This creamy paleo chicken Alfredo is packed with flavor, quick to throw together and great for weeknights! Tossed with perfectly “al dente” spaghetti squash, this meal is gluten free, dairy-free, low carb and Whole30 compliant.
Is there anything better than a creamy “cheesy” (but no cheese!) sauce?! I’ve come to love making cheesy dairy free sauces with cashews.
Trust me – it took awhile for me to warm up to the idea of cashews creating deliciously creamy sauces – but hey – it works!
Whether it’s for my chicken burrito casserole, roasted garlic chicken pizza, or bacon cheeseburger casserole, there’s really no better way to create a paleo and Whole30 friendly sauce that tastes shockingly like it’s loaded with dairy.
Enter today’s Paleo spaghetti squash chicken Alfredo! It’s simple and quick with just the touch of a button on your blender. The chicken is juicy and flavorful and the spaghetti squash is cooked just right (not mushy!)
What You Need to Make Paleo Chicken Alfredo
The Alfredo sauce is cashew based sauce that’s super creamy and perfect tossed with spaghetti squash. I used unflavored, unsweetened almond milk for this recipe because I thought coconut milk would overpower the flavor a bit. You can use whichever one you prefer or have on hand. Here’s what you’ll need for the recipe:
- Raw cashews
- almond milk or coconut milk, unsweetened
- garlic
- lemon juice
- nutritional yeast
- 1 med/large spaghetti squash
- Avocado oil or avocado oil spray
- Sea salt and black pepper
- Boneless skinless chicken thighs or breasts
- dried oregano
- dried basil
- Fresh Basil or parsley for garnish
How to Make Paleo and Whole30 Chicken Alfredo
Make the Cashew Alfredo Sauce first. In a high-speed blender (I used a VItamix), combine all ingredients. Blend until completely smooth. Sauce should be warm by the end of blending, if not, transfer it to a saucepan to heat before serving.
For the Spaghetti Squash and Chicken, roast your squash first. See tips below (and the recipe box!) for the best way to do this.
Meanwhile, season the chicken thighs generously on both sides with salt and pepper, then sprinkle the oregano and basil all over. Heat oil or ghee over medium-high heat and add chicken to the skillet. Cook 5-6 minutes on each side, lowering the heat to medium to avoid burning the outside, if necessary.
Once the chicken is cooked through, remove from pan to a cutting board and let it sit a few minutes. Slice it into strips or bite size pieces using a sharp knife.
Use a fork to scrape the “spaghetti” strands from the squash and place in a serving bowl. Top with the Alfredo sauce and chicken, then garnish with basil and/or parsley as desired.
How to Roast Spaghetti Squash for Paleo Chicken Alfredo
I prefer my squash “al dente” which means that overcooking it is just about the worst thing ever! Therefore, I like to undercook it just a touch since it tends to continue to soften after coming out of the oven.
Preheat your oven to 400°F and line a baking sheet with parchment paper. Cut the squash in half lengthwise (it roasts faster!) and scoop out the seeds and strings. Spray the inside of the squash with avocado oil spray or brush with oil, and sprinkle with sea salt and black pepper.
Place squash face down on the baking sheet and roast in the preheated oven for 22-25 minutes, depending on size and preference for softness. You can press down gently on the back of the squash to see if it’s tender. Once it’s just a little bit tender, remove it from the oven and wait until it’s cool enough to handle before proceeding.
I hope you’re ready for a delicious way to enjoy spaghetti squash – with the most delicious creamy Alfredo sauce that just happens not to contain any dairy. You’ll love it, I’m sure – grab everything you need and let’s go!

What can I use instead of spaghetti squash? We don’t have that here. Thanks!
could try zucchini noodles (just spiralize zucchini) my bf didnt like spaghetti squash so I’m going to try it with zoodles next
I made this tonight and it was delicious!!I had planned on making the Instant Pot chili, but had an evening that was surprisingly quiet for kids’ activities and had some extra time for dinner. I am still getting the hang of cooking spaghetti squash (I always second guess myself and end up overcooking), but it was still good.
I made this sauce tonight, for my husband and myself. I put it on gluten-free pasta and sliced chicken breast. He loved it, as did I. It is important to me that my husband likes what I serve and he thought this was better than the dairy choice. It’s a win. Thank you so much!
What can I use instead of spaghetti squash? We don’t have that here. Thanks!
This recipe was absolutely amazing! It was so easy to make and the flavor was delicious. I did dice the chicken ahead of time and cooked it like that and added some broccoli while cooking the chicken to add some greens. This is a new family favorite, thank you for sharing.
This was delicious. I had to change up a little as I did not have nutritional yeast and am allergic to chicken. So had turkey thigh meat one time and the next time I used ground turkey cooked with onions and garlic. This sauce is good on veggies as well. Can’t wait to try with yeast when I can get it.
