How to Make This Creamy Italian Dressing
Follow these simple, step-by-step directions. The method is also included in the recipe card below.
Step 1: Combine the Ingredients
In a medium bowl, add light olive oil, mayo, red wine vinegar, grated Parmesan, lemon juice, Italian seasoning, mustard powder, garlic powder, salt, and pepper. Whisk until the mixture is smooth and creamy, making sure the mayo is fully incorporated.
Step 2: Season and Rest
Taste and adjust the dressing to your preference: add more vinegar or lemon for extra tang, or more mayo for a thicker, creamier texture. Transfer to an airtight container and refrigerate for at least 30 minutes so the flavors meld.
Recipe Notes
Texture: For a thicker dressing, increase the mayo or add Greek yogurt. For a thinner consistency, add more olive oil or vinegar a tablespoon at a time.
Flavor adjustments: Increase garlic or Italian seasoning to make the dressing more garlicky or herb-forward. Try a homemade Italian seasoning blend for a fresher taste.
Sweetness: If you like a touch of sweetness, stir in 1 teaspoon of honey or maple syrup and adjust to taste.
