Preheat your oven to 200°C (392°F).
Place each chicken breast on a cutting board and cover with plastic wrap. Use a meat pounder or rolling pin to gently pound each piece to about 1.5 cm thickness for even cooking.
In a small bowl, mix together the salt, pepper, thyme, garlic powder, and paprika to create a flavorful seasoning blend.
Rub each chicken breast with olive oil, then sprinkle generously with the spice mixture, pressing it into the meat with your hands for even coating.
Place the seasoned chicken breasts on a baking sheet lined with parchment paper, ensuring they are spaced apart for even heat distribution.
Bake in the preheated oven for 20-25 minutes, or until the internal temperature reaches 75°C (165°F). The chicken should be golden and slightly crisp on the edges.
Remove the chicken from the oven and let it rest for 5 minutes. This helps the juices redistribute, keeping the meat moist and tender.
Squeeze fresh lemon juice over the rested chicken or serve with your favorite sauce for an added bright flavor.
Slice the chicken breasts against the grain to serve, revealing a juicy, tender interior with a beautifully browned exterior.
