This is Easy Low Carb Breakfast Casserole is loaded with vegetables and full of flavor. I added sausage and baked until firm. I make this for my father-in-law all the time when they come to visit because he tries to eat a full Keto diet.
A good breakfast to start the day.
Breakfast food is the best, but I'll admit though I'm soooo not a morning person. My kids have learned pretty quickly not to request for mommy until after she has coffee. Do any other moms have the same rule in their house? We all pile on the couch, them with milk and me with coffee, and watch a cartoon, every morning! We all need that minute or two to wake up before starting the day. It's bliss most days, and I enjoy the quiet cuddles. The only issue is on the mornings we have to get going early. They want to sit and relax before fully waking up, but we need to head out the door. Most days though it's wonderful, and I really enjoy an easy breakfast recipe to go along with our slow mornings. Which is why I LOVE low carb-free breakfast recipes like this one. Mix it up and toss it in the oven. Then I can have my cuddle and coffee time with the kids while it bakes.
Making this recipe low carb.
For this recipe, I wanted to keep it low carb so no bread and no potatoes. Just loaded with veggies, some sausage, and eggs all in a baking dish. I topped it with just a little cheese and baked. It takes about 40 minutes to bake so that's 40 minutes of coffee time which I am totally okay with! If you want to try another low carb breakfast recipe you have to try my Muffin Tin Low Carb Breakfast Casserole! I used this recipe but baked them in a muffin tin for easy one serving breakfast.
Want to make this Low Carb Breakfast Casserole ahead of time?
I love making this ahead of time and eating it the next morning or even throughout the week. Since this Low Carb Breakfast Casserole is made with no potatoes or bread it doesn't get soggy overnight. I usually bake it the night before, and then let it cool completely. Cut into slices and place them into an airtight container. If you want to freeze it, I usually cut into squares, and freeze them separately on a baking sheet then add them to a baggy once frozen and keep them in the freezer. This way I can take out just one square at a time!
Reheating this dish:
You can reheat this dish a few different ways. Whether in the microwave or over here is how you would do it.
If you refrigerated the casserole you can reheat it with these directions.
- Microwave - Cut out your serving size and microwave for about 2 minutes. It should come out piping hot, so be careful.
- Oven - If you are using the oven to reheat the whole casserole, preheat the over to 350 degrees. Bake for roughly 10 minutes.
If you froze your casserole you can reheat it best in the oven.
- Thawed - Preheat at 350 degrees and bake for about 15 minutes.
- Frozen - Allow the dish to come to room temperature. Since the pan will be very cold, don't preheat your oven. Turn on to 350 degrees, and place the casserole in the oven then, to warm up with the oven. Bake for about 25 minutes this way.

Hi Kasey! I just updated this recipe with the nutrition facts. I just got the ability to add that in and have been updating recipes but it's not on them all yet.
What size baking dish?
I used an oval oven dish that was 9x12 in these pictures. I have also made this in my standard 9x13 and it comes out perfectly.

I make this all the time. Endless variations. Heats up great for quick meals! I have found about a quarter tsp of baking powder really puffs the eggs up nice and makes them super fluffy!
Thanks for sharing your thoughts on website. Regards
Wonderful recipe that my entire family loves.
can you leave the mixture uncooked in the fridge overnight and bake the next morning?
Hi Caitlin. Yes this can me left in the fridge over night. You would want to sausage to be cooked and cooled then mix it up and cover. Place in the fridge and then into the oven the next morning. Hope you enjoy it!

What are the instructions on reheating after frozen?
If you are reheating from casserole I would allow it to thaw some overnight. Then place it in the oven in the morning to cook. I sometimes will slice it and then reheat each slice. I can do that in the microwave in a damp paper towel to defrost.
My wife and I had this for breakfast and we loved it, making again soon.
Great recipe, I like the tips.
