1-Getting started with this one pot lamb shanks recipe: is simple, and it begins with prepping your ingredients. First, trim the lamb shanks of any excess fat to ensure a cleaner final dish. This step helps the meat absorb flavors without becoming greasy.

2-Next, heat 2 tablespoons of olive oil in your Instant Pot on sauté mode. Sear the lamb shanks for 7-10 minutes on all sides until they develop a nice golden color. This browning locks in the juices and adds depth to the overall taste.

3-Then, in the same pot, cook the chopped onion until it’s caramelized, which takes about 5 minutes. Add the chopped carrots, celery ribs, and smashed garlic cloves, stirring them to release their aromas. Follow this by stirring in 2 tablespoons of tomato paste and cooking for another minute to enhance its flavor.

4-Pour in 2 cups of red wine and let it reduce by half, concentrating the flavors. Mix in 1 cup of beef broth, 1 teaspoon of dried thyme, 1 teaspoon of dried oregano, salt to taste, and 2 bay leaves. Return the lamb shanks to the pot, making sure they’re submerged in the liquid for even cooking.

5-Cooking and Finishing Steps: Set your Instant Pot to high pressure and cook for 50 minutes. After that, allow a 10-minute natural pressure release before carefully opening the pot. Remove the meat and cover it to keep it warm while you thicken the sauce.

6-To finish, simmer the remaining liquid on sauté mode and add a slurry made from 1 tablespoon of cornstarch mixed with a little water. Stir until the sauce reaches your desired thickness, creating a rich and flavorful coating for the lamb.
