In a bowl, mix together the olive oil, minced garlic, chicken broth, lemon juice, oregano, thyme, paprika, salt, and pepper until well combined.
Place the chicken thighs in the slow cooker and pour the lemon garlic mixture over them, ensuring the chicken is evenly coated.
Cover the slow cooker and cook on low for 6 to 7 hours or on high for 3 to 4 hours, until the chicken is tender and easily shreds with a fork.
Once cooked, remove the chicken from the slow cooker and set it aside. If desired, you can thicken the sauce by turning the slow cooker to high and letting it simmer uncovered for about 15 minutes.
Serve the chicken garnished with fresh parsley, alongside your choice of sides.
