Carmelized Onion Tart

"My caramelized onion tart is buttery, flaky, and filled with a creamy flavorful filling. It is elegant enough for dinner parties but easy enough for busy weeknights.I love decadent side dishes like my loaded mashed potato casserole, hush puppies and mashed potato cakes . Another side dish I cook often is this onion tart. It tastes like French onion soup but is easy to slice and eat while mingling with guests. The slow cooked onions become so sweet and flavorful, and the filling is rich without every feeling heavy. "
