Equipment

  • Medium mixing bowl or 4-cup glass measuring cup
  • Whisk
  • Blender or immersion blender (optional but recommended)
  • Glass jar or airtight bottle for storage

Ingredients

  • 1/2 cup Mayonnaise Use a high-quality, full-fat brand like Hellmann's or Duke's for best flavor and emulsion.
  • 1/3 cup Buttermilk Shake well before measuring. For a thicker dressing, start with 1/4 cup.
  • 1/4 cup Grated Parmesan cheese Freshly grated from a block is ideal for flavor and smooth texture.
  • 2 tbsp White wine vinegar Red wine vinegar can be substituted for a bolder flavor.
  • 1 tbsp Extra virgin olive oil
  • 1 tsp Italian seasoning A blend of dried oregano, basil, thyme, and rosemary.
  • 1 tsp Garlic powder Not garlic salt. This provides consistent flavor without raw bite.
  • 1 tsp Onion powder
  • 1/2 tsp Dried oregano Additional oregano boosts the classic Italian flavor profile.
  • 1/2 tsp Salt Fine sea salt or kosher salt.
  • 1/4 tsp Black pepper Freshly ground is best.
  • 1/4 tsp Red pepper flakes Optional, for a subtle kick.

Instructions

  • Combine all ingredients in a medium mixing bowl or a large glass measuring cup with a spout. Using a whisk, vigorously whisk the mixture for 60-90 seconds until it is completely smooth, creamy, and well-combined. Trust me, this initial whisking is crucial for creating a stable emulsion and preventing separation.
  • Taste the dressing and adjust the seasoning. You may want to add an extra pinch of salt, a squeeze of lemon juice for brightness, or a splash more vinegar for tang. Remember, the flavors will meld and intensify slightly after chilling.
  • For the absolute smoothest texture, transfer the dressing to a blender or use an immersion blender. Blend on medium speed for 15-20 seconds until luxuriously creamy and uniform. This step is optional but highly recommended for a professional-quality result.
  • Pour the finished dressing into a clean glass jar or airtight bottle with a lid. Seal the container and refrigerate for at least 1 hour before serving. This chilling time allows the dried herbs to rehydrate and the flavors to fully marry, creating a more complex and harmonious taste.
  • Before serving, give the dressing a good shake or stir. Drizzle generously over your favorite salad, use as a vegetable dip, or as a sandwich spread. Step back and admire your homemade creation—it’s ready to elevate any meal.

Notes

Chef's Tips:
• For a vegan version, use vegan mayonnaise, unsweetened plant-based milk with a squeeze of lemon (in place of buttermilk), and nutritional yeast instead of Parmesan.
• A common mistake is using garlic salt instead of garlic powder, which can make the dressing overly salty. Always check your labels.
• This dressing is fantastic as a marinade for chicken or a sauce for pasta salad. Its versatility is a huge bonus.
Food Safety:
• Due to the dairy content (buttermilk, mayonnaise, Parmesan), this dressing must be stored in the refrigerator at all times.
• Use clean utensils when scooping from the jar to prevent bacterial contamination and extend shelf life.
