In a small bowl, mix the garlic salt, paprika, and pepper together. Sprinkle half of the seasoning mixture on the chicken thighs. In a medium skillet over medium high heat add in 1 tablespoon oil and then place the chicken thighs skin down and sear for 2 minutes or until golden. Combine the remaining seasoning mix with the minced garlic and remaining 2 tablespoons oil. Halve or quarter your baby potatoes depending on size. Toss the potatoes with the seasoning mix and place in the bottom of your slow cooker. Add the chicken on top of the potatoes. Cook on LOW heat for 6-7 hours or HIGH for 3-4 hours. Right before serving sprinkle with the parmesan cheese. Top with parsley for a pop of color if you like.
