Ingredients
1.5 pounds French green beans, ends trimmed
1 cup shallots, thinly sliced
3 tablespoons flour, divided
8 ounces mushrooms (shitake and baby bella or mixed), sliced
2 tablespoons butter
2 garlic cloves, minced
1/4 teaspoon freshly grated nutmeg
1/4 cup dry white wine
1 cup vegetable broth (or chicken)
1 cup half and half
Instructions
  1. Preheat oven to 375 degrees.
  2. Wash and trim green beans. Blanch in boiling, well-salted water. Immediately transfer to ice water bath and set aside.
  3. Heat 1 to 2 inches of vegetable oil in a deep, medium skillet.
  4. Pat shallots dry, then toss with 1 tablespoon of flour. Season with salt and pepper. Fry shallots in oil (in batches) until golden brown, then transfer to a plate to drain on a paper towel.
  5. Melt butter over medium heat in a medium pan or cast iron skillet. Add mushrooms and saute until mushrooms are golden brown.
  6. Add garlic and nutmeg and cook for another minute or two. Add 2 tablespoons of flour and cook for 1 minute.
  7. Slowly add white wine, cook for a minute and stirring to break up any flour lumps. Slowly add vegetable broth and bring to a boil. Boil the mixture for another 2 minutes, then turn the heat down to medium-low.
  8. Add half & half and cook, stirring, until mixture begins to thicken. Take off heat.
  9. Add green beans to mushroom mixture. Add 1/4 cup of the fried shallots. Mix to combine and season to taste with salt and pepper. Transfer green bean casserole to a 9x9 baking dish or bake in cast iron skillet. Sprinkle remaining shallots on top or around edges of casserole.
  10. Bake for 20 minutes until green beans are warmed and mixture is a little bubbly.
