Preheat your oven to 425°F (218°C). This high temperature ensures the chicken will cook evenly and retain its juices.
Season the chicken breasts evenly with ½ teaspoon of salt. This is the first layer of flavor to enhance the final dish.
Heat the olive oil in a large ovenproof skillet over medium-high heat. Once the oil shimmers, it’s ready.
Add the chicken to the skillet and cook undisturbed for about 4 minutes, or until the underside is golden brown.
Flip the chicken breasts and arrange the thinly sliced lemon around them in the pan. The lemon slices will infuse the chicken with extra citrus brightness as it cooks.
Transfer the entire skillet to your preheated oven. Bake for about 10 minutes, or until an instant-read thermometer inserted into the thickest part of the chicken reads 165°F (74°C).
Remove the skillet from the oven and transfer the chicken to a serving platter. Let it rest to lock in the juices.
Return the skillet to the stovetop over medium heat. Add the lemon juice and maple syrup, scraping up any browned bits for added flavor. These bits contain rich umami goodness.
Stir in the butter, one piece at a time, until it fully melts and the sauce becomes silky. Sprinkle in the cracked pepper and remaining 1/8 teaspoon of salt.
Drizzle the warm, buttery lemon sauce over the plated chicken. Serve immediately and enjoy!
