No frantic scrambling in the kitchen required! This isn’t just breakfast; it’s a warm, comforting hug on a plate, and it’s all thanks to the magic of preparing it the night before.

Hash brown casserole, in its various forms, has been a staple at potlucks, family gatherings, and holiday brunches for generations. While its exact origins are debated, the dish gained immense popularity in the mid-20th century, likely evolving from simple potato gratins and casseroles. It represents a spirit of resourcefulness and community, a way to feed a crowd with readily available ingredients.

What makes this Overnight Hash Brown Casserole so beloved? It’s the perfect combination of creamy, cheesy goodness, the satisfying chew of the hash browns, and the savory depth of the sausage. But beyond the taste, it’s the sheer convenience that truly wins hearts. The ability to assemble it the evening before, allowing the flavors to meld and deepen overnight, frees you up to enjoy precious moments with loved ones. It’s a stress-free way to deliver a crowd-pleasing dish that everyone will rave about. So, let’s get started and create a breakfast masterpiece that will become a tradition in your own home!

Ingredients:

• 1 (30 ounce) package frozen shredded hash browns, thawed
• 1/2 cup butter, melted
• 1 (10.75 ounce) can condensed cream of chicken soup
• 1 pint sour cream
• 1/2 cup chopped onion
• 2 cups shredded cheddar cheese, divided
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper
• 2 cups corn flakes, crushed
• 1/4 cup butter, melted (for topping)

Preparing the Hash Brown Mixture

Okay, let’s get started! This Overnight Hash Brown Casserole is a family favorite, and I’m so excited to share it with you. The best part? You can prep it the night before, making your morning so much easier. First, we’ll focus on getting the hash brown mixture just right.

1. Thaw the Hash Browns: Make sure your hash browns are completely thawed. This is crucial for even cooking and prevents a watery casserole. I usually take them out of the freezer the night before and let them thaw in the refrigerator. If you’re short on time, you can thaw them in the microwave, but be careful not to cook them! Just get them soft enough to work with.
2. Melt the Butter: In a microwave-safe bowl or in a saucepan on the stovetop, melt 1/2 cup of butter. You want it completely melted and smooth. This butter will add richness and flavor to the hash browns.
3. Combine the Ingredients: In a large bowl, combine the thawed hash browns, melted butter (the 1/2 cup), cream of chicken soup, sour cream, and chopped onion. Make sure everything is well combined. I like to use a large spoon or spatula to gently fold the ingredients together.
4. Add Cheese and Seasonings: Add 1 1/2 cups of the shredded cheddar cheese (reserving the other 1/2 cup for topping), salt, and pepper to the hash brown mixture. Again, gently fold everything together until it’s evenly distributed. Taste the mixture and adjust the seasonings if needed. Some people like to add a little garlic powder or paprika for extra flavor.

Assembling the Casserole

Now that our hash brown mixture is ready, it’s time to assemble the casserole. This is where the magic happens, and we get one step closer to that cheesy, delicious goodness!

1. Prepare the Baking Dish: Grease a 9×13 inch baking dish. You can use cooking spray or butter to grease the dish. This will prevent the casserole from sticking and make it easier to serve.
2. Pour in the Hash Brown Mixture: Pour the hash brown mixture into the prepared baking dish and spread it evenly. Use a spatula to smooth the top.
3. Cover and Refrigerate (Overnight): Cover the baking dish tightly with plastic wrap or aluminum foil and refrigerate overnight. This allows the flavors to meld together and the hash browns to soften even more. If you don’t have time to refrigerate it overnight, you can bake it immediately, but the flavors won’t be as developed.

Preparing the Topping

The topping is what takes this casserole from good to amazing! The crunchy corn flakes and melted butter add a wonderful texture and flavor that complements the cheesy hash browns perfectly.

1. Crush the Corn Flakes: In a resealable plastic bag, crush the corn flakes. You can use a rolling pin or your hands to crush them. You want them to be finely crushed, but not completely powdered.
2. Melt the Butter (for Topping): In a microwave-safe bowl or in a saucepan on the stovetop, melt the remaining 1/4 cup of butter.
3. Combine Corn Flakes and Butter: In a bowl, combine the crushed corn flakes and melted butter. Mix well until the corn flakes are evenly coated with butter.

Baking the Casserole

Finally, it’s time to bake our Overnight Hash Brown Casserole! The aroma that fills your kitchen while it’s baking is simply irresistible.

1. Preheat the Oven: Preheat your oven to 350°F (175°C).
2. Remove from Refrigerator: Remove the casserole from the refrigerator about 30 minutes before baking. This will help it bake more evenly.
3. Sprinkle with Cheese: Sprinkle the remaining 1/2 cup of shredded cheddar cheese evenly over the top of the casserole.
4. Add the Corn Flake Topping: Sprinkle the buttered corn flake mixture evenly over the cheese.
5. Bake: Bake in the preheated oven for 45-55 minutes, or until the casserole is golden brown and bubbly. The internal temperature should reach 165°F (74°C).
6. Let it Rest: Let the casserole rest for 5-10 minutes before serving. This will allow it to set up a bit and make it easier to slice.

Serving Suggestions

This Overnight Hash Brown Casserole is delicious on its own, but it’s also great served with other breakfast or brunch dishes. Here are a few of my favorite serving suggestions:

• With Eggs and Bacon: Serve alongside scrambled eggs, fried eggs, or an omelet, and crispy bacon or sausage.
• As a Side Dish: Serve as a side dish for a holiday brunch or potluck.
• With Fruit Salad: Pair with a refreshing fruit salad for a balanced meal.
• Add a Protein: Top with cooked ham, crumbled sausage, or shredded chicken for a heartier meal.

Here are a few tips and variations to help you customize this recipe to your liking:

• Make it Spicy: Add a pinch of cayenne pepper or a dash of hot sauce to the hash brown mixture for a little heat.
• Use Different Soup: Try using cream of mushroom soup or cream of celery soup instead of cream of chicken soup.
• Make it Gluten-Free: Use gluten-free cream of chicken soup and gluten-free corn flakes to make this casserole gluten-free.
