Fettucine Alfredo is one of the most beloved comfort food dishes in America, but it’s not exactly compatible with most diets (other than maybe carb-loading before a marathon). That’s what inspired us to make a version that is compliant with vegan, gluten-free, low-carb, and keto diets. Our zucchini noodles are coated in a rich, macadamia-nut-based Alfredo that is whirled together in a blender with minimal ingredients. You’ll find it tastes cheesy and fills you up for hours.

While you may have seen a lot of cashew cream sauces on Pinterest, we opted for macadamia nuts because they’re low in carbs (1.2 net grams per ounce). This particular recipe will only set you back roughly 11.4 net grams of carbs per serving, well within your allotted 50 grams for the day.
