Preheat your oven to 350 F ( 180 C).
In a large bowl, mix together the olive oil, paprika, onion powder, garlic powder, Italian seasoning, salt and pepper. Add the chicken and toss to coat. Allow to marinate for 30 minutes or overnight.
Spray a 10 x 15-inch | 25 x 35 cm baking dish with nonstick cooking oil spray. Add the onion, garlic, oil, salt, pepper and VERY HOT broth, hot water and butter into the baking dish. Mix to combine. Stir in the rice.
Place the chicken over the rice, cover with aluminium foil and bake for 30 minutes. Then uncover, spray chicken with oil ( for a nicer finish) and bake uncovered for 20-30 minutes or until the chicken is cooked through and liquid is absorbed. Broil further for 3-4 minutes to brown the chicken.
Remove the chicken, mix the rice and then return the chicken back. Cover with foil and allow to rest for 10 minutes.
Meanwhile, cook the mushrooms. Heat butter in a pan over medium-high heat. Add the garlic and thyme sprigs, and cook until fragrant, about 30 seconds.
Add the mushrooms and cook until softened.
Add the green onions and cook for 1 minute. Season with salt and pepper.
Transfer the chicken onto a plate, fluff rice with a fork, then mix with the mushrooms. Top with chicken again, garnish with green onions and thyme.
Serve and enjoy!
