Pound & Season Chicken: Begin by patting dry the chicken breasts with kitchen tissue and than pound them gently. This will prevent them from curling up when seared. Now, season the chicken breasts both sides with paprika, crushed black pepper & salt and rub them well.
Dredge chicken breasts: Now, dredge the seasoned chicken breasts nicely with all-purpose flour both sides. Shake off excess flour and set them aside on a clean dry plate.
Sear dredged chicken: Set the Instant Pot on SAUTE function & set it on HIGH heat. Add butter & oil. When it becomes hot gently add the chicken breasts and sear both sides until golden. Set them aside.
De-glaze pot: Now, add the capers in the same pot and saute them for just 30 seconds, crush a few capers with the back of your ladle. This will help them release a lot of flavor. Pour the white wine, chicken stock and de-glaze the pot very well scraping the sides & the bottom of the pot with the help of your spatula. This will help loosen any stuck food particles & prevent the BURN error! Also, add the garlic powder & lemon zest, little salt and stir to mix well. CANCEL the SAUTE.
Pressure Cook: Now, transfer back the seared chicken breasts into the pot and layer them in a single layer. DO NOT stir or mix. Secure the lid, seal the valve & pressure cook on HIGH for 4 mins. Once, the cooking cycle is over allow the pressure to release naturally for 5 mins and than release the rest of the pressure manually by moving the valve from the SEALING to the VENTING position. Open the lid carefully!
Prepare Piccata Sauce: Next, fish out the cooked chicken breasts with the help of a tong and set them aside. Hit back the SAUTE function & set it on NORMAL heat. Throw in the diced fridge cold butter (important) and stir until the butter is fully incorporated into the sauce. Simmer the buttery piccata sauce for 1 minute. TURN OFF the instant pot and add the lemon juice. Mix well. Piccata sauce is ready!
Serve Chicken Piccata: Now, transfer back the cooked chicken breasts into the pot. Coat them with the Piccata sauce. Allow them to rest for 5 mins and than serve them hot with the piccata sauce poured on top. Enjoy! Tastes best when served immediately from pot to plate!
