Pat the chicken breasts dry using paper towels. If needed, pound them to an even thickness for even cooking.
Season both sides of the chicken with salt, black pepper, paprika, and oregano. Gently press the seasoning into the chicken.
Heat a large skillet over medium heat for 1 to 2 minutes. Add olive oil and allow it to heat until slightly shimmering.
Place the chicken into the pan, leaving space between each piece. Cook undisturbed for 5 to 7 minutes until a golden crust forms.
Flip the chicken and cook the other side for another 5 to 7 minutes until fully cooked. Remove the chicken and set aside.
Reduce heat to medium-low. Add butter to the same pan and let it melt slowly.
Add minced garlic and cook for 30 seconds to 1 minute until fragrant, stirring gently to prevent burning.
Pour in lemon juice and add lemon zest. Stir well and let the sauce simmer for 1 to 2 minutes.
Return the chicken to the pan. Spoon the sauce over the chicken and let it simmer for 2 to 3 minutes.
Sprinkle chopped parsley on top and let the chicken rest for a few minutes before serving.
