- 2 tbsp unsalted butter
- 250 g (9 oz) cremini or button mushrooms, sliced
- 1 small yellow onion, finely chopped
- 2 garlic cloves, minced

Instructions
- 1. Preheat the oven to 180°C (350°F).
- 2. Bring a large pot of salted water to a boil. Add green beans and cook for 5 minutes until just tender but still bright green. Drain and immediately rinse under cold water to stop cooking. Set aside.

- 5. Add the drained green beans to the skillet and toss to coat evenly in the sauce.
- 6. Transfer the mixture to a 2-liter (2-quart) baking dish. Sprinkle half of the crispy fried onions on top.

- 8. Let cool for 5 minutes before serving.
Zusatztipps für die Zubereitung
To enhance the sauce, consider stirring in 50 g of grated sharp cheddar or Gruyère cheese just before adding the green beans. This adds a deeper flavor and richer texture. For ease, you can prepare the casserole up to step 6, refrigerate it for up to 24 hours, then add the final topping and bake when ready to serve.
Varianten und Anpassungen
If fresh green beans are not available, frozen cut green beans work well when thawed and drained. For an extra nutty flavor, sprinkle a pinch of freshly ground nutmeg in the sauce. You may also make your own crispy fried onions at home for a more personalized touch.
