.

  • Condensed cream of mushroom soup: I typically use the Campbell’s Healthy Request variety, but any similar option will work well.
  • Milk: a little bit of liquid to thin the soup and make the creamy sauce.
  • Low-sodium chicken broth or water: to thin the sauce and to provide some extra cooking liquid for the pasta to absorb as it softens.
  • Dried thyme, kosher salt, garlic powder, and ground black pepper: simple seasonings that give the dish a little bit of extra flavor.
  • Mushrooms: pick up a container of pre-sliced fresh mushrooms for even quicker prep — no cleaning or cutting required! White button mushrooms, baby bella mushrooms, and cremini mushrooms will all work.
  • Chicken: cut up raw, boneless, skinless chicken breast into bite-size pieces. The meat will cook in the oven along with the pasta. You can substitute with boneless skinless chicken thighs if you prefer the dark meat.
  • Penne pasta: just toss the dry pasta right into the dish — it will cook inside the dish in the oven!
  • Sour cream: for a richer, creamier sauce. Make sure that your sour cream is at room temperature.
  • Mozzarella cheese: grated mozzarella is a nice finishing touch on top of the casserole. You can use just about any other cheese that you like, too. For instance, try grated cheddar cheese, Monterey Jack, Colby, or Pepper Jack.
  • Grated Parmesan cheese and chopped fresh parsley: optional garnishes for the finished dish!

How to Make Chicken Casserole with Cream of Mushroom Soup

This dump-and-bake chicken mushroom casserole makes weeknight dinners quick and easy!

  1. Whisk together the chicken broth, condensed soup, milk, thyme, salt, garlic powder, and pepper to make the creamy sauce.
  2. Add the uncooked penne pasta, the uncooked chicken, and the sliced mushrooms. This looks like a lot of liquid, but the pasta will absorb most of the sauce while the casserole bakes.
  3. Transfer the mixture to a greased 8-inch square baking dish; cover tightly with aluminum foil.
  4. Bake the casserole, covered, in a 425°F oven for 35-40 minutes, until the pasta is almost tender.
  5. Remove the foil and give everything a good stir in the dish.
  6. Stir in the sour cream, and sprinkle the mozzarella on top.
  7. Return the dish to the oven and bake, uncovered, for 5 more minutes, until the pasta is tender, the chicken is cooked through, and the cheese is melted.
  8. Let the dish stand for about 5 minutes before serving.
  9. Garnish with grated Parmesan cheese and chopped fresh parsley, then enjoy!

Make Ahead

You can assemble the casserole in advance, cover tightly, and freeze before baking or refrigerate for up to 24 hours. Thaw in the refrigerator overnight before proceeding with baking instructions.

Storage

Leftovers will keep in an airtight container in the fridge for 3-4 days or in the freezer for up to 3 months; however, the casserole may dry out as it sits. To reheat, cover the dish with foil and warm in a 350°F oven just until warmed through, about 20 minutes. You can also reheat individual servings in the microwave for about 1 minute, or just until heated through.

Chicken Casserole Recipe Variations

  • Have leftover cooked chicken on hand? You can use the cooked chicken in lieu of the raw chicken, if you prefer. Stir the cooked chicken into the casserole at the same time as the sour cream towards the end of the cooking time.
  • I use Campbell’s Healthy Request Cream of Mushroom Soup, but you can substitute with an organic condensed soup or with another flavor of condensed soup (such as Cream of Celery soup or Cream of Chicken Soup).
  • Swap out the chicken breast and use diced chicken thighs instead.
  • If you’d like to add onions to the casserole, I recommend sauteing them in a lareg skillet with butter before adding them to the casserole. This way you’ll know that they’re soft in the finished dish, rather than biting into a crunchy onion.
  • Season the sauce with additional herbs and spices that you enjoy. Good options include onion powder, rosemary, basil, parsley, oregano, and chives.
  • If using a different shape of pasta, look for a variety that has a similar suggested cooking time on the box (about 11-12 minutes) — otherwise you’ll need to adjust the casserole’s baking time in the oven.
  • Add a splash of dry sherry to the sauce for even more flavor.

Tips for the Best Chicken Mushroom Casserole Recipe

  • Make sure that the sour cream is at room temperature (not too cold) when you stir it into the dish. This will ensure that the sour cream blends smoothly into the sauce and doesn’t “break” or separate when it hits the hot casserole.
  • Total cooking time will varydepending on the type of pan that you use and on your individual oven. A glass or ceramic casserole dish will take longer than metal pans, for instance. To know when your casserole is done, taste a bite of the pasta. The noodles should be tender and most of the liquid should be absorbed.
  • Be careful not to overbakethe casserole or the pasta will become mushy.
  • Garnish the finished dish with grated Parmesan cheese and fresh herbs (such as parsley or fresh thyme) for an added layer of flavor.
