Keto Alfredo Sauce Recipe – Keto Mamas

Keto Alfredo sauce - Alfredo sauce over a bed of spiralized zucchini

This keto Alfredo sauce recipe is so delicious.  The Alfredo sauce is a wonderful and healthy keto meal.  The keto Alfredo sauce is rich and creamy just as though you ordered it from your favorite Italian restaurant.  Put it over a bed of zoodles (spiralized zucchini noodles) and you will find that the zoodles feel better for you than the traditional pasta noodle that sits in your stomach like a brick and makes you feel heavy and sluggish.  I think it is amazing!  You can enjoy the satisfying, buttery and cheesy flavors of the Alfredo sauce and still feel like you ate a light and healthy meal.  Add a delicious side salad with avocado oil and vinegar and your meal is complete.

Alfredo Sauce Variations:

Add chicken, shrimp or ham.  I used Teton Waters 100% grass-fed beef, jalapeno-cheddar bratwurst from Costco in this photo.

Substitute Pastas:

Cut Spaghetti squash in half long ways, remove seeds and bake at 350 degrees for 75 mins or until a fork goes through skin easily.  Scrape out the squash from the skin and use as pasta. Top with alfredo sauce.

After spiralizing zucchini (I use the Briefton spiralizer), boil in water for 3 to 4 mins. Strain off water and serve as pasta.  Top with alfredo sauce.
