Le Creuset Dutch Oven Question (1,364 views)

That's an interesting piece.  I'd be tempted to send a photo to Le Creuset and ask them for info.  It's sort of an upside down thing, but it's Le Creuset so it's also very cool.

It is a le Creuset discontinued pan = www.ebay.com/p/Le-Creuset-4-5-Quart-Cast-Iron-Cassoulet-Dish-CLOSEOUT/1600819082?iid=223372920249

The Le Creuset 4.5-qt. Cassoulet Dish is inspired by authentic French cassoulet dishes. This tapered design allows for more exposed surface area at the top, creating perfectly browned toppings for traditional cassoulet, pot pie, shepherd's pie and even a hearty confit. The story of the cassoulet begins in the 14th century, when citizens of the village of Castelnaudary fed this hearty dish of pork and white beans to French soldiers, who then fiercely defended the region and defeated invaders. Today, the cast iron dish that bears the same name is designed with a deep round contour and slanting sides that are ideal for slow cooking and extracting the full flavor of each ingredient. Many variations on the original cassoulet have recently emerged, including recipes with salmon, duck, mutton and goose.

Even heat distribution and superior heat retention
Colorful, long-lasting exterior enamel that resists chipping and cracking
Cast iron construction ideal for starting a dish on the stovetop and finishing in the oven
Used to make cassoulet, with more surface area at the top than the bottom to maximize crispness
Made in France, lifetime warranty; save to use on all cooking surfaces, including induction."

Great detective work emma!
I got curious and searched for cassoulet recipes. Then I landed on this site and baserati's precious estate sale find was pictured:

Still a lot of work so I'll follow soupandstew's suggestion and see if I can find it on a menu somewhere.
