Prepare the chicken: Pat the chicken dry. If the breasts are very thick, gently flatten them to an even thickness for more consistent cooking.
Season the chicken: Season both sides with paprika, black pepper, and salt.
Heat the skillet: Place a large skillet over medium heat and add the olive oil.
Cook the chicken: Place the chicken in the hot skillet. Cook for about 5–7 minutes on the first side, without moving it too much.
Flip and finish cooking: Turn the chicken and continue cooking until the thickest part reaches 165°F (73.9°C).
Add the garlic: Add the chopped garlic during the final few minutes. Stir carefully so it becomes fragrant without burning.
Add lemon: Take the skillet off the heat and squeeze fresh lemon juice over the chicken.
Rest and serve: Let the chicken rest for a few minutes, then garnish with parsley and serve.
