If you haven’t used spaghetti squash before, you need to. It is without a doubt my favorite veggie-based pasta replacement! Unlike some other options, this type of squash really absorbs the texture and flavors of its sauce, making it a solid, healthy base for your favorite toppings.

NOT-SO-PRO TIPS
If you want a thicker sauce, “wring out” your cooked spaghetti squash to take out as much water as possible
You’ll know your squash is cooked when you can rake a fork over it and come out with spaghetti like strands. In my experience, though, I have both over and under cooked it by a bit and still come out with a delicious dish!
