Ingredients You’ll Need

One of the reasons this hash brown casserole is so popular is that it requires simple, accessible ingredients that you likely already have in your pantry and refrigerator. Here’s what you’ll need to gather:

• 1 (2 pound) package frozen hash brown potatoes, thawed
• 2 cups shredded Cheddar cheese
• 1 (10.5 ounce) can condensed cream of chicken soup
• 1 (8 ounce) container sour cream
• 1/2 cup melted butter, divided
• 1/3 cup chopped onion
• 1 teaspoon salt
• 1/4 teaspoon ground black pepper
• 2 cups crushed cornflakes cereal

Kitchen Equipment Required

This recipe requires minimal equipment, making it accessible even for those with basic kitchen setups:

• 9×13-inch baking dish
• Large mixing bowl
• Medium bowl (for cornflake topping)
• Measuring cups and spoons
• Wooden spoon or spatula for mixing

Step-by-Step Instructions

Follow these simple steps to create a perfectly creamy, cheesy hash brown casserole with a delightfully crunchy topping:

Preparation

1. Preheat your oven to 350 degrees F (175 degrees C).
2. Lightly grease a 9×13-inch baking dish with cooking spray or a small amount of butter.
3. If your hash browns are frozen, make sure they’re properly thawed before using them in this recipe. You can thaw them overnight in the refrigerator or place them in a colander and run cool water over them until thawed.

Making the Casserole Base

1. In a large mixing bowl, combine the thawed hash brown potatoes, shredded Cheddar cheese, condensed cream of chicken soup, sour cream, 1/4 cup of melted butter, chopped onion, salt, and pepper.
2. Mix all ingredients thoroughly until well combined and the potatoes are evenly coated with the creamy mixture.
3. Transfer the potato mixture to your prepared 9×13-inch baking dish, spreading it evenly to ensure consistent baking.

Preparing the Crunchy Topping

1. In a medium bowl, combine the crushed cornflakes with the remaining 1/4 cup of melted butter.
2. Mix until the cornflakes are evenly coated with butter.
3. Sprinkle the buttered cornflake mixture evenly over the top of the potato mixture in the baking dish.

Baking the Casserole

1. Bake uncovered in the preheated oven for 45 to 50 minutes, or until the casserole is hot and bubbly and the cornflake topping has turned a golden brown color.
2. If the topping begins to brown too quickly, you can loosely cover the dish with aluminum foil for the remainder of the baking time.
3. Once done, remove from the oven and let the casserole rest for about 5-10 minutes before serving. This allows the casserole to set up slightly and makes it easier to serve.

Recipe Variations and Substitutions

One of the wonderful aspects of this hash brown casserole recipe is its adaptability. Here are some popular variations and substitutions to customize the recipe to your preferences:

Soup Substitutions

• Cream of mushroom soup: For a vegetarian option, substitute cream of mushroom soup for the cream of chicken.
• Cream of celery soup: Offers a slightly different flavor profile while maintaining the creamy texture.
• Homemade cream soup substitute: For those avoiding processed foods, you can create a homemade white sauce with butter, flour, milk, and seasonings.

Cheese Variations

• Cheddar blend: Try using a mixture of sharp cheddar and another cheese like Monterey Jack, Colby, or Gruyère for added depth of flavor.
• Pepper Jack: Add a mild spicy kick by using pepper jack cheese for part or all of the cheddar.
• Reduced-fat cheese: To lighten the recipe, use reduced-fat cheese varieties, though note that they may not melt as smoothly.

Topping Alternatives

• Crushed potato chips: For a different but equally delicious crunch, substitute crushed potato chips for the cornflakes.
• Panko breadcrumbs: Mixed with melted butter and perhaps a little grated Parmesan cheese for a more sophisticated topping.
• French fried onions: These add both crunch and flavor, especially popular during the holiday season.

