Before you begin, spray the inside of your slow cooker with non-stick cooking spray. This helps prevent sticking and makes cleanup easier. You can also lightly brush it with olive oil if you prefer.
Place the chicken breasts or thighs at the bottom of the slow cooker. Try to spread them evenly so that they cook uniformly. If you're using large chicken breasts, you can cut them in half to ensure quicker, even cooking.
In a large mixing bowl, combine the cream of chicken soup, chicken broth, sour cream, garlic powder, onion powder, paprika, salt, and pepper. Whisk everything together until it’s smooth and creamy. This mixture forms the base flavor of your dish.
Now stir in the uncooked long grain white rice along with any optional vegetables like peas or carrots. Make sure everything is well-coated. Pour this entire mixture over the chicken, spreading it evenly and ensuring the rice is fully submerged in the liquid.
Cover your slow cooker and cook on low for 4–6 hours or on high for 2–3 hours. Don’t open the lid during cooking—this traps heat and ensures the rice cooks evenly. It’s done when the chicken is tender and the rice has absorbed all the creamy goodness.
Carefully remove the chicken from the slow cooker and shred it using two forks. Return the shredded chicken back into the slow cooker and give everything a good mix.
Now comes the fun part—cheese! Sprinkle in your shredded cheddar and stir until the cheese melts and turns everything creamy and rich. You’ll love the texture and flavor it brings.
Top your casserole with chopped parsley for a fresh and colorful finish. Serve it warm with a side of greens or steamed veggies.
