No, you could use that piece as a Dutch Oven. I use skillets in the oven all the time. (stainless steel ones). But I do love my LC Dutch ovens!

Well, according to Larousse Gastronomique, the "The World's Greatest Culinary Encyclopedia", a Dutch Oven is:

"A large heavy cooking pot with a close-fitting lid, authentically made of cast iron and hung over an open fire. Thought to be of 16th Century Pennsylvania Dutch origin, the pot was used for stewing and braising; however, other types of dishes, such as breads, were also cooked in it. In modern terms, it is sometimes used for glazed pots for cooking in the oven or on top of the stove."

So, although cast iron is the "authentic" material, I think the key is "large heavy cooking pot with a close fitting lid". Little cooking is done over an open fire in modern times, so the pots can be made of other, more modern materials but the use remains the same.

I think what you have is a dutch oven. An Amazon search shows me that the large percentage of dutch ovens are cast iron, but they are also available in stainless steel and aluminum.

What brand is the one with the black handles? I sure would bet it will go into a 425 oven just fine....and I never cook anything that hot in my dutch oven..in the oven.
A stock pot is thinner, more likely to scorch on the bottom....meant for top of the stove simmering not for long slow cooking on the stove top.
You can get a dutch oven in Calphalon in Magnalit, in lodge cast iron and in many brands of enamelled cast iron.
Tell your husband to be careful of the enamelled pah...and if he does a lot of cooking he will love it and take care of it.

Linda, that pot is Lifetime/WestBend. I know it could go in the oven on lower temps (the stew I made today only needed 300F degrees. I just won't put a pot in the oven with those types of handles. I've seen other people's cookware that has been used that way and over time the handles crack and wrinkle. And I just don't like the idea of any type of plastic in the oven. I know "they" say they are safe, but it's just one of my quirks.

Donna, I have that Cuisinart pot in the 12 qt. version. I was hoping to do long simmers of spaghetti sauce in it but that didn't work out. Sauce burned too easily on the bottom. So it is billed as and behaves like a stockpot.

I don't know how it would behave in the oven but would not expect it to be a good substitute for a Dutch oven.

ci_lantro, I ordered the pot last night, so we'll see. I was not unhappy with my Stockpot performance in the oven, it just lacked a lid. Its performance on the stove burner (electric) was a disappointment, though. As per your experience with sauce, after browning the meat, then browning the vegetables, the bottom burned more than I would have liked. I think that the thicker bottom on the one I ordered may make a difference.

A great deal of the measure of the "goodness" of a Dutch oven is how tightly the lid fits.
My litmus test is a pot roast, you should be able to brown the meat and add a small amount of stock or wine, pop on the lid and keep it at the very lowest simmer for about 2 1/2 hours and not have to worry about the liquid cooking away....in an ideal world! In the real world even my Le Cruset has to have an extra splash of something after about an hour and a half.

Cast iron like LeCreuset or Staub is actually cast, as in molten iron poured into sand. If it doesn't come out true, they throw it in the scrap pile, and reuse the iron. Still, this is artisanship rather than computer-factory marvel and the lids fit, but not always perfectly tight. The thing that makes them "ovens" (LeCreuset changed the wording to "French oven" because too many new customers didn't understand the long use of "Dutch oven" as Annie explained it.) Lodge looks more like it's made in some kind of die mold nowadays. Very thick and mechanical looking.

The thing that makes it an "oven" is the poor conductive qualities--i.e., good insulating qualities--of the cast iron or ceramic. In fact, the very best actual ovens for baking and roasting are cast iron or ceramic, too. The heat is even and gentle.

In the case Linda described, where you're braising with low liquid, the traditional thing to do with your well fitting, but not sealed against steam, lid is to wrap the connection between lid and pot with pastry. Often it would be the scraps mushed together and formed into a belt shape, but making a quick dough of flour and water is no big deal if there are no scraps. Think Play-doh. That still works really well, though nowadays people are more likely to use silicone or parchment paper.

My new pot arrived yesterday and although I haven't used it yet, I'm already impressed. Amazon's title for the sale had it as a stockpot. The box labeled it as a saucepot. The stockpot I posted a picture of weighed 1.8 pounds sans lid. The new pot weighs 2.9 pounds sans lid, even though it holds less than the other pot. I knew to expect that the base would be thicker because of the encapsulated aluminum, but even the walls of the pot are thicker. And the lid has a nice heft to it as well. I might just have to make Serious Eats All-American Beef Stew again this weekend. To me, it was an unusual combination of ingredients, but they really worked (chicken broth instead of beef broth, soy sauce, Worcestershire sauce and FISH SAUCE!)

I have an all-metal Dutch oven like the one in the last photograph, but I only use it for deep frying, and not very often for that. I kept hearing and reading about them so much that I thought I needed one, but I never braise anything or make roasts, and so I probably did not need it.

I think you got the right one.

I make stock in my pressure cooker, and I use my stock pot only for boiling water for pasta, but that is fairly frequently. We do tend to cook outdoors a lot, as in olden times, but mainly grilling, which may be why I do not make roasts.
