Set your IP to saute and add vegetable oil. In batches, brown all the chicken pieces and remove to a bowl.: The moment the pot goes into sauté mode you should hear a steady sizzle as the vegetable oil warms, and the smell of browning will begin to build. Browning in batches prevents crowding, so pieces sear instead of steaming, creating a rich caramelized layer on the chicken skin that deepens the final stock flavor. As you pull browned pieces to a bowl, notice the fond stuck to the bottom, those browned bits are flavor gold. A common mistake is using too high heat which can scorch the fond and create bitterness; moderate heat is key. If chicken sticks excessively, deglaze with a splash of water and scrape gently to lift flavorful bits before proceeding.
When all the chicken is browned, return the chicken to the Instant Pot along with all the other ingredients.: Once the chicken is back in the pot with the chopped onion , carrots , celery , smashed garlic , fresh herbs, peppercorns , salt , and the water , you will see the colors meld as steam starts to rise. The mixture will suddenly smell more layered, a mix of roasted meat and bright vegetables. Adding everything together ensures even extraction. Avoid overfilling beyond the Instant Pot's max line, or the cooker may not seal properly and pressure may not build.
Select high pressure and set the timer to 60 minutes. When the timer goes off, turn off the IP and either let vent naturally or use the quick release (there will be a lot of steam!).: As the cooker comes to pressure you will hear a low hum and occasional clicks, and the aroma will become richer and rounder. High pressure accelerates collagen and gelatin extraction from bones, producing a silky mouthfeel in far less time than stovetop simmering. Resist the urge to open the lid during pressure build up which can interrupt the process and lengthen cooking time. If the IP struggles to reach pressure, check the sealing ring is properly seated and that the vent is closed.
When the pressure is released, remove the lid. Remove the chicken pieces to a clean bowl.: Natural release yields a gentler finish and can keep the stock clearer, while quick release ejects steam quickly and speeds the process. Either way you will notice a burst of savory steam and a deepened, concentrated aroma when the lid comes off. Be cautious of the hot steam, and use an oven mitt or long utensil to flip the valve for quick release. A common error is placing your face too close to the vent during release, which risks burns from the intense steam.
Let the stock cool a bit before pouring through a fine-mesh strainer to remove the vegetables, herbs, and impurities.: After removing the lid you will be greeted by a robust, layered scent. Transferring the chicken to a bowl allows you to cool and shred the meat separately, while the bones remain in the stock to provide body. Touch the meat once it is cool enough, it should pull apart easily; if it is still firm the meat may need a bit more rest. If bones are left too long they can break down and create small fragments in the stock, so strain carefully.
Cover the bowl and let cool in the refrigerator. When cool, scrape off any accumulated fat on the surface and divide it into storage containers.: As the stock cools slightly you will see fat rise to the surface and solids sink, making straining cleaner and easier. Pushing the liquid through a fine mesh removes small particulates and results in a clear, polished stock. Expect a warm, golden liquid with a glossy surface and a rounded aroma. A common pitfall is pressing solids too hard through the strainer, which can cloud the stock; let gravity do most of the work.
When the chicken is cool enough to handle, shred the meat and place it in storage containers to use in future recipes.: Chilling will firm up the fat so it lifts away cleanly, leaving a clear, rich stock beneath. Removing excess fat yields a lighter mouthfeel and extends shelf life. Spoon off the congealed fat for other uses or discard it. If you skip chilling, the fat remains dispersed and makes the stock greasier, which may be undesirable depending on your intended use.
When the chicken is cool enough to handle, shred the meat and place it in storage containers to use in future recipes.: The cooked chicken will be tender and fragrant, perfect for repurposing in soups, salads, or sandwiches. Shredding while slightly warm is easier and helps the meat remain moist. Store the meat separately from the stock to allow you to use each component as needed. One mistake is storing everything together without cooling properly, which can lead to faster spoilage; always cool safely before refrigerating.
