Shred the cooked squash using a fork to create strands. This texture gives your gratin that signature noodle-like quality.
-
Sauté the diced onion in a saucepan over medium heat until softened. Then, add minced garlic and cook for an additional minute until fragrant.

Spaghetti Squash Au Gratin Recipe FAQs
How do I choose the right spaghetti squash?
When selecting spaghetti squash, look for firm, heavy squash with a smooth, unblemished skin. Avoid those with dark spots or soft areas, as they may be overripe. A good squash should feel solid and not have any notable discolorations.
