In a large bowl, combine the salt, black pepper, garlic powder, onion powder, thyme, and rosemary. Rub the spice mixture all over the chicken thighs, ensuring they are well coated.
Heat the olive oil in a large skillet over medium-high heat. Add the seasoned chicken thighs and sear for about 4-5 minutes on each side until golden brown. Remove from heat.
In the bottom of the crockpot, layer the chopped carrots, diced potatoes, and quartered onion.
Place the seared chicken thighs on top of the vegetables in the crockpot.
Pour the chicken broth over the chicken and vegetables, ensuring everything is submerged.
Cover and cook on low for 6-8 hours or on high for 4-5 hours, until the chicken is tender and fully cooked.
Once done, carefully remove the chicken and vegetables from the crockpot. Serve hot, garnished with fresh parsley.
Notes
For a richer flavor, add a splash of white wine to the broth before cooking.
You can substitute the chicken thighs with boneless, skinless chicken breasts for a leaner option.
