How do cooks prepare risotto in a restaurant?

It's actually hard to hold when it's almost all the way cooked - it'll start getting gluey if you let it cool off, but could start scorching on the bottom if it's not stirred, and get too runny if you keep adding stock.

Mario Batali said that risotto isn't finicky in the middle - so you can cook it part way, cool it down (I think he said he spread it on sheet pans to cool quickly), then you can add hot stock and cook it from that point, so you've already got a 10 minute head start.

I've also been to a restaurant where it was only served on the hour and half-hour.

I am a cook in an Italian restaurant. We cook risotto to order, from scratch in under 20 minutes.

You need a hot pan, hot stock and a hot French top/burner.

It's easy. Add onion, butter, olive oil, salt and pepper, sweat the onion (it in your already hot pan). Add rice, toast and deglaze the pan. add stock, cream, salt. Come back in 10-15 minutes (All that stirring is actually not necessary). Add your veg, stock, salt. Finish with cheese and butter.

You need 18-20 minutes for perfect al dente risotto.

Risotto can linger for a while and be plenty tasty, and it reheats fine if you add some liquid. Arborio is tough as nails, and can withstand a ton of abuse. If it were me, I'd cook it until it's about 75% finished, and then cool it.

Then you could just slop it out in a skillet and finish it off in a few minutes with a little more broth and some grated parmesan.

I've read a lot of people say, however, that it can't be done without the risotto devolving into a blob of starch. Some people add cream to slow down the arborio's ability to absorb liquid. I think though, that it wholly depends on your crowd. If you're serving at a nice restaurant, held over risotto is probably not going to cut it.

I've been told by an Italian chef that Carnaroli rice is often used in restaurants due to its ability to stay solid longer than any other strain of rice. I suppose that when using Carnaroli you could indeed cook it almost all the way through, then finish the dish with some more broth.

You could also make all the preparation, e.g. sautee the onions, vegetables, etc, so that when a dish of Risotto is ordered it can be ready in 20 minutes. Some restaurants I've dined in warn you when you order Risotto that it takes a while to prepare...

Par cooking, if done properly, will not change the texture of the rice. The key is to cool quickly! Then make sure stock is very hot and rice is at room temp when finishing off. This will basically pick up the cooking process exactly where you originally left off at since you cooled it quickly thus limiting the continuation of the cooking process. Biggest mistake would be assuming that the amount of time to finish is just picking up at the time stopped without realizing that the rice, if not cooled quickly, has continued cooking after you stopped and then you overcook it, hence it becoming mushy. If you don't make this assumption and test your rice you will be fine without loss of quality.

Bourdain, who loves gabbing about tricks like this says that you can spread it out in sheet pans and cool it when 'partway' done in his Les Halles cookbook. I think this is a sensible plan of attack, especially because I usually need 45 minutes to make Risotto, not 20.

That said, I haven't tried it, so I can't personally comment. I bet there are some easy sous vide applications here as well; I'd be interested to get a comment from a chef on that.

There seems to be some fanfare for par cooked risotto. What happens once cooled, the grain will heat up much faster on the outside than the inside and will absorb the extra liquid far quicker creating a mushy outer layer on each grain which will still needs to be cooked at the inner core.

The single biggest factor with the final flavor and texture is the initial saute or roast of the grains before the liquid is added. Add diced onion and olive oil to a pan and heat a little before adding the rice. During the saute each grain will become translucent on the outside and at the ends while the middle will still be white. The rice will also start give off a strong aroma. This aroma will carry to the final product. If the rice is cooked too hot or too long at this stage it will lose the aroma and will not absorb liquid correctly, creating a soggy outside and hard inside.

I would gladly face any master chef in the world in the Iron Kitchen for Battle Risotto if they had the handicap of having to cool their product and reheat it while I can, without stopping, go from start to finish on the stove top. I would surely win no matter what other ingredients they put in it.

EDIT: I would in Iron Kitchen make a type of Paella which I believe made with a short grain rice is the single most technical dish in all of European cooking for added points in technique. How it's done.

I've worked with a solution that I did not see mentioned here.

We served risotto every half hour. This was in a shared-plate restaurant, so it worked really well. Even if a table ordered a risotto at the very beginning of a new batch, we could always buy time on the table with appetizers, salads, etc.

Other answers here suggest that you can par-cook risotto or cook it without movement. This is true, but in my experience, a great risotto needs frequent movement, cannot be rushed, and has a very short shelf life.

So I believe that the other answers here are correct, but I would say that (and I apologize for stepping on any toes there) most restaurants don't serve very good risotto.

I save time on homemade risotto by actually putting the rice in the rice cooker and cooking it until done. It's never disintegrated on me while finishing the risotto because it doesn't cook any longer, it's just reheated from the stock which isn't boiling and is in the pan no longer than a few minutes on low to medium heat. I use this method so I don't have to babysit risotto for 20 to 30 minutes and use the time preparing other menu items.

I made risotto last night, the conventional way which lead me to this question of how restaurants made it so quick. I take it that you partially boil the rice in stock, not water. I don't see where anyone mentions that major detail.
