🥘 Ingredients
Frozen Hashbrowns- You'll need frozen hashbrowns for the base of this recipe. They can be used from frozen and do not need to be thawed.
Sour Cream- You can use sour cream or plain unflavored Greek yogurt. This adds a rich and creamy consistency.
Condensed Mushroom Soup- Casseroles almost always have a condensed soup and we find that cream of mushroom or cream of chicken works best here.
Milk- Use some milk to get the mixture to the correct consistency.
Butter- Adding butter will help us get a richer taste and a nice golden top on the hashbrowns.
Bacon or Ham- This is completely optional because this dish tastes great with or without meat.
Onion- Add in onion as a great way to bring more depth of flavor to the dish.
Shredded Cheese- For a comforting taste we like to add shredded cheese to this casserole. You can use any cheese variety of choice but I prefer cheddar cheese.

🔪 Instructions
Check out how to make this easy hash brown casserole with these simple step-by-step instructions:
Preheat the oven to 350 degrees F and grease the inside of a 9x13 baking dish, set it aside.
In a large mixing bowl combine the hashbrowns, sour cream, onion, cream of mushroom, milk, half of the cheese, and your meat (if using) until well blended.
Pour into your prepared baking dish and then top with the remaining shredded cheese.
Slice the butter into 12 equal sized squares and arrange them onto the cheese in 4 rows of 3.
Cover the pan with foil and bake in the oven for 60 minutes.
Remove the foil and cook for an additional 10-15 minutes.
Allow to cool in the pan for about 5-10 minutes. This will help the casserole to set before serving, making it easier to dish up.
Serve warm.
📖 Variations
You can make this recipe with or without meat. I often use cooked bacon bits or small diced ham when I want to add in meat but even shredded chicken or meatless tastes great.
🧾 Substitutions
Hashbrowns. You can use homemade hashbrowns instead of storebought if desired. This is roughly 4 cups of hashbrowns.
Condensed soup. Cream of mushroom soup can be swapped out for cream of chicken.
Milk. This easy hashbrowns bake can be made with half and half or even heavy cream instead of milk.
🍴 Make Ahead Tips
You can make this easy cheesy hashbrowns casserole up to 8 hours in advance. Perfect for prepping the night before!
To do this simply prepare the casserole as directed and cover well with foil. Place into the fridge and allow to rest overnight until morning.
In the morning set the pan on the counter as the oven preheats. Then bake as directed.
Note that because the hashbrowns were thawed before baking the casserole could be finished cooking in as little as 40 minutes, so checking on the casserole as it bakes could be a great idea to prevent it from overcooking.
🥗 Side Dishes
Serve this casserole up with some Instant Pot Steamed Broccoli and call it a comforting dinner, or serve it up with other breakfast favorites like Baked Scrambled Eggs, and Eggos Waffles French Toast.
Serve it up whenever you want. Just make sure to set your servings aside first because this hashbrown casserole doesn't last long!
👩🏻🍳 Storage
This casserole can be left stored in the fridge in an airtight or well covered container for up to 5 days. Just reheat again before serving.
💭 FAQs
If you don't want to make this easy hash brown casserole with sour cream you can use plain unflavored Grek yogurt in its place. This will give you the same great results but without actually using sour cream.
Because this dish is so perfect for both breakfast and dinner you can serve it alongside just about anything from pancakes and waffles to roasted chicken breasts and salad. I often serve ours at dinner time with a simple green veggie.
Nope! Just add them to a big bowl and mix everything together while they're still frozen. They will leave a nice moisture in the dish as it cooks, so things work out pretty perfectly that way.
