Zucchini season is here, zucchini season is here! Can you just imagine me shouting this from a rooftop? That’s what I feel like doing right now because that also means it’s zucchini Alfredo season. And that is is one of the best times of the year, don’t you think? Keto zucchini noodles alfredo is the meal you’ll want to make over and over again. It’s a classic for a reason! And so much easier to make at home than you might think. Once you spiralize your keto zoodles, you’ll whip up your quick Alfredo sauce to drizzle over the top. And I’m sharing even more keto zoodle recipes below, because I know you’ll want to try them all during zucchini season!

My absolute favorite use of zucchini is zucchini noodles, keto zoodle spaghetti, or zoodles – there are so many different names!

Place your zucchini in a spiralizer, give the handle a few cranks around, and voila – you’ve got gorgeous, delicious zucchini noodles. The first time I tried it (years ago), I couldn’t believe how easy it was. You can also use a julienne peeler to create zucchini noodles manually, if that’s what you have.

Either way, if you’re missing pasta, zoodles are your perfect solution. And, my zucchini noodles recipe will make it super easy for you.

The zucchini noodles are the star of these zucchini pasta with Alfredo sauce, keeping the dish light, colorful, and delicious. For as long as I can get my hands on good zucchini, I’ll be making zoodles Alfredo all summer long – and well into fall.

How To Make Zucchini Alfredo

Ready to see how to make zucchini Alfredo? It’s super simple:

Prep the zoodles. I have a whole guide about how to make zucchini noodles here, which goes into many different preparation methods and which ones I think are best. Be sure to check it out if you love zucchini noodles.
Make the Alfredo sauce. In a skillet, you’ll cook together butter, garlic, almond milk, heavy cream, and nutmeg. Then you’ll whisk in the arrowroot powder and Parmesan cheese. The small amount of arrowroot powder is the key to thickening the sauce without flour (though you can also use xanthan gum instead, to further reduce carbs if that is a priority). Alternatively, if you don’t need the Alfredo sauce to be lightened up on calories, you can make a classic keto Alfredo sauce like this. It’s a bit heavier, but low in carbs.
Cook the keto zucchini noodles. In a hot skillet, stir fry until barely softened, but still crunchy.

TIP: Make sure you don’t over cook the zoodles. We want them crunchy, not soggy!

Toss the zoodles with the Alfredo. Zucchini pasta Alfredo is ready to eat!

TIP: Serve the zoodles Alfredo right away. It can get watery if it sits.

What Is The Texture Of Zoodles?

The texture of zoodles can vary greatly. It all depends on how they are prepared. I recommend cooking them lightly and quickly so they don’t get too soggy.

Raw zoodles have a crunch similar to cucumber, but lightly cooked they are a little softer and more tender. If you prefer a noodle with more traditional texture, give these keto egg noodles a try.

Is Alfredo Sauce Healthy?

Alfredo sauce can be healthy! This zucchini noodle Alfredo is made with just 7 simple ingredients – no weird fillers or gums like some of the store-bought versions. One of the reasons I love to make my own food is because I know exactly what goes into my recipes.

How To Store Zucchini Noodles Alfredo

Zucchini noodles are best served fresh! I would recommend making the amount you will eat, or prepping the zoodles and making the sauce ahead of time.

You can spiralize them in advance and keep them in the fridge uncooked. Then, when you’re ready to cook, pat them dry first.

Cooking zoodles ahead of time is also not recommended, but if you must, do not mix them with sauce until ready to serve. They will continue to release water after cooking, so pat them dry again before adding sauce and serving.

Can You Freeze Keto Zoodles?

No! Do not freeze keto zoodles. I repeat, do not freeze keto zoodles. Do not freeze zoodles. Trust me, I’ve tried and my attempts resulted in a watery mess and weird texture.

What To Serve With Keto Zucchini Noodles Alfredo

This zucchini noodles Alfredo doesn’t need much, but I do like to add a protein to it so that it’s a filling meal. It can be as simple as:

Juicy baked chicken breast or blackened chicken cut into slices
Air Fryer Shrimp
Tuscan garlic chicken
Crispy chicken thighs
Sirloin steak
Seared scallops

3 medium Zucchini ▢

2 cloves Garlic (minced) ▢
1/4 tsp Nutmeg (or 1/2 tsp if you like a stronger nutmeg flavor) ▢

Make zucchini noodles using a spiralizer or julienne peeler.
Melt the butter in another skillet over medium heat. Add garlic and cook about one minute, until soft and fragrant.
Reduce heat to medium-low. Stir in the almond milk, heavy cream, and nutmeg. Bring to a gentle simmer.
In a small bowl, whisk the arrowroot powder with just enough water to dissolve it (1-2 tablespoons (15-30 mL)), until smooth with no lumps. Whisk the mixture into the sauce on the stove. Whisk in the parmesan cheese. Add black pepper to taste. Continue to heat, stirring constantly, until the cheese is melted and the sauce starts to thicken. Remove the sauce from the pan, cover, and set aside.
Pat the zucchini noodles dry with paper towels. Add the zucchini noodles to the pan and turn up the heat to medium-high. Stir fry until barely softened but still crunchy, about 2-4 minutes. Stir in the sauce. Garnish with fresh parsley and additional parmesan cheese if desired.

