Quick answer

To make ranch, whisk three quarters of a cup each of mayonnaise and buttermilk with a tablespoon of chopped dill and chives, a teaspoon of dried parsley, half a teaspoon each of garlic and onion powder, a teaspoon of lemon juice, salt, and pepper. Rest it thirty minutes, thicker mayo ratio for dip.

What it is

What is ranch?

Ranch is a buttermilk dressing invented at an actual ranch, Hidden Valley near Santa Barbara, in the 1950s, and its formula was never complicated: creamy base, buttermilk tang, and a specific herb chord of dill, chives, and parsley over quiet garlic and onion. What the bottles lose is the fresh dairy snap, shelf-stable ranch cannot use real buttermilk, and that tang is most of the point.

The mayo-to-buttermilk ratio is the texture dial. Equal parts pours over salad, two-to-one mayo stands up as a dip, and a spoonful of sour cream in either direction adds body without changing the flavor line.

The recipe

3/4 cup
Mayonnaise
×
3/4 cup
Buttermilk

One to one mayo and buttermilk for dressing, two to one for dip. Dried herbs want a thirty-minute rest to hydrate, fresh herbs are ready immediately and taste greener.

Method

How do you make ranch?

  1. Whisk the mayonnaise smooth, then whisk in the buttermilk.
  2. Add the herbs, garlic, onion, lemon, salt, and pepper.
  3. Rest thirty minutes refrigerated, dried herbs need it, all versions improve with it.
  4. Taste: more lemon if flat, more buttermilk if too thick.
  5. Keeps five days refrigerated. Stir before each use.
The buttermilk is the recipe Every bottled ranch disappointment traces to fake tang. Real carton buttermilk, one to one with mayo, is the whole distance between bottle and restaurant.
Cook's notes

FAQ

Common questions.

Can I make ranch without buttermilk?

Yes: milk soured with a teaspoon of lemon juice for five minutes, or thinned plain yogurt. The flavor target is fresh dairy tang, anything that supplies it works.

How long does homemade ranch keep?

Five days refrigerated, its clock is the buttermilk. If it thins after a few days, whisk in a spoonful of mayo.

What herbs are in ranch?

Dill, chives, and parsley are the signature chord, over garlic and onion powder. Dill is the one you cannot skip without losing the ranch identity.
