How to Make Hashbrown Breakfast Casserole Recipe
Step 1: Preheat and Prepare the Pan
Begin by setting your oven to 350°F and greasing a 9×13-inch casserole dish generously with cooking spray. This step ensures your casserole won’t stick and makes cleanup a breeze, so you can focus on enjoying your delicious breakfast later.
Step 2: Cook the Sausage
Heat a large skillet over medium-high heat and cook the sausage, breaking it up with a spoon as it browns. Cook until there’s no pink left, then drain off the fat. The cooked sausage adds a savory, meaty depth that forms the heart of this breakfast casserole, infusing every bite with bold flavor.
Step 3: Assemble the Casserole
In your prepared dish, combine the thawed hashbrowns, cooked sausage, diced onions, and both red and green bell peppers. Sprinkle 1 ½ cups of shredded cheddar cheese over the mixture. Gently stir everything together so the ingredients are evenly distributed, then spread it out in an even layer. This mixture forms a colorful, flavorful bed for the eggs and cheese to shine atop.
Step 4: Prepare the Egg Mixture
In a large bowl, vigorously whisk together the eggs, evaporated milk, salt, pepper, and if you’re using it, Italian seasoning. This rich, creamy custard mixture will gently soak into the hashbrowns and sausage, giving your casserole a light yet satisfying texture that holds it all together perfectly.
Step 5: Combine and Top
Pour the egg mixture evenly over the hashbrown mixture in the casserole dish, making sure it seeps through to coat everything below. Then sprinkle the remaining ½ cup of cheddar cheese on top. This final sprinkling creates a gorgeous golden crust as it bakes, adding melty, cheesy goodness to every forkful.
Step 6: Refrigerate or Bake
You have the option to cover and refrigerate this casserole overnight, which allows the flavors to meld beautifully and is perfect for easy mornings. If doing so, bring the dish out 30 minutes before baking. Otherwise, you can bake the casserole immediately and start savoring it in just over an hour.
Step 7: Bake the Casserole
Bake your breakfast masterpiece uncovered for 55 to 65 minutes. You’ll know it’s done when the eggs are fully set and the cheese is bubbling and golden brown on top. Let it cool slightly before digging in so the casserole holds its shape with each serving.

Make Ahead and Storage
Storing Leftovers
Store any leftover casserole in an airtight container in the refrigerator for up to 3-4 days. When reheating, cover it to keep moisture in and avoid drying out the dish so it stays just as delicious as the first serving.
Freezing
This casserole freezes beautifully! Wrap it tightly with plastic wrap and then foil before freezing. It can be frozen for up to 2 months, perfect for meal prepping or saving for a future quick breakfast.
Reheating
Reheat individual portions in the microwave or warm the whole casserole in a 350°F oven until heated through. Cover with foil to prevent over-browning and retain moisture. Reheating only takes about 15-20 minutes depending on portion size.
FAQs
Can I use a different type of meat in this casserole?
Absolutely! Feel free to swap sausage for cooked bacon, ham, or even a vegetarian meat substitute. Each option brings its own twist while keeping the hearty spirit of the casserole intact.
What can I use if I don’t have evaporated milk?
If you don’t have evaporated milk, you can substitute with an equal amount of regular milk mixed with a tablespoon of powdered milk for richness, or simply use whole milk for a lighter texture.
Can I make this casserole gluten-free?
Definitely! This recipe is naturally gluten-free as long as you use gluten-free sausage and ensure your seasoning blends don’t contain gluten. It’s perfect for those avoiding gluten but wanting a comforting breakfast.
Is it better to bake the casserole immediately or refrigerate overnight?
Both methods work wonderfully. Baking immediately gives you a warm meal in under two hours, while refrigerating overnight allows flavors to deepen and makes your morning easier by just popping it in the oven.
How do I keep the casserole from becoming soggy?
Using thawed, well-drained hashbrowns and cooked sausage ensures minimal excess moisture. Also, baking uncovered lets the casserole’s surface crisp up nicely, avoiding any sogginess.
