Copycat Del Taco Secret Sauce
My husband used to drive twenty minutes out of his way just to get Del Taco because of their secret sauce. I finally decided to figure out what made that tangy, pickle-forward sauce so addictive after watching him eat it by the packet. Four attempts later I had my copycat Del Taco secret sauce recipe that tastes so close he stopped making those drives.

Frequently Asked Questions
How long does homemade Del Taco secret sauce last?
The sauce will keep in the refrigerator for up to 2 weeks when stored in an airtight container. Always check for any off smells before using.
Can I make this sauce without pickle juice?
Pickle juice is essential for the authentic Del Taco flavor, but you can substitute with extra vinegar and a pinch of dill – though it won’t taste quite the same.
Why is my sauce too thin or too thick?
If too thin, add more mayonnaise gradually. If too thick, thin with a little more pickle juice or vinegar until you reach the desired consistency.
Can I use light mayonnaise instead of regular?
Yes, but the sauce will be thinner and less rich. You may need to add less liquid to achieve the right consistency.
What’s the best way to store the sauce?
Store in a squeeze bottle or mason jar in the refrigerator. Squeeze bottles make it easy to drizzle just like at Del Taco.
Can I freeze this secret sauce?
Mayonnaise-based sauces don’t freeze well as they separate when thawed. It’s best to make fresh batches as needed.
How do I know if I got the flavor right?
The sauce should be tangy from the pickle juice, slightly sweet, and have a creamy texture that coats food well without being too thick.
What foods work best with this sauce?
It’s perfect on tacos, burritos, french fries, burgers, grilled meats, and as a dipping sauce for fried foods – basically anywhere you want that Del Taco flavor.
