What Is Hash Brown Egg Casserole?

Ingredients Needed for Hash Brown Egg Casserole

To whip up this delicious dish, you’ll need the following ingredients:

• 20 ounces frozen shredded hash browns, thawed
• 8 large eggs
• 1 1/3 cups milk (preferably whole milk)
• 1 1/2 cups shredded sharp cheddar cheese
• 1 cup cooked breakfast sausage or diced cooked chicken
• 1/2 cup diced onion
• 1/2 teaspoon garlic powder
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper
• Cooking spray or butter for greasing

This set of ingredients ensures a flavorful, creamy, and hearty casserole that will please every guest at your table.

Kitchen Equipment Required

Fortunately, making this Hash Brown Egg Casserole requires minimal equipment, making it an ideal choice for busy cooks. Here’s what you’ll need:

• 9×13 inch baking dish
• Large mixing bowl
• Whisk
• Measuring cups and spoons
• Spatula or wooden spoon
• Oven

A simple, no-fuss setup guarantees that you can get this dish prepped and ready for the oven in no time at all.

How to Make the Perfect Hash Brown Egg Casserole Step-by-Step

To start, preheat your oven to 350°F (175°C). Lightly grease a 9×13 inch baking dish with butter or cooking spray to prevent sticking.

Next, in a large mixing bowl, whisk together the eggs, milk, garlic powder, salt, and black pepper until fully combined and slightly frothy. This step is crucial because it ensures a light and airy texture in your final casserole.

Now, add the thawed hash browns, cooked sausage or chicken, diced onion, and shredded cheddar cheese into the bowl. Stir gently to evenly coat all the ingredients with the egg mixture.

Pour the entire mixture into your prepared baking dish, spreading it out into an even layer with a spatula.

Bake uncovered for 45–55 minutes, or until the center is set and the top is golden brown. It’s important to let the casserole rest for about 5–10 minutes after removing it from the oven before slicing. This allows the casserole to firm up slightly and makes serving much easier.

Tips for the Best Hash Brown Egg Casserole Every Time

First, always thaw and drain the hash browns thoroughly to prevent excess moisture from making your casserole soggy. Using a paper towel to pat them dry can help even more.

Second, whisk your eggs and milk very well. This creates a creamy and consistent custard that evenly envelops the potatoes.

Additionally, shred your own cheese if possible instead of using pre-shredded. Freshly shredded cheese melts better and creates a smoother texture.

Finally, don’t rush the baking time. If you cut into the casserole too early, you might end up with a runny center. Always check by inserting a knife into the middle; it should come out clean when the casserole is fully baked.

Common Mistakes to Avoid When Preparing Hash Brown Egg Casserole

One common mistake is using frozen hash browns straight from the freezer. Always make sure they are completely thawed and drained to avoid a watery casserole.

Another mistake is overbaking. Although you want a golden top, baking the casserole for too long can dry it out and create an unpleasant texture.

Moreover, under-seasoning is a frequent error. Because potatoes and eggs are relatively mild in flavor, seasoning the mixture well with salt, pepper, and spices is absolutely key to a delicious result.

Recipe Variations and Ingredient Swaps for Hash Brown Egg Casserole

Feel free to make this Hash Brown Egg Casserole your own! You can easily swap the breakfast sausage for diced cooked chicken, turkey sausage, or even a plant-based alternative for a vegetarian version.

For a veggie boost, add in diced bell peppers, sautéed mushrooms, spinach, or zucchini. You could also experiment with different cheeses like Monterey Jack, pepper jack, or Swiss for unique flavor profiles.

If you prefer a spicy kick, sprinkle in some crushed red pepper flakes or diced jalapeños into the egg mixture. The variations are endless, making this recipe adaptable to every palate.

How to Serve and Present Hash Brown Egg Casserole Beautifully

Presentation matters, especially if you are serving guests! Slice the casserole into neat squares and arrange them on a large platter. Garnish with freshly chopped parsley or chives for a pop of color.

You can also serve it with a side of fresh fruit, a light green salad, or a warm basket of biscuits. Additionally, placing the casserole squares into individual ramekins before baking offers a charming, personalized presentation for brunch gatherings.

How to Store and Reheat Leftover Hash Brown Egg Casserole

Leftover casserole stores wonderfully, making it perfect for meal prep. Allow the casserole to cool completely before covering tightly with foil or transferring to an airtight container. It will stay fresh in the refrigerator for up to 4 days.

To reheat, place individual portions in the microwave for about 1–2 minutes until warmed through. For best results, reheat larger portions in a 325°F oven, covered with foil, for 15–20 minutes.

What to Serve with Hash Brown Egg Casserole

This dish pairs beautifully with a variety of sides. A simple mixed greens salad with a light vinaigrette can balance out the richness of the casserole.

Alternatively, serve it alongside roasted vegetables, sliced avocado, or a refreshing fruit salad for a complete and colorful meal.

And if you are feeling indulgent, a side of crispy breakfast potatoes or baked sweet potatoes would complement it perfectly.
