Low Carb Fettuccine Noodles

For our Creamy Alfredo Sauce I have picked my Homemade Keto Fettuccine Noodles to make this dish as authentic as possible, but still Keto. Much more details on the noodles themselves are in a separate post if you are interested to read and learn.

Make your own Low Carb Pasta

But in case you would like to explore a bit more on homemade pasta recipes, I would suggest looking at our Homemade Keto Egg Noodles made with Almond Flour, Fiber Noodles using either Potato Fiber or Oat Fiber, Keto Spaghetti made with Bamboo Fiber or a Low Carb Pasta made with Psyllium Fiber. Or go even further and enjoy our Homemade Keto Gnocchi everyone is raving of. 

When I read those lines above, I can not believe how many options we have and I have made for you to choose from.

What Keto Pasta can you use with Alfredo Sauce?

If you are not ready to make your own noodles, just pop into our Post of various Keto and Low Carb Pasta and Noodles Variations you can have. From Shirataki, Palmini Noodles, Zoodles, Spaghetti Squash, and much much more. 

Authentic Alfredo Sauce

With this extra creamy, cheesy, and super-rich Italian Alfredo Sauce, I wanted to get into as much authenticity as possible. 

Using Parmesan cheese, garlic and butter was a must. And as those are fully allowed in our lifestyle, this smooth creamy sauce is fully in. 

No need to add any thickening agents as some might, because the parmesan cheese itself will thicken it to the exact texture you need it to be. 

And as a Traditional Italian Recipe calls for fettuccine noodles, which we now have in a Low Carb Fettuccine Version. We are all set and ready to roll. 

Low Carb High Fat

You might have already heard of people following a fully Low Carb and High Fat Diet LCHF in short. 

I am not really a big advocate of this as I believe everything needs to be taken in moderation.

But if you are, this recipe is just the right choice for you.

Our Keto Fettuccine Alfredo Sauce with Homemade Noodles has a whopping 60g of Fat per Portion.

How easy is it to reach your limit with this?

And just in case you will be still missing a few grams of fat in a day, add a few bites of our Cream Cheese Fat Bombs and you are ready to Rock N Roll.

How many Carbs does Fettuccine Alfredo Have?

There are almost no Carbs in Low Carb Alfredo Sauce itself. But if you take our recipe together with Keto Noodles, you do get a mere amount.

The whole recipe together with Noodles can be split into 2 Servings.

1 Serving of this fabulous Keto Meal contains 5g of carbs and 2g of Fiber. Giving you a total of 3 g of net carbs per serving.

How to Thicken Keto Alfredo Sauce?

Using a whole cup of Parmesan Cheese should thicken this sauce greatly. You might not see it at the beginning, but once the sauce cools down, the whole thickening process multiplies.

If you’re still not satisfied with the thickness you can use the following options to thicken the sauce a bit more:

Add extra grated Parmesan Cheese
Use Xanthan Gum, but really only a tiny pinch of it, otherwise your sauce will transform onto gooeyness
Adding a few teaspoons of Gelatine does the trick of thickening any of the low-carb sauces as well. 

Alfredo Sauce Variations and Additions

Before I go fully to our Quick and Easy almost Authentic Italian Alfredo Sauce Recipe, I would like to give you some suggestions on ways to use Alfredo Sauce as well as different variations you can make with it.

Apart from using this Creamy Garlic Sauce on Noodles, you can pick from various suggestions to make low carb recipes:

  • Add Chicken to make Keto Chicken Alfredo
  • Pour the sauce over roasted Asparagus
  • Fe pieces of Shrimps with transforming this to Keto Shrimp Alfredo

Tips and Tricks

Heavy Cream – Should be at room temperature to prevent separation while cooking

Parmesan Cheese – grate it yourselves as already pre-shredded cheese from the market contains always some kind of starch to keep the cheese separate and will add necessary carbs into your meal

Extra Smooth Alfredo Sauce – place the sauce into your blender before serving for that extra smooth creaminess

FREQUENTLY ASKED QUESTIONS AND ANSWERS

How do you store Alfredo Sauce?

To store Alfredo Sauce is the best on its own without any noodles. Place the sauce into the Mason Jars or a Glass Container and store in the fridge for up to a week. 

Can you freeze Alfredo Sauce?

You can certainly freeze Alfredo Sauce in the freezer.

Again, I would suggest freezing the sauce separately without any keto noodles or pasta. 

Once ready to consume, take it out of the freezer the night before and let it thaw naturally in the fridge.
