  • Spray a 2 1/2-quart casserole dish with cooking spray. Mince shallots until you have 3 tablespoons; slice remaining shallots into 1/8-inch rounds. Set both aside.
  • Bring a large pot of lightly salted water to a boil. Add beans and cook until tender but still crisp, about 4 minutes. Drain, rinse, and pat dry; set aside.
  • Melt butter in a saucepan over medium heat. Add mushrooms and cook, stirring frequently, until browned, 5 to 7 minutes. Add minced shallots and cook until softened, 2 to 3 minutes. Stir in 3 tablespoons flour, then slowly add half-and-half, broth, and soy sauce. Bring to a boil while stirring.
  • Reduce heat to a simmer and stir until thickened, about 5 minutes. Stir in green beans and season with salt and pepper. Transfer to the prepared casserole dish, cover, and refrigerate 8 hours to overnight, or until ready to bake.
  • Preheat the oven to 350 degrees F (175 degrees C).
  • Remove casserole from the refrigerator and bake in the preheated oven until heated through and bubbly, about 30 minutes.
  • While the casserole is baking, dredge shallot rings in remaining flour until evenly coated.
  • Heat oil in a saucepan over medium heat. Lower shallots carefully into the hot oil, working in batches if necessary. Fry until golden brown, 1 to 2 minutes, then drain on paper towels.
  • Remove casserole from the oven and top with fried shallots.
