Season the Chicken: In a bowl, mix garlic powder, paprika, onion powder, salt, and Italian seasoning. Rub this seasoning all over the chicken thighs.
Sear for Extra Flavor (Optional): Heat olive oil in a skillet over medium-high heat. Sear chicken thighs for 2-3 minutes per side until golden brown.
Prepare the Crockpot: Pour the chicken broth into the slow cooker and place the seared chicken thighs inside.
Add the Flavor Boost: Scatter minced garlic and diced butter over the chicken for rich, buttery goodness.
Slow Cook to Perfection: Cover and cook on low for 4-6 hours or high for 2-3 hours until the chicken is tender and fully cooked.
Garnish & Serve: Sprinkle fresh parsley on top and serve hot with your favorite side dish!
