Directions: Preheat oven to 325 degrees. Heat the olive oil in a small saut, pan and add the pancetta. Saut, until crisp, about ten minutes. Set aside. In a large saut, pan, heat the 2 T. of butter and add the sliced onions. Cook over low heat, stirring often for about 30-35 minutes until onions are golden. Cook the angel hair pasta and combine with the cooked pancetta and caramelized onions. Add the eggs and parmesan cheese. Mix well to combine. In a heavy skillet, melt the 1/4 cup butter. Add the pasta-egg mixture and cook over low heat until the eggs firm up, about 8-10 minutes. Then place the dish in the oven and bake for 10 minutes. Serves 6.