Add-In Options

• Diced ham or crumbled bacon: For a heartier dish that could serve as a main course.
• Diced bell peppers: Add color and flavor with red, green, or yellow bell peppers.
• Green chilies: For a southwestern twist, add a small can of diced green chilies.
• Broccoli florets: Incorporate some vegetables by adding small broccoli florets to the mixture.

Make-Ahead and Storage Tips

This hash brown casserole is ideal for make-ahead preparation, which can be a lifesaver during busy holidays or when entertaining:

Make-Ahead Instructions

• Prepare without baking: Assemble the casserole up to 24 hours in advance, but wait to add the cornflake topping until just before baking. Cover the dish with plastic wrap and refrigerate.
• Adding the topping: When ready to bake, remove the casserole from the refrigerator about 30 minutes before baking to take the chill off. Add the cornflake topping and bake as directed, adding 5-10 minutes to the baking time if the casserole is still cold.
• Freezer option: You can also freeze the unbaked casserole (without the cornflake topping) for up to 3 months. Thaw completely in the refrigerator overnight before adding the topping and baking.

Storage and Reheating

• Refrigerator storage: Leftover casserole can be covered and refrigerated for up to 3-4 days.
• Reheating in the oven: For best results, reheat individual portions or the entire casserole in a 350°F oven until heated through, about 20-25 minutes for the full casserole or 10-15 minutes for individual portions.
• Microwave reheating: For quick reheating, microwave individual portions on medium power, covered with a paper towel, for 1-2 minutes or until heated through.

Breakfast or Brunch

Nutritional Information and Dietary Considerations

This classic hash brown casserole is undeniably delicious but is also rich and indulgent. Here are some nutritional considerations and potential modifications for different dietary needs:

Standard Recipe Nutritional Profile

The traditional recipe is high in calories, fat (particularly saturated fat), and sodium due to ingredients like cheese, butter, condensed soup, and sour cream. It provides carbohydrates from the potatoes and protein from the dairy components.

Lighter Modifications

• Reduced-fat dairy: Use light sour cream and reduced-fat cheese to lower the fat content.
• Less butter: Reduce the amount of butter used in both the mixture and topping.
• Low-sodium soup: Opt for low-sodium condensed soup to reduce salt content.

Dietary Adaptations

• Gluten-free: Ensure your condensed soup is gluten-free or make a homemade substitute; use gluten-free cornflakes for the topping.
• Vegetarian: Use cream of mushroom or cream of celery soup instead of cream of chicken.
• More vegetables: Add diced vegetables like bell peppers, broccoli, or spinach to increase the nutritional value.

Frequently Asked Questions (FAQs)

Q: Can I use fresh potatoes instead of frozen hash browns?

A: Yes, you can use freshly grated potatoes, but you’ll need to remove excess moisture first. After grating, place the potatoes in a clean kitchen towel and squeeze out as much moisture as possible before proceeding with the recipe.

Q: Why is my hash brown casserole watery?

A: Excess moisture is usually the culprit. Make sure your hash browns are fully thawed and patted dry before mixing with other ingredients. Also, avoid opening the oven frequently during baking, as this can cause temperature fluctuations.

Q: Can I make this casserole in a slow cooker?

A: Yes, you can cook this casserole in a slow cooker on low for 4-5 hours. The cornflake topping won’t get as crispy, so you might consider adding it during the last 30 minutes of cooking or browning it separately under a broiler.

Q: How do I know when the casserole is done baking?

A: The casserole should be bubbling around the edges, hot throughout, and the topping should be golden brown. If you insert a knife in the center, it should come out hot to the touch.

Q: Can I prepare this casserole the night before and bake it in the morning?

A: Absolutely! Prepare the potato mixture and refrigerate overnight. Add the cornflake topping just before baking in the morning. You may need to add 5-10 minutes to the baking time if putting it directly from the refrigerator into the oven.

This classic hash brown casserole has earned its place as a beloved comfort food classic for good reason. With its creamy, cheesy texture, satisfying potato base, and crispy topping, it hits all the right notes for a crowd-pleasing side dish.
