Ingredients Section
- 2 large chicken breasts: Ensure they are fresh; they are the protein star of this dish!
- 1 head of broccoli: Go for a fresh head rather than frozen for optimal texture—trust me, it makes a difference.
- 4 large potatoes: Russet potatoes are the best choice here for their fluffiness when baked.
- 1 cup shredded cheddar cheese: Opt for sharp cheddar for a flavor punch!
- 1 cup milk: Full-fat milk gives the creamiest sauce.
- 1/2 cup sour cream: Creamy, tangy goodness that melds beautifully into the dish.
- 2 tablespoons butter: Use unsalted butter for better control over seasoning.
- 2 tablespoons flour: Dusting the butter with flour creates a luxurious roux for a thick sauce.
- 1 teaspoon garlic powder: A must for that aromatic garlic flavor—no one ever complains about garlic!
- 1 teaspoon onion powder: Adds depth without overpowering the dish.
- Salt and pepper to taste: Essential for elevating flavors—do not skip this.
Prep Notes: Make sure your butter is at room temperature to ensure even melting when making your roux.
Brand Recommendations: I love using Tillamook cheese for its rich flavor, and for chicken, Foster Farms is always a reliable choice for high quality.

Step-by-Step Instructions
Preheat the oven to 375°F (190°C). This ensures that your casserole bakes evenly throughout.
Wash and peel the potatoes and cut them into 1-inch cubes. This helps them cook evenly in the casserole.
Cut the broccoli into small florets. You want them bite-sized, so they blend well with other ingredients.
Boil the broccoli in a pot of water for about 3-4 minutes until slightly tender. This quick blanching will help keep its vibrant color and crispness. Drain and set aside.
Cook the chicken: In a large skillet over medium heat, cook the chicken breasts until no longer pink in the center (about 7-10 minutes). When they’re done, remove from heat and let cool before cutting into bite-sized pieces.
Make the roux: In the same skillet, melt the butter over medium heat. Then, add the flour, whisking constantly for about 1 minute until it bubbles. This is where you develop that nutty flavor.
Whisk in the milk slowly, stirring until the mixture thickens. You’ll know it’s thick enough when it coats the back of a spoon.
Add seasonings: Stir in the garlic powder, onion powder, salt, and pepper. This is where the flavors really start to shine!
Finish the sauce: Remove from heat and whisk in the sour cream until everything is creamy and well combined.
Layer the ingredients: In a greased baking dish, layer half of the potatoes, followed by half of the broccoli, and half of the chicken.
Pour half of the sauce evenly over the initial layers. Repeat the layering with the remaining potatoes, broccoli, chicken, and sauce in the same order.
Cover with foil: Seal with aluminum foil and bake for 1 hour. This keeps the moisture in, creating a beautifully baked dish.
Cheesy goodness: After 1 hour, remove the foil, sprinkle shredded cheddar cheese over the top, and bake an additional 15-20 minutes until the cheese is melted and bubbly.
Cool and serve: Let the casserole cool for a few minutes before serving. Cut into squares and dig in!
