Turn on the Instant pot and turn on the saute function set to low for 10 minutes. Add the olive oil to the instant pot and allow the oil to heat for 1 minute.
Place the chicken in the instant pot for 3 minutes on each side or until each side is golden brown and has a nice sear. You may need to do this in batches until all the chicken has been seared. Remove the chicken from the instant pot and set to the side.
Add the minced garlic to the instant pot. Saute for 1 minute or until the garlic become fragrant. Using a wooden spoon scrape up any bits on the bottom of the pot. Add the chicken broth, Italian seasoning, salt, pepper, and crushed red pepper flakes, and heavy cream.
Drain the sun dried tomatoes and roughly chop them. Add the chopped sun dried tomatoes to the instant pot.
Using a fine mesh strainer rinse the rice and drain. Add to the instant pot. Add the seared chicken back to the pot.
Place the lid on the instant pot and place in the locking position. Set the sealing position. Set the instant pot to pressure cook, high heat, for 19 minutes.
Once it has finished cooking move the switch from the sealing position to vent. Allow to vent until the pressure indicator has fallen. Open the instant pot and add in the parmesan cheese and stir until the cheese is fully incorporated.
Let stand for 5 minutes before serving. As it cools it will begin to thicken.
