Hash browns casserole is a classic comfort food that’s crispy, creamy, and cheesy all at once. It usually features shredded hash browns mixed with sour cream, cheese, and a crunchy topping that bakes up golden and delicious. The simple ingredients come together to make a dish that’s warm and satisfying, perfect for family dinners or holiday breakfasts.
I love making hash browns casserole because it’s so forgiving—you can easily add bits of bacon, sautéed onions, or even some veggies to make it your own. One of my favorite tricks is to use a mix of sharp cheddar and mozzarella for extra gooey, melty cheese that everyone enjoys. It’s the kind of recipe that feels like a big, cozy hug in casserole form.
When I serve hash browns casserole, I like to pair it with a fresh green salad or maybe some scrambled eggs on the side to round out the meal. It’s also a great dish to bring to potlucks or brunch gatherings because it travels well and cooks all in one dish. Plus, leftovers taste just as good, which is always a win in my book!
Key Ingredients & Substitutions
Hash browns: Frozen shredded hash browns work great here—they give just the right texture. If fresh potatoes are your thing, grate and dry them well to avoid a soggy casserole.
Sour cream: Adds creaminess and tang. Greek yogurt is a nice substitute for a lighter version with similar texture.
Cream of chicken soup: This creates the creamy base. For a vegetarian option, use cream of mushroom or a homemade white sauce.
Cheddar cheese: Sharp cheddar gives the casserole its cheesy kick. You can mix in mozzarella or Monterey Jack for extra meltiness.
Bacon: Adds smoky flavor and crunch. For a vegetarian dish, omit or replace with sautéed mushrooms or smoked paprika for depth.
How Do You Get a Crispy, Golden Topping Without Burning?
The topping is what makes this casserole special. The trick is layering cheese and drizzling melted butter on top. Butter helps the cheese and edges crisp just right without burning.
- Spread half the cheese inside the mix, then save half for the top.
- After spreading the cheese on top, drizzle melted butter evenly—this browns the cheese nicely.
- Bake uncovered so moisture escapes, letting the surface crisp up.
- If the top browns too fast, tent loosely with foil during the last 10 minutes.
Also, adding bacon at the end keeps it crunchy and prevents it from drying out or burning during the long bake time.
Equipment You’ll Need
- 9×13 inch baking dish – perfect size for even cooking and easy serving.
- Large mixing bowl – for combining all your ingredients smoothly without spills.
- Measuring cups and spoons – to keep your ingredient amounts just right.
- Spatula or large spoon – to mix everything well and spread the casserole evenly.
- Oven mitts – essential for safely handling the hot baking dish afterward.
Flavor Variations & Add-Ins
- Add cooked sausage instead of bacon for a savory twist and extra protein.
- Mix in chopped bell peppers or green onions for a pop of color and freshness.
- Use Monterey Jack or mozzarella cheese for a creamier, milder flavor.
- Stir in a teaspoon of smoked paprika or chili powder to give the casserole a smoky, subtle heat.
Classic Cheesy Hash Browns Casserole
Ingredients You’ll Need:
- 1 (30 oz) package frozen shredded hash browns, thawed
- 1 cup sour cream
- 1 can (10.5 oz) cream of chicken soup
- 2 cups shredded sharp cheddar cheese, divided
- ½ cup chopped onion (optional)

How Much Time Will You Need?
This casserole takes about 15 minutes to prepare and 45 to 60 minutes to bake. You’ll spend some time mixing the ingredients and assembling the casserole, then just pop it in the oven and wait for it to turn golden and bubbly. After baking, let it rest for 5 minutes before serving.
Step-by-Step Instructions:
1. Prepare the Dish and Mix Ingredients:
Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking dish with butter or nonstick spray. In a large bowl, mix the thawed hash browns, sour cream, cream of chicken soup, 1 ½ cups cheddar cheese, chopped onion (if using), garlic powder, salt, and pepper until everything is well blended.
2. Assemble the Casserole:
Spread the hash brown mixture evenly into the prepared baking dish, pressing down gently. Sprinkle the remaining ½ cup cheddar cheese evenly over the top, then drizzle melted butter over it all.
3. Bake and Finish:
Bake uncovered for 45 to 60 minutes until the casserole is bubbly and golden brown on top. If you’re using bacon, sprinkle the crumbled bacon over the top during the last 10 minutes of baking to keep it crisp and warm. Once done, let it cool for 5 minutes and garnish with fresh parsley before serving.
Can I Use Fresh Potatoes Instead of Frozen Hash Browns?
Yes, you can! Just grate the potatoes and squeeze out as much moisture as possible using a clean kitchen towel to prevent a soggy casserole.
Can I Make This Casserole Ahead of Time?
Absolutely! Prepare the casserole up to the baking step, cover it tightly with foil, and refrigerate for up to 24 hours. Bake it a little longer if baking straight from the fridge.
How Should I Store Leftovers?
Store leftover casserole in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F until warmed through for best texture.
Can I Substitute Cream of Chicken Soup?
Yes! Use cream of mushroom or cream of celery soup as alternatives, or make a quick homemade white sauce if you prefer a fresher taste.
