Instructions
Preheat the oven to 375°F.
In a large pot, bring a gallon of water and 2 tablespoons of salt to a boil.Add green beans and blanch for about 3-5 minutes depending on the size of green beans or until bright green and halfway to tenderness. Drain and place in an ice-water bath to stop cooking. Drain and set aside.
In a large skillet over medium-high, heat the oil and cook sliced mushrooms, undisturbed for 2 minutes, and continue to cook, stirring, until they are soft and most of their liquid has evaporated for about 4-5 minutes.
Melt butter and add flour, cook and keep stirring for 1-2 minutes or until roux is golden brown and smells mildly nutty.
Add garlic powder, dijon mustard, onion powder, black pepper, salt, and nutmeg. Stir for 1 minute.
Add chicken broth, simmer for 1-2 minutes.
Add heavy cream, reduce the heat and simmer for 6-8 minutes or the sauce thickens and coats the back of a spoon. Stirring occasionally. Remove from the heat.
Add the blanched green beans and stir to coat in the sauce. Transfer the mixture to a 3-quart or 9'x13' baking dish then layer French fried onions on top.
Bake for 20 minutes or longer until hot and bubbly.
