Outback Steakhouse® Ranch Salad Dressing This always-popular growing restaurant chain makes a tasty version of creamy ranch dressing for its house and Queensland salads. To get the same unique flavor and creaminess of the original at home, mates, you'll need just one teaspoon of Hidden Valley ranch salad dressing mix swimming in there with the mayo and buttermilk and other spices. Since there's three teaspoons of dressing mix per packet, you'll be able to stretch one envelope three times as far, by crackey! 1 teaspoon Hidden Valley Ranch salad dressing mix (buttermilk recipe) 1 cup mayonnaise 1/2 cup buttermilk 1/4 teaspoon coarse grind black pepper 1/8 teaspoon paprika 1/8 teaspoon garlic powder = 1.
