I have two Staubs and a $40 enameled cast-iron Dutch oven I bought at Target. I use them interchangeably with no real notice of difference. The Staubs seem to be holding up better–the Target one (which doesn’t have the brand name on it. Or, if it did, it was on the handle which I replaced with a metal one, since I was using it at 500 degree temps in the oven) has minor scratches along the inside bottom’s enameling, but performs just as good as the Staubs. The Staubs don’t have any enamel on the inside, just cast iron, so I can’t really compare, but they look as good as the day I got them as a gift from my considerate brother.
I’m sure she loves you forever already, but you really can’t go wrong with the gift of a LeCreuset or Staub. If I were buying for myself, I’m not sure whether I’d spring the premium on them or not, though. I’d probably just go with a Lodge. As a gift? The others.
