Preheat oven to 400 degrees.
Peel onions; slice thickly.
Heat a grill pan until very hot; brush onion slices lightly with olive oil; grill 1-2 minutes on each side until slightly softened and have nice grill marks. Set aside.
In a saucepan, heat 1 T. butter over medium heat; stir in flour; cook 1 minute, stirring constantly. Pour in cream and sherry; whisk until smooth, stirring constantly while mixture comes up to a simmer and is thickened. Add nutmeg, garlic powder, salt and pepper, to taste.
Pour sauce into a cast iron skillet or a gratin dish; place onion slices over the sauce;
sprinkle the cheese evenly over everything.
Stir breadcrumbs with the remaining melted butter; add salt, pepper, and a few thyme leaves; sprinkle breadcrumbs over the cheese.
Bake about 20 minutes or until browned and bubbling. If desired, place the gratin under the broiler at the last minute if wanting extra browning.
