Ingredients You'll Need

Here’s the simple lineup of ingredients required for this hearty Egg Hash Brown Sausage Casserole.
- Breakfast Sausage: 1 pound of your favorite ground breakfast sausage (pork, turkey, or even spicy Italian sausage works great).
- Frozen Hash Browns: One 20-ounce bag of shredded hash browns, thawed and patted dry. This is key to avoiding a soggy casserole!
- Large Eggs: 8 large eggs create the rich, fluffy custard base.
- Milk: 1 cup of milk (whole milk or 2% is best for richness).
- Shredded Cheddar Cheese: 1 ½ cups of sharp or medium cheddar cheese, shredded from a block for the best melt.
- Seasonings: A simple but powerful trio of ½ teaspoon salt, ¼ teaspoon black pepper, ½ teaspoon garlic powder, and ½ teaspoon onion powder.
Step-by-Step Instructions: How to Make It
Ready to build the perfect breakfast bake? Follow these simple steps.
Preheat and Prep: First, preheat your oven to 375°F (190°C). Thoroughly grease a 9×13-inch baking dish with butter or non-stick spray. This ensures your slices come out cleanly.
Cook the Sausage: In a large skillet over medium-high heat, cook the breakfast sausage, using a spatula to break it into small crumbles. Cook until it's fully browned with no pink remaining. Crucial step: Drain the grease completely before moving on.
Lay the Foundation: Spread your thawed and dried hash browns in an even layer across the bottom of the prepared baking dish. For an extra-crispy base, you can briefly pan-fry the hash browns in the skillet before adding them to the dish.
Assemble the Layers: Sprinkle the cooked sausage crumbles evenly over the hash brown layer.
Create the Egg Mixture: In a large mixing bowl, whisk together the eggs, milk, salt, pepper, garlic powder, and onion powder until the mixture is uniform and slightly frothy.
Pour and Top: Gently pour the egg mixture over the sausage and hash browns, ensuring it covers everything. Sprinkle the shredded cheddar cheese evenly over the top.
Bake to Golden Perfection: Bake for 35-40 minutes, or until the center is set (a knife inserted in the middle comes out clean) and the cheese is beautifully golden and bubbly.
Rest and Serve: Let the casserole rest on a wire rack for 5-10 minutes. This allows it to set up, making it much easier to slice and serve. Garnish with fresh parsley or chives if desired.
Pro Tips for the Perfect Breakfast Casserole
Avoid common pitfalls and guarantee a flawless dish every time with these expert tips.
### Thaw and Dry Your Hash Browns
This is the most important tip! Frozen hash browns release a lot of water as they cook, which can lead to a watery casserole. Thaw them completely, then squeeze out the excess moisture using a clean kitchen towel or paper towels.
### Don't Overbake the Eggs
Keep an eye on the casserole towards the end of its baking time. You want the center to be just set, not hard. Overbaking can lead to a rubbery texture.
### Shred Your Own Cheese
While pre-shredded cheese is convenient, it contains anti-caking agents that prevent it from melting as smoothly. Grating a block of cheese yourself results in a much creamier, gooier texture.
Variations and Customizations
Make this hashbrown casserole your own with these delicious ideas.
- Make it Spicy: Add a pinch of red pepper flakes to the egg mixture, use spicy sausage, and swap the cheddar for pepper jack cheese.
- Veggie-Loaded: Sauté 1 cup of diced bell peppers, onions, or mushrooms and add them with the sausage. A handful of fresh spinach is also a great addition.
- Healthier Hash Brown Breakfast Casserole: To lighten it up, use turkey sausage, low-fat milk, and reduced-fat cheese. You can also add more veggies like spinach and bell peppers.
- "Cracked Out" Style: For a super indulgent twist, add ½ cup of crumbled cooked bacon and 1-2 tablespoons of dry ranch seasoning mix to the egg mixture.
Storage, Reheating, and Make-Ahead Magic
- To Make Ahead: Assemble the entire casserole (without baking), cover it tightly with plastic wrap or foil, and refrigerate for up to 24 hours. When ready to bake, remove it from the fridge while the oven preheats and add 5-10 minutes to the baking time.
- To Store: Let the casserole cool completely, then cover and store in the refrigerator for up to 4 days.
- To Reheat: Reheat individual slices in the microwave for 60-90 seconds or until warmed through. You can also reheat the casserole in a 350°F (175°C) oven for 10-15 minutes.
Sausage Hash Brown Casserole: Your Questions Answered (FAQ)
Can I use fresh potatoes instead of frozen hash browns?
Absolutely! Grate about 4 medium russet potatoes. To remove starch and moisture, soak the shreds in cold water for 10 minutes, then drain and squeeze them completely dry in a kitchen towel before using.
Can I make this dairy-free?
Yes. You can substitute the milk with unsweetened almond or oat milk and use your favorite dairy-free shredded cheese alternative.
My casserole turned out watery. What went wrong?
The most common culprits are not thawing and drying the hash browns completely or not draining all the grease from the sausage. Both steps are essential for the best texture
