The Best Homemade Olive Garden Salad Dressing Recipe

Instructions:

1. In a medium mixing bowl, thoroughly whisk together the ice water, white wine vinegar, sugar, salt, oregano, basil, parsley, onion powder, garlic powder, and black pepper until the sugar and salt are mostly dissolved.
2. Add the mayonnaise and the finely grated Parmesan cheese to the bowl. Whisk vigorously until everything is completely smooth and combined into a thick, pale liquid.
3. Begin adding the vegetable oil very slowly, starting with just a thin, steady drizzle while whisking continuously and rapidly. This step is crucial for emulsion.
4. Once about half the oil is incorporated, you can slightly speed up the drizzle, but never stop whisking until all the oil is added. The mixture should thicken significantly and become opaque and creamy.
5. Taste the dressing and adjust seasoning, adding more salt, pepper, or vinegar if desired.
6. Transfer the finished dressing to an airtight container and refrigerate for at least 30 minutes before serving to allow the dried herbs to hydrate fully and the dressing to reach its final consistency.
