When you see a recipe that has cheesy and vegan in the name, you know what’s coming, right? Nutritional yeast, of course! An ingredient near and dear to me and big time staple in any healthy, vegan kitchen. However, you certainly don’t have to be vegan to enjoy nutritional yeast! It adds a delicous, cheesy flavour to this spaghetti squash marinara, is fortified with vitamin B12, it’s high in plant-based protein and is a versatile ingredient to stock in your panty.

Amazing Spaghetti Squash

Spaghetti squash: low in fat and carbs, low calorie, packed with vitamins and minerals, great for food prep, delicious, versatile…what’s not to love? And now about it how it morphs from a solid squash into amazing spaghetti squash noodles? Crazy, right? I really love spaghetti squash in fact, I love it so much I make one every single week as part of my weekly food prep.

My favourite way to cook spaghetti squash is to roast it face up at a high temperature. Head over to my post on How to Cook Spaghetti Squash for a step by step on cooking spaghetti squash for best results.

Easy Cheesy Vegan Marinara Sauce

You can’t go wrong with this super easy and cheesy vegan marinara sauce. To keep things simple for fast weeknight meals, I use a jar of store-bought marinara sauce to make it and simply adding fresh onions, garlic and nutritional yeast. I like mine spicy so I always add a generous teaspoon of red pepper flakes too.

If you’re in a pinch, you can skip the onions and garlic, add a jar of marinara sauce to your spaghetti squash and top with nutritional yeast but I like the extra flavour and texture from sauteéd onions and garlic.

I love this sauce with zucchini noodles too or even regular pasta on the rare occasion that I eat it. A full half cup of nutritional yeast take the flavour next level and the sauteéd onions and garlic add that classic marinara flavour.

Spaghetti Squash Marinara

There really isn’t much to this recipe: one delicious, roasted spaghetti squash and a pan of easy cheesy vegan marinara sauce! That’s it.

If you cook the spaghetti squash ahead of time it can be ready in just a few minutes. It’s low calorie, so you can enjoy a big satisfying serving that will fill you up. If you want to add more plant-based protein to this dish, try topping it with crumbled tempeh, stirring in some tofu, lentils or chickpeas or adding some seitan.
