Potato Chicken Broccoli Casserole (Printable)

Comforting baked casserole combining tender chicken, potatoes, and broccoli in creamy cheddar sauce.

# What You'll Need:

→ Meats

01 - 2 cups cooked chicken breast, cubed or shredded

→ Vegetables

02 - 4 medium russet potatoes, peeled and diced
03 - 2 cups broccoli florets, chopped
04 - 1 small onion, finely chopped
05 - 2 cloves garlic, minced

→ Dairy & Eggs

06 - 1 cup sour cream
07 - 1 cup shredded cheddar cheese (plus ½ cup for topping)
08 - ½ cup milk
09 - 2 tablespoons unsalted butter

→ Pantry & Seasonings

10 - 1 teaspoon salt
11 - ½ teaspoon black pepper
12 - ½ teaspoon paprika
13 - ½ teaspoon dried thyme

# Directions:

01 - Preheat your oven to 400°F (200°C). Lightly grease a 9x13-inch baking dish with cooking spray or butter.
02 - Bring salted water to a boil in a large pot. Add diced potatoes and cook for 8–10 minutes until just fork-tender. Drain thoroughly and set aside.
03 - Steam broccoli florets for 3–4 minutes until bright green and slightly tender. Do not overcook.
04 - In a large mixing bowl, combine cooked potatoes, steamed broccoli, chicken, onion, and garlic. Mix gently to distribute evenly.
05 - In a separate bowl, whisk together sour cream, milk, melted butter, 1 cup cheddar cheese, salt, pepper, paprika, and dried thyme until completely smooth and creamy.
06 - Pour the creamy sauce mixture over the potato, chicken, and broccoli mixture. Stir gently with a spatula to coat everything evenly without mashing the potatoes.
07 - Transfer the mixture to the prepared baking dish, spreading it into an even layer. Sprinkle the remaining ½ cup cheddar cheese evenly across the top.
08 - Bake uncovered for 25–30 minutes until the casserole is bubbly around the edges and the cheese topping is golden brown.
09 - Let the casserole rest for 5 minutes before serving to allow the sauce to set slightly for easier scooping.

# Cooking Tips:

01 -
  • Everything bakes in one dish so cleanup is practically nonexistent
  • The creamy sauce gets into every nook and cranny of the potatoes
  • It reheats beautifully for tomorrows lunch
  • My kids actually ask for broccoli when its in this casserole
02 -
  • Dont skip par-cooking the potatoes or theyll still be crunchy when the cheese is burning
  • Overcooking the broccoli before baking makes it mushy so watch closely
  • The sauce thickens as it bakes so it might look too thin going into the oven
  • Letting it rest is crucial or it will be too runny when you serve it
03 -
  • Cut all vegetables and chicken to similar sizes for even cooking
  • Grate your own cheese instead of buying pre-shredded for better melting
  • Use a glass baking dish so you can see when the bottom is bubbling
