How to Make Chicken Hashbrown Casserole Recipe
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This ensures it’s hot and ready for the casserole to bake perfectly and develop a golden crust.
Step 2: Combine Hashbrowns and Chicken
In a large mixing bowl, toss together the shredded hashbrowns and shredded cooked chicken breast. This first layer mixes the base and the main protein beautifully.
Step 3: Add Cheddar Cheese
Next, fold in the shredded cheddar cheese. It will melt into the mixture and create a creamy, cheesy texture that enhances every bite of your Chicken Hashbrown Casserole Recipe.
Step 4: Mix in Sour Cream, Milk, and Butter
Add sour cream, milk, and the melted butter to the bowl. These ingredients are what bring moisture and richness to the casserole, making it irresistibly creamy and smooth.
Step 5: Season the Mixture
Sprinkle in garlic powder, onion powder, black pepper, and salt. These seasonings boost the overall flavor profile, adding savory depth without overpowering the natural taste of the chicken and potatoes.
Step 6: Thoroughly Combine All Ingredients
Mix everything together until you see the ingredients are evenly combined. This ensures every slice you serve has a perfect balance of all flavors and textures.
Step 7: Fold in Green Onions
Gently stir in the chopped green onions for a pop of color and a mild fresh onion flavor that brightens the casserole beautifully.
Step 8: Transfer to Baking Dish
Spread your mixture evenly into a greased 9×13-inch baking dish. Making sure it’s level helps the casserole bake uniformly.
Step 9: Prepare the Breadcrumb Topping
In a small bowl, mix the breadcrumbs with a tablespoon of melted butter. This small step is the secret to achieving that perfect, crispy topping everyone will love.
Step 10: Add the Topping
Sprinkle the breadcrumb mixture evenly over the surface of your casserole. This golden layer will add irresistible crunch and contrast to the creamy interior.
Step 11: Bake Until Golden and Bubbly
Place the dish in your preheated oven and bake for 30 to 35 minutes. You’ll know it’s ready when the top turns golden brown and you see bubbling around the edges.
Step 12: Cool Before Serving
Remove your casserole from the oven and let it rest for a few minutes. This pause helps the ingredients set so that each serving holds together nicely.
Step 13: Serve and Enjoy
Dish out warm plates and savor the comfort and joy packed into every bite of your Chicken Hashbrown Casserole Recipe.

FAQs
Can I use fresh potatoes instead of shredded hashbrowns?
While fresh potatoes can work, shredded hashbrowns save time and provide a better texture due to their consistent shredding and moisture content. Fresh potatoes would require pre-cooking and could affect the creaminess.
Is it possible to make this recipe vegetarian?
Absolutely! Simply omit the chicken and consider adding in vegetables like mushrooms, bell peppers, or spinach to keep the dish hearty and flavorful without the meat.
Can I prepare this casserole ahead of time before baking?
Yes, you can assemble the casserole the day before. Just cover it and keep it refrigerated until you’re ready to bake. This makes it a convenient option for busy days or gatherings.
What cheese works best for this casserole?
Cheddar cheese is classic for its sharp flavor and melting quality, but you can mix it up with Monterey Jack, Colby, or even a blend of cheeses depending on your preference.
How do I get a really crispy topping?
Make sure you mix the breadcrumbs with melted butter before sprinkling. This helps the crumbs brown evenly and become delightfully crisp when baked.
