Pat the chicken breasts dry with paper towels to ensure a good sear.
Season generously with salt, pepper, and smoked paprika on both sides, then let sit for 10 minutes to absorb the flavors.
Heat a heavy skillet over medium-high heat until it’s hot and shimmering, which takes about 2 minutes.
Add olive oil to the hot skillet, swirling to coat the bottom evenly, and wait until it just starts to shimmer and smoke slightly.
Place the chicken breasts in the skillet, skin-side down (if skin-on), and sear for 4-5 minutes until golden brown and crispy, listening for a gentle sizzle.
Flip the chicken breasts carefully using tongs, and add butter, minced garlic, and chopped herbs to the pan.
Baste the chicken with the melted butter, garlic, and herbs, tilting the pan slightly to spoon the flavorful pan juices over the top.
Reduce heat to medium and continue cooking for about 8 minutes, basting occasionally, until the internal temperature reaches 74°C (165°F).
Once cooked, transfer the chicken to a plate and let rest for 5 minutes; this helps retain the juices.
Squeeze fresh lemon juice over the rested chicken to brighten the flavors, then slice against the grain for serving.
Serve the sliced chicken with pan juices drizzled over the top for added moisture and flavor.
