To prepare a simple and delicious Outback steak rub with 4.5 stars from 121 reviews as of 2015, combine 4 to 6 teaspoons salt, 4 teaspoons paprika, 2 teaspoons ground black pepper, 1 teaspoon onion powder and 1 teaspoon garlic powder. Add 1 teaspoon cayenne pepper, 1/2 teaspoon coriander and 1/2 teaspoon turmeric. Mix the ingredients, and rub mixture onto 4 pieces top sirloin steaks. Grill the steaks over medium heat for 20 minutes.
If desired, 4 pieces rib eye steaks can be substituted for the top sirloin steaks. Press down on the steaks with a spatula while grilling to sear the edges of the steak.
Let the steak come to room temperature an hour before cooking to prevent gray centers in the steaks. During this time, lightly stalk both sides of the steaks to promote water retention in the steak. Cut steaks to 1.5 to 2 inches thick to promote a charred outside and ideal temperature inside when the steak is done. Use hardwood charcoal to promote a smoky taste, and put the steaks on when the flames have died and coals glow orange. Allow the steak to rest for 10 minutes before serving to allow juices to spread, fibers to relax and flavors to be retained.
