Start by preparing the marinade the day before cooking. Thinly slice the onion and mince the garlic. In a large bowl, combine the cream of mushroom soup, sour cream, chicken stock, white wine (if using), salt, black pepper, paprika, and dried thyme. Mix well.
Place the chicken breasts in the marinade, ensuring they are fully coated. Cover the bowl with plastic wrap and refrigerate for 24 hours to allow the chicken to absorb the flavors.
The next day, preheat your oven to 350°F (175°C). Grease a 9x13-inch casserole dish with butter.
Pour the uncooked rice into the bottom of the casserole dish and spread it evenly. Add the frozen peas on top of the rice.
Remove the chicken breasts from the marinade and place them on top of the rice and peas. Pour the remaining marinade over the top.
Cover the casserole dish tightly with aluminum foil and bake for 1 hour.
After 1 hour, remove the foil and sprinkle the shredded cheddar cheese evenly across the top of the casserole.
Return the casserole to the oven and bake uncovered for an additional 30 minutes, or until the cheese is melted and bubbly and the chicken is fully cooked (internal temperature should reach 165°F or 74°C).
Remove the casserole from the oven and let it rest for 5 minutes before serving. Garnish with chopped parsley, if desired.
Serve hot and enjoy!
