Perfect for feeding a crowd or meal-prepping for the week, this casserole is a beloved classic in American kitchens. It’s hearty, wholesome, and packed with texture: soft baked potatoes, juicy chicken, tender broccoli, and a golden, cheesy crust.
Whether you’re looking for a simple weeknight bake, something cozy for chilly nights, or a dish that doubles as leftovers, this casserole checks all the boxes.
Ingredients Overview
Each ingredient plays a key role in achieving the right texture and flavor. Let’s walk through what you’ll need and possible variations.
Potatoes
-
Russet potatoes are ideal for their fluffy texture after baking.
-
Yukon Gold offers a creamier bite and rich, buttery flavor.
-
For speed, you can use pre-cooked or leftover baked potatoes—simply dice and toss them in.
Chicken
-
Boneless, skinless chicken breast or thighs both work. Thighs add more moisture and flavor.
-
Use rotisserie chicken for a shortcut or if you’re low on time.
-
Dice into bite-sized pieces for even cooking and easy serving.
Broccoli
-
Fresh broccoli florets are best for texture.
-
If using frozen, thaw and pat dry to avoid watering down the casserole.
-
Cut into small, bite-sized pieces so they cook quickly and evenly.
Cheese
-
Cheddar cheese is the classic choice—sharp or mild depending on your taste.
-
Blend with Monterey Jack or mozzarella for a meltier finish.
-
Reserve a handful for topping before baking to get that golden crust.
Sauce Base
-
A mixture of sour cream, milk, and cream cheese creates a rich, tangy base that mimics baked potato toppings.
-
You can also add a bit of mayonnaise or Greek yogurt for creaminess.
Seasonings
-
Simple spices like garlic powder, onion powder, salt, pepper, and paprika elevate the flavor without overpowering.
-
A dash of dried parsley or thyme adds a herby touch.
Toppings (Optional)
-
Chopped bacon, green onions, or even crushed Ritz crackers can be sprinkled on top for added texture and flavor.
Step-by-Step Instructions
Creating this casserole is straightforward, but there are a few key steps to make it exceptional.
-
Bake or Parboil the Potatoes
If starting from raw, dice potatoes into 1-inch cubes and parboil them in salted water for 8–10 minutes until just fork-tender.
Alternatively, use leftover baked potatoes and simply cube them. -
Cook the Chicken
In a skillet, sauté diced chicken with a bit of olive oil, salt, pepper, and garlic powder. Cook for 6–8 minutes until browned and cooked through. Set aside. -
Blanch the Broccoli
Bring a small pot of water to a boil. Blanch broccoli florets for 1–2 minutes, then immediately plunge into ice water to retain their green color and texture. -
Make the Sauce
In a large mixing bowl, combine sour cream, softened cream cheese, milk, shredded cheese (reserve some for topping), and seasonings. Stir until smooth and creamy. -
Assemble the Casserole
In a greased 9×13-inch baking dish, combine the potatoes, cooked chicken, and broccoli. Pour the sauce over and toss everything together until evenly coated. -
Top with Cheese and Bake
Sprinkle reserved cheese over the top. If using bacon or breadcrumbs, add them now.
Bake uncovered at 375°F (190°C) for 25–30 minutes, until the cheese is melted and bubbling. -
Cool Slightly and Serve
Let the casserole rest for 5–10 minutes before serving to set and develop flavor.
