Step 1

Place the trivet in the Instant Pot.

Step 2

Season the ribs generously with salt and pepper. Place them on top of the trivet in the Instant Pot and add the water.

Step 3

Close the lid and turn the valve to the sealing position. Select high pressure and set the timer for 30 minutes.

Step 4

When the cooking time is up, let the pressure release naturally for about 15 minutes. Quick release any remaining pressure.

Step 5

Remove the ribs from the pot and reserve the cooking liquid.

Step 6

In a small bowl, whisk together the barbecue sauce and ¼ cup of the reserved cooking liquid.

Step 7

Preheat the broiler or grill to high heat.

Step 8

Brush the ribs all over with the sauce mixture. If planning to broil them, arrange them, meat side up on a large, rimmed baking sheet that has been lined with foil.

Step 9

Place the ribs under the broiler or on the grill. Cook until the sauce bubbles and thickens, 5 to 6 minutes. Brush again with the remaining sauce mixture and cook for another 2 minutes or so.

Step 10

Serve hot with extra barbecue sauce, if desired.
