Preheat your oven to 300°F (150°C).
In a large Dutch oven, heat a drizzle of oil over medium heat. Add the chopped onion and minced garlic, sautéing until translucent (about 3-4 minutes).
Remove the onion and garlic from the pot and set them aside. In the same pot, add the chicken thighs, skin side down, and sear them for about 5 minutes until golden brown. Flip and brown the other side for another 5 minutes.
Once the chicken is browned, remove it from the pot and set it aside.
Add the rice to the pot and stir for a minute to toast it slightly.
Mix in the cream of mushroom soup, chicken broth, sautéed onions, and garlic. Stir well to combine, making sure no rice is stuck to the bottom.
Season the mixture with paprika, thyme, black pepper, and salt.
Place the chicken thighs skin side up on top of the rice mixture, cover the pot with its lid, and transfer it to the preheated oven.
Bake for 2 hours without removing the lid.
After cooking, remove the pot from the oven, let it rest for a few minutes, and then serve hot, garnished with fresh parsley if desired.
