Ingredients Needed

Best Casserole Tips

  • Lightly coat your casserole dish with olive oil cooking spray.
  • Cut your potatoes, broccoli florets, and chicken into similar size pieces for easier cooking.

  • 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.

Chicken Potato Broccoli Casserole

Yield: 9 servings
Prep Time: 5 minutes
Cook Time: 30 minutes
Total Time: 35 minutes

Chicken potato broccoli casserole is a hearty classic casserole dish with a nice crunchy topping.


  • 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


  1. Preheat oven to 350F. Spray the 9x13 baking dish with nonstick spray.
  2. Spread the broccoli in the bottom of the dish.
  3. Top with diced chicken and final the potatoes.
  4. In a separate bowl, combine the mayo, milk, soup, and seasonings. Mix in 1 cup of the shredded cheese.
  5. Pour over the potatoes and spread to cover.
  6. Top with remaining shredded cheese.
  7. Mix the melted butter and corn flakes.
  8. Sprinkle over the top of the cheese.
  9. Bake covered for 20 minutes.
  10. Uncover and bake for 10 more to get the topping golden brown.
  11. 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.
