Melt the Butter: Melt 3 tablespoons of butter in a large skillet over medium heat.
Add the Chicken: Place the chicken breast halves into the melted butter, arranging them in the skillet so they can cook evenly.
Season the Chicken: Sprinkle the chicken with garlic powder, seasoning salt, and onion powder, adjusting the seasonings to taste.
Sauté the First Side: Cook the chicken in the hot butter for 7 to 10 minutes, allowing it to sauté until the outside is cooked and the chicken is no longer pink in the center.
Turn and Continue Cooking: Turn the chicken breasts over and sauté the other side for another 7 to 10 minutes, continuing until the juices run clear and the chicken is fully cooked.
Check the Temperature: Insert an instant-read thermometer into the center of a chicken breast. The internal temperature should reach at least 165°F (74°C). Serve Hot: Remove the fully cooked chicken from the skillet and serve hot.
