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!
