Heat the olive oil in a large heavy bottomed pot or Dutch oven over medium heat. Season the beef generously with salt and pepper, then add it to the pot in a single layer. Cook, turning occasionally, until browned on several sides, then transfer the meat to a plate and set aside.
2 tablespoons extra virgin olive oil, 1 ½ pounds beef chuck, kosher salt and freshly cracked black pepper
Add the carrot and celery along with a pinch of salt. Cook, stirring, until softened, about 5 minutes.
¼ cup carrot, ¼ cup celery
Add the sliced onions, bay leaves and another pinch of salt. Stir well to coat everything in the oil, then add ½ cup of water. Cover and reduce the heat to medium-low.
2 ½ pounds yellow onions, 3 bay leaves
Cook, stirring every 5 minutes, until the onions have softened and released their liquid, about 20-30 minutes.
While the onions cook, preheat the oven to 325°F.
Uncover the pot and add the white wine. Nestle the beef back into the pot along with the marrow bone, if using, then cover completely with onions.
¾ cups dry white wine, 1 small beef marrow bone
Cover the pot, then transfer to the oven and cook for 1 hour.
Give everything a stir, then add the cherry tomatoes and the Parm rind if using. If a lot of liquid has evaporated and the pot looks dry, add a splash of water.
¼ cup cherry tomatoes, 1 Parmigiano Reggiano rind
Cover and return the pot to the oven for an additional 2-3 hours, checking and stirring halfway through. Add more water as needed to keep it moist. It’s done when the onions are very soft and jammy and the beef is easily falling apart.
Remove the beef and set aside to cool slightly, then remove the Parm rind, bay leaves and marrow bone. If using a marrow bone, scoop the softened marrow into the pot and discard the bone. Mix in the marrow so it’s fully incorporated into the sauce.
Shred the beef while it’s still warm, then return it to the pot and stir to combine. Taste and adjust with more salt and pepper as needed.
Bring a large pot of well-salted water to a boil. Cook the pasta until al dente. Reserve about 1 cup of pasta water, then drain.
Add the pasta directly to the sauce along with a splash of pasta water. Cook over low heat while stirring and tossing constantly.
1 pound ziti
Add a little bit of grated Parmigiano Reggiano, a little bit of parsley if desired and more pasta water as needed, then continue tossing until the sauce clings to the pasta and looks cohesive.
Parmigiano Reggiano
Serve hot with a drizzle of extra virgin olive oil and plenty of freshly grated Parmigiano Reggiano.
