Keto Alfredo Sauce Recipe 

This recipe for alfredo sauce is completely keto-friendly. You can pour it over some nice zucchini noodles or butternut squash noodles rather than traditional pasta to keep this as a delicious keto recipe. You really don’t even need traditional pasta noodles when you have tasty and much healthier alternatives like zucchini noodles.  A big problem with regular flour pasta noodles is that it won’t affect your blood sugars right away, but there is a delayed response. You might test your blood sugars and think that it’s fine to consume regular pasta, but then a few hours later, your blood sugar spikes. Traditional pasta noodles are definitely not good for weight loss either, but with veggie noodles, you’re good to go. You could also add meat, shellfish, or bacon to this recipe for a little something extra.  Even a lot of sauces have hidden sugar or carbohydrates, but not this one. Alfredo sauce happens to be Karen’s all-time favorite pasta topping, and we think you’re going to love this recipe too!
