Ingredients for Kewpee Olive Burger Sauce

A handful of simple ingredients blend into this tangy, umami-packed burger sauce in minutes.

The olives are non-negotiable here—Manzanilla with pimentos from any grocery store works, but I grab mine in bulk at Sam’s Club for the best price. Mayonnaise is the base, so use a brand you like (I’m partial to Hellmann’s). The ketchup and mustard balance sweet and tangy, but any standard versions will do. Freshness matters most with the vinegar—check the bottle hasn’t been sitting forever.

No green olives? Black olives work in a pinch (drain and chop the same). Short on Worcestershire? Soy sauce at half the amount adds similar depth. The paprika is flexible—sweet or smoked both work. If you’re out of white vinegar, apple cider vinegar is a fine swap. The sugar can be skipped if you prefer less sweetness, but it rounds out the flavors beautifully.

This keeps 2 weeks in the fridge in an airtight container (glass jars are perfect). The flavors actually deepen after a day, so make it ahead if you can. Freezing isn’t ideal—it can separate—but if you must, use ice cube trays for single-serving portions.

Step-by-Step Instructions for Kewpee Olive Burger Sauce

Here’s the method. Straightforward, tested, works every time.

Step 1: Finely Chop the Green Olives

Start by finely chopping the 0.5 cup Green Olives. I like to place them on a cutting board and rock my chef’s knife back and forth over them until they’re uniformly small—about the size of a grain of rice. This ensures every bite of your sauce has that briny olive flavor distributed evenly.

If you prefer, you can pulse them in a food processor, but be careful not to over-process into a paste. You want distinct olive pieces, not a smooth puree. Transfer the chopped olives to a medium mixing bowl.

Step 2: Combine Wet Ingredients for Creamy Base

Add the 1 cup Mayonnaise, 0.25 cup Ketchup, 1 tbsp Yellow Mustard, and 1 tbsp White Vinegar to the bowl with the olives. Stir these together gently with a silicone spatula or wooden spoon until the mixture is smooth and uniform in color.

The mayonnaise creates the creamy foundation, while the ketchup and mustard add tang and depth. The vinegar brightens everything up, balancing the richness. Don’t rush this step—make sure all ingredients are fully incorporated.

Step 3: Add Sweet and Savory Seasonings

Next, stir in the 1 tsp Granulated Sugar, 0.5 tsp Garlic Powder, 0.5 tsp Onion Powder, 0.25 tsp Paprika, and 1 tsp Worcestershire Sauce. Each of these plays a crucial role—the sugar tames the acidity, the powders add savory depth, the paprika gives a subtle warmth, and the Worcestershire brings umami.

Taste as you go and adjust if needed, though I’ve found this balance works perfectly. The sauce should taste tangy, slightly sweet, and savory with a hint of smokiness from the paprika.

Step 4: Chill and Let Flavors Meld

Cover the bowl with plastic wrap or transfer the sauce to an airtight container. Refrigerate for at least 1 hour to let the flavors develop and meld together. This resting time is key—the olives will soften slightly, and all the seasonings will harmonize.

I often make this the night before I plan to use it, as the flavor improves even more with a little extra time. The sauce will keep in the fridge for up to 1 week, so you can make a batch ahead for your next burger night.

Flavor Customization for This Dish

Spicy Kick

Add ½ tsp cayenne pepper or 1 tsp sriracha for a spicy version that pairs perfectly with grilled chicken burgers. The heat balances the briny olives beautifully. I love this variation on a summer evening. 🌶️

Smoky Depth

Swap the paprika for ½ tsp smoked paprika or add ½ tsp liquid smoke for a BBQ-inspired twist. This works wonderfully with beef burgers and adds that classic cookout flavor.

Herb-Infused

Stir in 1 tbsp fresh dill or 1 tsp dried oregano for a Mediterranean flair. The herbs complement the olives and add freshness to every bite.

Sweet Variation

Increase the sugar to 2 tsp or add 1 tbsp honey for a sweeter sauce. This version is great for kids or anyone who prefers a milder, sweeter profile.

Extra Umami

Boost the umami by adding 1 tsp soy sauce or ½ tsp fish sauce. This deepens the savory notes and makes the sauce even more addictive.

I often use this version for meatloaf sandwiches. ✨

Creamier Texture

For a thicker, richer texture, add 2 tbsp Greek yogurt or 1 tbsp sour cream. This makes the sauce even more luxurious and perfect for dipping fries.
