Start by patting the short ribs dry and seasoning them with salt and pepper. Heat a bit of oil in your Dutch oven over medium-high heat. Sear the ribs for about 3 minutes per side until they’re beautifully browned. Remove them from the pot and set them aside.
Lower the heat to medium-low. In the same pot, add the diced carrots, celery, and onion. Season lightly again with salt and pepper. Stir occasionally and let these cook for 15 minutes until they’re soft and fragrant. Now toss in the minced garlic and cook for another minute or so.
Add the tomato paste and stir it through the veggies. Let it cook for about 3 minutes—it will darken and smell amazing. Then pour in the red wine and stir frequently, letting it reduce for about 5–7 minutes.
Add the crushed tomatoes, beef broth, rosemary, thyme, and bay leaves to the pot. Stir it all together and bring it to a gentle boil. Nestle the short ribs back in and lower the heat to a soft simmer. Cover and let everything cook for about 2.5 to 3 hours.
Once the meat is fork-tender, remove the ribs from the pot. Discard the bones and shred the meat using two forks. Return the shredded beef to the sauce. Let it simmer uncovered for another 20 minutes, reducing the sauce to a thick, luscious consistency.
On low heat, stir in the cream and grated Parmesan. This brings everything together into a silky, luxurious sauce.
Cook your pappardelle pasta in salted water until al dente. Save some of the pasta water before draining. Add the cooked pasta to your ragu along with a splash of pasta water. Stir until the sauce clings to the noodles and has that glossy, creamy finish.
