In January, John and I decided to do a two-week overhaul on our diets. Since the aftermath of holiday gluttony left us both craving naughty stuff on a daily basis, we knew something had to be done. So Goop’s annual detox diet came to the rescue with a one week meal plan that eliminates gluten, dairy, sugar, soy, caffeine and alcohol.

The first few days were ROUGH, I’m not gonna lie. But the recipes were vibrant, imaginative and so nutritious that we started to feel great after the initial battle with the cravings wore off. Holiday bloat? Gone. Energy levels? Way up. Jeans? Fitting perfectly, thank you very much.

In fact, we felt so incredible that we decided to shift towards a primarily plant-based style of eating, while limiting things like gluten and refined sugar and incorporating smarter protein choices like organic pasture raised eggs and wild caught seafood on occasion.

Which brings me to this vegan, gluten free, low carb, SO INCREDIBLY SATISFYING Spaghetti Squash Alfredo.

Best of all this vegan Alfredo sauce is packed to the brim with good for you ingredients such as:

  • cauliflower
  • almond milk
  • lemon
  • garlic
  • nutritional yeast
  • nutmeg
  • vegan butter- my favorite is Miyoko’s cultured coconut butter made from pure ingredients!
  • salt

Serve it on top of roasted spaghetti squash (another one of nature’s treasures) that’s been roasted to perfection and your creamy vegan pasta cravings are hereby met.

How to cook spaghetti squash

Spaghetti squash is another one one of those healthier ingredients that totally satisfies a carb craving. I like to halve it and roast it in the oven, and since a raw spaghetti squash can be hard to cut into, I’ll toss the whole squash into the oven as it’s pre-heating for about 10 minutes to par bake it and soften it a bit. When you take it out of the oven and let it cool enough to handle, it will be so much easier to cut in half, and the seeds are easier to scoop out too!

Next I’ll drizzle a bit of olive oil on each half and finish roasting it in a baking dish in a 400 degree oven until the strands are soft and pliable.

One the spaghetti squash is cool enough to handle, I remove the strands with a fork and place them in a bowl. I definitely recommend seasoning the spaghetti squash by tossing it with some olive oil, salt and garlic powder, separating the strands as you go.

Tips and variations for making this Spaghetti Squash Alfredo recipe:

  • Toss some of the sauce with the spaghetti squash and serve some on top as well for maximum creamy goodness.
  • Serve this vegan Alfredo sauce with zucchini noodles or butternut squash noodles instead of spaghetti squash.
  • If you want to top this dish with a protein to it more substantial, grilled chicken/veggie chicken strips, shrimp or meatballs/veggie meatballs would all be very tasty!
  • Other toppings ideas to jazz up this dish include fresh herbs, chopped cherry tomatoes, toasted breadcrumbs and crushed red pepper.

    I’m a HUGE sucker for spaghetti squash. I think that veg makes more appearances on my blog than any other. And I find myself cooking with is most during Jan/Feb, when I’m trying to detox as well. For some reason I always find myself eating cookies for breakfast in December… oops. This recipe looks great!!

      Thanks Chris! I think we all need a little reset after the holidays, spaghetti squash to the rescue to trick our tummies into thinking we’re still eating something indulgent!
