Homemade Lime Ranch Dressing

Pro tips

• Make lime mayonnaise at least 15 minutes ahead to allow lime flavors to fully develop before mixing with buttermilk.
• Whisk ingredients until completely combined and smooth; lumps from the seasoning mix indicate uneven distribution.
• Taste and adjust lime intensity by adding zest or juice gradually—lime can overpower quickly.
• Chill for at least 2 hours before serving; cold temperatures help flavors meld and improve dressing consistency.

Substitutions

• Buttermilk → sour cream thinned with milk (use 3/4 cup sour cream + 1/4 cup milk for tanginess)
• Lime mayonnaise → store-bought lime mayo or regular mayo + 2 tablespoons fresh lime juice + 1 teaspoon lime zest
• Restaurant-style ranch seasoning mix → homemade blend of dried herbs and garlic/onion powder

Storage & make-ahead

Store in an airtight glass container in the refrigerator for up to 7 days; flavors strengthen after 24 hours. Do not freeze.

Can I make this dressing without a ranch seasoning packet?

Yes. Mix 1 teaspoon each dried parsley and chives, 1/2 teaspoon each garlic powder, onion powder, and dill, plus salt and pepper to taste into the mayo and buttermilk.

How long does homemade lime ranch dressing keep?

Store in an airtight container in the refrigerator for up to 7 days. The flavors meld and intensify after 1 day.

What's the best way to make lime mayonnaise?

Stir fresh lime juice and lime zest into store-bought mayonnaise, or blend mayo with lime juice until smooth. Let sit 15 minutes for flavors to develop.

Can I use Greek yogurt instead of buttermilk?

Yes. Use 3/4 cup Greek yogurt and thin with 1/4 cup milk or water to reach desired consistency, as yogurt is thicker than buttermilk.

Is this dressing suitable for dairy-free diets?

Not as written. Use dairy-free mayo and a plant-based buttermilk substitute, though the flavor profile will differ slightly.
