Combine Base Ingredients
In a large mixing bowl, combine 1/2 cup mayonnaise, 2 tsp Dijon mustard, 2 tsp Worcestershire sauce, grated garlic, 3 Tbs lemon juice, salt, and pepper, and whisk to combine thoroughly. This creates the flavorful foundation of your dressing with a balance of creamy, tangy, and savory elements.
Incorporate Olive Oil
While whisking vigorously, slowly drizzle in 1/2 cup olive oil. Once all of the olive oil is incorporated, continue whisking until the mixture is well emulsified and smooth. The slow addition creates a stable emulsion that prevents separation and gives the dressing its silky texture.
Add Parmesan
Add 1/2 cup freshly grated parmesan cheese and whisk together until fully combined. The cheese adds depth and umami flavor while helping to thicken the dressing to the perfect consistency.
Store Properly
Transfer the finished dressing to a mason jar, cover with a lid, and refrigerate until ready to use. Proper storage helps the flavors meld together and ensures the dressing stays fresh.
