What Kind of Hashbrowns Should I Use?

I usually go with frozen shredded hashbrowns — they’re super convenient and easy to layer in. Just make sure they’re thawed before mixing them in, so everything bakes evenly. You could also use freshly grated potatoes if you prefer, but be sure to rinse and dry them well to remove excess starch.

Options for Substitutions

If you’re dairy-free, you can swap the sour cream for a plant-based alternative and use vegan cheese. Want more protein? Add diced ham or cooked bacon. Don’t have cream of chicken soup? Cream of mushroom or even a homemade béchamel works great. You can also toss in chopped onions, green chilies, or peppers to give it an extra flavor punch.

Ingredients for This Hashbrown Casserole

• Frozen shredded hashbrowns – These are the heart of the casserole, providing a soft interior and crisp, golden top when baked.
• Cheddar cheese – I use sharp cheddar for bold flavor and excellent melting quality. A blend of cheeses also works great.
• Sour cream – Adds creaminess and a touch of tang that balances the richness of the dish.
• Cream of chicken soup – The base that binds everything together with savory depth. Homemade or canned works.
• Butter – Gives the casserole richness and helps achieve that golden-brown top.
• Onion – A little chopped onion adds a subtle crunch and savory background flavor.
• Salt & pepper – Simple seasonings that bring out the best in all the other ingredients.
• Fresh parsley (optional) – For a pop of color and a hint of freshness when serving.

Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C). A moderate temperature ensures even cooking without drying out the top or undercooking the center.

---

Step 2: Prepare the Hashbrown Mixture

In a large mixing bowl, combine the thawed hashbrowns, sour cream, cream of chicken soup, half of the shredded cheese, melted butter, chopped onion, salt, and pepper. Mix everything thoroughly so that the ingredients are evenly distributed.

Step 3: Transfer to a Baking Dish

Grease a 9×13-inch baking dish with butter or non-stick spray. Spoon the hashbrown mixture into the dish and spread it out evenly. Use a spatula to smooth the top.

---

Step 4: Add Cheese Topping

Sprinkle the remaining cheddar cheese evenly over the top of the casserole. This layer will melt and become bubbly and golden during baking.

---

Step 5: Bake Until Golden

Place the dish in the oven and bake for 45 to 55 minutes, or until the top is deeply golden brown and the edges are bubbling. Let it rest for 5–10 minutes after baking so it sets slightly for cleaner slices.

---

Step 6: Garnish and Serve

Sprinkle with chopped fresh parsley before serving for a fresh finish. Serve warm, straight from the baking dish, and enjoy the creamy, cheesy layers in every bite.

How Long to Prepare the Hashbrown Casserole

Prep Time: This casserole takes about 15 minutes to prepare. That includes thawing the hashbrowns (if not already thawed), chopping the onion, and mixing all the ingredients in a single bowl. It’s all very hands-off and simple.

Cook Time: Once prepped, it needs 45–55 minutes in the oven at 350°F (175°C). The baking time allows the cheese to melt thoroughly, the edges to get bubbly, and the top to develop that irresistible golden crust. Let it rest for 5–10 minutes before serving.

Tips for Perfect Hashbrown Casserole

• Make sure the hashbrowns are completely thawed and drained to avoid excess moisture.
• Use sharp cheddar cheese for a richer flavor and better melt.
• Mix the ingredients well to ensure every bite is creamy and cheesy.
• Let it rest after baking to make slicing easier.
• Add a bit of garlic powder or paprika for a flavor twist.

Watch Out for These Mistakes While Cooking

• Using frozen hashbrowns straight from the freezer: This can make your casserole watery and unevenly cooked.
• Not greasing the baking dish: Skipping this step can lead to sticking and make cleanup a pain.
• Overbaking: Baking too long can dry out the casserole. Keep an eye on the top and edges.
• Underseasoning: With rich ingredients like sour cream and cheese, a bit more salt and pepper can help brighten the flavor.
• Crowding the mix-ins: If you add proteins or veggies, don’t overload it or it may not cook through properly.
