Frequently Asked Questions
Can I use diced or O’Brien hashbrowns instead of shredded?
Yes, you can use the diced, cubed, or O’Brien style (with peppers and onions) hashbrowns. The texture will be chunkier and a bit heartier. If using O’Brien potatoes, they already have added vegetables, which can add nice flavor. You can still follow the same recipe; no adjustments are needed. Some people prefer the shredded style for a more classic, cohesive casserole, while others love the bite-sized potato pieces. Both work beautifully.
What if I don’t have cream of chicken soup?
You can substitute with an equal amount of cream of mushroom, cream of celery, or even cream of potato soup. The flavor will shift slightly, but it will still be delicious. You can also make a quick homemade version: melt 2 tablespoons of butter, whisk in 2 tablespoons of flour to make a roux, then slowly add 1 cup of chicken broth and ½ cup of milk, cooking until thickened. Season with salt, pepper, and a pinch of poultry seasoning. Use this in place of the canned soup. The casserole will be just as creamy and comforting.
Can I use raw chicken instead of cooked?
It’s safer and more reliable to use cooked chicken in this casserole. Raw chicken would need to be cut very small and baked long enough to reach a safe internal temperature, which could overcook the hashbrowns and dry out the sauce. For the best results, cook the chicken beforehand—poaching, baking, or using a rotisserie chicken are all great options. You can even cook the chicken in a slow cooker or Instant Pot earlier in the day. The casserole itself is designed to heat through and meld flavors, not to cook raw meat from scratch.
Is this casserole gluten-free?
It can be. To make it gluten-free, use a gluten-free cream of chicken soup (or the homemade version with cornstarch instead of flour). The hashbrowns, cheese, sour cream, and chicken are naturally gluten-free. For the crunchy topping, use crushed gluten-free cornflakes, gluten-free panko breadcrumbs, or crushed gluten-free crackers. Always check labels to be sure, especially on the soup and any processed ingredients. The casserole will still be wonderfully creamy and satisfying.
Can I make this in a slow cooker?
Yes, this casserole adapts well to a slow cooker. Assemble the filling (without the topping) in the greased slow cooker insert. Cook on LOW for 4–5 hours or on HIGH for 2–3 hours, until the hashbrowns are tender and the casserole is hot. About 30 minutes before serving, add the crunchy topping and continue cooking on HIGH, uncovered, to let the topping crisp slightly. You can also transfer the cooked casserole to an oven-safe dish, add the topping, and broil for a few minutes for maximum crunch. The slow cooker method is convenient for keeping the casserole warm at a potluck or brunch buffet.

Prep Time:
15 minutes
Cook Time:
40–50 minutes
Rest Time:
10 minutes
Total Time:
1 hour 5 minutes – 1 hour 15 minutes
Servings:
8–10
Ingredients
- 1 bag (30 oz) frozen shredded hashbrowns (do not thaw)
- 2–3 cups cooked, shredded or cubed chicken (rotisserie chicken works great)
- 1 cup full-fat sour cream
- 1 can (10.5 oz) condensed cream of chicken soup, undiluted
- 2 cups shredded sharp cheddar cheese, divided
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- ¼ teaspoon freshly ground black pepper
- Salt to taste (be light-handed; soup and cheese are salty)
For the Crunchy Topping:
- 2 cups crushed cornflakes (or crushed Ritz crackers, or panko breadcrumbs)
- 3–4 tablespoons unsalted butter, melted
- Optional: a sprinkle of paprika, garlic powder, or dried parsley for the topping
Instructions
- Preheat oven to 375°F (190°C). Grease a 9×13-inch baking dish.
- In a large bowl, combine the undiluted cream of chicken soup, sour cream, garlic powder, onion powder, black pepper, and a pinch of salt. Stir until smooth.
- Add the frozen hashbrowns, cooked chicken, and 1½ cups of the shredded cheddar cheese. Fold gently until everything is evenly coated with the sauce. Transfer to the prepared baking dish and spread into an even layer.
- In a small bowl, combine the crushed topping (cornflakes, crackers, or panko) with the melted butter. Toss to coat. Sprinkle the buttery crumbs evenly over the casserole, then top with the remaining ½ cup shredded cheddar cheese.
- Bake, uncovered, for 40–50 minutes, until the topping is deeply golden brown, the edges are bubbly, and the center is hot. If the topping browns too quickly, tent loosely with foil. Optionally, broil for 1–2 minutes at the end for extra crunch.
- Let the casserole rest for 10 minutes before serving. Garnish with fresh parsley or chives if desired. Serve hot.
Notes
- Do not thaw the hashbrowns; add them straight from the freezer. Thawing can release excess moisture and make the casserole watery.
- Rotisserie chicken is a great time-saver. You can also use leftover roasted chicken, poached breasts, or even canned chicken in a pinch.
- Customize the topping with your favorite crunchy element: crushed cornflakes, Ritz crackers, panko, or French fried onions all work wonderfully.
- Store leftovers covered in the refrigerator for up to 4 days, or freeze baked casserole for up to 2 months. Reheat in the oven or microwave, and add fresh topping for extra crunch if desired.
