Heat olive oil in a frying pan over medium-high heat, add onions and mushrooms. -
Lower the temperature to medium and cook onions and mushrooms until beginning to brown, about 10 minutes, stirring occasionally to prevent burning.
-
Add broth, wine, or water to the pan. Using a flat–edged wooden spoon “scrape” the bottom of the pan to pick up the brown bits.
-
Cook onions and mushrooms for 8-10 minutes more, until there is no more liquid in the pan.

4. Remove squash from the oven, scoop out flesh, and then place in the prepared casserole dish.
5. Stir in caramelized onions, mushrooms, tomato sauce, garlic powder, whisked eggs. Season with ½ teaspoon salt and ½ teaspoon pepper. Mix everything together until you can no longer see eggs.
6. Bake uncovered at 400°F for 1 hour, until the top of the casserole has formed a golden crust that is brown around the edges. Let rest for 10 minutes before serving.
