Wash and rinse the chicken, pat dry with paper towels and season with salt and pepper, set aside.: The first thing you will notice is how dry skin browns more uniformly, producing a deep mahogany color and a toasty aroma that signals caramelization. Patting the chicken thoroughly removes surface moisture so the skin can crisp rather than steam, and seasoning early lets the salt start penetrating the meat. If the skin is wet when it hits the pan you will get steam which prevents browning, so always dry well. A common problem is using too little salt which yields a bland result; be confident but not excessive. The sound cue here is a quick hiss when the chicken hits hot oil, which means you have proper surface temperature.
Turn the Instant Pot on the Saute mode. Once hot, add 2 tablespoons of oil, once the oil is shimmering, sear the chicken thighs and drumsticks in batches, starting skin side down, until nicely browned.: As you sear, watch for the skin to render and take on a rich golden brown, the aroma will shift from raw poultry to nutty and caramelized scents. Searing in batches prevents overcrowding, allowing each piece to make direct contact with the pan for even crust formation. If the oil is not shimmering you will get pale, soggy skin so wait until it glistens and moves in the pan. A frequent mistake is flipping too often, which interrupts Maillard reactions, so let each side develop color undisturbed. You'll hear a steady sizzling, and the browned bits left in the pot add flavor when deglazed later.
Remove chicken and set aside.: Moving the browned chicken out of the pot prevents it from overcooking while you build the sauce, and preserves those fond bits for deeper flavor. The pot will smell toasted and savory at this stage. Try not to wipe the pot clean, because those browned fragments will dissolve into the sauce and give it complexity. A mistake here is leaving the chicken in the pot too long, which can lead to overcooked texture once pressure is applied.
Add onion and tomato and cook until tomatoes start to break down about 3 minutes.: When the onion softens and the tomatoes begin to collapse, the mixture will smell sweet and slightly acidic, and the pan will release more fond. This quick cook mellows onion sharpness and coaxes juices from the tomatoes which help form the base of the sauce. If you see burning, lower the heat and add a splash of broth, since scorched aromatics will impart bitterness. Stir occasionally but let the vegetables make contact with the pot to develop flavor.
Combine the sauce ingredients in a small bowl and stir until the honey is completely dissolved. Set aside.: Mixing the balsamic vinegar , honey , molasses , spices, and other sauce components until smooth produces a homogenous glaze that will coat the chicken evenly. The aroma brightens as the vinegar hits the sweeteners and spices, and dissolving the honey prevents clumps that could caramelize unevenly. If honey or molasses remains unmixed you may get pockets of intense sweetness in the final dish, so whisk until glossy. Keep the mixture at room temperature to aid incorporation.
Pour in the chicken broth, then the sauce in the Instant Pot, and give it a quick stir.: Adding the chicken broth first loosens the browned bits and deglazes the pot, creating a savory base that tempers the acidity of the vinegar. When the sauce is added, it blends with the broth and aromatics, and you will see a darker, glossy liquid form. Stirring briefly helps distribute spices and prevents hot spots, but do not over stir as that can break down the onions and tomatoes prematurely. Watch for a gentle steam rising, and if the mixture looks too thin the flavors will still concentrate during pressure cooking.
Add a trivet to the IP. Add the chicken back to the IP on the trivet.: Using a trivet lifts the chicken out of the liquid so it cooks in steam while still being kissed by the sauce when served, preserving the seared crust and avoiding mushy skin. Placing the pieces evenly allows pressure to circulate properly and ensures uniform doneness. A common oversight is stacking pieces too tightly, which inhibits even cooking, so arrange them with small gaps. You may notice the sauce bubbling softly around the base when the pot comes to pressure.
Cover the lid. Select Manual or Pressure Cook mode and set to High pressure for 10 minutes.: Under high pressure the connective tissues in the chicken break down quickly, yielding tender meat that shreds easily and soaks up sauce. The Instant Pot will build pressure, and you will hear the machine begin its steady hum; that is normal. Setting the precise time ensures consistent results, and the high setting is what turns the sauce rich without overcooking the meat. Avoid opening the lid while pressurizing, as that interrupts the cycle and lengthens cook time.
Once done, do a quick pressure release.: The quick release stops the cooking immediately, preserving the texture of the chicken and keeping the sauce bright. You will hear a rush of steam when you vent, and the pot will cool enough to open. If you wait too long to release, the meat can continue to steam and become overly soft. Use tongs and keep your hands clear of the vent to avoid burns during this step.
Sprinkle with the parsley and serve the honey balsamic chicken with the sauce on top of rice or pasta.: The final scent is a concentrated mix of sweet, tangy, and warm spices, and the glossy sauce clings to the chicken creating a pleasing sheen. Garnishing with chopped parsley refreshes the plate with herbal color, and serving over grains catches every drop of sauce. A common serving mistake is discarding the pan sauce; instead spoon it over the meat and sides to maximize flavor. Enjoy the contrast of tender meat and silky sauce in each bite.
