Preheat the oven to 425 degrees F (220 degrees C). Line two baking sheets with parchment paper.
In a mixing bowl, combine the ground beef, onion, garlic, basil, thyme, and salt. Form the mixture into meatballs and transfer to one of the baking sheets.
On a separate baking sheet, place the spaghetti squash flesh-side down. Cook the squash for about 30 to 35 minutes (or until fork tender), and the meatballs for 15 to 20 minutes (or until cooked through).
Meanwhile, warm up the tomato sauce in a saucepan over low-medium heat.
When cool enough to handle, use a fork to shred the squash into noodles. Top with the meatballs and tomato sauce.
