Start by seasoning the flour with salt and black pepper in a shallow dish. Dredge each chicken thigh in the flour mixture, coating well.
In a large skillet, heat the olive oil over medium heat. Add the coated chicken thighs and cook for about 5-7 minutes on each side until golden brown. Remove the chicken from the skillet and set aside on a plate.
In the same skillet, add the chopped onion, garlic, and bell pepper. Sauté for about 4 minutes until vegetables are softened.
Stir in the chicken broth, dried thyme, and paprika. Bring to a gentle simmer.
Add the browned chicken thighs back into the skillet, cover, and let them simmer for about 25 minutes until the chicken is cooked through and tender.
While the chicken is cooking, prepare the rice according to package instructions in a rice cooker or saucepan.
Once everything is cooked, serve the smothered chicken over a bed of rice. Spoon the gravy over the top and garnish with green onions if desired.
