- 3 cloves garlic, minced
- 10 oz cremini mushrooms, thinly sliced
- 3 tbsp all-purpose flour

- 1 tsp soy sauce
- ½ tsp black pepper
- ¼ tsp freshly grated nutmeg
For the topping
- 2 ½ cups crispy fried onions (one 6 oz can), divided
Instructions

Preheat the oven to 375°F (190°C). Bring a large pot of generously salted water to a boil. Add the green beans and cook for 5 minutes, until bright green and just barely tender but still with a firm bite. Drain in a colander and set aside.
