Ingredients Needed

  • Chicken – Cooked chicken breasts, diced
  • Broccoli – florets are best, frozen or fresh steamed
  • Potatoes – Russet potatoes, peeled and diced small
  • Mayonnaise – Duke’s is my favorite brand! Don’t use Miracle Whip.
  • Cheese – Shredded cheddar is best but you can use a Mexican blend, or Jack, sharp cheddar, or even mozzarella.
  • Milk – Use what you have on hand
  • Condensed soup – Cream of chicken soup is the best compliment but you can use cheddar cheese soup or even cream of mushroom.
  • Ritz crackers or Cornflakes for the topping
  • Spices – Onion powder, paprika, garlic powder, salt and pepper to season
  • Butter – Unsalted is best for this recipe to control the salt levels.

Storage

Leftovers: Leftovers will keep about 3 to 4 days in the refrigerator in an air tight container.

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

Freeze: When freezing chicken broccoli potato casserole, then make sure it is sealed tightly to avoid freezer burn. Freeze for 2 months. Thaw overnight before reheating.

Substitutions

  • Broccoli – If you really prefer not using broccoli, then there are plenty of alternatives. Cabbage, cauliflower, and kale all work well.
  • Potatoes – Lets face it, potatoes are amazing, but sometimes you just need a change. In that case, there are other root veggies that work too, like turnips or rutabagas.
  • Mayo – If mayo isn’t desired, then there are many other ways to go. Substitute Greek yogurt or sour cream.
  • Topping – Don’t have cornflakes or Ritz crackers handy? Then Saltines work too, or use panko style bread crumbs. You can also make your own bread crumbs by toasting bread, then pulsing it lightly in a grinder. If it clumps, then toast it a bit more.

Best Casserole Tips

  • Lightly coat your casserole dish with olive oil cooking spray.
  • Cut your broccoli florets to a similar size so they cook evenly.
  • Same with the chicken cubes. The more evenly sized they are, the better.
  • 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!

Prep Time 5 minutes

Total Time 35 minutes

Ingredients

  • 2 cups cooked chicken, chunked or diced

  • 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

Instructions

  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.

Notes

  • 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.
