1.5 cups long-grain white rice β uncooked, rinsed
fresh parsley β chopped (for serving)
Instructions
Preheat the oven to 375Β°F. Lightly oil a 9x13-inch baking dish.
Season the chicken thighs all over with the sweet paprika. Heat the neutral oil in a large skillet over medium-high heat. Sear the chicken skin-side down until well browned, 6β8 minutes; flip and sear 1β2 minutes on the second side. Transfer to a plate.
Reduce the heat to medium. Add the unsalted butter to the skillet. When melted, add the finely chopped onion and celery and cook, stirring, until softened and lightly golden, 5β7 minutes. Stir in the minced garlic and crumbled dried thyme and cook until fragrant, 30β60 seconds.
Sprinkle in the all-purpose flour and cook, stirring constantly, 1β2 minutes to form a blond roux. Gradually whisk in the chicken broth and then the whole milk, whisking until smooth. Simmer, whisking, until the sauce thickens to a light cream-sauce consistency, 3β5 minutes. Season the sauce with the kosher salt and freshly ground black pepper.
Spread the rinsed long-grain white rice evenly in the prepared baking dish. Pour the hot sauce over the rice and stir to distribute so all grains are submerged.
Nestle the browned chicken thighs skin-side up on top of the rice and sauce. Cover the dish tightly with foil.
Bake covered for 45 minutes. Uncover and continue baking 20β30 minutes, until the rice is tender and most liquid is absorbed around the edges and the chicken registers 175Β°F in the thickest part.
Rest the casserole 10 minutes. Fluff the rice around the chicken, sprinkle with chopped fresh parsley, and serve hot.
