Onion Gratin

4 large yellow onions, peeled and sliced into 1/4 inch slices

olive oil

salt and pepper to taste

1 tsp. thyme, chopped

1 C. of heavy cream

1/4 C. of white wine

1/4 C. of parmigiano regginao (parmesan), grated

 

Spread the onion slices out in a baking dish and drizzle them with olive oil. Season with salt and pepper and sprinkle with the thyme. Bake in a preheated 375F/190C oven for 15 minutes. Meanwhile heat the heavy cream and wine in a saucepan until it starts to bubble on the edges. Transfer the onions to a baking dish and spoon the cream onto. Cover in foil and bake for another 25 minutes. Remove the foil and sprinkle the cheese on top. Increase the temperature to 450F/230C and bake until golden brown, about 5 minutes.
