With the flattest side of the onion down, slice off the top. Use a spoon to carefully scoop out the inside of each onion, leaving a good layer of flesh around the perimeter, being sure to leave the bottom intact. Reserve the scooped out bits.
Rub each onion, inside and out, with a little olive oil, and season well with salt and pepper.
Set your onions in the baking dish and cover loosely with foil. Bake for 25-30 minutes.
Meanwhile, measure out 1/2 cup of the reserved onion flesh and finely chop it. Heat 1 tablespoon olive oil and 1 tablespoon butter in a saute pan and saute the garlic, shallot, and chopped onion for about 7-8 minutes, until softened. Add a splash of white wine to the pan and cook until absorbed.
Take off the heat and add the herbes de Provence, bread crumbs, Parmesan, and thyme. Add salt and pepper to taste. Mix well.
Fill the onions with the stuffing. Press lightly to fit the stuffing tightly in the onion cavity and then mound it up a bit on top. Dot with butter.
Pour white wine into the baking dish to a depth of just 1/4 inch. Cover loosely with foil and bake for another 30 minutes, or until the onion is completely tender. The exact time is going to depend on the size and shape of your onions. Check with a small sharp knife, it should slide in without resistance.
