If you’re not familiar with alfredo sauce, it’s a white sauce that is served with pasta. Since the keto diet doesn’t allow for wheat-based pasta, you have the option of serving this with keto-approved pasta alternatives like shirataki noodles, spaghetti squash or zucchini noodles.

What Makes Alfredo Sauce Such a Popular Choice for Low Carb Diets?

It’s no secret that alfredo sauce is wildly popular. So with that in mind, let’s look at three of the main reasons why it’s become so popular with low carb dieters in particular:

• Alfredo sauce is a delicious pasta sauce that’s typically made with a variety of low carb ingredients like cream cheese, heavy cream, garlic, and Parmesan cheese.
• It’s an excellent source of both saturated fat and protein, the two main macros that low carb dieters are looking for.
• Alfredo sauce is super easy to incorporate into a ton of keto pasta recipes.

Is Alfredo Sauce Keto?

Since alfredo sauce is typically made with ingredients that are keto staples (heavy cream, cheese, garlic, etc.), it’s incredibly easy to incorporate it into a variety of different low carb pasta dishes. And since it uses so many keto staples, you can rest assured knowing that alfredo sauce will provide you with plenty of both protein and dietary fat.

All in all, alfredo sauce is an easy recommendation to make for any and all keto dieters who love pasta.

What Makes This Homemade Keto-friendly Alfredo Sauce So Healthy?

Besides the fact that it tastes fantastic, there are a few more reasons why you should consider making your own keto alfredo sauce with this recipe:

• Relieves inflammation. Chronic inflammation in the body can lead to the development of numerous types of diseases. (1) Foods like garlic are high in anti-inflammatory compounds that help to relieve inflammation within the body.
• Provides antioxidants. Garlic and parsley are both rich in disease-fighting antioxidants that help to protect against the damage caused by harmful free radicals.
• High quality fats. This recipe uses both butter and heavy cream, both of which provide you with a solid amount of high quality saturated fats. Bonus points if you use grass-fed butter, which contains higher amounts of omega-3 fatty acids, vitamin E, and other antioxidants. (2)

How to Store Homemade Alfredo Sauce

Depending on how long you want to hold onto your leftover alfredo sauce, you can either freeze or refrigerate it. Whatever you decide on, the most important thing to do with either option is to allow the keto alfredo sauce to cool completely first.

Once it has cooled off, store the sauce in an airtight container or a mason jar to either refrigerate or freeze.

For best results, I would recommend keeping it in the fridge and trying to consume it before it goes bad (3-5 days due to the heavy cream content). If you decide to freeze it, be prepared to risk losing some texture and consistency when you thaw it out (once again, due to the heavy cream).

Why is My Alfredo Sauce Lumpy?

Make sure to constantly stir your sauce as it cooks. If you leave it, it’s likely to curdle, which is what causes that lumpy texture. Alfredo sauce should be smooth like cream.
