Preheat your oven to 375°F (190°C) and lightly grease a 9x13-inch casserole dish.
Season the chicken breasts with salt, pepper, thyme, rosemary, and garlic powder.
Heat a large skillet over medium heat and add the olive oil. Sear the chicken breasts for 4-5 minutes on each side until golden brown. Remove and set aside to cool slightly before cutting into bite-sized pieces.
In the same skillet, melt the butter. Add the diced onion and sauté until softened, about 3-4 minutes. Add the minced garlic and sauté for another 30 seconds until fragrant.
Sprinkle the flour over the onions and stir to form a roux. Cook for 1 minute, then slowly whisk in the chicken broth and heavy cream. Bring to a simmer and cook until the sauce thickens, about 3-4 minutes.
Stir the frozen mixed vegetables into the sauce, followed by the shredded cheddar cheese. Mix until the cheese melts and the sauce is creamy. Remove from heat.
In a large mixing bowl, combine the cooked rice, bite-sized chicken pieces, and the creamy vegetable sauce. Mix until evenly distributed.
Transfer the mixture into the prepared casserole dish, spreading it evenly.
Sprinkle the breadcrumbs over the top of the casserole for a crunchy topping.
Bake in the preheated oven for 25-30 minutes, or until the casserole is bubbly and the breadcrumbs are golden brown.
Remove from the oven and let sit for 5 minutes. Garnish with fresh parsley before serving.
