Season the chicken thighs with salt, pepper, and paprika.
Heat a skillet over medium heat and sear the chicken thighs until golden brown on both sides.
Remove the chicken and place it in the crockpot.
In the same skillet, sauté the diced onion and minced garlic until fragrant.
Add the sautéed onion and garlic to the crockpot over the chicken.
Pour in the chicken broth and add the rice.
Sprinkle dried thyme and mix gently to combine.
Cover the crockpot and cook on low for 6-8 hours or high for 3-4 hours.
About 30 minutes before serving, add the frozen peas to the crockpot.
Garnish with fresh parsley before serving.
