Copycat Del Taco Secret Sauce
My husband used to drive twenty minutes out of his way just to get Del Taco — all because of the sauce. Once I realized how much that Copycat Del Taco Secret Sauce had a hold on him, I made it my mission to figure it out at home.
Four attempts and a lot of taste testing later, I landed on a version that is tangy, pickle-forward, and genuinely addictive in all the right ways. He took one bite and told me he did not need to make that drive anymore, which I consider a win.
The ingredients are simple pantry staples and the whole thing comes together in about five minutes. No special equipment, no complicated technique — just a bowl and a spoon.
Once you make this once, you will want to put it on everything in your kitchen.

How To Make Copycat Del Taco Secret Sauce
Combine wet ingredients
In a medium bowl, whisk together mayonnaise, ketchup, pickle juice, and white vinegar until smooth and well combined.
Add dry seasonings
Whisk in sugar, garlic powder, onion powder, paprika, and mustard powder until no lumps remain.
Season and taste
Add cayenne pepper if using, then taste and adjust seasonings. Add more pickle juice for tang or sugar for sweetness as needed.
Rest and serve
Let the sauce rest for 15 minutes to allow flavors to meld, then transfer to a squeeze bottle or jar for easy serving.
Pro Tips For The Best Results
- Whisk dry ingredients into wet first — Prevents clumping and ensures sugar and spices dissolve completely.
- Rest before serving, always — Even 15 minutes off the whisk makes the flavors noticeably rounder and more cohesive.
- Add cayenne last, one pinch at a time — Heat builds fast in a cold sauce — go slow and taste as you go.

Common Mistakes To Avoid
- Not letting the sauce rest before serving — Allow at least 15 minutes for flavors to develop and meld together.
- Using low-quality pickle juice — Choose pickle juice from good dill pickles – it’s the star ingredient.
- Adding too much cayenne at once — Start with a pinch and add more gradually to control the heat level.
- Not whisking thoroughly enough — Whisk until completely smooth to prevent any lumps or separation.
Make Ahead and Storage Tips
This sauce keeps beautifully in the refrigerator for up to two weeks stored in an airtight jar or container — the flavor only gets better as it sits.
For the best results, make it at least 24 hours ahead of serving so the pickle tang, spices, and mayo have time to fully come together.
Store in a squeeze bottle in the fridge for easy taco nights — it makes drizzling fast and cleanup even faster.
To freeze for longer storage, pour into an ice cube tray and freeze solid, then transfer to a freezer bag — individual portions last up to three months and thaw in minutes.
What To Serve With Copycat Del Taco Secret Sauce
- Drizzle over tacos, burritos, or quesadillas for authentic Del Taco flavor
- Use as a dipping sauce for crispy french fries (like these Copycat Del Taco Beer Battered Fish Tacos that pair perfectly with this sauce) or onion rings
- Spread on burgers or sandwiches for a tangy kick
- Serve alongside grilled chicken or fish for a zesty finishing sauce
Delicious Variations To Try
- Smoky Chipotle Version — Add 1/2 teaspoon chipotle powder and a few drops of adobo sauce from a can of chipotles for deep smoky heat that pairs perfectly with grilled chicken tacos.
- Sweet and Spicy — Swap the granulated sugar for honey and add 1 teaspoon of your favorite hot sauce for a sauce that hits sweet and spicy at the same time.
- Burger Sauce Remix — Stir in 1 tablespoon finely minced dill pickles and a teaspoon of Dijon mustard to turn this into a thick, chunky spread that is incredible on smash burgers.

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.
