Step 2

Press the "Saute" button on the Instant Pot. Press "Adjust" and select "More" setting. Once the display says "Hot", add the olive oil and allow to heat.

Step 3

Once the oil is hot add the chicken skin-side down. Saute without moving until golden in color, 7 minutes. Flip and cook 2 minutes. Transfer to a clean plate.

Step 4

Add onions and tomatoes, saute until tender, 3 minutes. Add garlic and saute for 30 seconds.

Step 5

Add chicken broth, balsamic vinegar, ½ teaspoon salt and thyme, stir to combine.

Step 6

Add chicken to the pot. Place lid on Instant Pot and turn to lock. Make sure the steam release handle is positioned to "sealing". Press the "Keep Warm/ Cancel" button.

Step 7

Select the "manual" setting on "high pressure". Use the "- or +" button to adjust the time to 10 minutes.

Step 8

Step 9

Once the display indicates "On" and begins the countdown at "10", and beeps when the cycle is complete.

Step 10

Cover your hand with an oven mitt or towel to carefully quick-release the pressure from the pot, sliding the steam release handle to the "Venting" position to release all of the steam until the float valve drops down.

Step 11

Carefully open the lid. Press the "Keep Warm/ Cancel" button.

Step 12

Transfer chicken skin-side up to a foil-lined sheet tray. Broil on high about 12-inches from the top of the oven to crisp the skin, about 3 to 5 minutes.

Step 13

Meanwhile, press "saute" on the "more" setting. Simmer and stir until sauce is reduced and thickened, 8 to 9 minutes. The sauce should be reduced to about ¾ cup.

Step 14
