Prepare the Crockpot: Lightly grease the inside of your Crockpot with cooking spray or a small amount of oil.
Layer Chicken: Place the chicken breasts at the bottom of the Crockpot. Season with salt, pepper, paprika, onion powder, and dried thyme.
Add Rice and Vegetables: Spread the uncooked rice over the chicken. Add the diced onion, garlic, carrots (if using), and frozen peas.
Add Broth: Pour the chicken broth over the rice and chicken, ensuring the rice is fully submerged in the liquid.
Cook: Cover the Crockpot and cook on low for 4-6 hours, or until the chicken is fully cooked and the rice is tender.
Shred Chicken: Once cooked, remove the chicken breasts and shred them with two forks. Return the shredded chicken to the Crockpot and stir to combine.
Taste and Adjust: Taste the mixture and adjust seasoning with additional salt, pepper, or spices as needed.
Serve: Scoop the chicken and rice into bowls, garnish with fresh parsley, and serve hot. Enjoy!
