In a large bowl, whisk together lemon juice, minced garlic, olive oil, thyme, honey, and paprika. Season generously with salt and pepper. Add the chicken thighs to the bowl and toss to coat evenly with the marinade. Let it sit for at least 30 minutes at room temperature, or for optimal flavor, cover and refrigerate for a few hours or overnight.
Preheat your oven to 400°F (200°C).
Arrange the chicken thighs skin-side up in a large baking dish. Make sure they are not overcrowded. Tuck the lemon slices among the chicken thighs.
Bake in the preheated oven for about 35-40 minutes, or until the chicken is cooked through and the skin is crispy. The internal temperature should reach 165°F (74°C). For extra crispy skin, broil the chicken on high for 2-3 minutes at the end of cooking. Watch carefully to prevent burning.
Remove the chicken from the oven and let it rest for a few minutes. Garnish with fresh parsley before serving.
