Preheat the oven to 375 degrees F and line a baking sheet with parchment paper. Carefully slice the spaghetti squash in half length-wise and remove the seeds. Place on baking sheet, cut side down. Bake for about 35-40 minutes until a fork can easily pierce the skin.
While squash is cooking, add bacon to a large skillet set over medium heat. Cook for 2-3 minutes until crispy. Reduce heat and add garlic.
Whisk in heavy cream, parmesan cheese, egg and egg whites in a small bowl.
When squash is done baking, remove from oven and pull “noodles” out and add to your pan. Stir in cream mixture. Remove from heat and garnish with freshly parsley and extra parmesan cheese if desired.
