Chicken Potato Broccoli Casserole

This classic casserole recipe has everything going for it. The cheesy chicken and broccoli, soft potatoes, the crunchy topping, and rich sour cream sauciness. You just can’t go wrong with it.

Even better, it is simple to make and easy to do ahead of time which makes it great for busy weeknights. And the perfect way to use up leftover chicken from the grill.

Serve it for brunch, lunch, or dinner. The whole family will love it and it makes even better leftovers. It reminds me of the perfect loaded baked potato. Only better!

ingredients for simple dinner of chicken casserole

Ingredients Needed

  • Chicken – Cooked chicken breasts. Substitute rotisserie chicken for easier prep.
  • Broccoli – I prefer the florets but feel free to use your favorite pieces.
  • Potatoes – Russet potatoes work best or substitute red potatoes.
  • Mayonnaise – Duke’s is my favorite brand! Don’t use Miracle Whip.
  • Cheese – Shredded cheddar cheese is best or sub a Mexican, Monterey Jack, sharp cheddar, or even mozzarella.
  • Condensed soup – Cream of chicken soup or substitute cream of mushroom or cream of onion.
  • Spices – Onion powder, paprika, garlic powder. Substitute Italian seasoning or ranch seasoning if desired.
  • Ritz crackers or Cornflakes for the topping. Substitute Saltines or panko breadcrumbs.
  • Pantry staples – Unsalted butter, milk, salt, black pepper.

  3. Combine the mayo, milk, condensed soup, seasonings and a cup of the cheese.
  1. Pour over the potatoes and spread to cover them. Top with remaining shredded cheese.

How long does it last?

This casserole will last 3-4 days in the refrigerator in an airtight container.

Reheat in the oven at 325 degrees for 15 minutes or until heated through. If you reheat in the microwave, on medium high for 1-2 minutes or until the center is hot.

Can I freeze it?

Yes, you can! Bake and cool completely. Store in the baking dish if it is freezer safe or transfer to a freezer safe container and freeze for up to 3 months.

Thaw overnight in the refrigerator before reheating.

Tips for the Best Casserole

  • Lightly coat your casserole dish with olive oil cooking spray so it doesn’t stick.
  • Cut your potatoes, broccoli florets, and chicken into similar size pieces for easier cooking.
  • Don’t use raw chicken. Use a rotisserie chicken or leftover cooked and shredded chicken.
  • Substitute chicken thighs if desired.
  • Let the casserole cool briefly first before you bring it to the table if you plan on serving it from the casserole dish at the table.
  • Any type of cream condensed soup works so feel free to mix it up if you like.
  • Top with a combination of bacon and cheese to make it over the top!

  • 2 cups cooked chicken chunked or diced
  • 12 ounces frozen broccoli florets lightly steamed
  • 2 pounds diced potatoes
  • ½ cup mayonnaise
  • ½ cup milk
  • 1 10.5 ounce can cream of chicken soup
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • ½ teaspoon paprika
  • ½ teaspoon black pepper
  • 1 teaspoon salt
  • 2 cups shredded cheddar cheese
  • 2 tablespoons butter melted
  • 1 cup crushed cornflakes or ritz crackers


  • Preheat oven to 350F. Spray the 9×13 baking dish with nonstick spray.
  • Spread the broccoli in the bottom of the dish.
  • Top with diced chicken and final the potatoes.
  • In a separate bowl, combine the mayo, milk, soup, and seasonings. Mix in 1 cup of the shredded cheese.
  • Pour over the potatoes and spread to cover.
  • Top with remaining shredded cheese.
  • Mix the melted butter and corn flakes.
  • Sprinkle over the top of the cheese.
  • Bake covered for 20 minutes.
  • Uncover and bake for 10 more to get the topping golden brown.
  • When brown and bubbly, remove from the oven and serve.


  • If the florets are large you might need to steam them. If they are small you can skip that step. Frozen florets will be tender.
  • I use the frozen “southern style”diced potatoes but you can also find diced potatoes in the refrigerated section – If not then 2 pounds diced but boiled/cooked
  • You can easily make this ahead of time and freeze for later.
  • Substitute pork or turkey for the chicken.
  • Cauliflower works as a delicious substitute for the broccoli.
  • Panko crumbs also work for the crunchy topping instead of the cereal or crackers.
