- 1/2 teaspoon black pepper: Gives a subtle kick that balances the richness.

How to Make Breakfast Sausage and Cheddar Hash Brown Casserole Recipe
Step 1: Prepare the Oven and Sausage
First, preheat your oven to 375°F and grease a 9×13 inch baking dish to prevent sticking. Then, in a large skillet over medium heat, cook the breakfast sausage until it’s browned and fully cooked through. This step infuses the casserole with rich, meaty flavor. Be sure to drain any excess grease to keep the dish from becoming too oily.
Step 2: Whisk the Egg Mixture
While the sausage cooks, grab a large bowl and whisk together the eggs, whole milk, salt, black pepper, garlic powder, and onion powder. This mixture will soak into the hash browns and sausage, creating that luscious, custardy texture that defines a great breakfast casserole.
Step 3: Assemble the Layers
Spread the thawed hash browns evenly at the bottom of your greased baking dish. Layer the cooked sausage on top, then sprinkle with shredded cheddar cheese, diced bell peppers, and green onions. Each layer adds its own flavor punch and ensures that every scoop of casserole has a perfect balance of ingredients.
Step 4: Pour and Bake
Carefully pour the egg and milk mixture over the assembled ingredients, allowing it to seep in evenly. Slide the dish into your preheated oven and bake for 40 to 45 minutes. You’ll know it’s done when the center is set and the top turns a gorgeous, light golden brown. Let the casserole rest for about 5 to 10 minutes before slicing—this helps it firm up and makes serving easier.
How to Serve Breakfast Sausage and Cheddar Hash Brown Casserole Recipe

Garnishes
Sprinkle fresh herbs such as chopped parsley or cilantro on top just before serving for a burst of color and brightness. A dollop of sour cream or a drizzle of your favorite hot sauce can also elevate the flavors beautifully and add some fun tangy or spicy notes.
Side Dishes
This casserole is a complete meal on its own, but pairing it with fresh fruit salad or a crisp green salad lightens the plate and balances the richness perfectly. Toasted English muffins or warm croissants alongside bring a delightful bread component to scoop up any cheesy leftovers.
Creative Ways to Present
For a fun twist, serve this Breakfast Sausage and Cheddar Hash Brown Casserole Recipe in individual ramekins or muffin tins for portion-controlled servings, ideal for brunch guests or meal prep. Layering in additional veggies like mushrooms or spinach before baking is a fantastic way to sneak in extra nutrition without sacrificing flavor.
Make Ahead and Storage
Storing Leftovers
If you happen to have leftovers (though unlikely!), store them in an airtight container in the refrigerator for up to 3 days. When kept chilled, the flavors actually meld nicely, and reheating is a breeze for quick breakfasts.
Freezing
This casserole freezes wonderfully. Wrap portions tightly in plastic wrap and aluminum foil or use freezer-safe containers. Frozen casserole will keep well up to 2 months. Defrost overnight in the fridge for best results before reheating.
Reheating
Warm individual slices in the microwave or reheat the entire casserole at 350°F until heated through (about 20 minutes if thawed). You’ll want to cover it lightly with foil to avoid drying out while keeping that cheesy, creamy texture intact.
FAQs
Can I use a different type of sausage in this recipe?
Absolutely! Feel free to swap breakfast sausage with cooked bacon, diced ham, or even a vegetarian sausage alternative. Each option will bring its own unique flavor while keeping the spirit of the dish.
Is it possible to make this casserole dairy-free?
Yes, you can substitute the milk with your favorite plant-based milk and use dairy-free cheddar cheese. Keep in mind this might slightly alter the texture and flavor, but it still tastes delicious.
Can I add more vegetables to the casserole?
Definitely. Spinach, mushrooms, tomatoes, or zucchini all make excellent additions. Just sauté them first to remove excess moisture so the casserole doesn’t get watery.
What’s the best way to thaw frozen hash browns for this recipe?
The easiest method is to leave them in the refrigerator overnight. If you’re short on time, place them in a colander and run cold water over them until thawed, then drain thoroughly to avoid sogginess.
How can I make this casserole spicier?
Incorporate diced jalapeños or a pinch of cayenne pepper into the egg mixture, or top with spicy salsa. You can also choose a spicy breakfast sausage to add an extra kick right from the start.
