This creamy buttermilk ranch dressing tastes way better than the packet mix version!  This recipe is super quick to make; just mix together mayo, sour cream, lemon, garlic, spices, and buttermilk.  You won’t want to go back to store bought dressing again!



  • 3/4 cup Duke’s mayo (168g)
  • 1/2 cup sour cream (120g)
  • 2 tablespoons freshly squeezed lemon juice (15 ml)
  • 1 tablespoon minced garlic
  • 1 teaspoon dried parsley flakes
  • 1/2 teaspoon dried dill
  • 1/2 teaspoon onion powder
  • 1/4 teaspoon salt
  • 1/4 teaspoon white pepper
  • 2 tablespoons buttermilk (30 ml)


  1. Measure the mayo, sour cream, lemon juice, garlic, and spices into a medium bowl and whisk until smooth.
  2. Taste and adjust the amount of lemon, garlic, and seasonings to your personal taste.
  3. Thin the dressing with the buttermilk until it is your preferred consistency.
  4. Eat immediately or refrigerate for up to 1 week.


  • Fresh garlic and lemon juice is the secret to a great-tasting ranch.
  • Substitute Greek yogurt for the sour cream.
  • Adjust seasonings to taste.
  • Add the buttermilk at the end.  This is just to thin out the dressing and add extra tang.
  • No buttermilk?  Use the separated liquid in the sour cream carton, whole milk, or heavy cream instead, along with an extra dash of lemon juice.
