Keto Alfredo Sauce
While you may be able to find canned or jarred alfredo sauce that is relatively low in carbs, you can usually lower the carb count even more by making it at home. There’s nothing wrong with jarred alfredo, but many
Keto alfredo sauce makes a great addition to zucchini noodles, sliced veggies, or served with your protein of choice. Pair it with shrimp, chicken, or even a white keto lasagna. It’s an awesome low carb condiment to complement a variety of dishes. And since you are dropping the carbs low, you can typically afford the higher fat content in your daily energy budget. Cool, right?
Alfredo Sauce Carbs: Low Carb Alfredo Sauce
If you’re on the hunt for a low carb alfredo sauce, you may be wondering what the carbs in alfredo sauce add up to.
In our homemade keto alfredo sauce recipe, there are only 2.8g of total carbs per ¼ cup serving. Not too shabby!
What is Keto Alfredo Sauce Made Of?
Instead of traditional milk and flour, the alfredo sauce contains butter, heavy cream, mascarpone, garlic, basil, oregano, parsley, and Parmesan cheese to reduce carbs. If you don’t have mascarpone on hand, you can substitute with cream cheese. Alternatively, you can simply leave the ingredient out, but it acts as one of the primary thickeners in our recipe.
How Can I Thicken Alfredo Sauce Without Flour?
If you aren’t using flour or cornstarch, how can you thicken keto alfredo sauce? Cheese! Mascarpone, cream cheese, parmesan--these will all thicken it right up! Since we are using butter and heavy cream, the sauce is already much thicker without any of the extra additions.
Alternative low carb thickeners include coconut flour, xantham gum, or guar gum. Just be careful using these ingredients to thicken sauces! While they are all low in carbs, a little goes a long way. Adding too much coconut flour will dry things out and result in a clumpy texture, while the gums can become rubbery and sticky in excess. Little by little is the name of the game with these types of ingredients.
How to Store Sauce
One of the great things about this recipe is that you can store the leftovers for later! To store the keto alfredo sauce, seal it in an airtight container in the refrigerator for up to one week.
How to Reheat Keto Alfredo Sauce
To reheat leftover alfredo sauce, you can zap it in the microwave in a microwave-safe container or use the stovetop. In the microwave, reheat in 30-second intervals, stirring in between until it reaches the desired temperature and consistency. On the stove, simply place in a saucepan over low-medium heat and stir until the alfredo sauce comes back to life.
If the keto alfredo sauce seems too thick once it has heated, stir in a small amount of water, cream, or broth to thin it out. It may take several minutes to rejuvenate the sauce with heat, as some of the core ingredients solidify when refrigerated.
How to Make Keto Chicken Alfredo
A great chicken alfredo begins with the keto alfredo sauce, and we’ve certainly covered those bases. But what can you use in place of fettuccine noodles? Great question!
Zucchini noodles, or any other keto vegetables cut into thin ribbons, can be a great replacement to make keto chicken alfredo. A spiralizer tool makes the process effortless!
Another great low carb alternative to consider using is shirataki noodles. These are translucent noodles made of konjac and packed in water. They are mostly flavorless when rinsed, taking on the flavors they are cooked in. They come in different shapes as well to mimic the look and texture of the noodles we are used to cooking with--spaghetti, fettuccine, etc.
Shirataki noodles are a popular option for keto dieters since they have zero net carbs. Remember, net carbs = total carbs - fiber. Net carbs are the ones that directly impact metabolism and ketosis. As shirataki noodles are made almost entirely of fiber, they don’t affect nutritional ketosis. That also means they are low in calories and can be great for people on a weight loss mission.
There are a variety of brands available, including Miracle Noodle, Nasoya Pasta Zero, and Organic Well Lean. While the Nasoya Pasta Zero shirataki noodles can be easily found at local grocery stores like Safeway, Miracle Noodles and Organic Well Lean are typically only ordered online through specialty stores or on Amazon.
Tools to Make Alfredo
Whisk: The whisk is an absolute necessity--arguably the most important tool for making your own keto alfredo sauce! Honestly, you don’t need anything fancy, just a simple whisk will do. It helps breakdown and evenly distribute the ingredients and is especially helpful when working with cheese-based sauces.
Saucepan: You really can’t beat a saucepan when it comes to making homemade sauce. It’s just the perfect size and depth to whip up a batch of keto alfredo! And a saucepan with a pour spout makes it easy to transfer the sauce to your plate or sauce jar.
Sauce Jar: Wide-mouth mason jars are perfect for sauce storage in the fridge and freezer. Storing in glass allows for safe reheating in the container and the wide-mouth opening makes it easy to scoop out the sauce. Jars are also perfect for drizzling sauce over keto chicken alfredo.

Hi, I'm Tasha–nutritionist, recipe developer, and multi-published cookbook author.
This was the best alfredo I've ever had. Italian sausage, broccoli and served over a bed of Palmini noodles. Definitely once a week for this one. Thank you Tasha.
