Yes! You can also prep it ahead this way. To do so, you can cook the spaghetti squash the night before (or a few hours prior to serving). Once it's completely cool, scrape the squash out of its peel and place in an airtight container. Make the dressing up to three days ahead. Store in the fridge until ready to assemble. Bring the dressing to room temperature before pouring over the spaghetti squash.
