This Hashbrown Breakfast Casserole is a hearty dish perfect for any morning. It has crispy hashbrowns, eggs, cheese, and your choice of tasty add-ins like sausage or veggies!
I love how you can make this the night before—just pop it in the oven in the morning. Easy peasy! It’s like a warm hug on a plate. ☀️🥔
Key Ingredients & Substitutions
Hashbrowns: Frozen shredded hashbrowns are a time-saver and provide great texture. If you don’t have them, you can use freshly grated potatoes; just make sure to soak and dry them to prevent excess moisture.
Breakfast sausage: I love the flavor of cooked and crumbled breakfast sausage in this casserole. If you prefer a leaner option, turkey sausage works well. For a vegetarian version, try using crumbled veggie sausage or mushrooms.
Pepper and onion: Diced red bell pepper adds sweetness and color, while onion brings depth. Feel free to substitute with other veggies like spinach, zucchini, or even diced potatoes for a different twist.
Cheddar cheese: I use sharp cheddar because it has a stronger flavor. You can easily swap it for mozzarella, Monterey Jack, or even a vegan cheese if you’re avoiding dairy.
Eggs: Essential for binding the casserole. If you need an egg substitute, try using flax eggs (1 tablespoon ground flaxseed mixed with 2.5 tablespoons water per egg) or a commercial egg replacer.
How Do I Ensure My Casserole is Perfectly Set?
Cooking this casserole just right is key! To make sure it’s cooked through and not watery, follow these steps:
- Preheat your oven properly to 350°F (175°C) before baking.
- Bake uncovered for 55-60 minutes. You want it to be golden on top.
- Use a toothpick or knife to check doneness; it should come out clean when inserted in the center.
- Let it rest for 5-10 minutes after baking. This helps it firm up and makes slicing much easier!
Using these tips will help you serve up a delicious, satisfying casserole that everyone will love! Enjoy your cooking!

- 1/2 cup chopped onion
- 2 cups shredded cheddar cheese, divided

How Much Time Will You Need?
This Hashbrown Breakfast Casserole takes about 15 minutes of prep time and requires about 55-60 minutes in the oven. Allow an additional 5-10 minutes for resting after baking. So, you can have this delicious dish ready in just over an hour!
Step-by-Step Instructions:
1. Prepare Your Oven and Dish:
Start by preheating your oven to 350°F (175°C). While it’s heating up, grease a 9×13-inch baking dish with cooking spray or butter to prevent sticking.
2. Mix the Hashbrown Base:
In a large bowl, combine the thawed hashbrowns, cooked sausage, diced red bell pepper, chopped onion, and 1 1/2 cups of shredded cheddar cheese. Give it a good mix so everything is evenly combined. Once mixed, spread this mixture evenly in the greased baking dish to form the base of your casserole.
3. Whisk the Egg Mixture:
In another bowl, crack the 10 large eggs and add the milk, salt, black pepper, and garlic powder. Whisk everything together until well combined and frothy. This will be the mixture that brings everything together!
4. Pour the Egg Mixture:
Now, pour the egg mixture over the hashbrown base in your baking dish. Make sure to cover everything evenly.
5. Cheese it Up:
Finally, sprinkle the remaining 1/2 cup of shredded cheddar cheese over the top of the casserole for a delicious cheesy crust.
6. Bake the Casserole:
Place the baking dish in the preheated oven and bake uncovered for about 55-60 minutes. You’ll know it’s ready when the center is set and the top is golden brown.
7. Rest and Garnish:
Once it’s out of the oven, be sure to let it rest for about 5-10 minutes. This will help it hold its shape when you slice it. Before serving, sprinkle the chopped green onions on top for a fresh flavor and presentation.
This casserole is not just delicious; it’s also versatile—you can prepare it the night before and pop it in the oven in the morning! Enjoy your hearty breakfast!
Can I Use Fresh Hashbrowns Instead of Frozen?
Absolutely! If you prefer fresh hashbrowns, just make sure to soak and thoroughly dry them to remove excess moisture before mixing them with the other ingredients.
Can I Make This Casserole Ahead of Time?
Yes, you can prepare it the night before! Assemble the casserole, cover it tightly with plastic wrap, and refrigerate overnight. In the morning, just bake it straight from the fridge; you may need to add a few extra minutes to the baking time.
How Do I Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. To reheat, simply warm it in the microwave or oven until heated through. You can sprinkle a little extra cheese on top before reheating for added deliciousness!
What Other Ingredients Can I Add?
This casserole is very versatile! Feel free to add cooked bacon, sautéed spinach, or even different cheeses like Monterey Jack or pepper jack for a bit of spice. You can customize it to your liking!
