Green Bean Casserole

Heat the oven to 190 C. Boil green beans in water seasoned with salt for 5 minutes until bright green and crisp-tender, then plunge into ice water and drain well.

Melt butter in a large skillet and cook mushrooms and onion until the mushrooms are browned and dry, about 8 minutes. Add garlic and all purpose flour for 1 minute, then whisk in vegetable broth and whole milk and simmer until thick. Season with salt, black pepper and nutmeg.

Fold blanched beans and half of crispy fried onions into mushroom sauce and spread in a 20 x 30 cm baking dish.

Bake assembled casserole for 20 minutes until bubbling, then scatter the rest of the fried onions on top and bake 5 minutes more until golden.
