copycat recipe olive garden salad dressing Olive Garden Salad Dressing 1/2 C. mayonnaise 1/3 C. white vinegar 1 tsp. vegetable oil 2 Tbsp. corn syrup 2 Tbsp. Parmesan cheese 2 Tbsp. Romano cheese 1/4 tsp. garlic salt 1/2 tsp. Italian seasoning 1/2 tsp. parsley flakes 1 Tbsp. lemon juice One of the best things about the Olive Garden is their never-ending salad bowl. They sell the house dressing right there at the restaurant, but I thought it would be easier (and more frugal) to try and duplicate the Olive Garden salad dressing at home. A quick internet search turned up dozens of recipes, most of which were exactly like the one above. What’s nice about the Olive Garden salad dressing recipe is that the ingredients are readily available. In fact, you may already have them in your refrigerator/pantry. Toss with fresh tomatoes, Vidalia onions, black olives, croutons, pickled pepperoncini and freshly grated Parmesan cheese to give you a true Olive Garden restaurant experience.
