Season the chicken breasts with salt, pepper, garlic powder, and onion powder.
Heat olive oil in a large skillet over medium heat and brown the chicken on both sides. Remove and set aside.
In the same skillet, sauté the diced onion and minced garlic until soft and fragrant.
Add the rice and cook for 1-2 minutes, stirring occasionally.
Pour in the chicken broth and heavy cream, then stir in paprika, thyme, and oregano.
Return the chicken to the skillet, cover, and let simmer for 20-25 minutes until the rice is cooked and the chicken is tender.
Sprinkle shredded cheddar cheese over the dish, cover, and let it melt.
Garnish with chopped parsley and serve warm.
