How to Make Chicken Potato Broccoli Casserole


Step 1: Preheat & Prepare

  • Preheat oven to 375°F (190°C)
  • Lightly grease a 9×13-inch casserole dish

Step 2: Cook the Potatoes

  • Dice potatoes into small, bite-sized cubes
  • Boil in salted water for 8–10 minutes, until just fork-tender
  • Drain and set aside

Shortcut: Use leftover roasted potatoes or frozen diced potatoes.


Step 3: Blanch the Broccoli

  • Bring a small pot of water to a boil
  • Add broccoli florets and cook for 2–3 minutes, just until bright green
  • Drain and rinse with cold water to stop cooking

Or use frozen broccoli — just thaw and drain excess water.


Step 4: Mix the Base

In a large mixing bowl, combine:

  • Cooked chicken
  • Cooked potatoes
  • Blanched broccoli
  • 1 cup of shredded cheese
  • Sour cream or yogurt
  • Cream of chicken soup
  • Milk
  • Garlic powder, onion powder, salt, and pepper

Mix everything together until well combined.


Step 5: Assemble the Casserole

  • Pour the mixture into the prepared baking dish
  • Spread evenly with a spatula
  • Top with the remaining ½ cup of shredded cheese

Step 6: Optional Crunchy Topping

  • Mix crushed crackers or breadcrumbs with melted butter
  • Sprinkle evenly over the casserole

Step 7: Bake

  • Bake uncovered for 25–30 minutes, until bubbly and golden
  • If using a topping, broil the last 2–3 minutes for extra crispiness
  • Let rest for 5 minutes before serving
