Step 1

Mix butter, lemon juice, paprika, oregano, garlic salt, salt, and pepper together in a bowl or resealable bag. Add chicken breasts and marinate in the refrigerator for 3 to 4 hours.

Step 2

Preheat the oven to 325 degrees F (165 degrees C). Transfer chicken to a baking dish, skin-side up. Pour marinade around the chicken.

Step 3

Bake, uncovered, in the preheated oven until no longer pink in the centers and juices run clear, about 45 minutes. An instant-read thermometer inserted near the bone should read 165 degrees F (74 degrees C).
