Toss thinly sliced onions with flour, panko, and coarse salt until evenly coated. Spread onions on a prepared baking sheet, give them a spritz of olive oil and bake for 25-30 minutes, stirring every 8-10 minutes.
In a large oven-proof skillet, melt butter. Add the diced pancetta, mushrooms, salt, and pepper. Cook, stirring often, for 4-5 minutes. Add garlic and nutmeg.
Sprinkle flour over mushroom mixture, add stock and simmer. Add half and half and water chestnuts. Cook until it thickens, stirring occasionally, about 6-8 minutes.
Remove skillet from the heat, stir in the green beans and ¼ of the onions. Top with the rest of the onions and bake at 400F for 15 minutes.
