Conchiglie alla Vaccinara (Pasta with Oxtail Ragù Sous-Vide)

Coda alla Vaccinara is a classic dish from Rome: oxtail stewed in tomato sauce. It is usually served as a secondo, but you can also eat the sauce over pasta as a primo before that. Another less common variation is what I’ve done here: pasta with oxtail ragù, where the meat is chopped up and mixed with the pasta to create a very flavorful piatto unico.

Classic coda calls for stewing the meat until it falls off the bone. But now we have sous-vide and can make something special: medium oxtail that is very tender and juicy and still pink. It requires an exceptionally long cook of 100 hours at 60C/140F! The meat is very beefy and flavorful when cooked this way, and the only drawback besides the long cooking time is that it won’t fall off the bone so you will have to work a bit to separate the meat from the bones. (By the way, you don’t have to do anything during those 100 hours. Just vacuum seal the oxtail and put it in the sous-vide and then forget about it for 4 days.)

As I’ve shown in this post you can cook the oxtail sous-vide with the tomato sauce, and then the tomato flavor will penetrate all the way into the meat. For this version I decided to cook the oxtail separately and only mix it with the sauce in the end, and mixing the sous-vide juices with the tomato sauce. This makes for a more interesting flavor profile, because the oxtail stays more beefy inside the tomato sauce.

Finally a note on the pasta shape. In Rome the most usual pasta shape for this would be rigatoni. I thought that conchiglie rigate (ribbed pasta shells) would work even better, because they have the ideal shape to ‘absorb’ the pieces of oxtail meat in the sauce. But you can make this with any short pasta of your choice.

Ingredients

For 2 servings

About 600 grams (1.3 lbs) oxtail, cooked sous-vide for 100 hours at 60C/140F

250 ml (1 cup) peeled tomatoes, pureed in the food processor

80 ml (1/3 cup) dry wine

1 Tbsp raisins

1 Tbsp pine nuts

2 cloves

1 stick cinnamon

1 carrot, 1 onion, 1 celery stalk, minced

2 celery stalks

150 grams (.33 lb) conchiglie, or other short pasta

salt and freshly ground black pepper

olive oil

1 Tbsp minced fresh flat leaf parsley

Instructions

Season the oxtail with salt and freshly ground black pepper. Then vacuum seal, and cook sous-vide for 100 hours (96 hours or 4 days will be fine, too) at 60C/140F.

Use only meaty segments of oxtail and save the thin ones to make beef stock.

To make the sauce, heat 2 tablespoons olive oil in a frying pan. Add minced carrot, onion, and celery, and season with salt.

Add a tablespoon of pinenuts as well.

Stir over medium heat until the vegetables start to color, about 5 minutes.

Deglaze with 80 ml of wine (white or red are both fine).

Add a tablespoon of raisins, 2 cloves, and a stick of cinnamon.

Add 250 ml of peeled tomatoes, pureed in the food processor. Bring to a boil, then reduce the heat to a simmer. Simmer until the sauce has thickened, about 15 minutes.

In the meantime, peel the top of the 2 celery stalks to remove the tough fibers, and then cut them into slices.

Now take the oxtail out of the sous-vide. Cut open the bag, and add the juices to the sauce.

Bring to a boil again, stirring, then reduce the heat to a simmer again.

Meanwhile, bring a pot of water to a boil. When the water boils, add salt and the pasta. Set the timer for the time indicated on the package for al dente.

While the pasta cooks, take the meat off the bones (this is easiest with your fingers)…

…and chop it roughly.

About 3 minutes before the pasta is ready, add the sliced celery to the pot with the pasta.

When the sauce has reached a nice thick consistency…

…remove the cinnamon and the cloves.

Add the chopped oxtail meat…

…and stir to incorporate. Then turn off the heat, so the oxtail meat won’t overcook.

When the timer beeps, drain the pasta and celery, and add it to the sauce in the pan.

Toss to mix.

Serve at once on preheated plates, sprinkled with minced parsley.

Flashback

Shrimp with almonds and onions is a simple but very tasty appetizer that was inspired by something we tried in Croatia. The combination of the sweet earthy shrimp with the sweet onions and earthy almonds works very well. The garlic adds depth of flavor and it brightened up by parsley and just a drop of lemon juice.

  1. Do I see correctly that you pour wine onto a de Buyer pan? Once I tried doing that and it was a complete failure. The sauce I was making had a strange, “metallic” taste. The frying pan lost so much of the seasoning, that I had to re-season it. You haven’t had any of these problems?

    1. Well spotted, it is a de Buyer. I have not had such a problem. In the user manual it says that white spots can appear after using acidic ingredients like wine or tomatoes, and that you should season again if that occurs. Perhaps your pan was very hot and/or you used a lot of wine and/or your seasoning was thin and/or you did not have enough oil in the pan?

      1. I was trying to deglaze the pan after searing a rack of lamb. So there wasn’t a lot of oil there, only the rendered fat and yes, I used quite a lot of wine (and lamb stock after that).
