The mayonnaise is your base, so Duke’s or Hellmann’s give the best texture—avoid light versions as they lack richness. Green olives should be the pimiento-stuffed kind for authentic flavor. Most grocery stores carry them in the condiment aisle. For pickles, Heinz or Vlasic dill chips work perfectly (don’t drain them—use that briny juice for extra tang).

No green olives? Manzanilla olives work in a pinch. Out of pickles? Pickle relish at a 1:1 ratio saves the day. Mustard can be swapped for Dijon at half the amount for a sharper bite. The vinegar is non-negotiable for that signature Kewpee tang, but apple cider vinegar works if that’s what you have.

This keeps beautifully in a sealed jar for up to 2 weeks. The flavors actually deepen after 24 hours, so make it ahead if you can. Stir before each use—the olives and spices tend to settle.

Step-by-Step Instructions for Kewpee Olive Burger Sauce

This straightforward method ensures a perfectly balanced sauce with the signature tangy olive flavor.

Step 1: Prepare the Vegetable Components

Begin by finely chopping the 0.5 cup Green Olives until they reach a consistent, small dice. I prefer using a chef’s knife for this task, as it gives you better control over the texture than a food processor, which can turn olives into a paste.

Next, finely mince the 2 tbsp Dill Pickles with their juice. The juice adds an extra layer of tanginess that complements the olives beautifully. Combine both chopped elements in a small mixing bowl and set aside. This preparation ensures even distribution throughout the sauce.

Step 2: Combine the Wet Ingredients

In a medium bowl, add the 1 cup Mayonnaise, 1 tbsp Yellow Mustard, and 1 tbsp White Vinegar. The full-fat mayonnaise provides the creamy base that binds all the flavors together, while the mustard and vinegar introduce the bright, tangy notes characteristic of this sauce.

Whisk these ingredients together until fully incorporated and smooth. You should see no streaks of mustard or vinegar—just a uniform, pale yellow mixture. This step establishes the sauce’s creamy foundation before adding the remaining components.

Step 3: Incorporate the Dry Ingredients

To the wet mixture, add the 1 tsp Granulated Sugar, 0.5 tsp Garlic Powder, 0.5 tsp Onion Powder, and 0.25 tsp Paprika. The sugar balances the acidity from the vinegar and pickles, while the garlic and onion powders deepen the flavor profile with subtle savory notes.

Whisk again until all the dry ingredients are fully dissolved and distributed. The paprika adds a hint of color and a mild smokiness that rounds out the sauce’s complexity. Taste at this stage—you should detect a harmonious blend of tangy, creamy, and slightly sweet elements.

Step 4: Fold in the Chopped Olives and Pickles

Add the prepared 0.5 cup Green Olives and 2 tbsp Dill Pickles to the sauce base. Using a silicone spatula, fold them in gently but thoroughly. This ensures the chunks are evenly dispersed without breaking them down further, maintaining a pleasant texture in every bite.

The olives should be visible throughout the mixture, providing bursts of briny flavor. The pickles, with their juice, will soften slightly in the sauce but retain enough texture to add interest. Let the sauce rest for 10-15 minutes before serving to allow the flavors to meld together fully.

Step 5: Adjust and Serve

Give the sauce a final stir and check the consistency. If it seems too thick, you can thin it slightly with a teaspoon of cold water, though the mayonnaise base typically yields the perfect spreadable texture. Taste once more and adjust seasoning if needed, though the measured ingredients should provide an ideal balance.

Transfer to an airtight container and refrigerate if not using immediately. This sauce keeps well for up to 5 days in the refrigerator. Serve chilled or at room temperature on burgers, sandwiches, or as a dip for fries to experience that authentic Kewpee tang.

Storing and Reheating kewpee olive burger sauce

Refrigerator Storage

Transfer your sauce to an airtight glass jar—I love using 8-ounce mason jars for easy scooping. Store at 40°F or below for up to 2 weeks. The flavors actually deepen after 24 hours, so make it ahead if possible. ❄️

Freezer Storage

This sauce freezes well for up to 3 months without texture changes. Use ice cube trays for portion control, then transfer frozen cubes to a freezer bag. Thaw overnight in the fridge before using.

Thawing Method

Move frozen sauce to the refrigerator 12-24 hours before needed. For quick thawing, place the sealed container in a bowl of cold water, changing water every 30 minutes until soft.

Stirring Before Use

Always stir vigorously before serving as the olives and spices settle. I use a small whisk to reincorporate everything smoothly. If too thick, thin with 1 tsp cold water at a time.

Room Temperature Serving

For best flavor, let the sauce sit at room temperature for 15-20 minutes before serving. This takes the chill off and enhances the creamy texture. Perfect for burger night! 💛
