Step-by-Step Instructions
- Preheat Oven and Prepare Casserole Dish: Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish with butter or cooking spray to prevent sticking.
- Layer the Potatoes: Arrange about half of the thinly sliced Yukon Gold potatoes in an even layer on the bottom of the prepared baking dish. Overlap them slightly to ensure complete coverage.
- Add Sausage, Onion, and Pepper: Sprinkle the crumbled cooked breakfast sausage evenly over the potato layer. Next, scatter the finely chopped yellow onion and green bell pepper over the sausage.
- Add Remaining Potatoes: Place the remaining thinly sliced potatoes in a second even layer on top of the sausage and vegetable mixture.
- Prepare the Egg Mixture: In a medium bowl, whisk together the large eggs, milk, salt, black pepper, garlic powder, and paprika until well combined and slightly frothy.
- Add Cheese to Egg Mixture: Stir in 1 ½ cups of the shredded cheddar cheese and all of the shredded Monterey Jack cheese into the egg mixture. Reserve the remaining ½ cup of cheddar cheese for topping.
- Pour Egg Mixture Over Casserole: Carefully and evenly pour the egg and cheese mixture over the layered potatoes, sausage, onion, and pepper. Ensure the liquid seeps down into all the layers.
- Top with Remaining Cheese: Sprinkle the reserved ½ cup of shredded cheddar cheese evenly over the top of the casserole, creating a beautiful golden crust as it bakes.
- Bake the Casserole: Cover the baking dish loosely with aluminum foil. Bake in the preheated oven for 35 minutes.
- Brown the Top: Remove the aluminum foil and continue to bake for another 10-15 minutes, or until the potatoes are tender when pierced with a fork, the casserole is set in the center, and the cheese on top is bubbly and golden brown.
- Rest Before Serving: Let the Cheesy Breakfast Potato Casserole rest for 5-10 minutes after removing it from the oven before slicing and serving. This allows the casserole to set slightly, making it easier to cut.
