Preheat oven at 400 degrees F. Line a large baking sheet pan with parchment paper.
Slice spaghetti squash in half lengthwise. Use a spoon or ice cream scooper to scoop out the extra flesh and seeds from the inside of your squash.
Drizzle and rub avocado oil throughout the inside of each half of the squash. Sprinkle Italian seasoning, salt and pepper throughout both halves of the squash. Rub the spices to get them spread all throughout each side of the squash.
Place each half of squash on prepped baking sheet pan facing down with the skin up. Place in the oven and bake for 25-35 minutes until squash is soft and tender.
Remove baked squash from the oven and let it sit for a good 10-15 minutes so it can cool-off enough to handle.
Take first half of the squash and place on a flat surface. Grab squash from the top to get a grip. Using your dominant hand, use a fork and start scraping the inside of the squash. Spaghetti like strings will come out of the squash. Keep scraping until you hit the skin and noodles are completely removed. Repeat the same with the other half of the squash. Place noodles in a large mixing bowl and gently toss all the noodles together.
Serve noodles as is topped with marinara sauce, meat sauce or use in a recipe as needed.
