Step 1

Place one of the chicken pieces between two plastic sheets or in a large plastic bag. Flatten to an even thickness, about ½-inch thick. Repeat with the remaining pieces.Alternatively, for pieces 1-inch thick or larger, cut in half horizontally. This should create eight ½-inch thick pieces.

Step 2

In a small bowl, combine kosher salt, black pepper, paprika (if using), garlic powder, onion powder, and Italian seasoning (if using).

Step 3

Use paper towels to pat dry both sides of the chicken to remove excess surface moisture.

Step 4

Evenly sprinkle both sides of the chicken with the seasoning mix, about ¼ to ½ teaspoon per side.

Step 5

Heat a large skillet over medium heat. Add olive oil, once hot and shimmering but not smoking. Add the chicken breasts presentation side down. Use tongs to press down into the pan for maximum contact. Cook until golden brown, about 5 to 7 minutes.

Step 6

If the chicken is very large after flattening, work in batches cooking two pieces at a time. Clean the pan in between if needed.

Step 7

Flip the chicken over and add the butter. Swirl the pan to melt and evenly distribute. Occasionally baste the meat with the butter. Cook until the internal temperature reaches 160 to 165ºF (71 to 74ºC), about 5 to 7 minutes. Transfer to a clean plate to rest for 5 minutes.

Step 8

Serve whole pieces of chicken breast, or slice crosswise into strips or dice into cubes.
