How to make overnight Breakfast Casserole

You can easily turn this into a heartier dish by adding in bread cubes. Follow these simple steps:

  • Prepare the bread cubes: Cut slices of bread into cubes the night before and refrigerate them. Drying them out in the oven works, too.
  • Make the wet mixture: Use the same egg and sausage mixtures in this recipe.
  • Assemble: Combine the mixtures and fold in the bread cubes. Pour evenly on the pan, and then, cover and refrigerate overnight.
  • Bake: The next day, the bread must have soaked up all the moisture and it is then ready for baking. Let it sit at room temperature first for a few minutes before baking. It will take longer to bake than when there is no bread added.
  • Serve: Garnish and serve as usual.

What can I add to Breakfast Casserole:

This recipe is highly versatile, and you can mix in any vegetables or meat that you want. Add in ham, ground beef, or even leftover rotisserie chicken and that will be perfect. You can also add in mushrooms, potatoes, or artichokes.

How to Store and Freeze Breakfast Casserole:

  • Refrigerate: You can simply cover leftovers tightly and store them in the fridge for no more than 5 days. Reheat it in the microwave oven.
  • Freeze: Baked or unbaked, this dish can stay good for up to 2 months in the freezer. It is a good make-ahead dish as you can simply thaw overnight and then, bake to cook. Simply cover it with a plastic wrap and another layer of foil.

Recipe Tips:

  • You can leave out any meat and just add more of the veggies.
  • For the meat, the only recommendation is to add it in cooked already just like what we did in this recipe.
  • If you are adding in bread, the best kinds are the stale ones as they are dry already and more effective in soaking up the liquid.
