Step 1: Preheat Your Oven
Set your oven to 400°F (200°C) and lightly grease a 9×13-inch baking dish.
Step 2: Mix the Casserole Base
In a large mixing bowl, combine the thawed hashbrowns, shredded chicken, cream of chicken soup, cream of mushroom soup, sour cream, milk, and melted butter. Stir until the mixture is creamy and well blended.
Next, add the chopped onions, garlic powder, salt, pepper, and 1 cup of the shredded cheddar cheese. Mix everything until it’s evenly incorporated.
Step 3: Assemble the Casserole
Pour the mixture into your prepared baking dish and spread it evenly. Sprinkle the remaining ½ cup of cheddar cheese over the top. For extra texture and crunch, scatter breadcrumbs or crushed cornflakes over the cheese layer (optional but recommended!).
Step 4: Bake to Perfection
Place the casserole in the preheated oven and bake uncovered for 45 to 50 minutes, or until the top is golden and the edges are bubbling.
Step 5: Let It Rest & Serve
Remove the casserole from the oven and let it rest for 5–10 minutes before serving. Garnish with fresh parsley if desired.
