Use cast iron pot on gas grill?

  • 8

Hi everyone!
Does anyone know if you can use a cast iron pot (I have a Le Creuset) on an outdoor gas grill?

I can't stand frying onions in the house this time of year when you can't open the windows. The whole house stinks and forget about doing laundry and cooking at the same time. Someone suggested that I should try cooking the stinky parts of the dish on the grill outside and finish it off inside the house. Sounds like a great idea, as long as it's not snowing or raining, but I don't want to risk ruining my Le Creuset. I think it's the most valuable thing in my kitchen! Has anybody tried this?

  1. people cook on gas burners all the time.. so I see no reason why not. Cast iron was originally used over wood fires in fireplaces and campfires (albeit it wasn't enameled cast iron).

    I wouldn't use too high of a heat (why would you anyway?), and things should be fine. For the future I'd use an inexpensive cast iron skillet for outdoor cooking (macy's has the martha stewart 10" skillet on clearance for extremely low prices -- I purchased one xmas week for $3 and change).

    1. A regular cast iron pot or pan (non-enameled) can be used on most cooking surfaces.

      I would not trust an enameled pot, however, as the hot/cold temperature changes can make the enamel more brittle and even if that were not an issue, the exterior might char and be a pain to clean.

        Also, if you choose to follow the advice of the 2 previous posters, which I would also recommend, you can season your unenameled cast iron on your grill as well. After one day of seasoning, you should be ready to fry onions outdoors to your heart's content

      2. You can definitely put LC on the gas grill. I do it all the time. Just make sure the grill is clean - if you've got drippings from your last batch of hamburgers on the burners, it will make oily smoke that can deposit a fair amount of unsightly gunk on the outside of your pot, making cleanup a chore. Also, if you're going to lid up the pot and close the grill cover, watch the temperature - the pot can withstand high heat, but the plastic knob on top will start to melt around 450F.

          Thank you all for your input. And for pointing out that the plastic knob might melt - I didn't think of that. I think I'll just get a non-enamel pot and try it out. I was looking at the Lodge Logic Double Dutch Oven, 5 Quarts... 20 lbs though..! I better use it while I'm still young enough to be able to handle it! :-)

            This is great news to me! While I enjoy eating it, I rarely make fish because I hate the smell of it in my very small house. It is some beautiful weather here today and I made a stop in the fish market and was hoping to find out that I can use me LC on my gas grill. I have to admit I have to LC skillets that I am not too fond of and rarely use (although the LC dutch oven is my workhorse) so if they get roughed up a little it is fine with me.Thanks for the input!

              I wouldn't use enamel ware on a grill unless I was okay with crazing and chips falling off.
              If you don't like your LC skillets, sell them on craigslist then use the money to buy a relatively cheap CI pan and pocket the rest of the cash for a rainy day.

          2. FWIW, I use LC and regular cast iron in my wood-fired oven all the time, typically 800-1000F. That's quite a bit hotter and exposes it to direct flame which you probably won't have on a gas grill. I've never had a problem, although the exterior enamel on my LC ends up needing some attention with the Barkeepers Friend afterward.
