Step 1

Arrange a rack in the middle of the oven and heat the oven to 425°F. Lightly coat a baking dish large enough to fit the chicken in a single layer with some room around each one with butter.

Step 2

Melt 3 tablespoons unsalted butter in a small saucepan over medium-low heat or in a small bowl in the microwave. Add 1 tablespoon salt-free Lemon Pepper seasoning and 1 teaspoon kosher salt and stir until combined.

Step 3

Pat 4 boneless, skinless chicken breasts dry with paper towels. Place the chicken in the prepared baking dish, spaced slightly apart. Brush the chicken all over with all of the butter mixture.

Step 4

Thinly slice 1 lemon and scatter the slices around the chicken. Bake until the chicken is golden-brown, cooked through, and registers 165°F on an instant-read thermometer, 25 to 35 minutes. Meanwhile, coarsely chop enough parsley leaves to get 2 tablespoons. Serve the chicken garnished with the parsley.
