Ingredients:
- 20 ounces shredded hash browns, thawed
- 1 pound ground pork sausage, cooked, crumbled, and drained
- ¼ cup finely diced onion
- ½ red bell pepper, diced
- ½ green bell pepper, diced
- 2 cups shredded cheddar cheese, divided
- 8 large eggs
- 12 ounces evaporated milk (1 can, or 1 ⅓ cups milk)
- ½ teaspoon Italian seasoning (or your favorite herbs and spices, optional)
- ½ teaspoon Kosher salt (or to taste)
- ¼ teaspoon black pepper
Prepare Your Base
The foundation of our Hashbrown Breakfast Casserole is all about getting those textures and flavors ready to mingle. First, ensure your shredded hash browns are fully thawed. This is crucial because frozen hash browns will release too much moisture during baking, leading to a watery casserole. I usually thaw them overnight in the refrigerator, but a quick thaw in the microwave on the defrost setting works in a pinch. Just be careful not to cook them, only to thaw. Once thawed, I like to gently press out any excess water with a paper towel. This little step makes a big difference in the final texture.
Next, let’s talk about the star savory element: the pork sausage. You’ll need to cook and crumble one pound of ground pork sausage. I prefer to cook it in a skillet over medium-high heat, breaking it up as it browns. Once it’s cooked through and no pink remains, drain off all the excess grease. This is important for both flavor and to prevent a greasy casserole. You can use a colander lined with paper towels for efficient draining.
Now, for a little aromatic boost, we’ll add the finely diced onion. Aim for small, uniform pieces so they distribute evenly throughout the casserole and cook down nicely. The red and green bell peppers, also diced, will add a lovely touch of sweetness and a pop of color. Again, consistent dicing ensures they cook at the same rate as the other ingredients. If you’re not a fan of raw onion in your casserole, you can sauté these diced vegetables in a little bit of the drained sausage grease until they’re softened before adding them to the hash brown mixture.
Assemble the Casserole
In a large mixing bowl, combine the thawed and gently pressed shredded hash browns, the cooked and crumbled pork sausage, the finely diced onion, the diced red bell pepper, and the diced green bell pepper. Give everything a good stir to ensure the sausage and vegetables are evenly distributed amongst the hash browns. This creates a beautiful, textured base.
Now, let’s add a portion of our delicious shredded cheddar cheese. Reserve about ½ cup of the cheese for topping later; we want that lovely golden-brown, bubbly crust. Add the remaining 1 ½ cups of shredded cheddar cheese to the hash brown mixture. The cheese will start to melt and bind some of these base ingredients together, adding a wonderful richness.
Create the Custard and Bake
In a separate medium bowl, whisk together the 8 large eggs. This is the binder that will hold our entire Hashbrown Breakfast Casserole together. Once the eggs are well beaten, gradually whisk in the evaporated milk. Evaporated milk provides a richer, creamier texture than regular milk, giving the casserole a luxurious mouthfeel. If you don’t have evaporated milk on hand, 1 ⅓ cups of regular milk will work, but the texture might be slightly less decadent.
Season this egg and milk mixture with the ½ teaspoon of Italian seasoning (if using), the ½ teaspoon of Kosher salt, and the ¼ teaspoon of black pepper. The Italian seasoning is a fantastic addition for an extra layer of flavor, but feel free to swap it for your favorite herb blend like a pinch of thyme, rosemary, or even a little paprika. Taste the mixture before adding it to the casserole; you can always adjust the salt and pepper to your preference.
Pour this seasoned egg and milk custard evenly over the hash brown and sausage mixture in the large bowl. Gently fold everything together using a spatula or large spoon until all the ingredients are moistened by the custard. Be careful not to overmix, as we want to maintain some texture from the hash browns and vegetables.
Now, it’s time to transfer this glorious mixture into your prepared baking dish. I highly recommend greasing a 9×13 inch baking dish generously with butter or cooking spray to prevent any sticking. Spoon the casserole mixture into the dish and spread it out evenly. Ensure the top is relatively flat for even cooking.
Bake to Golden Perfection
Preheat your oven to 375°F (190°C). This temperature is perfect for allowing the casserole to cook through evenly without burning the top. Once your oven is preheated and the casserole is in its dish, bake for approximately 40-45 minutes. During the last 10 minutes of baking, sprinkle the reserved ½ cup of shredded cheddar cheese evenly over the top of the casserole. This will melt into a beautiful golden, bubbly blanket.
You’ll know your Hashbrown Breakfast Casserole is ready when the center is set (a knife inserted near the center comes out clean), the edges are lightly golden brown, and the cheese on top is melted and slightly browned. If you find the top is browning too quickly before the center is cooked, you can loosely tent the dish with aluminum foil.
Once baked, remove the casserole from the oven and let it rest for at least 5-10 minutes before serving. This resting period is essential as it allows the casserole to set further, making it easier to slice and serve. The flavors also have a chance to meld and deepen. Serve warm and enjoy the delicious symphony of flavors and textures!

Frequently Asked Questions:
Can I make this Hashbrown Breakfast Casserole ahead of time?
Absolutely! You can assemble the casserole the night before, cover it tightly with plastic wrap and foil, and refrigerate it. When you’re ready to bake, remove it from the refrigerator about 30 minutes prior to baking to allow it to come closer to room temperature, and then bake as directed. You may need to add a few extra minutes to the baking time.
What kind of potatoes are best for this casserole?
Frozen shredded hash browns are ideal for this recipe because they’re already processed and will cook up beautifully in the casserole, providing that perfect crispy texture. While you could technically use fresh shredded potatoes, they tend to release more moisture, which might alter the final consistency of the casserole.
