- 1 package (30 oz) frozen shredded hash browns, thawed

- 1/2 tsp salt
- 1/4 tsp black pepper

Step-by-Step Instructions to Make Cheesy Christmas Breakfast Casserole
- Preheat and Prepare: Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or nonstick cooking spray.
- Brown the Sausage and Veggies: In a large skillet over medium heat, cook the ground sausage for 5 to 6 minutes, breaking it into small crumbles. Add the diced onion, red bell pepper, and green bell pepper. Sauté for another 4 to 5 minutes until the sausage is browned and the veggies are tender. Drain any excess fat.
- Layer the Casserole: Spread the thawed hash browns evenly across the bottom of the prepared baking dish. Top with the cooked sausage and vegetable mixture, then sprinkle half of the shredded cheese over the top.
- Whisk the Egg Mixture: In a large bowl, whisk together the eggs, milk (or heavy cream), garlic powder, onion powder, salt, and black pepper until fully combined and smooth.
- Pour and Top with Cheese: Pour the egg mixture evenly over the hash brown and sausage layers in the baking dish. Top with the remaining shredded cheddar and Monterey Jack cheese.
- Bake to Golden Perfection: Bake uncovered at 375°F for 40 to 45 minutes, or until the center is set and the cheese on top is golden brown and bubbly.
- Cool and Serve: Let the Cheesy Christmas Breakfast Casserole cool for 10 minutes before slicing. Garnish with chopped fresh parsley or chives and serve warm!
Expert Tips and Variations for Cheesy Christmas Breakfast Casserole
- Overnight Option: Assemble the entire dish on Christmas Eve, cover tightly with foil, and store in the refrigerator overnight. In the morning, bake at 375°F for 50 to 55 minutes (adding 10 extra minutes since it starts cold from the fridge).
- Meat Alternatives: Swap the sausage for diced ham, crisp bacon, or plant-based breakfast crumbles.
- Bread Swap: Replace the hash browns with 6 cups of cubed French bread or croissants for a strata-style breakfast bake.
