In a large bowl add chicken, potatoes, olive oil, salt and pepper, toss well.: The aroma of olive oil blending with freshly cracked pepper and salt will hit you first, and you should feel the coarse texture of the seasonings coating the surfaces as you toss. This contact seasons both the exterior of the chicken and the skin of the baby potatoes , helping them brown and develop flavor during saute. When you toss, listen for the quiet clink of potatoes against the bowl, and look for an even sheen of oil on every piece. If you skip this even coating, you risk patchy browning and less flavor penetration.
Add the rest of the seasonings and toss well to combine.: As you sprinkle in the garlic powder, onion powder, smoked paprika, and dried herbs, inhale the layered scent that emerges, which hints at the final complexity. Tossing ensures each item picks up tiny granules of seasoning so no bite is bland. A common mistake here is rushing and not distributing seasonings evenly, which creates spots that taste under seasoned while others are too strong.
Click on saute on the IP, add more olive oil, and tilt the pot to distribute it evenly.: When the IP clicks to the saute setting, you should notice a faint shimmering on the oil when it is hot, signaling readiness to brown. Tilting the pot ensures a thin, even layer of oil coats the surface so the chicken makes good contact. If the oil smokes immediately, the heat is too high, so lower it to prevent burnt flavor.
Once the oil is hot, brown the chicken breasts on all sides. Set aside.: Browning creates a fragrant crust, a sound like a brief sizzle that tells you Maillard reactions are happening, which add deep, savory flavor. Turn the pieces when they release easily and show golden edges. Set them aside on a plate to rest briefly, letting carryover heat continue to develop flavor. Overcrowding during this stage prevents proper browning and causes steaming instead of searing.
Add the chicken broth and scrape the bottom well of any bits that stuck to it.: Pouring in the chicken broth releases those stuck brown bits, or fond, without heat you can see them dissolve and the broth turn a richer color. Scraping with a wooden spoon lifts flavor into the liquid, which will then coat the other ingredients. Missing this step leaves flavor behind and can increase the chance of a burn notice on the pressure cooker.
Next add the potatoes and top with the chicken.: Layering the baby potatoes first lets them sit in the broth so they absorb liquid and seasonings, while placing the chicken on top helps steam circulate. You will notice the potatoes settle and the arrangement looks snug and ready for pressure. If you pile everything awkwardly, steam circulation may be uneven and cause inconsistent cooking.
Lock the lid and turn the vent to the sealed position.: When you lock the lid and set the valve, you should feel a satisfying click, and the pot will begin building pressure. This seal traps steam, converting liquid to high pressure which cooks efficiently. Forgetting to set the vent to sealed prevents pressure buildup and leads to undercooked results.
Pressure cook on HIGH for 10-15 minutes, if the potatoes and chicken are too thick pressure cook for 15 minutes.: Inside the sealed environment, the sound will drop to a quiet hum, and the timing converts the texture of both ingredients to tender and cohesive. The shorter end yields just tender potatoes and juicy chicken , while the longer time ensures larger pieces are fully cooked through. A common error is misjudging thickness; always check the largest piece for doneness to avoid rubbery meat or hard potato centers.
Once the cooking time is finished, do a 'Quick Pressure Release'.: Releasing pressure quickly produces a light hiss as steam escapes, and you will smell the concentrated aromas suddenly bloom. This method stops cooking immediately, preserving texture and preventing overcooking of delicate chicken. Be careful during release, because steam is hot and can burn; use a tool to flip the valve if needed.
Open the lid and use a slotted spoon to transfer the chicken and potatoes to a large serving platter.: When you lift the lid, a wave of steam carries a rich, savory scent. Use a slotted spoon to drain excess broth and keep the pieces intact, arranging them attractively. If you try to lift everything at once, the pieces may break apart, so gentle transfers maintain presentation.
Sprinkle with more Ranch seasoning, parmesan cheese, and garnish with chopped fresh parsley and serve.: As you finish with the dry Ranch and grated parmesan cheese , their salt and umami sing against the warm surfaces, and the cheese may melt slightly into pockets on the potatoes. A final sprinkle of chopped parsley, if you have it, adds green color and a fresh top note. Overdoing the finishing salt or cheese can overshadow the balanced flavors developed during cooking, so taste before adding more.
