This vegetarian favorite is packed with nutrients and flavor without sacrificing indulgence. The squash provides fiber and vitamins, while the double bake creates a crispy, golden top that contrasts beautifully with the tender, spaghetti-like strands.

The second bake enhances texture and flavor, creating a deeply satisfying, restaurant-quality result. This dish isn’t just a casserole—it’s a celebration of seasonal ingredients and thoughtful baking.
