This Italian inspired keto dinner recipe is easy to prepare and ideal for meal prep. Simply make a batch or two of our Homemade Bolognese Sauce and then serve with zucchini noodles or shirataki noodles.

To keep this meal below 10 grams of net carbs, you need to be careful with the amount of zucchini you'll be using. That's why I'm using a small 150 g/3.5 piece per each serving. If you use shirataki noodles, the carb count will drop even more.

You can keep yours dairy-free although I like to sprinkle a little Parmesan or Pecorino Romano on top. Enjoy!

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.
