My husband is an absolute nut for breakfast foods.

I mean, I eat a little breakfast each day. Sometimes an avocado drizzled with Cholula. Sometimes a scrambled egg. Sometimes I just drink my coffee and call it good.

I think the avocado with Cholula is my favorite low carb breakfast of all time, though. It’s so good!

Anyway, I’m getting off track!

I eat a super simple breakfast through the week, but on the weekends the husband is home and he wants a MEAL.


He’s happy to cook it himself, but I like to play the loving wife and make him bacon and eggs and all the other good breakfast food most days.

But, I also like to sleep in and be super lazy, sooooo that’s where this easy breakfast casserole comes into play.We love this make ahead breakfast casserole! It's naturally low carb and packed with bacon and sausage.

Make Ahead Breakfast Casserole:

This easy breakfast casserole can be made in advance.

Prepare, bake, and refrigerate until ready to serve.

Just pop individual servings in the microwave to reheat. It’s even good cold, if you ask me.

Obviously, this means that it makes a fabulous holiday recipe. You know when you have a million people staying at your house over the holidays and you’re just like…ugh. You want me to cook for you AGAIN?

This is perfect for that feeling.

Low Carb Breakfast Casserole:

I keep it low carb by cutting any sort of starchy veggies or bread and just sticking to the good stuff: eggs, meat, and cheese!

I’ve used sausage and bacon today, but ham is tasty too! Who doesn’t love pork in the morning?

For more low carb favorites, try my stuffed peppers or this chicken casserole. My egg roll in a bowl is a reader favorite, too.

This breakfast casserole with bacon is a total hit with my family.

Bacon is a must, obviously, but I also added a few veggies.

Onion and bell pepper are perfect here, but you can definitely get creative here and stir in other veggies. Jalapeno would be really good if you like spice!

Everything just gets stirred together with a bunch of grated cheese. I use cheddar, but you can use whatever variety you like.

If you’re not watching carbs, this is another of my favorite breakfast casserole recipes.
