Instructions
Let 6 pounds bone-in beef short ribs sit on the counter for 30 minutes to allow them to come to room temperature.
Preheat your Instant Pot by pressing the Sauté button
Once the Instant Pot displays ‘Hot’ add 1 tablespoon vegetable oil.
Generously season meat with salt and pepper and add half to the Instant Pot.
Turn meat to brown on all four sides (about 2 minutes per side). Repeat with the remaining half. Transfer short ribs to a plate and set aside.
Leave the drippings and fat from the sear in the Instant Pot and add the remaining 2 tablespoons of oil along with the onions, carrots, and chopped celery. Sauté for 5 minutes or until slightly browned.3 cups chopped onions, (about 3 medium onions), 3 cups peeled and chopped carrots, (about 3 medium carrots), 1 cup chopped celery, (about 2 stalks)
Sprinkle ¼ cup all-purpose flour over the vegetables and add 2 tablespoons tomato paste. Stir and let the mixture cook for about 3 minutes until evenly coated and a nice deep color appears. Scrape up any accumulated browned bits at the bottom of your pot.
Add the bottle of red wine, and short ribs to the Instant Pot and bring to a boil.
Add sprigs of fresh herbs, garlic halves and the stock to your pot
Cover the Instant Pot and set it to high pressure for 45 minutes with a 15-minute natural release (look to the user manual for instructions on operating the high-pressure setting).
While your ribs are cooking, prepare your gremolata by combining all ingredients into a small mixing bowl and set aside.
Carefully open your Instant Pot as per the user manual and discard the garlic, bay leaves, and herb sprigs.
With a slotted spoon, transfer the meat to a platter.
To make the gravy, strain the liquid from the pot through a fine-mesh sieve into a medium-sized bowl and skim off any fat that has surfaced. Season with salt and pepper to taste.
Serve ribs with gravy and gremolata over mashed potatoes.
Notes
Meat that has rested on the counter and had a chance to warm up a bit, will make for a better sear and brown nicely as opposed to cold meat.
It is okay if your ribs get very dark when searing/browning them – the darker, the deeper the flavor! Be sure to scrape up any browned bits at the bottom of the pot, as they add more flavor and richness to your gravy.
If you want to thicken your gravy up a bit, simply add 2 tablespoons of cornstarch to a measuring cup along with ¼ cup of the sauce from the pot. Stir until well mixed, then return the mixture to the pot and continue stirring until it is fully incorporated.
