Eating clean is all about substituting healthy ingredients for unhealthy ones. Some of my favorite subs are replacing sugar with dates, white flour with sprouted grains, pizza crust with gluten-free tortillas, cream with coconut milk, and pasta with veggies.

In my zucchini lasagna recipe, I use sliced zucchini in place of lasagna noodles, and in my zucchini pad thai, I use spiralized zucchini noddles in place of glass noddles. But aside from zucchini, spaghetti squash is another great pasta substitute!

For this roasted spaghetti squash recipe, I’m replacing spaghetti with spaghetti squash. With the added sauce, spices and cheese, I don’t think spaghetti squash tastes all that different from regular spaghetti, but in all honestly, no clean ingredient substitute ever tastes exactly like the original. (The difference is that, once you start consistently eating clean, your taste buds will change, and after a while, the unhealthy ingredients will start to lose their appeal. Sugary foods I used to love are now far too sweet for me.)

The upside to spaghetti squash is that it’s over four times less calories and carbs that regular pasta! While spaghetti squash is around 40 calories and 10 grams of carbs per cup, spaghetti is over 200 calories and over 40 grams of carbs… big difference!

The hardest part about roasting a spaghetti squash is trying to cut the darn thing open! I microwave it for a few minutes to soften it, but you’re still going to need a super sharp knife to split it in half.

The fun part – once the squash is roasted – is scraping out the noodles! (Trust me – it’s fun!) You can also feel free to top it with a few meatless meatballs (Trader Joe’s has bags in the frozen section. They’re made primarily from soy and delish!)
