Osso Buco in an Instant Pot, with mashed potatoes, easy and fast and incredibly delicious. We did our browning in a separate skillet. You can do it in the Instant Pot if you like to hover, but we couldn’t get both shanks to fit at the same time. In true Carol fashion, this recipe is a mash up of traditional Osso Buco and a new Instant Pot recipe. So, pulled from a few different recipes and tweaked to our liking, here is our Instant Pot Osso Buco.

2 - 10 ounce beef shanks olive oil
4 baby carrots, quartered lengthwise
1 celery stick, cut in thirds and then quartered lengthwise
1 yellow onion, diced
1 cup chicken stock
1/4 cup dry white wine
Polenta or risotto, or mashed potatoes.

Add olive oil to skillet and heat over medium high heat. Add in shanks, lying flat, and brown on both sides. Once browned remove and place in Instant Pot.

Add carrots, celery, and onion to skillet and sauté until tender, about 5 minutes. Put vegetables in Instant Pot.

Deglaze pan with white wine and chicken stock, then transfer to Instant Pot.

Set Instant Pot Pressure to high and braise for 45 minutes. Then release natural Pressure for 15 minutes.

Release any remaining pressure and serve, one shank per person. We served with Polenta, but since you are using an Instant Pot, we recommend Mashed Potatoes if you need a break.
