Start by preheating the oven to 375°F (190°C) to ensure proper cooking.
Lay the chicken breasts out evenly in a single layer in a big baking dish.
In a different pan, brown the chopped onion and minced garlic until they give off a pleasing scent.
Add the uncooked rice to the pan and stir for 2-3 minutes until the rice is evenly coated.
Add the chicken broth, diced carrots, frozen peas, thyme, basil, paprika, salt, and pepper to the pan.
Ensure the mixture is thoroughly combined, and then evenly spread it over the chicken in the dish.
Place the foil over the food and heat in the oven for a 25-minute duration.
Remove the foil and sprinkle grated Parmesan cheese over the top of the dish, if desired.
In order to completely bake the chicken and make the rice delicate, extend the oven time by an extra 10-15 minutes.
