It’s about time I share an overnight breakfast casserole around here! With two little kids, I find myself at a bit of a loss for what to serve for brunch; waffles and pancakes are popular but require so much effort in the morning.

How to make breakfast casserole the night before

Prepping this breakfast casserole the night before makes it so hands off the next morning, which leaves you free to hang out with your guests rather than being stuck in the kitchen!

• • cook the bacon, chop the veggies and shred the cheese
  • assemble in a deep casserole dish (I use this one from Crate & Barrel); pour the egg over everything and mix it all up
  • cover with plastic wrap and refrigerate overnight
  • in the morning remove from the fridge and allow to stand at room temperature while the oven pre-heats
  • bake it up!

You could make this breakfast casserole as a meal prep breakfast as well; the leftovers are great for a breakfast or lunch, and they even freeze well!

How to freeze this breakfast casserole

1. in individual portions: After baking, cool and portion out the breakfast casserole. Wrap with plastic wrap and store in a large freezer bag or individual container. Thaw completely, then heat in the microwave. You may wish to heat on a paper towel to absorb any extra moisture that can leak out during the freeze/thaw process.
2. whole casserole: Cool completely, then cover with plastic wrap and foil. Freeze up to 3 months. Thaw completely and re-heat (covered with foil but not plastic wrap) at 350°F for 30-40 minutes or until warmed through in the center.

Depending on the dish you use to bake this overnight breakfast casserole, you may need to alter the bake time slightly. You will know it’s baked through when the center rises slightly and no longer jiggles.

I also double checked by inserting a knife in the middle and making sure there wasn’t any liquid oozing around.

This overnight breakfast casserole is totally easy to switch up

• you can leave out the sweet potatoes for an even lower carb version
• mushrooms, asparagus, spinach, even broccoli (chopped very small) would be great in this casserole!
• swap the bacon for sausage or leave it out all together
• make it paleo by using almond milk and leaving out the cheese…you still get a ton of flavor from the bacon, jalapeno and sweet potato
