We’ve been on a casserole kick lately, and I have so many delicious casserole recipes to share with you in the coming months! I recently shared this Hamburger Casserole, which became an instant favorite. I’m excited to add this creamy chicken casserole to our collection of comfort food recipes!

This chicken casserole features chicken, vegetables and cheese tossed together in a creamy sauce. I opted to use potatoes instead of noodles or rice in this recipe, because we just love the comforting combination of chicken and potatoes. (See our Crockpot Chicken and Potatoes for another scrumptious example.) Instead of relying on a can of cream soup, this homemade casserole is made completely from scratch. The cream sauce comes together so easily, and tastes so much better since it’s made from scratch.

Why You’ll Love this Recipe

  • Comfort Food: Between the chicken, potatoes, cheese and crispy topping, there’s so much to love about this hearty casserole. Since it’s made with wholesome ingredients, it’s a casserole that you can feel good about eating.
  • Homemade: This flavorful casserole is made completely from scratch. While this takes a bit more effort, overall the recipe is straightforward and easy.
  • Delicious Leftovers: I love casseroles because they can feed a crowd, or leave us with tasty leftovers for lunch or dinner.

Recipe Ingredients

Ingredients for chicken casserole recipe.

Here’s an overview of the ingredients you’ll need, plus substitution options.

  • Potatoes: I like to use Yukon gold potatoes because they have a rich, creamy texture and hold their shape well in the casserole. Gold potatoes are also my favorite for Potato Soup. If you only have russets on hand, they’ll work too.
  • Butter & Olive Oil: You’ll sauté the vegetables in butter and olive oil, and these fats also provide the base for the creamy sauce. The butter adds richness while the olive oil lightens things up.
  • Onion & Carrots: Chop the carrots up small so that they soften quickly. If you’re short on time, you can substitute 2 cups of frozen mixed vegetables for the fresh carrots and frozen peas. Add them when the recipe calls for adding the frozen peas.
  • Garlic: You can’t beat the flavor of fresh garlic!
  • Flour: To thicken the sauce.
  • Chicken Broth & Milk: A combination of low sodium chicken broth and whole milk makes a creamy sauce that’s not too rich or heavy.
  • Italian Seasoning, Salt & Pepper: These simple seasonings bring lots of flavor.
  • Cooked Chicken: You can use chopped or shredded cooked chicken breast or shredded rotisserie chicken. See below for my tips on how to cook the chicken if you’re not using rotisserie.
  • Frozen Peas: An easy way to add a green vegetable. No need to thaw them before using.
  • Cheddar Cheese: I recommend sharp cheddar cheese for maximum flavor. It’s best to buy a block of cheddar and shred it yourself. Store bought shredded cheese is often coated with an anti-caking agent that keeps it from melting smoothly.
  • Breadcrumb Topping: Instead of the crushed Ritz cracker topping found in some chicken casserole recipes, we’re using a simple mixture of Panko breadcrumbs, Parmesan cheese, paprika and melted butter. Regular breadcrumbs may be substituted for the Panko, although they won’t be quite as crispy.

Want to use other vegetables? Try mushrooms, bell peppers, celery, cauliflower or spinach.

How to Cook Chicken for a Casserole

I like to use a store-bought rotisserie chicken to make preparing this chicken casserole especially easy. Other options for cooking the chicken include:

How to Make Chicken Casserole

There are a few steps to making this casserole, but each of them is easy. You can get a head start on the prep by chopping the onion and carrots and shredding the cheese ahead of time.

  1. Microwave the potatoes to start softening them up before adding them to the skillet. They won’t soften enough without a little pre-cooking.
  2. Sauté the onion, carrots and potatoes in a large skillet, until tender. Chopped potatoes, carrots and onion in skillet.
  3. Add the garlic and flour and cook for 30 seconds.
  4. Stir in the chicken broth, milk and seasonings. Stir and cook until the sauce thickens, 3-4 minutes. Vegetables and sauce in skillet after thickening.
  5. Stir in the cooked chicken, frozen peas and shredded cheddar. Shredded chicken, cheddar and peas added to skillet.
  6. Transfer the contents of the skillet to a greased baking dish. Casserole filling in baking dish.
  7. Stir together the topping ingredients and sprinkle the topping over the casserole.
  8. Cover with foil and bake at 350° F for 25 minutes. Then uncover and bake for 10 more minutes, until the casserole is hot and bubbly and the topping is golden brown.
