In a skillet, melt the butter. Add the sliced mushrooms. Sauté until they have released their liquid and start to turn golden brown.

Sprinkle flour over the mushrooms. Stir for a minute then gradually pour in the milk while whisking. Let thicken over low heat until the sauce coats the back of a spoon. Stir in cream, salt, pepper, and nutmeg.

Frequently asked questions
How do you get this dish right?
- Do not overcook the beans in water; they will finish softening in the sauce in the oven.
- If the sauce is too thick, thin it with a splash of milk before baking.
- Add the fried onions only for the last 5 minutes to prevent them from burning.
How long does this dish keep?
Keeps for 3 days in the refrigerator. Reheat in the oven to maintain the crunch of the onions.