Is there anything I can substitute Cashews with? I unfortunately have an allergy 🙁
This dish was amazing! It tastes just like normal Alfredo, whole family loved it!
I’ve never had the nerve to try spaghetti squash… Maybe it’s because I love pasta so much?
Can you freeze the sauce and save it?
Oh my goodness, this was so good! It is now, forever, my go to non dairy, healthy sauce! So eager to try it with other things. Thanks! PRM!
Are almond milk and coconut milk the only milks recommended due to the consistency of the sauce they would create? I have original, unsweetened Ripple milk on hand. Do you think that would create the desired consistency of sauce as well?
This is a great meal that takes very little time to prepare. The food is very delicious and rich in nutrients.
We had this for dinner, it’s so good!
This was really good! I was nervous about the cashews actually making a sauce but OMG it was delicious! My whole family enjoyed it including my 6 year old. Thank you for a delicious recipe
So delicious and the whole family loved it! The kids even had seconds too!!
I did make this which was super good!! Only thing is I thought the sauce was too thick. Is that from the nutritional yeast? Also are you able to use coconut milk instead of almond milk?
same, way too thick. was disappointed
Loved this recipe
I cannot get enough of this dish. I have made it for regular noodles and spaghetti squash it is perfect with both. I always add a little more garlic to every recipe, but other than that, its perfect. I have made it 3 more times since first discovering it. I honestly think I might like it more than regular alfredo sauce!
This was so good!! Needed some great comfort food tonight and this hit the spot. Saving this recipe!
I want to try this but I am concerned my Ninja won’t make the cashews smooth. Any tips? I recall having issues making a soup with cashews, but I think that was using an immersion blender.
Any substitute recs for cashews? We have a tree nut allergy in our house.
Fantastic recipe! Tastes like authentic alfredo.
This does not taste like any decent Alfredo sauce available. I used store bought almond milk and the “Alfredo” is MUCH thicker than shown in the photo and had to be diluted further. The raw garlic is way too potent and the sauce just tastes like a tangy lemon and garlic sauce. I don’t understand how this recipe could receive such high reviews.
Really good taste and easy to make. My 5 year old helped. I used roasted chicken from the store as a shortcut.
Great sauce. Used it for sweet potato and lentil noodles instead of spaghetti squash and it was super smooth and delicious. Thank you
Also, forgot to add that I toasted the garlic on high heat on a frying pan before adding in to the blender. 👌🏼
Can I substitute almonds for the cashews as we have a cashew allergy?
So delicious! Her recipes never disappointment. I only made the Alfredo sauce and used GF pasta with grilled salmon. My dairy-gluten eating husband even loved the sauce!
New favorite alfredo recipe!! So good and easy!!
Loved this recipe so delicious 🤤
Only problem was my ninja didn’t get the sauce as smooth as it shows in the picture but I still enjoyed the flavor.
This was not your typical Alfredo. Granted I had to use cashew butter which made it much thicker than it may have been, but nothing a little water couldnt fix. I have to say ive never eaten anything so delicious with spaghetti squash. I threw blackened chicken on top and dairy free parm and I am blown away. This kinda reminded me of a Thai style in a way, you can def taste the nuttiness of this! So good thank you!
Oh my, this is delicious! I didn’t have almond milk (my almonds were old), so i subbed with coconut milk. Im looking forward to making it again with the almond milk.
Can’t wait to try this.
Very good! Have you tried doubling the sauce and freezing some?
This was so good! Will definitely be making this again. I used Rotisserie Chicken instead which made the dish a little faster to put together. Thank you for sharing so many fabulous recipes 😊
Hi, the recipe looks delicious! I’m fasting at the mo and drooling over the image. I’ve never cooked spaghetti squash b4. I’m intimidated. Lol. Do you have a YT channel?
You’re making my stomach rumbling with that recipe:)) Im sure you’ll be the next masterchef
It was very good.
Can you make the sauce ahead of time? If so, how long can I store it in the fridge in a mason jar?
This was very tasty, and I hope to make it again…and figure out how to thin out the sauce. Perhaps soaking the cashews, lessening the amount of cashews, or adding in more almond milk would work?
Can I still soak the cashews? I don’t have the best blender. I’m worried about breaking it.
Looks amazing
This was an excellent recipe. My husband and I enjoyed it.
This recipe looks absolutely delicious! Can’t wait to try it.
This turned out great, but need a recommendation on how to balance the sweetness of it.
Not a fan of cashew cheese sauce. Way too thick and has a weird sweet taste. I tried to like it but it’s a no for me!
This is so amazing! I was so sad when I had to go paleo because I love a good cream sauce…this you would never know it isn’t dairy. I just love all your recipes. Your favorite chocolate cookies make a delicious dessert to go with this;)
