Prep Notes: Ensure your butter is at room temperature for easy mixing. Gather all your ingredients beforehand to streamline the cooking process.

Step-by-Step Instructions
Preheat the Oven: Start by preheating your oven to 375°F (190°C). This is the perfect temperature for baking your casserole to golden perfection!
Prepare Potatoes: Wash and peel the potatoes, then cut them into 1-inch cubes. The smaller the cubes, the faster they cook.
Chop the Broccoli: Cut the broccoli into small florets—think bite-sized pieces!
Blanch the Broccoli: Boil the broccoli in a pot of water for about 3-4 minutes until slightly tender. Drain and set aside; we want them bright green but not mushy.
Cook the Chicken: In a large skillet, cook the chicken breasts over medium heat until they are no longer pink in the center, about 6-8 minutes per side depending on thickness. Remove from heat and let them cool before cutting into bite-sized pieces.
Make the Roux: In the same skillet, melt the butter over medium heat. Once melted, add the flour and whisk constantly for about 1 minute to create a roux.
Add Milk: Slowly whisk in the milk until the mixture thickens, about 2-3 minutes. This is where the creaminess comes to life!
Season Up: Stir in the garlic powder, onion powder, salt, and pepper, then remove from heat. Whisk in the sour cream until everything is well combined.
Layering Time: In a greased 9×13-inch baking dish, layer half of the potatoes, half of the broccoli, and half of the chicken. Pour half of the sauce evenly over this layer. Repeat with the remaining ingredients.
Bake: Cover the baking dish with aluminum foil and bake for 1 hour. This will help everything meld together beautifully.
Add Cheese: After an hour, remove the foil, sprinkle the shredded cheddar cheese on top, and bake for an additional 15-20 minutes until the cheese is melted and bubbly.
Serve: Let the casserole cool for a few minutes before serving. Enjoy your cozy Baked Potato Chicken and Broccoli Casserole with loved ones around the table!

Expert Tips & Tricks
Stay Fresh: Use the freshest ingredients you can find for the best flavor. Frozen can work in a pinch but avoid mushy veggies.
