01 - Pat chicken thighs dry with paper towels. Rub evenly with salt, black pepper, smoked paprika, dried thyme, and oregano, coating all surfaces.
02 - Heat olive oil in a large skillet over medium-high heat. Sear seasoned chicken for 2-3 minutes per side until golden brown develops. Transfer to plate.
03 - Layer carrots, celery, onions, garlic, and baby potatoes in the bottom of the slow cooker insert, distributing evenly.
04 - Place seared chicken pieces on top of the vegetable bed, ensuring meat sits above the liquid line.
