Of course it's a copy cat recipe. Be careful if you get copy cat recipes on line. Some of them are awful. This one I have used for several years and everyone remarks that my steaks taste like Outback Steak House.
This is a great way to do hamburgers or turkey burgers, also.
Outback Steak House-Steak Seasoning
1 envelope Taco Seasoning
1 envelope Good Seasoning Italian Dressing Mix
1 tablespoon olive oil, approx.
1 bottle Coco Cola (Did I say Pepsi? No.)
Rub oil in steak and coat with seasoning mixture.
Pour Coca Cola around (not over) steaks in a deep glass or plastic container. Seal with plastic wrap or tight fitting lid.
Refrigerate for 24 hours
Drain and grill or broil to your likeness. Basting with marinate if you like.
COOK'S NOTE: If using a less tender steak, such as flank, pierce steak several times with a fork before rubbing in oil and coating with seasoning.
