Prepare your ingredients by dicing the onion, mincing the garlic, and measuring out the rice and mixed vegetables.
In the crockpot, place the chicken breasts at the bottom.
Sprinkle the diced onion, minced garlic, mixed vegetables, paprika, dried thyme, black pepper, and salt over the chicken.
Pour the chicken broth over all the ingredients, ensuring the chicken and rice are submerged.
Add the rice into the crockpot and stir gently to combine without disturbing the layer of chicken too much.
Cover the crockpot with the lid and cook on low for about 4 hours or until the chicken is cooked through and easily shreds with a fork.
Once done, shred the chicken using two forks and stir it back into the rice. Let it sit covered for a few minutes to allow the flavors to meld.
For an extra touch, drizzle with olive oil and garnish with fresh parsley before serving.
