I'm the only one in our family that is following a low carb diet. And although there are some dishes that are suitable for everyone, I often have to cook variations so that all are satisfied. A cooked breakfast or brunch, however, is rather a different matter. I decided to make this low carb breakfast casserole for the whole family to enjoy. It's filling, warming, and nutritious - with a great combination of egg, sausage and cheese. I also added in some healthy baby spinach and mushrooms which I knew my family would appreciate.
The heart of this breakfast casserole is the Founder's Select Pre-Cooked Polish Sausage from Klement's. The range of premium meat products from this 60 year old company includes summer sausages, snack sticks, fresh sausages, cocktail smokies, ring bologna and more, and I just love how these handcrafted artisan products also happen to be low carb!
I've used this sausage before when I made my One Pan Sausage and Shrimp tray bake - they are so handy because they are pre-cooked and impart so much flavor to the dish. They are also available in other varieties: Italian, Jalapeno, Cheddar, Bratwurst, Chorizo, Smoked Bratwurst or Bacon Cheddar Bratwurst, but I think that the Polish version works best for this meal.

How to Make a Low Carb Breakfast Casserole
To prepare the casserole, heat some butter and olive oil in a large skillet and sauté some sliced mushrooms until soft.
Add in some baby spinach and let it cook until wilted. Transfer the veggies to a baking dish. Thinly slice the Polish Sausage - I used a whole pack of five as we love protein in our house!
Using the same skillet, lightly cook the sausage for around five minutes - and if the smell of mushrooms frying in butter didn't get your family into the kitchen to see what was cooking, the smell of this sausage definitely will!
Add the sausage to the baking dish.
Whisk together eggs, heavy cream, shredded mozzarella cheese, salt and pepper.
Pour the mixture over the sausages.
Cover and bake in a preheated oven for 15 minutes, then sprinkle over more cheese, and bake for another 15 minutes uncovered. Serve to your family, and enjoy!

No I haven't, but I bet it would work well! Let me know if you try it!

Sounds delish! What size casserole and approximately how many does this feed? Thanks!

Hi Paco, It serves 6, and the casserole dish is 3 quart. Enjoy!
Kathy says
Can you put this together the night before thenbin the oven the next morning?
Georgina says
Ooooh that's a good idea! I haven't tried it but I can't think why it wouldn't work. If you try it, let me know!
Tera says
Did you try making it ahead of time? I'm looking for a Christmas Day recipe and all the others I've viewed are make ahead recipes! Was going to try this for tomorrow! I think I'll cook the sausage and prep it all even mix the eggs and milk in a dish, shred cheese but completely assemble in the morning! Unless it's been tried tested and true lol,
Joni says
I made a version of this this morning, was so good. I didn't have any spinach or sausage, so I used green onions, red peppers and ham instead. Definitely a keeper recipe! Thank you.
Georgina says
Thanks for the great feedback!
Tyrell says
Could I use breakfast sausage instead of sausage links?
Georgina says
Absolutely - just check the carb count and get as close to zero as you can!
Laura Robinson says
Would you use a 9X13 casserole dish for this?
Georgina says
I just went and measured the one I used in the photos. It's approximately 9x11" and oval. So a rectangular 9x13 might be a little too big - but if that's all you have try it and let me know how it turns out!
