Recommended Products for This Recipe
Over the years of making this casserole, I’ve found a few products that really make a difference in the final result. These aren’t necessary, but they’ll definitely elevate your dish.
1. Le Creuset Enameled Cast Iron Baking Dish
This baking dish distributes heat so evenly that you get perfectly crispy edges and a creamy center every single time.
The enameled interior makes cleanup incredibly easy, even with all that baked-on cheese.
2. Tillamook Extra Sharp Cheddar Cheese Block
I always buy a block of quality sharp cheddar and shred it myself for this recipe.
Pre-shredded cheese has anti-caking agents that prevent it from melting as smoothly, and the flavor just doesn’t compare to freshly shredded cheese from a good quality block.
3. OXO Good Grips Box Grater
If you’re going to shred your own cheese (and you should), this grater makes the job so much easier.
The comfortable grip and sharp blades mean you can shred a block of cheese in under a minute.
4. Simply Organic Garlic Powder
Good quality garlic powder makes a real difference in the flavor of this casserole. This organic version has a clean, potent garlic flavor without any off-putting chemical taste.
Step-by-Step Instructions: How to Make Cheesy Hashbrown Casserole
Follow these detailed steps to create the perfect cheesy hashbrown casserole. I’ve broken down every part of the process so even first-time cooks can nail this recipe.
1. Prepare Your Oven and Baking Dish
- Preheat your oven to 350°F (175°C).
- Grease your 9×13 inch baking dish generously with butter or cooking spray to prevent sticking.
- Set the prepared dish aside while you mix the casserole ingredients.
2. Thaw and Prepare the Hashbrowns
- If your hashbrowns are still frozen, place them in the refrigerator overnight to thaw completely.
- Alternatively, you can microwave them on the defrost setting for a few minutes, stirring occasionally.
- Once thawed, pat the hashbrowns dry with paper towels to remove excess moisture.
- This step is important because excess water can make your casserole soggy instead of creamy.
3. Dice the Onion
- Peel and finely dice your small onion into pieces about 1/4 inch in size.
- The smaller the dice, the better the onion will distribute throughout the casserole.
- If you’re sensitive to onion, you can soak the diced pieces in cold water for 5 minutes to mellow the flavor.
4. Mix the Creamy Base
- In a large mixing bowl, combine both cans of cream of chicken soup.
- Add the 16 oz of sour cream to the bowl.
- Pour in 1/2 cup of melted butter.
- Add the finely diced onion to the mixture.
- Sprinkle in 1 teaspoon of garlic powder.
- Add salt and black pepper to taste (I typically use about 1/2 teaspoon of each).
- Whisk everything together until you have a smooth, well-combined mixture with no lumps.
5. Add the Hashbrowns and Cheese
- Add the thawed and dried hashbrowns to your creamy mixture.
- Reserve 1 cup of the shredded cheddar cheese for later and add the remaining 2 cups to the bowl.
- Using a large spoon or spatula, fold everything together gently but thoroughly.
- Make sure every bit of hashbrown is coated in the creamy mixture.
- The mixture should look thick and creamy, with the hashbrowns evenly distributed throughout.
6. Transfer to Baking Dish
- Pour the hashbrown mixture into your prepared 9×13 inch baking dish.
- Use a spatula to spread it evenly across the dish, making sure to reach all the corners.
- Press down gently to create an even layer without any air pockets.
- Sprinkle the reserved 1 cup of shredded cheddar cheese evenly over the top.
7. Prepare the Cornflake Topping
- In a medium bowl, add 2 cups of cornflakes.
- Crush them gently with your hands or the back of a spoon until they’re coarsely crushed.
- You want some texture remaining, not fine crumbs.
- Drizzle 4 tablespoons of melted butter over the crushed cornflakes.
- Toss with a fork until all the cornflakes are evenly coated with butter.
- Sprinkle this buttery cornflake mixture evenly over the cheese layer.
8. Bake the Casserole
- Cover the baking dish tightly with aluminum foil.
- Place it in your preheated 350°F oven.
- Bake covered for 55 minutes.
- Remove the foil carefully (watch out for steam).
- Return the uncovered casserole to the oven for an additional 10 minutes.
- This final uncovered baking time allows the cornflake topping to become golden and crispy.
- The casserole is done when the edges are bubbling and the top is golden brown.
9. Rest and Serve
- Remove the casserole from the oven and let it rest for 10 minutes before serving.
- This resting time allows the casserole to set up, making it easier to cut and serve.
- Cut into squares and serve hot with your favorite breakfast or dinner items.
This pairs beautifully with my Omelet Recipe for a complete breakfast spread.
Tips for The Best Cheesy Hashbrown Casserole
After making this casserole countless times, I’ve picked up some tricks that make a real difference in the final result.
- Always thaw and dry your hashbrowns: This is the single most important tip. Frozen hashbrowns release too much water during baking, which makes the casserole watery instead of creamy.
- Don’t skip the resting time: Letting the casserole sit for 10 minutes after baking allows it to firm up and makes serving so much easier.
- Use real butter: Margarine or butter substitutes won’t give you the same rich flavor or crispy topping.
- Shred your own cheese: Pre-shredded cheese contains anti-caking agents that prevent it from melting smoothly. Freshly shredded cheese melts better and tastes better.
- Adjust the salt carefully: Both the soup and cheese contain salt, so taste your mixture before adding more.
- Crush cornflakes to different sizes: Having some larger pieces and some smaller crumbs creates a better texture in the topping.
- Don’t overbake: Watch the casserole during the final 10 minutes. You want golden brown, not burnt.
- Make it ahead: You can assemble this completely the night before, cover it, and refrigerate. Just add 10-15 minutes to the covered baking time if baking from cold.

