• Put the water in the inner liner of the Instant Pot, and put the wire rack/trivet in also.
• Rub the turkey breast with the olive oil and rub the spices all over it.
• Place the turkey breast in the pressure cooker, however it fits best (I try to put mine breast meat side down, but have cooked some on their sides). Also add in the onion and garlic, if using.
• Put the lid on the IP and set the steam release knob to the Sealing position.
• Press the Pressure Cook, or Manual button, and then the + or - button to choose the time in minutes (I have had the good results with about 25 minutes for a smaller 2-4 pound breast, and about 30 minutes for a 5-6 pound breast about 40 minutes for a 7 lb breast). High pressure.
• When the cooking cycle has ended, let the pot sit and naturally release for 15 minutes. Then manually release the remaining steam. When the pin in the lid drops, open the pot.
• Take the temperature and determine if it is fully cooked. If it is below 165 degrees F, put the lid back on the pot and set the IP to cook for a couple more minutes and let it naturally release for 10 minutes. 

  I always take the temperature with an instant read thermometer. You want it to be 165 degrees F to be fully cooked.
  
• Remove the turkey breast to a baking pan. Also remove the wire rack/trivet.
  

Cook the Potatoes

• Put the whole potatoes in the pot, close the lid and set the steam release knob to the Sealing position.
• Press the Manual, or Pressure Cook button, and then the + or - button to choose 10 minutes. When cooking cycle is done, do a Quick Release of the pressure (Carefully turn the steam release knob immediately after the pot beeps to release the pressure)
• Remove potatoes and set aside while you make the gravy.

Brown the Turkey While the Potatoes are Cooking (optional step)

• Set your oven rack to the lowest position. Turn on your broiler to 425 degrees F to begin warming up.
• Place the baking pan with the turkey breast, skin side up, under the broiler. Let it brown a few minutes (depending on the size of the turkey breast, you might need to turn it to get all of it browned). If you don't want to brown it, just skip this step and let it rest, covered, while the potatoes cook.

Make the Gravy

• Press the Sauté button (Normal heat) on the pressure cooker.
• In a microwave safe dish, mix the butter and flour and microwave for about 20-25 seconds.
• When the drippings in the pot start to simmer, stir in the butter/flour mixture. Keep stirring until the gravy thickens.
• Serve!
