Alfredo Sauce Recipe: Low Carb Authentic Italian Goodness

Any authentic Alfredo sauce recipe is always low carb. It’s a simple sauce made with just 5 ingredients. It’s absolutely delicious on chicken and I like it on cauliflower and broccoli, as well. While this low carb Alfredo goes together really fast, you can store it in the fridge for about a week. That way you can pour it over anything you want.

For this recipe you’ll need: heavy cream, Parmesan cheese, butter, whole nutmeg, kosher salt

I didn’t realize I hadn’t posted my Alfredo recipe. I just kind of assumed I had because it’s so basic. You’re going to love this. The hardest part of this recipe is having the patience to melt the butter slowly!

There are no substitutions. You have to use heavy cream, you have to use real butter, and you have to use the shredded kind of fresh Parmesan. The key to a really awesome Alfredo is fresh ingredients that’s why I use whole nutmeg. It’s easy to grate and the flavor is SO much better. You just need a pinch, literally just a pinch, in this or else it’s overkill. All of the flavors in this sauce are delicate and balanced — it’s quite a change if you’ve only been used to commercial sauces.

The butter needs to be melted very slowly and never allowed to boil up. If it separates the sauce will be greasy and separated. In fact, all the way through this you want the ingredients to heat gently. Once the butter is completely melted you pour in the cream slowly, whisking the whole time. After a minute or two it will thicken slightly but it doesn’t really thicken up until you add the cheese.

And I’ll be honest. This isn’t a pasty, thick, gloppy sauce.

If you don’t eat it all in one meal you can add the remaining sauce to a jar and cover it tightly. It will stay good in the fridge for a week. It will get thick when it’s cold but it will be fine if you heat it up slowly.

Whole nutmeg has so much more flavor than ground nutmeg. It adds a warm, almost peppery flavor to all kinds of things. In this Alfredo the nutmeg adds a “wow, what’s in this sauce?!” kind of vibe. A special nutmeg grater is nice to have. It creates a finer grind than most graters.

    • I just divided up the recipe I didn’t measure it out per serving. I’d say about 1/4 cup per serving, though.

    • I hope you liked it Dotty!

    Just finished making this sauce! Poured it over shrimp and spaghetti squash…absolutely delicious! Thank you!

    • I’m glad you liked it Nicole! Thanks for letting me know~!

  6. Can ghee be used in place of the unsalted stick butter?

    • I don’t think so? But I haven’t tried.

    • I just made it tonight with ghee and OMG it was good! Will probably be richer and you don’t have to worry about it burning because of the higher melt temp! Excellent and easy recipe! Thank you! Put del month vegetable noodles and chicken breast bites in it!

    My son in laws office staff decided to go keto, along with myself, so they designated me lunchtime chef as I don’t work. Out of all the meals I’ve served them the past 2 weeks I think this has been the favorite. I doubled the alfredo sauce and served it over a mix of chicken breast cubes, sauteed green beans, zucchini, mushrooms and sweet yellow onion. My daughter had returned to the office after lunch and said “Mom, all that was left in the bowl were 2 pieces of chicken and a tablespoon of sauce! I tried the sauce and it was delicious.” I told her I saved some sauce for her at home. 😉 I will definitely be making this again. I’ve made alfredo many times over the years, but this was exceptionally good. Thank you for sharing!

    • Thank you! SO glad they liked it!

    This sauce is so good! When I was making it I followed the directions perfectly however the cheese would not melt completely and therefore the sauce wouldn’t thicken. Lesson learned I won’t buy that cheese again but I salvaged it by adding xanthan gum. My boyfriend just said this is delicious!

    • Yeah – the cheese is important!
