Hashbrown casserole is a cozy, comforting dish that’s perfect for breakfast or a simple dinner side. It usually features crispy hashbrowns mixed with creamy cheese, sour cream, and a hint of onion, all baked until golden and bubbly. The mix of crunchy on the outside and creamy on the inside makes every bite inviting and satisfying.

I love making hashbrown casserole when I want something easy but still filling and tasty. One little tip I always follow is to sprinkle a bit of extra cheese or even crushed crackers on top before baking for a fun crunchy finish. It’s a dish that everyone seems to enjoy, and I always hear, “Can I have the recipe?” when I bring it to gatherings.

My favorite way to serve hashbrown casserole is alongside eggs and bacon for a hearty brunch or with a simple green salad for a light dinner. It’s also great to make ahead and reheat because the flavors only get better after a little while. Whenever I eat it, it reminds me of cozy weekend mornings with family, sharing good food and good laughs.

Key Ingredients & Substitutions

Hashbrowns: Frozen shredded hashbrowns give this dish its signature texture and convenience. If you can’t find shredded, diced potatoes work too, but the texture will be chunkier. Fresh potatoes can also be used, just parboil them first.

Butter: Butter adds richness and helps bind ingredients together. You can substitute with margarine or olive oil for a dairy-free option, though you’ll slightly lose some flavor depth.

Sour Cream: This adds creaminess and tang. Greek yogurt is a great substitute if you want a lighter or healthier option. It keeps the creaminess but with a bit more protein.

Cream of Chicken Soup: This brings moisture and flavor. You can swap it for cream of mushroom soup if you want a vegetarian-friendly option. Homemade cream sauces can also work well!

Cheddar Cheese: Sharp cheddar is my favorite for its strong flavor and melting quality. If you prefer milder cheese, use Colby or Monterey Jack. For a different twist, try mixing in some pepper jack.

How Do You Get the Top Crispy and the Inside Creamy?

The secret is balancing moisture and temperature. Here’s how I do it:

• Use thawed hashbrowns and mix with creamy ingredients well to avoid dryness.
• Spread the mixture evenly in the baking dish so it cooks uniformly.
• Sprinkle extra cheese on top for a golden, crispy crust.
• Bake uncovered at 350°F for about 45-55 minutes. This lets the top brown while the inside stays creamy.
• Let the casserole rest for a few minutes after baking—this helps it set and makes it easier to serve.

Following these steps results in a casserole with a bubbly, crisp surface and a tender, tasty center. Trust me, it’s worth the wait!

Equipment You’ll Need

• 9×13-inch baking dish – perfect size for even cooking and easy serving.
• Large mixing bowl – to mix all the ingredients together smoothly.
• Measuring cups and spoons – for accurate ingredient amounts and easy mixing.
• Spoon or spatula – helps stir and spread the casserole evenly in the dish.
• Oven mitts – protect your hands when handling hot dishes.

Flavor Variations & Add-Ins

• Add cooked and crumbled bacon for a smoky, salty kick that pairs well with cheesy potatoes.
• Mix in sautéed mushrooms or bell peppers for extra veggies and a bit of earthiness.
• Use pepper jack cheese instead of cheddar to add a little gentle heat.
• Swap sour cream for plain Greek yogurt to add tang and boost protein.

How to Make Hashbrown Casserole

Ingredients You’ll Need:

• 1 (30 oz) package frozen shredded hashbrowns, thawed
• 1/2 cup (1 stick) unsalted butter, melted
• 1 cup sour cream
• 1 (10.5 oz) can cream of chicken soup (or cream of mushroom soup)
• 2 cups shredded sharp cheddar cheese
• 1 small onion, finely chopped or 1/4 cup onion powder
• 1/2 teaspoon garlic powder (optional)
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper
• Optional garnish: fresh thyme or chopped green onions

How Much Time Will You Need?

This dish takes about 10 minutes to prep and then about 45 to 55 minutes to bake in the oven. After cooking, let it rest for 5 to 10 minutes before serving so it can set nicely.

Step-by-Step Instructions:

1. Prepare Your Oven and Dish:

First, preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or a non-stick spray so your casserole won’t stick.

2. Mix the Creamy Base:

In a large bowl, stir together the melted butter, sour cream, cream of chicken soup, chopped onion (or onion powder), garlic powder, salt, and pepper. Mix until everything is well combined.

3. Combine Hashbrowns and Cheese:

Add the thawed hashbrowns and 1 1/2 cups of the shredded cheddar cheese to your creamy mixture. Stir gently until the hashbrowns are well coated with the mixture.

4. Assemble and Bake:

Spread the hashbrown mix evenly into your prepared baking dish. Sprinkle the remaining 1/2 cup of cheddar cheese evenly on top. Bake uncovered for 45 to 55 minutes, or until the casserole is bubbly and the top turns golden brown and crispy.

5. Rest and Serve:

Once out of the oven, let the casserole sit for 5 to 10 minutes so it sets up. If you’d like, sprinkle with fresh thyme or chopped green onions for a tasty garnish. Serve warm and enjoy your hearty, cheesy hashbrown casserole!

Can I Use Frozen Hashbrowns Directly Without Thawing?

It’s best to thaw the frozen hashbrowns first to avoid excess moisture that can make the casserole soggy. Thaw them in the fridge overnight or place the sealed bag in cold water for quicker thawing, then drain any liquid before mixing.

Can I Substitute the Cream of Chicken Soup?

Yes! Cream of mushroom soup works well as a vegetarian option. You can also make a homemade cream sauce using butter, flour, and milk if you prefer to avoid canned soups.

How Do I Store Leftover Hashbrown Casserole?

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave until warmed through, adding a splash of milk if it seems dry.

Can I Add Meat or Vegetables to This Recipe?

Absolutely! Cooked bacon, sausage, or diced ham make great additions. For veggies, try sautéed mushrooms, bell peppers, or green onions for extra flavor and texture.
