Del Taco White Sauce Recipe: Tangy Cream Drizzle for Tacos

This creamy sauce captures the signature tangy flavor that makes Del Taco’s dishes unforgettable. The balance of bold seasonings and smooth texture elevates any taco night at home.

With just a handful of pantry staples and 5 minutes of mixing, you can recreate this restaurant-quality drizzle. Store it in the fridge for up to a week to use on everything from burritos to fries.

Ingredients for Del Taco White Sauce

Nine simple ingredients blend into that signature creamy tang you crave.

The mayo base is key—Duke’s or Hellmann’s give the creamiest texture. I grab mine from Walmart or any grocery store. Sour cream adds richness, so don’t sub with Greek yogurt here (it changes the vibe). Buttermilk ties it all together—cultured is best, but regular works in a pinch.

No buttermilk? Milk plus 1 tsp vinegar (let it sit 5 minutes) gets you close. Skip the dill if you’re not a fan—dried parsley works too. Want more tang? Add an extra splash of vinegar. The garlic and onion powders are doing the heavy lifting for that signature flavor, so don’t skip them.

This keeps 1 week in the fridge, but honestly it’s gone in days. Store in a sealed jar. Doesn’t freeze well—separates when thawed. Perfect for tacos, burritos, or even as a fry dip.

Step-by-Step Instructions for Tangy Cream Drizzle

This comes together in minutes—just whisk, taste, and adjust to your liking.

Step 1: Combine the Creamy Base

In a medium bowl, add the 1 cup Mayonnaise and 0.5 cup Sour Cream. I always use full-fat versions here for that rich, velvety texture this sauce is known for. The mayonnaise gives it body while the sour cream adds a subtle tang.

Whisk them together until completely smooth and no streaks remain. You want a uniform base before adding the other ingredients—this ensures everything incorporates evenly and prevents any lumps of dry spices.

Step 2: Add the Liquid Ingredients

Pour in the 0.25 cup Buttermilk (make sure you’ve shaken it well first) and the 1 tbsp White Vinegar. The buttermilk adds a light, slightly tangy flavor, while the vinegar gives it that signature zing.

Whisk again until fully combined. The mixture should look creamy with a slight sheen. If it seems too thick at this point, don’t worry—the buttermilk will thin it out just enough as you continue mixing.

Step 3: Season with Dry Ingredients

Sprinkle in the 1 tsp Garlic Powder, 1 tsp Onion Powder, 0.5 tsp Salt, 0.5 tsp Sugar, and 0.5 tsp Dried Dill. I add them all at once to keep things simple, but make sure they’re evenly distributed across the surface of the sauce.

Whisk vigorously for about 30 seconds until no dry spots remain. The sugar balances the acidity from the vinegar and buttermilk, while the garlic and onion powders add depth. The dill gives it that subtle herby note that makes it irresistible.

Step 4: Adjust and Chill

Give it a taste and adjust the seasoning if needed. If you want it tangier, a splash more vinegar works. Prefer it sweeter? A pinch more sugar does the trick. This is your chance to make it perfect for your palate.

Transfer the sauce to a jar or airtight container and refrigerate for at least 30 minutes before using. This chilling time lets the flavors meld together, and the sauce will thicken slightly. It’s ready when it coats the back of a spoon smoothly.

Store in the fridge for up to 5 days, and give it a good stir before each use.
