How to Make Best Breakfast Casserole (Hash Browns & Eggs)

Step 1: Prepare Your Ingredients

Gather all of your ingredients to have them ready to go. Preheat your oven to 350°F (175°C) and grease an 8-inch square baking pan. This will ensure that your casserole doesn’t stick, and the cleanup is a breeze. Spread the thawed hash browns evenly across the pan for a crisp base.

Step 2: Cook the Sausage and Onion

In a large skillet over medium heat, cook the pork sausage and diced onion together until the sausage is golden brown and crumbled, about 10 minutes. Don’t forget to drain any excess fat to keep your casserole from becoming too oily.

Step 3: Mix and Layer

In a large bowl, whisk together the eggs, milk, onion powder, garlic powder, salt, and pepper. Pour this mixture over the hash browns and sprinkle with half of the Cheddar cheese. Add the cooked sausage and onion on top and then cover with the remaining cheese. Cover your pan with foil to lock in moisture during baking.

Step 4: Bake to Perfection

Place the covered casserole in the oven and bake for 1 hour. After covering it, bake for an additional 10 minutes until a knife inserted in the center comes out clean. Allow it to rest for 5 minutes before serving, so it sets beautifully.

Pro Tips for Making Best Breakfast Casserole (Hash Browns & Eggs)

Hash Brown Crispiness: Ensure the hash browns are completely thawed to achieve a perfect crispy layer that holds up under the ingredients.
Cheese Melting Magic: Use freshly grated cheese as it melts smoother and more evenly compared to pre-shredded varieties.
Batch Cooking: Double the recipe and use a larger pan for gatherings; this casserole is a crowd-pleaser and reheats wonderfully.
Egg Mixture Extras: Add a teaspoon of Dijon mustard to the egg mixture for a subtle tang that complements the cheesy richness.

How to Serve Best Breakfast Casserole (Hash Browns & Eggs)

Garnishes

A sprinkle of fresh chopped parsley or chives adds a pop of color and a hint of freshness, elevating both the appearance and flavor of your casserole. For a bit of zing, consider a light dusting of smoked paprika.

Side Dishes

Complement this hearty breakfast casserole with simple sides like a fresh fruit salad or a citrusy arugula salad. For a bigger brunch spread, add a platter of buttery croissants or crispy bacon.

Creative Ways to Present

Serve individual pieces on bright, vibrant plates to make the colors of the casserole and its garnishes pop. Cut into squares or slices, and layer them onto a wooden board for a rustic, family-style presentation.

Make Ahead and Storage

Storing Leftovers

Store any leftovers in an airtight container in the refrigerator for up to 3 days. This ensures the casserole remains moist and flavorful when reheated.

Freezing

To freeze, wrap individual portions tightly in plastic wrap and place them in a freezer-safe bag or container. This casserole can be frozen for up to 3 months, making it a fantastic meal prep option.

Reheating

For best results, thaw frozen portions overnight in the fridge, then reheat in the oven at 350°F (175°C) until warm through. Alternately, heat in the microwave for a quick bite.

FAQs

Can I use fresh potatoes instead of frozen hash browns?

Yes, you can grate fresh potatoes. Just be sure to squeeze out excess moisture before adding them to the dish, or they may release too much liquid during baking.
Is it possible to make this casserole vegan?

Absolutely! Use plant-based sausage and cheese, and replace the eggs with a tofu scramble or a prepared egg replacer to enjoy a vegan version.
What can I substitute for pork sausage?

Chicken sausage, turkey sausage, or even vegetarian crumbles work wonderfully if you want a lighter or meat-free option.
How can I make this casserole gluten-free?

The recipe is naturally gluten-free, but always check the labels on your sausage and cheese to ensure there are no added gluten-containing fillers.
