Vegan Alfredo Spaghetti Squash with Broccoli

Plant based deliciousness has arrived to my kitchen and I couldn't be more excited about it!  This vegan alfredo spaghetti squash is the answer to my comfort food prayers, and for someone who has been eating dairy and cheese her whole life, I never would have guessed this was vegan.


My Plant-Based Journey

My plant-based journey started about a month ago when my husband and I were living in Costa Rica.  I was basically forced into a mostly plant-based diet, eating tons of fresh fruits, vegetables, beans and rice that I made on the stove top and of course so much fresh fish caught from the beach.

For as long as I can remember I have always had so much bloat and the number on the scale wouldn't budge.  I'm very in shape but the water weight was simply weighing me down.  As I started into this plant-based lifestyle while we were down there, I gradually started to feel lighter, my tummy got flatter and my energy skyrocketed.  I knew from then on that this was the food I was meant to eat.  

As annoying as it may be, I thought if it's working, why fight it?  When I got home I realized I had dropped 5 pounds, and that sealed the deal.  

Not only do I feel really good, I also am really happy to know that I'm giving myself nutrients and foods that are nourishing me rather than hurting me.  

So of course this meant a whole lot of research into cooking plant-based, and finding new alternatives to the foods I've always alfredo sauce.  Especially in the colder months, I love making spaghetti squash boats filled with an alfredo sauce I made with greek yogurt and whipped cream cheese, tossed with broccoli, chicken and sun dried tomatoes.  That is now a recipe of the past for me, so I had to come up with an alternative!

Cashews & Nutritional Yeast

Cashews are what makes vegan "cream-based" sauces so creamy...without the cream, and nutritional yeast is what gives it that cheesy flavor we all love.  I was very skeptical of nutritional yeast at first, and I have seen it and heard about it for years, but when push came to shove and I finally tried it, I actually really LOVE it.

The key to using cashews in a sauce is to soak them either in water for up to 12 hours or for just 5 minutes in a bowl of boiling water.  By soaking them you'll get a softer cashew making for a much smoother sauce.

I also used half an onion and lots of garlic, sauteed in olive oil and a little salt, to give it more of that Italian-alfredo taste.   

The lemon juice in the sauce gives it a little extra zip and flavor, and then you'll want to add more salt to taste if needed.  

Protein on a Plant-Based Diet

People get so hung up on protein!  On a plant-based diet, you're getting ample protein and essential nutrients from beans and other legumes, nuts, seeds, grains, vegetables and even fruit!

For this dish, your protein is coming from the cashew-based sauce and the non-dairy almond cheese, and you'll feel full and satisfied from the fiber-rich spaghetti squash and broccoli.  There's a whole lot of debate about protein in vegan, vegetarian and plant-based diets that I won't get into with this post, but I promise you you'll be full and satisfied with this comforting meal.

Vegan Alfredo Spaghetti Squash with Broccoli

You can switch this up any way you'd like - add chicken if you're just looking for a dairy-free option, or keep the original recipe but add baby spinach for an extra boost of iron, calcium and minerals or mushrooms for more heartiness.  This can be a very versatile recipe.

My husband Ryan has 100% approved this recipe, reminding me constantly as I write this post how incredible it is -'s husband approved!

I noticed you said to drain the cashews from the water. Just wanted to clarify that we are not blending the cashews, but instead using the cashew water? Thank you!!

    Hey Tanya!

    Thanks so much for trying my recipe!! You are blending the cashews – you can discard the water they soaked in. The hot water helps to soften the cashews to give the sauce a creamier consistency 🙂 LMK how the recipe turns out for you!