- Add protein: Stir in 2 cups of cooked, crumbled bacon, diced ham, or cooked sausage to make it a complete meal.
- Try different soups: Swap the cream of chicken for cream of mushroom or cream of celery soup for a different flavor profile.
- Mix up the cheese: Use a combination of cheddar, Monterey Jack, and mozzarella for extra melty goodness.
- Go spicy: Add diced jalapeños or a can of diced green chiles for a kick of heat.
- Add vegetables: Fold in a cup of frozen peas, diced bell peppers, or steamed broccoli florets.
- Change the topping: Use crushed Ritz crackers, panko breadcrumbs, or even crushed potato chips instead of cornflakes.
- Make it lighter: Use reduced-fat soup and sour cream, and decrease the butter by half.
- Add fresh herbs: Stir in chopped fresh chives, parsley, or green onions for a pop of color and flavor.

Storage and Reheating

- Refrigerating: Let the casserole cool completely, then cover tightly with plastic wrap or transfer to an airtight container. It will keep in the refrigerator for up to 5 days.

- Reheating in the oven: Cover with foil and bake at 350°F for 20-25 minutes until heated through. Remove the foil for the last 5 minutes to crisp up the topping.
- Reheating in the microwave: Place individual portions on a microwave-safe plate and heat for 1-2 minutes, checking and stirring halfway through.
- Reheating from frozen: Thaw overnight in the refrigerator before reheating, or bake from frozen at 350°F covered for 45-50 minutes, then uncovered for 10 minutes.

FAQs About Cheesy Hashbrown Casserole
1. Can I use fresh potatoes instead of frozen hashbrowns?
Yes, you absolutely can. Peel and shred about 2 pounds of russet potatoes using a box grater.
Rinse the shredded potatoes in cold water to remove excess starch, then squeeze them dry in a clean kitchen towel before adding to the casserole mixture.
2. Why is my casserole watery?
The most common reason is not thawing and draining the hashbrowns properly. Frozen hashbrowns contain a lot of ice that melts during baking and creates excess liquid.
Always thaw your hashbrowns completely and pat them dry with paper towels before mixing them into the casserole.
3. Can I make this casserole without cream of chicken soup?
Yes, you can make a homemade substitute. Melt 4 tablespoons of butter in a saucepan, whisk in 6 tablespoons of flour, then slowly whisk in 1 1/3 cups of chicken broth and 1 cup of milk.
Simmer until thickened, then use this mixture in place of the canned soup.
4. How do I know when the casserole is done baking?
The casserole is done when the edges are bubbling vigorously and the top is golden brown. If you insert a knife into the center, it should come out hot.
The internal temperature should reach 165°F if you want to check with a thermometer.
5. Can I assemble this the night before?
Absolutely, and I do this all the time for holiday mornings. Prepare the casserole completely through step 7, cover it tightly with plastic wrap or foil, and refrigerate overnight.
When you’re ready to bake, remove it from the fridge while the oven preheats, then add about 10-15 extra minutes to the covered baking time since you’re starting with a cold dish.
