Spaghetti Squash Alfredo (Paleo, AIP, Dairy-free)

spaghetti squash alfredo via Food by Mars (paleo, AIP, dairy-free)

I’m combining my love of my nut-free dairy-free alfredo sauce with one of my favorite winter veggies ever, the spaghetti squash of course! This recipe is so flexible, I added some ham and broccoli into it, but you can add chicken or bacon and any veggies you fancy, making your own delish spaghetti squash alfredo. The outcome is super creamy and rich, it will warm you right up and become one of your favorite spaghetti squash recipes yet!

This also makes a great packed lunch, easy to re-heat and switch up with toppings/mix-ins to make it different each time. So don’t skimp out on using this for meal prep. If you haven’t had spaghetti squash before, it quite literally looks like spaghetti when you fork out the cooked squash pieces and holds any sauce really nicely. My paleo alfredo sauce is pretty famous in my spaghetti squash pastitsio (Greek Lasagna) recipe and is a staple over here – you will love it!

There are so many great dairy-free and vegan alfredo sauce recipes out there, but they usually include cashews (I even have one here) which is delish and fatty! But to make a nut-free version is a little different. The mix of cauliflower and coconut cream fits the bill perfectly.

    Thank you for this recipe; it is delicious! We love bold flavors so added two cloves of garlic to the blend and a bit more salt. It’ll definitely be a go-to dish for sure. ReplyCancel
