Season chicken thighs evenly on both sides with salt, pepper, and paprika.
Heat olive oil in a large heavy-bottomed skillet over medium-high heat until shimmering.
Place chicken in the skillet and sear for 6-7 minutes per side until golden brown and the internal temperature reaches 165°F (74°C).
Reduce heat to medium-low and add the butter and minced garlic to the skillet.
Tilt the pan slightly and use a large spoon to continuously baste the chicken with the foaming garlic butter for 2 minutes to create a juicy finish.
Remove the skillet from the heat, stir in lemon juice and parsley, and serve immediately.
