- 1 pound Italian Sausage, cooked
- 1 yellow onion, chopped, sautéed in sausage grease
- 7 large eggs

Notes & Substitutions
You can easily adjust this recipe to suit your preferences or what you have on hand. Feel free to experiment with different flavors to make this breakfast casserole uniquely yours.
- Sausage Alternatives: Substitute Italian sausage with ground pork sausage, turkey sausage, or even diced ham. Ensure you cook any ground meat thoroughly before adding.
- Other Cheese Types: Monterey Jack, Colby, or a Mexican blend all melt beautifully. Sharp cheddar adds a bolder flavor if you prefer.
- Fresh vs. Frozen Potatoes: While frozen diced hash browns are convenient and recommended, you can use fresh diced potatoes. Par-boil them first for about 5-7 minutes to ensure they cook through evenly in the casserole.
- Milk Substitutes: Heavy cream or half-and-half will make the casserole richer and creamier. For a dairy-free option, unsweetened almond milk can work, though the texture might be slightly different.
- Optional Additions: Boost the nutrition and flavor with diced bell peppers, spinach, mushrooms, or a pinch of garlic powder. Add a dash of hot sauce or red pepper flakes for some heat.
Equipment
You only need a few basic kitchen tools to whip up this amazing breakfast. Having the right equipment ensures a smooth cooking process and perfect results every time.
- 9×13 inch Casserole Dish: Essential for baking your breakfast casserole evenly.
- Large Mixing Bowls: For combining all the ingredients.
- Skillet: To cook the sausage and onion.
- Measuring Cups and Spoons: For accurate ingredient portions.
- Whisk: To beat the eggs and milk.
Instructions
Follow these simple steps to create a delicious and satisfying Cheesy Potato Breakfast Casserole. This straightforward process ensures a perfect breakfast every time, even for beginners.
- Preheat Oven & Prep Dish: Preheat your oven to 350°F (175°C). Lightly spray a 9×13-inch casserole dish with non-stick cooking spray. Set the prepared dish aside.
- Prepare Sausage and Onions: In a large skillet over medium heat, cook the Italian sausage, breaking it apart with a spoon until no longer pink. Drain off most of the grease, leaving about a tablespoon in the pan. Add the chopped yellow onion to the skillet with the sausage grease and sauté until softened and translucent, about 5-7 minutes.
- Combine Ingredients: In a very large mixing bowl, combine the cooked sausage and sautéed onions. Add the entire bag of frozen diced hash browns to the bowl. Stir gently to distribute the sausage, onions, and potatoes evenly.
- Mix Eggs and Milk: In a separate medium mixing bowl, whisk together the 7 large eggs, 1/2 cup milk, salt, and pepper until well combined and slightly frothy. Ensure the seasonings are fully incorporated.
- Assemble Casserole: Pour the egg mixture over the hash brown, sausage, and onion mixture in the large bowl. Add about three-quarters of the grated mild cheddar cheese to this mixture. Gently fold everything together until all ingredients are evenly coated with the egg mixture and cheese.
- Pour into Dish: Carefully pour the entire mixture into your prepared 9×13-inch casserole dish, spreading it out evenly with a spoon or spatula.
- Bake Initial Stage: Place the casserole dish in the preheated oven. Bake for 35 minutes. At this point, the casserole should be mostly set around the edges but still a little soft in the center.
- Add Remaining Cheese: Remove the casserole from the oven. Sprinkle the reserved approximately one cup of grated mild cheddar cheese evenly over the top of the partially baked casserole.
- Continue Baking: Return the casserole to the oven for another 8-10 minutes, or until the cheese is melted and bubbly and the casserole is golden brown around the edges. The eggs should be fully set in the center.
- Rest and Serve: Allow the baked Cheesy Potato Breakfast Casserole to rest on a wire rack for 15-20 minutes before slicing and serving. This resting period helps the casserole set, making it easier to cut and serve cleanly. Enjoy!
Pro Tips & Troubleshooting
Ensure your Cheesy Potato Breakfast Casserole turns out perfect every time with these helpful tips. Avoid common issues and achieve a delightfully set and flavorful dish.
- Prevent Watery Casserole: Do not thaw your hash browns beforehand. Thawing releases excess moisture, which can make your casserole watery. Cook your sausage thoroughly and drain most of the grease.
- Ensure Potatoes are Cooked: Use frozen diced hash browns, not shredded. Diced potatoes cook more evenly. If using fresh, par-boil them slightly before adding.
- Achieve Perfect Egg Texture: Avoid over-baking. Eggs can become rubbery if cooked too long. The casserole is done when the center is set and the top is golden.
- Tips for Even Baking: Press the mixture down gently and evenly into the casserole dish before baking. This helps ensure all components cook at the same rate.
- Make-Ahead Best Practices: Assemble the casserole the night before, cover tightly with foil, and refrigerate. Add an extra 10-15 minutes to the baking time if baking directly from the fridge.
The USDA provides valuable information on food safety for make-ahead meals.
Serving, Storage, and Variations
Make the most of your Cheesy Potato Breakfast Casserole with these serving and storage suggestions. You can also easily adapt this recipe with various additions to keep things exciting.
- Best Serving Suggestions: Serve warm with a side of fresh fruit, a dollop of sour cream, or a sprinkle of fresh chives. Ketchup or hot sauce are popular condiments.
- Proper Cooling and Storage: Let the casserole cool completely before covering tightly with plastic wrap or aluminum foil. Refrigerate within two hours of baking. It keeps well for up to 3-4 days.
- Reheating Instructions: Reheat individual portions in the microwave until warmed through. For larger portions, cover with foil and reheat in a 300°F (150°C) oven until hot, about 15-20 minutes.
- Freezing Cooked Casserole: Fully cooked and cooled casserole freezes beautifully. Wrap individual slices or the whole casserole tightly in plastic wrap, then in foil. Freeze for up to 3 months. Thaw overnight in the fridge before reheating.
- Meat-Free Options: Omit the sausage entirely for a vegetarian version. Add more vegetables like diced bell peppers, spinach, or mushrooms for extra flavor and substance.
- Add Different Vegetables: Enhance your breakfast casserole with sautéed mushrooms, bell peppers, or even roasted sweet potatoes. Incorporate fresh spinach during the last few minutes of baking.
- Spice Level Adjustments: Add a pinch of red pepper flakes to the egg mixture for a subtle kick. A dash of smoked paprika also adds a wonderful depth of flavor.
