This Breakfast Sausage Casserole is a warm and filling dish perfect for starting your day. It has juicy sausage, fluffy eggs, and soft bread, making every bite enjoyable!
You can make it ahead of time, and it’s great for feeding a crowd. I love it with a dash of hot sauce on top—adds a little kick to the morning! 🌞
Key Ingredients & Substitutions
Breakfast Sausage: You can use either mild or spicy sausage based on your taste preference. If you’re looking for a lighter option, turkey or chicken sausage works well too!
Eggs: Large eggs are perfect for this recipe. If you’re avoiding eggs, try using a flaxseed meal or chickpea flour mixture as a substitute, though the texture will differ slightly.
Cheddar Cheese: I love using sharp cheddar for an extra kick! If you’re looking for a dairy-free option, try a plant-based cheese alternative that melts well.
Hash Browns: Frozen hash browns are super convenient. If you’re feeling adventurous, diced fresh potatoes cooked until soft, or even cauliflower rice can be used for a lower-carb option.
Diced Tomatoes: These are optional, but they add freshness. If you don’t have fresh tomatoes, canned diced tomatoes work just fine—drain the excess liquid to avoid sogginess.
How Do I Ensure My Casserole Has the Perfect Texture?
The texture of your breakfast casserole is key for a great dish. First, ensure your hash browns are thoroughly thawed and dried to prevent excess moisture. If you’re using fresh potatoes, par-cook them before adding them to the dish.
- Cook the breakfast sausage until fully browned in a skillet; breaking it up into small pieces enhances the texture.
- Mix the egg mixture well to combine all flavors and air in for fluffiness.
- Let the casserole rest for a few minutes post-baking—this helps set the layers perfectly.

How to Make a Delicious Breakfast Sausage Casserole
Ingredients You’ll Need:
For the Casserole:
- 1 pound breakfast sausage (mild or spicy)
- 6 large eggs
- 2 cups shredded cheddar cheese
- 2 cups frozen hash browns (thawed)
- 1 cup milk (whole or 2%)
- 1/2 cup diced tomatoes (optional)
- 1/4 cup chopped fresh parsley (plus extra for garnish)
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- Butter or non-stick spray for greasing the pan
How Much Time Will You Need?
This hearty casserole takes around 15 minutes for preparation and 35-40 minutes for baking. So, you’ll need about an hour total, making it a perfect option for lazy weekend breakfasts or family gatherings!
Step-by-Step Instructions:
1. Preheat and Prepare the Pan:
Begin by preheating your oven to 375°F (190°C). While the oven heats, grease a 9×13-inch baking dish with butter or non-stick spray to ensure your casserole doesn’t stick.
2. Cook the Sausage:
In a skillet over medium heat, cook the breakfast sausage until it is fully browned and no longer pink. Use a spoon to crumble it as it cooks. Don’t forget to drain any excess grease to keep your casserole from becoming too oily.
3. Layer the Ingredients:
Spread the cooked sausage evenly across the bottom of your prepared baking dish. Then, sprinkle the thawed hash browns over the sausage. If you’re using diced tomatoes, add them on top as well for an extra burst of flavor!
4. Prepare the Egg Mixture:
In a large bowl, whisk together the eggs, milk, salt, black pepper, garlic powder, and onion powder until everything is smooth. This mixture is what binds all the delicious layers together.
5. Add Cheese and Parsley:
Gently stir in 1 1/2 cups of shredded cheddar cheese and the chopped parsley into your egg mixture. This will give it a cheesy, herby flavor. Yum!
6. Combine the Layers:
Pour the egg and cheese mixture evenly over the sausage and hash browns in the baking dish. Make sure it’s spread out nicely so every bite has flavor.
7. Top with Cheese:
Sprinkle the remaining 1/2 cup of shredded cheddar cheese on top of everything. This will create a lovely crust as it bakes!
8. Bake and Finish:
Bake the casserole uncovered for 35-40 minutes or until the eggs are set and the top is golden brown. If you want a little twist, carefully crack whole eggs on top in the last 5 minutes for a sunny-side-up finish—this is totally optional but adds a fun touch!
9. Let It Rest:
Once baked, remove the casserole from the oven and let it rest for 5 minutes before slicing. This helps it set and makes it easier to serve.
10. Serve and Enjoy:
Garnish with additional fresh parsley for a pop of color and serve warm. Enjoy this comforting breakfast sausage casserole with your family or friends!
This recipe is perfect for any breakfast or brunch occasion, combining satisfying ingredients into one delicious dish. Enjoy every bite!
Can I Use Different Types of Sausage?
Absolutely! You can use any type of breakfast sausage you prefer, including turkey or chicken sausage for a lighter option. Vegan sausage is also a great substitute if you’re looking for a plant-based alternative.
How Do I Store Leftovers?
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, simply warm it in the microwave or oven until heated through. You may want to add a splash of milk to keep it from drying out.
Can I Make This Casserole Ahead of Time?
Yes! You can assemble the casserole the night before, cover it, and refrigerate until you’re ready to bake it the next morning. Just add a few extra minutes to the baking time if it’s coming straight from the fridge!
What Can I Substitute for Hash Browns?
If you don’t have hash browns, diced, cooked potatoes or even cauliflower rice are excellent alternatives. Just ensure any fresh potatoes are cooked through before layering to ensure even cooking in the casserole.
