Heat oil in a very large saute pan over high heat until smoking hot. Add onions and let brown well before moving about 2-3 minutes. You want the onions to caramelize but not burn. Allow to caramelize on all sides about 6-8 minutes total. If you feel the onions are burning reduce the heat to medium-low. Place the onions in a greased casserole dish and set aside. In a small bowl whisk together cream eggs and garlic and season with salt and pepper. Pour custard over the caramelized onions. In another small bowl mix bread crumbs and parmesan cheese. Spread the bread crumbs over the top of the onions. Place in a 350 degree oven
