This Quick and Easy Make-Ahead Breakfast Casserole is a delicious freezer-friendly recipe to keep on hand for busy mornings!

So I have a strange obsession with food documentaries. From Fat, Sick and Nearly Dead, to Fed Up … I’ve seen them all if they’re on Netflix. Most recently, I watched That Sugar Film (free on Amazon Prime), and it totally changed the way I look at food.
Well, I’ve always been pro fat and anti sugar, but this documentary totally confirmed that our country has a serious addiction. It made me never want to touch sugar again … until I saw a donut … then I changed my mind.
This Quick and Easy Make-Ahead Breakfast Casserole is so great because it can be made ahead of time and frozen for up to 3 months. That means you can make it on a Sunday when you’ve got nothing better to do, then all that’s left is letting it thaw when you’re ready to bake!
Breakfast casserole is a great recipe to make for feeding a crowd, or if you want to have breakfast for the entire week! With hash browns, sausage, red pepper and onion, this breakfast bake is a true crowd pleaser.
What’s even better is that you can adjust the recipe to fit your taste! Obsessed with bacon? Use that! Prefer mushrooms? Throw them in. The possibilities are literally endless.
I also love adding taco seasoning to my Quick and Easy Make-Ahead Breakfast Casserole, but a simple mixture of salt and pepper will do if you like to keep it classic.

Next time you need a super simple breakfast recipe to make, try this Quick and Easy Make-Ahead Breakfast Casserole! Always keep one of these in your freezer … because you never know when you’re going to need a quality breakfast on the fly.
This really is one of those recipes you keep in your repertoire for mornings full of hungry people.