Hi. Made this twice, and both were delicious. The second time I added sautéed mushrooms. Thank you for the great recipe.

I appreciate the recipe; this was my first time making zoodles. My little hand powered zoodle-maker took longer than expected, but I got it done.

hello, sorry if this has already been asked, but if using pre cut zucchini noodles, how many cups of zucchini would you use?
thanks Hannah

Is it possible to make it without nutmeg? I wasn’t really a fan of that taste.

  Hi Monica, Yes. You can skip the nutmeg, that’s fine.

SO good. I think I like this better than regular fettuccine Alfredo!! I added sautéed garlic/butter shrimp on top for some protein! Thank you!

I’ve made your 25 minute zoodles Alfredo 4 times now since finding it a couple of months ago. I love the flavor of the sauce, the nutmeg really enhances any Alfredo sauce I’ve ever made before. I don’t combine my sauce and zoodles like you do, because we all like different amounts of sauce, and I’ve found that separately they each reheat better later than if it were combined

Can you use a cornstarch slurry instead of arrowroot?

  Hi Robin, that would work but you might increase the net carb count.

Very good. I enjoyed the recipe. I added 5 red jalapenos from the garden ( don’t have much spice) and some turkey. Oh and a little cooked bacon! I cooked the zoodles right in the sauce without a problem. The sauce was thick to start with and the water from the zoodles thinned it out a little. It takes alot of zoodles to fill us up. FYI I am enjoying your recipes!

Here’s an updated tip for zucchini noodles…the air fryer! If you have on just 4 minutes in the air fryer gives lovely warm zucchini noodles that aren’t soggy! Yay!

Is there any way to substitute the cream? I can’t have dairy but this recipe sounds amazing.
- Maya | Wholesome Yum

  Hi Michele, You could use coconut cream instead.

If I use regular milk instead of almond milk would I use the same amount?
- Maya | Wholesome Yum

  Hi Michelle, Yes, it’s the same amount.

Would it be ok to use coconut flour instead of arrowroot?
- Maya | Wholesome Yum
  0 February 27, 2018Reply
  
  Hi Stephanie, The arrowroot is there as a thickener, so coconut flour wouldn’t really achieve the same thing. You could use something like xanthan gum to thicken instead, OR use less milk and more cream which will naturally thicken. Hope that helps!

Do you have to use almond milk? I don’t like the taste when used in savory dishes. Thanks.
- Maya | Wholesome Yum
  0 December 22, 2017Reply
  
  Hi Lina, coconut milk would also work for this recipe. You could also replace the almond milk with more heavy whipping cream which would make the sauce thicker and more rich.

How many carbs will it have if I substitute with xanthan gum?
- Maya | Wholesome Yum
  0 November 28, 2017Reply
  
  Hi Sarah, I don’t have the calculation off-hand but it wouldn’t be a huge difference since the arrowroot powder is spread out across multiple servings and there isn’t a lot of it. If you need exact nutrition info when making substitutions, you’d need to enter the ingredients you’re using into an online calculator.

Is it possible to lose weight with this much fat in recipes?
- Maya | Wholesome Yum
  0 October 7, 2017Reply
  
  Hi Holly, Yes, absolutely – as long as you are not eating many carbs. High carbs AND high fat definitely won’t result in weight loss. Carbs actually lead to weight gain much more than fat does.

Do you use two pans cook zucchini noodles separately ? It says to add to sauce or did I read it wrong?
- Maya | Wholesome Yum
  0 February 11, 2017Reply
  
  Hi Cathy, You don’t need two pans, just one pan. You make the sauce in the pan first (steps 1-4), then at the end of step 4 remove the sauce from the pan (transfer to a bowl) and set aside. In step 5, you can cook the zucchini noodles in the same pan. You don’t have to clean it beforehand, just remove the sauce, but if your pan sticks easily you may need to add a little oil to it. Cook the zucchini noodles as directed, then stir the sauce back into the pan. Hope that clarifies it a bit!

I think the protein content is wrong (20 grams is for the whole dish).
- Maya
  0 June 24, 2016Reply
  
  Hi Christina, Thank you for catching that! 20 grams was actually not for the whole dish, but it was higher than the actual amount. The nutrition calculator had the incorrect amount of Parmesan cheese set, so both fat and protein were listed in the nutrition label as higher than they actually are. I updated (and double checked) the nutrition info, so it should be correct now. One serving has 11 grams of protein, which is still great!
