Season the chicken thighs on both sides with salt, black pepper, and paprika.
Heat olive oil in a large skillet over medium-high heat. Sear chicken for 5 to 6 minutes per side until golden brown and cooked through. Remove chicken from the pan and set aside.
In the same skillet, melt the butter. Add the sliced onions and sauté for 5 to 7 minutes until softened and lightly caramelized.
Add the minced garlic and dried thyme, cooking for 1 minute until fragrant.
Pour in 1 cup of chicken broth and the heavy cream. Bring to a gentle simmer while scraping the bottom of the pan to incorporate the browned bits.
Return the chicken to the skillet, reduce heat to low, and simmer for 10 minutes until the sauce thickens.
Meanwhile, combine the rice and the remaining 1 cup of chicken broth (plus 1 cup water) in a medium saucepan. Bring to a boil, then cover and simmer on low for 15 minutes or until liquid is absorbed.
Fluff the rice with a fork and plate it. Top with a chicken thigh and a generous amount of the creamy onion gravy.
Garnish with fresh chopped parsley before serving.
