Drizzle 1 Tablespoon of olive oil all over the turkey breast and rub it in.
In a small bowl, combine the spices.
Rub the spice mixture all over the outside of the turkey breast.
Add the trivet (wire rack that came with your Instant Pot) into the bottom of the pot. Pour 1/2 cup of water into the pot. Place the turkey on top of the trivet.
Close the lid and push MANUAL (or PRESSURE COOK) and set the timer to 25 minutes.
Once the Instant Pot cycle is complete, let the pot do a natural release cycle (should take about 10 to 15 minutes - you will hear the pin drop when the pressure has naturally released).
Carefully unlock and remove the lid from the Instant Pot.
Transfer the turkey breast to a cutting board, cover completely with aluminum foil and let it rest for 10 to 15 minutes before cutting into it.
If crispier skin is desired, broil it in the oven for an additional 5-10 minutes.
Cut turkey into slices and serve.
Notes
The general rule of thumb for cooking poultry in the Instant Pot is 6 minutes per pound with a 10 minute NPR (Natural Pressure Release).
4 lb Turkey or Turkey Breast = 24 minutes + 10 minutes NPR
8 lb Turkey or Turkey Breast = 48 minutes + 10 minutes NPR
