Pasta. How I miss thee.

I used to joke that I was born in the wrong country, and was sure that I was part Italian. This dish will let you snuggle down with a big cheesy bowl of noodles and eat to your hearts content. You won’t feel stodgy and over loaded like you did after eating pasta, I promise.

What you will feel is ready to go back for seconds. The original Alfredo Sauce recipe was the lowest of low carb sauces EVER.

I don’t know if the Roman restauranteur Alfredo di Lelio, who created it for his pregnant wife, knew that at the time. But excellent work Alfredo.

It consisted of butter and cheese, with a dash of salt. Sadly, it also required fettuccine, but we’ll forgive that. This recipe is a bit different from the original and you won’t find many film stars travelling to my house to eat it, but they would if they had a chance to experience this luscious, yet light version. (If there are any film stars reading this… )

Enjoy!

Ingredients (makes 8 servings)

  • 1.2 kg (2.65 lb) zucchini, spiralised - use 1 small 150 g (5.3 oz) zucchini per serving
  • 4 tbsp extra virgin olive oil (1 tbsp for every 2 zucchini/ servings)
Keto Alfredo Sauce:
  • 2 cloves garlic, minced
  • 3/4 cup unsalted butter (170 g/ 6 oz)
  • 1 1/2 pints heavy cream (700 ml)
  • 6 ounces cream cheese (170 g)
  • 6 ounces Parmesan cheese (170 g)
  • 3/4 cup grated cheddar cheese (85 g/ 3 oz)
  • 1 tsp chopped oregano
  • 1 tbsp chopped basil
  • salt and pepper to taste

Instructions

  1. Prepare the zucchini noodles using a spiraliser. Keto Zucchini Noodle Alfredo
  2. Place the spiralised zucchini into a colander over the sink. Sprinkle with salt and leave to drain. Keto Zucchini Noodle Alfredo
  3. Add the butter to a pan and melt. Add the garlic and cook gently until soft. Add the cream and bring to a simmer. Keto Zucchini Noodle Alfredo
  4. Add the cream cheese and quarter of the shredded cheeses and stir well until the cheese has completely melted.
  5. Keep adding the shredded cheese in batches until it is all melted and you have a smooth, creamy sauce. It will seem like the cheese will never melt. Don’t get panicked and turn up the heat, just keep up the stirring and I promise it will happen.
  6. Add the herbs and mix through. Take sauce off the heat to sit and thicken slightly. Stir every now and then to stop a skin forming. Keto Zucchini Noodle Alfredo
  7. Pat the zoodles dry with a paper towel. Pour your olive oil into a frypan and heat. Toss zoodles in the oil and sauté very quickly, about 1 or 2 minutes, until just softened. Do not overcook the zoodles or they will become watery and mushy.
  8. Place the zoodles in a large serving dish and toss with the Alfredo sauce. Finish off with some grated parmesan, a sprinkle of black pepper and some fresh basil. Serve immediately, or let the sauce cool down, cover and refrigerate for up to 5 days. Serve with freshly prepared zucchini noodles. Keto Zucchini Noodle Alfredo

I tried this last evening but I added some lobster that needed to be used up, it was so good, but very rich, couldn't eat a lot at a time.  Will definately make this again, although I have lots left over this makes a large amount!

Oh my goodness Martina, this Sauce was outstanding! I could have just eaten it with a spoon...but I made Spaghetti Squash noodles for me and Pasta for my husband (?)....we both thought it was a real keeper! Thank you, again!

I agree, this is the perfect recipe for family cooking! I'm glad you enjoyed! 😊

I made this last night and it was so good! Thank you so much. This is the best tasting Alfredo I’ve ever had and it was so easy. I was curious to know if you have the nutritional values for the sauce alone? I use less than what a serving calls for, so I’d like to be able to log the zucchini and sauce separately, if possible. Thanks!

Hi Juli, it the sauce itself is 4.2 g total carbs, 4.1 g net carbs, 13.7 g protein, 66 g fat, and 657 calories per serving. I hope this helps!

Love, love, love Alfredo sauce!  I too miss pasta and am not a big fan of zucchini as a substitute.  I love using kelp noodles (Sea Tangle Konaberry) as they have ZERO taste and provide a neutral base for any sauce. Out of the package, the noodles are oddly crunchy unless they are cooked in an acidic sauce like tomato-based spaghetti sauce or a lemon-based butter sauce.  
I have found a great way to soften the noodles to feel like an authentic pasta without leaving a lemon flavor.  Just soak them in water acidified with cream of tartar!  They should soften in 20-30 minutes or so.  Just rinse and they are ready to be used as a base for "sweeter" sauces like a cheese sauce.

I love kelp noodles! Thank you for the useful tips. I never thought of this and actually because of the crunchy texture I only used them in salads and soups. Good to know! 😊

This was amazing! Well worth the bit of patience required for cheese melting!

Thanks for the recipe - it looks great, as always.
I love the concept of zucchini noodles and they seem like a great alternative even for people who aren't on a low carb diet. But, I have struggled to find recipes that I would truly enjoy. This one seems like it would be well worth trying.
