Preheat the oven to 425°F (220°C). Line a baking sheet with foil or parchment for easy cleanup, or use a lightly oiled baking dish.
Optional quick brine: If you have 15–30 minutes, stir 2 tablespoons salt into 4 cups cold water.
Submerge the chicken breasts, then drain and pat very dry. This helps keep the meat juicy.
Even out thickness: If the breasts are very thick on one end, place them between two sheets of plastic or parchment. Gently pound the thicker side with a rolling pin or mallet until each piece is about the same thickness, around 3/4 inch.
This ensures even cooking.
Mix the garlic herb paste: In a small bowl, combine olive oil, minced garlic, kosher salt, pepper, dried Italian seasoning, smoked paprika, lemon juice, and lemon zest. Stir into a loose paste.
Coat the chicken: Pat the chicken very dry. Rub the garlic herb paste all over, coating both sides.
Place the breasts on the prepared sheet, with a little space between each piece.
Bake: Roast for 16–22 minutes, depending on thickness. Start checking at 16 minutes. The chicken is done when the internal temperature reaches 165°F (74°C) at the thickest point.
Rest: Remove from the oven and let the chicken rest for 5–10 minutes.
Resting keeps juices in the meat, not on your cutting board.
Finish and serve: If you like, add a small pat of butter to each breast while it rests and sprinkle with chopped parsley. Slice against the grain and serve with lemon wedges.
