Much like Classic Eggs Benedict, Biscuits and Gravy Casserole, or Hashbrown Breakfast Casserole, this is the perfect hearty weekend breakfast any time of year, but my family especially loves it on holiday mornings.

This breakfast recipe has it all.

When I think of a comforting, savory, hearty breakfast that will keep you full all day long, it needs to have eggs, meat, cheese, potatoes, and vegetables.

Tater tots are an easy way to enjoy that great hash brown flavor and crisp but in little bite sized pieces.

You can buy breakfast sausage in bulk or you can buy links and remove the sausage from the casings prior to cooking it. You can also buy ground pork and make your own breakfast sausage blend with spices you have in your pantry.

Easy to make ahead of time.

One of the main reasons to make a breakfast casserole, aside from being able to feed a crowd all at the same time, is the ability to prepare it ahead of time.

Weekend breakfasts and holidays are what breakfast casseroles are made for.

To make this breakfast ahead of time, all you need to do is follow the recipe all the way up to the point where the casserole goes into the oven. Cover it and refrigerate.

Then, to bake the next morning, simply allow it to come close to room temperature and bake.
