🛒 Ingredients
- 1 bag (30 oz / approx. 850g) frozen shredded hashbrowns, thawed
- 3 cups cooked chicken, shredded or diced (rotisserie chicken works perfectly!)
- 1 can (10.5 oz / 298g) condensed cream of chicken soup (or cream of mushroom)
- 1 cup sour cream
- ½ cup (115g) unsalted butter, melted
- 1 small yellow onion, finely diced
- 1 tsp garlic powder
- 1 tsp onion powder
- 2 ½ cups shredded Cheddar or Colby Jack cheese, divided
- Fresh parsley, chopped (for garnish)
- Salt and freshly cracked black pepper, to taste
👩🍳 Step-by-Step Instructions
Step 1: Prep the Oven and Pan
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with non-stick cooking spray or butter and set it aside.
Step 2: Whisk the Creamy Base
In a very large mixing bowl, combine the melted butter, cream of chicken soup, sour cream, diced onion, garlic powder, onion powder, salt, and black pepper. Whisk everything together until the mixture is completely smooth and well combined.
Step 3: Fold in the Fillings
Add the shredded chicken, thawed hashbrowns, and 1 ½ cups of the shredded cheese into the bowl with the cream sauce. Using a large spatula, gently fold the ingredients together until the chicken and potatoes are completely coated in the sauce.
Step 4: Layer and Bake
Spread the mixture evenly into your prepared 9×13-inch baking dish, smoothing down the top. Bake uncovered for 35 to 40 minutes until the casserole is hot and bubbling around the edges.
Step 5: The Ultimate Cheese Blanket
Remove the casserole from the oven and scatter the remaining 1 cup of shredded cheese evenly across the top. Return it to the oven for an additional 5 to 8 minutes, or switch to Broil for the last 2 minutes, keeping a close eye on it. You want the top to be deeply golden-brown, bubbly, and beautifully speckled with toasted cheese spots.
Let it cool for about 5 to 10 minutes to set slightly, garnish with fresh chopped parsley, slice into squares, and serve!
💡 Quick Variations to Try
- Add a Crunchy Topping: Toss 1 cup of crushed cornflakes or crushed Ritz crackers with 2 tablespoons of melted butter and scatter them over the cheese during the final minutes of baking for an incredible texture contrast.
- Make it Loaded: Stir in ½ cup of crispy crumbled bacon bits and some chopped green onions directly into the hashbrown mixture before baking.
