How to Make Chicken Hashbrown Casserole Recipe
Step 1: Preheat your oven
Start by setting your oven to 375°F (190°C). This temperature is just perfect to cook the casserole evenly, ensuring a golden crust and melty interior.
Step 2: Combine the hashbrowns and chicken
In a large mixing bowl, toss together the shredded hashbrowns and cooked shredded chicken breast. This simple combination forms the hearty base of the casserole, blending crispy potatoes with tender chicken.
Step 3: Add the cheese
Mix in the shredded cheddar cheese. This ingredient is the glue that keeps the casserole rich and cheesy with every bite, melting beautifully when baked.
Step 4: Stir in creams and butter
Next, add the sour cream, milk, and melted butter to the bowl. These ingredients bring that luscious creaminess which makes the casserole delightfully moist without being heavy.
Step 5: Season the mixture
Sprinkle the garlic powder, onion powder, black pepper, and salt over the mixture. Seasoning is key here to elevate all the flavors and create a well-rounded taste profile.
Step 6: Combine everything thoroughly
Mix all ingredients thoroughly to make sure every bit is seasoned and coated evenly. This step ensures a consistent flavor in every spoonful.
Step 7: Fold in green onions
Gently stir in the chopped green onions for a pleasant hit of freshness and color that contrasts with the creamy casserole base.
Step 8: Transfer to baking dish
Spread the mixture evenly in a greased 9×13-inch baking dish. This even layer helps the casserole cook uniformly and develop a perfect crust.
Step 9: Prepare crunchy topping
In a small bowl, mix the breadcrumbs with a tablespoon of melted butter to combine. This buttery breadcrumb blend is the secret to that irresistibly crisp and golden topping.
Step 10: Add breadcrumb topping
Sprinkle the breadcrumb mixture evenly over the spread casserole to create a delicious crust that contrasts beautifully with the creamy interior.
Step 11: Bake until bubbly and golden
Pop the casserole into the preheated oven and bake for 30 to 35 minutes. You’ll know it’s done when the top is golden brown and the casserole is hot and bubbly through the center.
Step 12: Cool before serving
Once out of the oven, let the casserole cool for a few minutes. This resting time helps everything set, making it easier to cut and serve.
Step 13: Serve and enjoy!

FAQs
Can I use frozen hashbrowns for this recipe?
Absolutely! Just make sure to thaw and drain any excess moisture from frozen hashbrowns before mixing them in to avoid a soggy casserole.
What kind of chicken works best?
Cooked chicken breast is ideal for this casserole because it’s lean and shreds nicely, but leftover rotisserie chicken or even shredded turkey would work wonderfully too.
Can I make this recipe gluten-free?
Yes, simply swap the regular breadcrumbs for gluten-free breadcrumbs, and double-check all your seasonings and cheese are gluten-free friendly.
Is there a vegetarian version of this casserole?
You can easily make it vegetarian by omitting the chicken and adding extra veggies like mushrooms, bell peppers, or spinach to keep things hearty.
Why is my casserole watery?
This usually happens if the hashbrowns or chicken hold too much moisture. Make sure to squeeze out any water from thawed hashbrowns and use cooked, well-drained chicken. Also, don’t skip the proper amounts of sour cream and butter, as they help bind everything without excess liquid.
