Ossobuco Sous Vide Time and Temperature Experiment – Stefan’s Connoisseur Weblog

Ossobuco is a traditional Italian dish from Milan: braised veal shank, usually served with a saffron risotto on the aspect (which is the exception to the Italian rule that pasta or rice (primo piatto) shouldn’t be served along with meat or fish (secondo piatto)). I’ve been making ossobuco sous vide utilizing the advice by Modernist Delicacies of 62C/144F for 3 days, and that’s the recipe printed on this weblog. Nonetheless some Italians talked about they use 68C/155F, and I all the time thought that it was a bit dry at 62C/144F. So I made a decision it was time for one more side-by-side experiment to see for myself what works finest. The age of the calf may very well be an element to keep in mind. For these experiments I used ‘pink’ veal from calfs that aren’t greater than 8 months outdated.


Serves 2

  • 2 veal shanks
  • 1 bay leaf, 2 contemporary sage leaves, 1 sprig of contemporary rosemary
  • 1 carrot, 1 onion, 1 stick celery, all finely chopped
  • flour for dusting
  • 2 Tbsp olive oil
  • 1 Tbsp butter
  • salt and freshly floor black pepper
  • 60 ml (1/4 cup) dry white wine
  • 120 ml (1/2 cup) sieved tomatoes (passata di pomodoro)
  • 50 grams (2 oz) diced pancetta, optionally available

For the gremolata

  • 2 Tbsp minced contemporary flat leaf parsley
  • 1 minced garlic clove
  • grated zest of 1 untreated lemon


Place the veal shanks on a plate and season them with salt on each side.

Enable the salt to penetrate the meat for not less than a couple of hours, however ideally in a single day, coated within the fridge.

Make incisions within the robust membrane, reducing via the membrane however making an attempt to chop the meat beneath as little as potential, to forestall the shanks from curling up from browning them.

Pat the meat dry with paper towels, and mud with flour on each side. Warmth 2 tablespoons olive oil in a frying pan, and brown the shanks over medium-high warmth.

Brown them till they’re golden brown, about 1 minute per aspect. The within ought to stay uncooked.

Enable the browned shanks to chill off on a plate.

Add a tablespoon of butter to the pan through which you browned the meat, with out cleansing the pan first.

Sauté the carrot, celery, pancetta (if utilizing), sage, bay leaf, and rosemary within the butter.

When the greens are beginning to turn out to be golden brown, deglaze with the white wine.

Enable the wine to scale back to about half.

Then add the sieved tomatoes.

Enable the sauce to scale back till it’s good and thick. Throughout the sous vide cooking the meat will launch fairly a little bit of juices, whereas the sauce can’t scale back whereas it’s vacuum sealed.

There are three choices for bagging the meat with the sauce for sous vide cooking:

  • With a chamber vacuum machine: permit the meat and sauce to chill fully within the fridge, after which bag up and vacuum seal collectively.
  • With a ziploc bag and the water displacement methodology: may be executed whereas meat and sauce are nonetheless heat.
  • With an exterior vacuum sealer: freeze the sauce first, then vacuum seal the chilled (not frozen) meat along with the froze sauce.

The primary experiment I did was 72 hours at 62C/144F (like I’ve been doing earlier than) versus 24 hours at 68C/155F (as really useful by some Italians).

72 hours at 62C/144F was rather more tender and flaky than 24 hours at 68C/155F, and fewer dry as effectively.

My subsequent strive was 48 hours at 62C/144F verus 48 hours at 68C/155F.

At 68C/155F the meat now was tender sufficient, however nonetheless fairly dry. At 62C/144F the meat was much less tender after 48 hours fairly than 72 hours, as may very well be anticipated.

The ultimate experiment was 72 hours at 57C/135F versus 72 hours at 62C/144F. I attempted the decrease temperature to see if I might get the meat to be much less dry however nonetheless tender.

After sous vide cooking I decreased the sauce from the bag a bit to thicken it, and warmth it as much as serve on high of the meat to forestall it from cooling off too rapidly (which is required if the meat is cooked at solely 57C/135F or 62C/144F with out searing afterwards).

The consequence was that 72 hours at 57C/135F is to any extent further my favourite time and temperature mixture for ossobuco sous vide. It’s about as tender and flaky as 72 hours at 62C/144F, however clearly much less dry.

Ossobuco is garnished with gremolata, a mix of minced contemporary flat leaf parsley, garlic, and grated lemon zest.
