What you’ll need to make it
- 1 pound breakfast sausage, casings removed
- 6 large eggs
- 2 cups milk
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 4 cups frozen hash browns, thawed
- 2 cups shredded cheddar cheese
- 1/2 cup chopped green onions
- 1/2 cup diced bell pepper
Step-by-step guide to making this Father’s Day Breakfast Casserole
Start by preheating your oven to 350°F (175°C). While the oven heats, cook the breakfast sausage in a large skillet over medium heat, breaking it apart with a spatula until browned and fully cooked.
In a mixing bowl, whisk together the eggs, milk, salt, black pepper, garlic powder, and onion powder until the mixture is smooth. This will form the base for your casserole.
Grease a 9×13 inch baking dish and spread the thawed hash browns evenly across the bottom. Layer the cooked sausage on top of the hash browns, ensuring it’s distributed evenly.
Pour the egg mixture over the sausage and hash browns, making sure everything is well coated. Sprinkle the shredded cheddar cheese over the top, followed by the chopped green onions and diced bell pepper for added color and flavor.
Bake the casserole in the preheated oven for 45-50 minutes, or until the eggs are set and the top is golden brown. Let the dish cool for a few minutes before slicing and serving.

How to store and enjoy leftovers
Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, simply place a portion in the microwave for 1-2 minutes or warm it in the oven at 350°F until heated through.
Common questions about this recipe
Can I prepare this casserole ahead of time? Yes, you can assemble it the night before and refrigerate it. Bake it fresh in the morning.
Can I use fresh hash browns instead of frozen? Absolutely! Just make sure they’re thawed and drained to avoid excess moisture.
Simple ingredient substitutions
If you prefer a milder cheese, swap the cheddar for Monterey Jack or mozzarella. For a vegetarian version, replace the sausage with sautéed mushrooms or plant-based crumbles.
