Preheat the oven to 375 degrees F.
Heat the olive oil in a small skillet over medium-high heat until very hot but not smoking.
Add 1/4 cup shallots and cook, stirring, until golden brown and crisp, about 2 minutes.
Transfer with a slotted spoon to paper towels to drain.
Repeat with the remaining shallots, cooking 1/4 cup at a time.
Reserve the oil in the skillet.
Place the green beans in a steamer basket fitted over a pot of boiling water.
Cover and steam until bright green and still crisp, about 3 minutes.
Heat 1 tablespoon of the reserved shallot oil in a large, deep nonstick skillet over medium-high heat.
Add the 🍄 and cook, stirring occasionally, until the 🍄 liquid is evaporated and they begin to brown, about 12 minutes.
Add the garlic and thyme and cook, stirring, 1 minute.
Transfer the 🍄 mixture to a bowl.
Whisk together the milk and flour until the flour is dissolved.
Add the mixture to the skillet and, whisking constantly, bring to a simmer.
Reduce the heat to medium low, whisking occasionally, until thickened, 10 to 15 minutes.
Remove the pan from the heat and stir in the green beans, 🍄 mixture, 1/3 cup parmesan cheese, the parsley, nutmeg, 3/4 teaspoon salt and 1/2 teaspoon pepper.
Coat a 2-quart baking dish with cooking spray.
Spoon the green bean mixture into the prepared dish and sprinkle the top with the crispy shallots and the remaining 2 tablespoons cheese.
Bake until golden on top and bubbling, about 20 minutes.
