Pro Tips for the Perfect Christmas Breakfast Casserole
- Use Thawed Hash Browns: Make sure your hash browns are fully thawed so they bake evenly and don’t water down the casserole.
- Prep Ahead: You can assemble everything the night before and refrigerate it. Bake in the morning while you enjoy coffee and unwrap gifts.
- Let It Rest: After baking, let the casserole cool for 10 minutes to firm up before slicing.
- Spice It Up: Add a pinch of cayenne or a few dashes of hot sauce if your family loves a little heat.
- Make It Yours: Feel free to swap the sausage for bacon, ham, or a vegetarian alternative. Cheddar is classic, but other cheeses like mozzarella or pepper jack work great too.

With layers of flavor and a golden, cheesy finish, this Christmas Breakfast Casserole is everything you need to make the holiday morning feel extra special.
Ingredients:
- 1 pound breakfast sausage
- 1 tablespoon olive oil
- 1 small onion, finely chopped
- 1 red bell pepper, diced
- 1 green bell pepper, diced
- 3 cups frozen hash brown potatoes, thawed
- 8 large eggs
- 1 cup whole milk
- 1 teaspoon salt
- ½ teaspoon black pepper
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- ¼ teaspoon paprika
- 2 cups shredded cheddar cheese
- ¼ cup chopped fresh parsley (optional)
Directions:
- Preheat and Grease: Preheat your oven to 350°F. Lightly grease a 9x13-inch baking dish with butter or non-stick spray to prevent sticking.
- Cook the Sausage: In a large skillet over medium heat, cook the sausage until browned and fully cooked. Break it up into small crumbles as it cooks. Transfer to a paper towel-lined plate to drain any extra grease.
- Sauté the Veggies: In the same skillet, add olive oil and sauté the chopped onion and both bell peppers. Cook for about 5 minutes, or until soft and fragrant. Set aside to cool slightly.
- Whisk the Eggs: In a large mixing bowl, whisk together the eggs, milk, salt, black pepper, garlic powder, onion powder, and paprika until well blended.
- Layer the Casserole: Spread the thawed hash browns evenly in the prepared baking dish. Top with the cooked sausage, then layer the sautéed vegetables over it.
- Add the Egg Mixture: Pour the seasoned egg mixture over the layers. Gently shake the dish or press down lightly to help the liquid settle into all the corners.
- Top with Cheese: Sprinkle shredded cheddar cheese evenly over the top. For a festive touch, you can also add chopped parsley.
- Bake Until Golden: Bake uncovered for 45 to 50 minutes, or until the eggs are set and the top is golden brown. A knife inserted in the center should come out clean.
- Cool and Serve: Let the casserole rest for 10 minutes before cutting into squares. This helps the pieces hold their shape and makes serving easier.
