I start by mixing the smoked paprika, mixed herbs, garlic powder, onion powder, salt, and pepper in a small bowl. I rub most of this blend over the chicken thighs, saving about a teaspoon for later. This little reserve makes sure the rice gets seasoned too, not just the chicken.
While the chicken sits with its seasoning, I rinse the basmati rice under cold water until it runs clear. This step washes away the extra starch that would otherwise make the rice gummy. I set the rinsed rice aside so it's ready to go straight into the pan later.
I heat the olive oil in my skillet over medium-high heat, then add the chicken thighs and sear them for about three minutes per side until golden. I don't worry about cooking them through at this point, since they'll finish cooking with the rice. Once seared, I move the chicken to a plate and set it aside.
In the same pan, I sauté the chopped onion until it turns soft and translucent, then stir in the butter until it melts. Next, I add the rinsed rice and toast it for a minute or two, stirring so it doesn't stick to the bottom. This quick toasting step gives the rice a slightly nutty flavor before any liquid goes in.
I pour the chicken stock over the rice along with my reserved seasoning, then stir well and scrape up any browned bits stuck to the pan. I nestle the seared chicken thighs back on top of the rice, cover the pan, and let everything simmer on low-medium heat for fifteen to twenty minutes. I know it's ready once the rice is tender and the liquid has fully absorbed.
Once the rice is cooked, I sprinkle chopped green onions over the top, cover the pan again, and let it rest for about three minutes. This little rest helps the flavors settle before I fluff the rice with a fork. From there, it's ready to serve straight from the pan.
