Preheat oven to 400 degrees

Wash spaghetti squash

Line one or two baking sheets with parchment paper. One for each squash

Spread a little of the olive oil over the parchment paper

Slice ends off of spaghetti squash

Slice the squash into one inch rings

Use thumbs to push out the seeded and flesh from the center of each ring

Place rings in single layer on baking sheets

Drizzle with a little oil

Sprinkle rings with sea salt

Bake rings for 30 minutes or until squash is tender

Allow to cool for about 10 minutes

Pull squash from rings. It should come off easily. If it doesn't the squash isn't quite done and needs to cook longer.
