Cut each chicken breast in half lengthwise to create four chicken cutlets of even thickness
In a small bowl, combine flour, lemon pepper seasoning, garlic powder, and salt, then whisk together
Sprinkle the seasoning mixture all over the chicken and rub it in with your hands
Heat a large skillet over medium heat and add 2 tablespoons of olive oil
Once the oil is hot and shimmering, add the chicken to the pan in a single layer
Sauté the first side for about 5 minutes until golden brown
Flip the chicken and cook for another 4-6 minutes until the internal temperature reaches 165°F
Transfer the chicken to a plate
Turn off the heat and add 4 tablespoons of butter to the hot pan, scraping to get up all the browned bits
Add the lemon zest and fresh lemon juice to the pan
Add 1 tsp lemon pepper seasoning and 2 tsp chopped fresh parsley
Stir everything to combine
Add the cooked chicken back to the pan and coat each piece in the sauce
Serve the chicken with the pan sauce spooned over the top, garnished with lemon slices and fresh parsley
