How To Make Easiest Hashbrown Breakfast Casserole
Preheat your oven to 350°F and prepare a 9×13-inch baking dish by coating it with non-stick cooking spray.
In a medium bowl, whisk together the eggs, milk, salt, pepper, and dried minced onion until well combined and slightly frothy. Set aside.
In the baking dish, layer the shredded hashbrowns evenly across the bottom. Then sprinkle the turkey sausage crumbles and bacon pieces over the hashbrowns.
Top the meat with shredded cheddar cheese, spreading it evenly over the entire dish.
Pour the egg mixture evenly over the layered ingredients, making sure everything is moistened and covered.
Carefully place the dish in the center of your preheated oven. Bake for 38 to 42 minutes, or until the casserole is set and the cheese on top is melted and slightly browned around the edges.
Remove from oven and let it cool for 5 minutes before slicing and serving. Enjoy warm.

Notes
What type of milk should I use in a breakfast casserole? I used 2% milk in this casserole, but feel free to use whole, skim, or for a dairy free breakfast casserole use a plain oat or coconut milk with vegan cheese.
Suggested options: Top with some green chives, fresh diced tomatoes or sour cream. Serve with some fresh fruit and whole wheat toast for a well-rounded breakfast.
