Ingredients You Need for Del Taco Secret Sauce
- 1 cup mayonnaise
- 2 tablespoons ketchup
- 1 tablespoon yellow mustard
- 1 tablespoon pickle relish
- 1 teaspoon white vinegar
- 1 teaspoon smoked paprika
- 1 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/2 teaspoon chili powder
- 1 teaspoon hot sauce
- Pinch of salt
- Pinch of black pepper
Step-by-Step Guide
1. Add the mayonnaise
Place the mayonnaise into a medium mixing bowl carefully before adding other ingredients. The mayonnaise creates the creamy smooth base for the secret sauce. Use full-fat mayonnaise for the richest flavor and best creamy texture possible.
2. Mix in ketchup and mustard
Add ketchup and yellow mustard into the bowl with mayonnaise carefully. Stir gently using a whisk until smooth and evenly combined. These ingredients create the classic tangy sweet flavor found in many popular fast-food style sauces.
3. Add pickle relish
Spoon the pickle relish into the sauce mixture slowly before stirring carefully. The relish adds sweetness, crunch and bright tangy flavor. This small ingredient helps give the sauce its signature restaurant-style taste and texture balance beautifully.
4. Add the seasonings
Sprinkle smoked paprika, garlic powder, onion powder, chili powder, salt and black pepper into the bowl evenly. Stir thoroughly so every spice combines properly. These seasonings create smoky savory depth and slightly spicy flavor throughout the creamy sauce.
5. Pour in vinegar and hot sauce
Add white vinegar and hot sauce carefully while whisking the mixture slowly. Vinegar brightens the flavor while hot sauce adds mild heat. The sauce should taste creamy, tangy, smoky and slightly spicy after mixing completely together.
6. Whisk until smooth
Continue whisking the sauce until smooth and creamy without lumps remaining. Scrape the bowl sides using a rubber spatula if necessary. Proper mixing helps distribute every ingredient evenly throughout the homemade secret sauce mixture for balanced flavor.
7. Taste and adjust
Taste the sauce using a spoon before serving. Add extra hot sauce for more heat or more relish for sweetness. Adjusting the ingredients slightly helps create perfect flavor based on your personal preference and family taste.
8. Chill before serving
Cover the sauce and refrigerate for at least thirty minutes before serving. Chilling helps the flavors blend together more deeply. The sauce becomes thicker, richer and more flavorful after resting inside the refrigerator for a short time.
9. Serve and enjoy
Serve the Del Taco secret sauce with tacos, burgers, fries, wraps, sandwiches or chicken tenders immediately. The creamy smoky flavor works beautifully with many foods. Keep extra sauce nearby because everyone usually asks for another spoonful quickly.
