I have been doing fish and other frying in a large (9 quart) Le Creuset dutch oven and I like it so much I don’t use the old black cast iron anymore. There are a million cheaper versions out there as well which I would think would work just as well.
The La Creuset has all the advantages of cast iron because it is cast iron. The best part is that the enamel coating eliminates all the black cast iron pan issues with rust, seasoning, sticking, cleanup, etc. No need to be sanding, buffing, waxing, oiling, massaging, etc, etc, etc.
I also like the depth because there’s less spatter. Try it if you have one of these enamel dutch ovens.
I’ll be making a chuck roast and veggies in mine tonight. It’s my workhorse for stews, roasts, chili, soup, frying.
