1. Preheat the oven to 475 degrees F.

3. Coat a baking sheet with nonstick cooking spray and evenly spread the onions on the pan.

5. Remove from the oven and set aside.
6. Turn the oven down to 400F (200C).
7. As the onions are cooking, prepare the beans.
8. Bring a gallon of water and 2 tablespoons of salt to a boil in an 8-quart saucepan.

13. Store the green beans in the refrigerator until ready to assemble.
14. Melt the butter in a 12-inch cast iron skillet set over medium-high heat.
15. Stir in the mushrooms, 1 teaspoon salt and pepper and cook, stirring occasionally, until the mushrooms begin to release some of their liquid, 4 to 5 minutes.
16. Stir in the garlic and nutmeg and continue to cook for another 2 minutes.
17. Sprinkle the flour over the mixture and stir to coat.
18. Cook for 1 minute.
19. Add the broth and simmer for another 1 minute.
