Season the chicken thighs with a pinch of salt and pepper on both sides. This builds the base of flavor before they hit the pot.
Set the Instant Pot to the Sauté function and add olive oil. Once shimmering, brown the chicken on both sides for about 2-3 minutes per side. You’re not cooking it through at this stage—just building flavor and a bit of color.
Add minced garlic and ginger to the pot, and sauté for about 30 seconds until fragrant. This step is where the kitchen smells start to sing.
In a small bowl, whisk together honey, soy sauce, rice vinegar, and a pinch of red pepper flakes if using. Pour this honey-soy mixture over the browned chicken.
Pour in a little water (about 1/4 cup) to help deglaze the bottom, releasing those tasty browned bits. Scrape the pot with a wooden spoon to loosen any stuck-on bits.
Lock the Instant Pot lid in place, seal the vent, and set to high pressure for 6 minutes. Once the timer beeps, allow a natural release for 5 minutes, then perform a quick release to vent any remaining steam.
Open the lid and check the chicken for doneness. If you’d like a thicker glaze, whisk the cornstarch slurry in a small bowl and stir into the sauce. Simmer for 1-2 minutes until glossy and thickened.
If you’ve added a slurry, you’ll notice the sauce turning silky. Taste and adjust salt if needed. If you’re skipping the slurry, you can still finish with a splash of sesame oil for aroma.
Remove the chicken to a plate and spoon the glaze over the top. Return to the sauce pot if you want even more surface coverage. Garnish with green onions and sesame seeds for a bright finish.
Serve the honey garlic chicken over steamed rice, quinoa, or a bed of bok choy or broccoli. The sauce doubles nicely as a glaze for vegetables, so don’t waste any of the delicious bit.
