A rich and creamy chicken alfredo that’s super healthy! Quick and easy to throw together, this healthy chicken alfredo uses a dairy-free cashew alfredo sauce and spaghetti squash “noodles.” Paleo and Whole30.
Can we talk about my low, low expectations for this recipe?
Really, though. I was making it like, “Haha, this is fun. This a fun waste of time. I mean, there is no way this is going to be really damn good. And ‘really damn good’ is the requirement for an appearance on my blog, didn’t you know that? So this is a fun waste of time.”
And then I had a bite and punched the person next to me, just out of sheer knee-jerk reaction, because I had not been eating this my whole life and I felt deeply deprived.
Why this healthy chicken alfredo is so good
It’s chicken alfredo. But healthy. And creamy and rich and delicious. And quick and easy. And it’s paleo and Whole30-compliant! I mean, truly, it’s just my everything right now.
- This healthy chicken alfredo is shockingly rich and creamy and satisfying.
- The dairy-free alfredo sauce tastes way too close to real, cheesy alfredo sauce, but with none of the dairy! That makes it perfect for those with dairy sensitivities or lactose intolerance, those on a paleo or Whole30 diet, and breastfeeding moms who’s little ones are sensitive to cow’s milk proteins.
- The spaghetti squash keeps this healthy chicken alfredo focused on whole foods and totally gluten-free.
- It’s super quick and easy to whip up! The alfredo sauce is made in the blender, and the chicken is cooked in under 10 minutes on the stove.
How to make healthy chicken alfredo
It’s a little too easy. Ready?
Heat avocado oil in a large skillet over medium-high heat and season both sides of chicken liberally with salt and freshly cracked black pepper. Add chicken breasts to skillet and cook 8-9 minutes total for medium chicken breasts and 9-10 minutes total for large chicken breasts, flipping once midway. Once they’re cooked through, transfer the chicken breasts to a cutting board or plate and let rest 5 minutes.
Meanwhile, make your healthy and dairy-free alfredo sauce!
Combine all the alfredo ingredients in a high-speed blender and process until totally smooth. If your blender heats its contents, great! Just process until it’s hot, and you’re set. If your blender does not heat up its contents, transfer the alfredo sauce to a saucepan after it’s completely smooth and heat through over medium-low heat.
After chicken has rested 5 minutes, slice against the grain.
Heat your prepared spaghetti squash through then top with alfredo sauce and sliced chicken. Garnish with chopped fresh parsley and more freshly cracked black pepper.
How do you cook spaghetti squash?
Cooking spaghetti squash is similar to cooking all other winter squash: you start by halving it and scooping out the seeds. Then, roast the halves at 400º F for about 30-45 minutes or until a fork easily pierces the flesh. If the squash is still a bit firm, keep roasting for another 10 minutes or so, or until it’s quite tender.
You can add a bit off water to the baking sheet or roasting pan when cooking to help the spaghetti squash steam; try adding about 1/2 cup to the pan before putting it in the oven.
After the spaghetti squash is tender, remove from the oven and let cool slightly. Use a fork to scrape out the spaghetti squash strands, gently separating them.

Add a little water if you like, about 1/2 cup, to help steam the squash. Roast at 400º F for 30-45 minutes or until easily pierced with a fork. Remove from oven and let cool slightly, then use a fork to gently scrape the flesh out of the skins, separating the flesh into strands or "spaghetti."

I was a bit skeptical while I was making this but every recipe that I’ve tried from you has been a hit so I pushed on. It turned out a bit thick but that is probably because I used original nut pods creamer because that was all I had on hand. I also took a suggestion from one of the comments to roast the garlic first which turned out amazing. I will definitely be working this into our weekly recipes! My husband even liked the sauce and he doesn’t like much 🙂
Made this as suggested. It was very good but texture was a little granular and garlic extremely strong. Made it a second time, soaked the cashews first and roasted the garlic. Perfection. I will use this instead of traditional Alfredo even when I am off the whole30.
My picky eater siblings DEVOURED this. We’re on Whole30 right now and I added a bit of cayenne pepper and used a mix of unsweetened almond and coconut milk and then sprinkled parsley and vegan parmesan on top. 😋 they all agreed they couldn’t even tell the difference between this and “regular” alfredo sauce. Will definitely be making this more regularly! Thank you so much!
Do I need to soak the cashews before ?
No need to soak if using a high speed blender. 🙂
I make this probably every week on whole30! it is SOOO darn good! thank you!
I am not a fan of almond milk. Is there much different in taste from using the water versus almond milk? Or is there another Milk substitute I can use?
Feel free to substitute unsweetened cashew, macadamian, or coconut milks for the almond milk.
Making this tonight and I only have vanilla almond milk. Would it be better with vanilla almond milk or water? Thanks! Can’t wait to try it!
Hi Carrie,
If you use the vanilla almond milk, the flavor will definitely be a bit altered. If the recipe comes out with a sweeter flavor, we would just say to add more salt.
Hi, just wondering if I could skip the yeast? What does it bring to the recipe? Sounds amazing and I will definitely be trying this very soon x
You can skip it! Just adds a bit more nutritional value to the recipe.
My sauce was very thick.. any suggestions?
Was more like a paste than a sauce..
What all did you use?
If I were to freeze this in a small casserole dish all mixed up, do you think it would bake up well. Just trying to put together some healthy freezer meals before our baby comes.
We personally have not tried it, but we encourage you to try it! Please let us know how it works for you.
What is the serving size for this?
The recipe yields 4 servings!
I made my husband a vegan alfredo sauce a few months ago, and he could tell that it wasn’t “the same” as what he’s used to. So this one I will happy try!! The dude loves pasta.
I hope it was successful!
I made this today but found the sauce very thick and hard to heat in sauce pan without burning?? What am I doing wrong?
What can I use for a cashew allergy? Thank you so much!
Try subbing steamed cauliflower!
OH. MY. Goodness!!!!! I have pretty much fallen in love with every recipe I have tried and this did not disappoint! I have recently found your website, as I have recently started eating whole 30, and you have quickly become a fave… Well pretty much my favorite! Thank you for all that you do – keep it coming!
With a full tummy and a happy heart,
Teryn 🙂
My husband is Italian and is super picky about pasta dishes. He was very skeptical about a cheeseless Alfredo. I couldn’t believe it when he went back for seconds! Do yourself a favor and make this dish.
