How to Make Cheesy Sausage Hash Brown Breakfast Casserole
Get ready for a breakfast that’s not only incredibly easy to assemble but also yields a wonderfully satisfying and comforting result. This Cheesy Sausage Hash Brown Breakfast Casserole boasts a perfect balance of savory sausage, tender hash browns, and gooey melted cheese, all bound together by a creamy egg mixture. With a prep time of just 15 minutes and a bake time of around 45-50 minutes, it’s ideal for any morning of the week.
Step-by-Step Instructions
- Preheat Oven and Prepare Baking Dish: Preheat your oven to 350°F (175°C). Lightly grease a 9×13 inch baking dish with butter or cooking spray. This will prevent the casserole from sticking.
- Cook the Sausage and Aromatics: In a large skillet over medium heat, crumble and cook the breakfast sausage until browned and no pink remains. Drain off any excess grease. Add the chopped onion to the skillet with the cooked sausage and cook until softened, about 5-7 minutes. Stir in the minced garlic and cook for an additional minute until fragrant.
- Assemble the Base Layers: Spread the frozen hash brown potatoes evenly in the bottom of the prepared baking dish. If using shredded hash browns, you can press them down slightly to create a more compact base. Sprinkle about half of the cooked sausage, onion, and garlic mixture over the hash browns. Then, evenly distribute 1/2 cup of the shredded cheddar cheese and all of the Monterey Jack cheese over the sausage layer.
- Add Remaining Sausage and Cheese: Top the cheese layer with the remaining sausage, onion, and garlic mixture. Finally, sprinkle the remaining 1/2 cup of cheddar cheese over the top.
- Prepare the Egg Mixture: In a medium bowl, whisk together the 6 large eggs, 2 cups of milk, 1/2 teaspoon of salt, and 1/4 teaspoon of black pepper until well combined and slightly frothy.
- Pour Over the Casserole: Carefully and evenly pour the egg mixture over the entire casserole, ensuring it seeps down into the layers of hash browns and sausage. Gently shake the dish to help distribute the liquid.
- Bake the Casserole: Cover the baking dish loosely with aluminum foil. Bake in the preheated oven for 30 minutes.
- Uncover and Finish Baking: After 30 minutes, remove the foil and continue to bake for another 15-20 minutes, or until the casserole is set in the center, golden brown on top, and the cheese is melted and bubbly. A knife inserted into the center should come out clean.
- Rest and Serve: Let the Cheesy Sausage Hash Brown Breakfast Casserole rest for 5-10 minutes before slicing and serving. This allows the casserole to set up properly, making it easier to cut. Garnish with fresh parsley, if desired.

Storing and Reheating Tips
Storing Leftovers:
- Refrigeration: Once cooled, tightly cover the Cheesy Sausage Hash Brown Breakfast Casserole with plastic wrap or transfer it to an airtight container. It will stay fresh in the refrigerator for up to 3-4 days.
- Freezing: For longer storage, allow the casserole to cool completely. You can freeze the entire casserole or individual portions. Wrap it tightly with plastic wrap, then with aluminum foil, or place it in a freezer-safe container. Frozen casserole will maintain its best quality for up to 2-3 months.
Reheating:
- From Refrigerator: To reheat from the refrigerator, place a portion (or the whole dish) in a preheated oven at 350°F (175°C). Bake for 20-30 minutes for individual portions or 30-40 minutes for a larger portion, until heated through. You can also reheat individual servings in the microwave for 1-2 minutes, or until hot.
- From Freezer: If reheating from frozen, it’s best to thaw it in the refrigerator overnight before reheating in the oven as described above. If you’re in a hurry, you can reheat directly from frozen, but it will take longer (approximately 45-60 minutes in the oven).
