Step 3: Add Chicken and Hashbrowns
Fold in the shredded chicken, thawed hashbrowns, and chopped onion. Stir until everything is evenly coated with the creamy mixture. Half of the cheddar cheese can also be mixed in at this stage for a rich, cheesy layer throughout the casserole.
Step 4: Transfer to Baking Dish
Grease a 9×13-inch casserole dish with butter or non-stick spray. Pour the mixture into the dish, spreading it evenly with a spatula.
Step 5: Add Toppings
Sprinkle the remaining cheddar cheese over the top. If you like a crispy topping, mix crushed cornflakes with melted butter and sprinkle it over the cheese for a delightful crunch.
Step 6: Bake to Perfection
Place the casserole in the preheated oven and bake for 45-50 minutes, or until the top is golden brown and the casserole is bubbling. Check the center to ensure the hashbrowns are tender and the chicken is heated through.
Step 7: Let It Rest
Remove the casserole from the oven and let it rest for 5-10 minutes before serving. This helps the layers set slightly and makes serving easier.
Step 8: Serve and Enjoy
Scoop generous portions onto plates and enjoy! This casserole pairs beautifully with a simple green salad or steamed vegetables for a complete, comforting meal.
Tips for an Even Better Hashbrown Chicken Casserole
- Use leftover chicken: Rotisserie or baked chicken makes this dish quick and easy.
- Make it ahead: Assemble the casserole the night before and bake it the next day.
- Customize the veggies: Add bell peppers, mushrooms, or peas for added color and nutrition.
- Extra cheesy: For a gooey top, add a little mozzarella or Monterey Jack cheese along with cheddar.
- Crispy topping hack: Mix panko breadcrumbs with melted butter instead of cornflakes for a gourmet crunch.
