How to Perfect Creamy Spinach and Mushroom Stuffed Spaghetti Squash

- Sauté veggies properly: Cook onions and mushrooms until browned to enhance their flavors before mixing them into the filling.
- Balance flavors: Adjust salt, pepper, and nutmeg based on your taste preferences for a well-seasoned dish.
- Experiment with cheeses: Try using different types of cheese like goat cheese or vegan alternatives for unique flavor variations.
- Serve immediately: For the best experience, serve the stuffed squash right after baking to enjoy the melty cheese and fresh ingredients.
