Preheat oven to 350 degrees F. Sprinkle the beef bone-in short ribs liberally with salt on all sides. Place a large Dutch oven, over medium-high heat, and add the oil. When hot, add the short ribs and sear on all sides, until browned, about 10 minutes. You may need to do this in batches. Remove all of the short ribs and set aside.

Add the onion, carrot, celery stalks, tomato paste, cumin, garlic, sprigs of thyme, beef stock, soy sauce, flour and stir until combined. Transfer the short ribs back to the pot and transfer to the oven to bake for about 3 to 3 1/2 hours, until the meat is tender and falling off the bone.

Remove from the oven and serve on top of a bed of mashed potatoes.

Turn the sauté function on to high. In batches, add the bone-in beef short ribs to the Instant Pot and sear on all sides. This will take a good 15 minutes to do to get through all of the short ribs. Remove all of them from the Instant Pot and add the yellow onion, carrots, celery, tomato paste, garlic, thyme, beef stock, soy sauce and all-purpose flour. Mix until combined. And then add in the short ribs.

Turn the IP to “high” and set the time for 55 minutes. Allow a natural release for 15 minutes. Carefully remove the lid from the Instant Pot and remove a few short ribs and transfer them to a bed of mashed potatoes. Garnish with Italian parsley.
