Heat the oven to 400°F. Lightly oil a 9×13-inch baking dish.
Pat the chicken dry with paper towels (dry chicken browns better, even in a bake).
Whisk the olive oil, lemon juice, garlic, Italian seasoning, 1 tsp salt, and 1/2 tsp pepper in a small bowl.
Place the chicken in the dish in a single layer and pour the mixture over, turning each breast to coat.
Bake 22 to 28 minutes, until the thickest part reads 165°F on a meat thermometer.
Rest 5 minutes (the juices redistribute — don't skip this), then spoon the pan juices over the top.
