Ingredients for kewpee olive burger sauce
Five minutes of chopping, ten minutes of mixing—this sauce is pure flavor magic.
| Ingredient | Amount | Notes |
|---|---|---|
| Kewpie Mayo 🥫 | ½ cup | Original Japanese mayo preferred |
| Pitted Green Olives 🫒 | ½ cup | Finely chopped, Kalamata or Manzanilla |
| Capers 🍯 | 2 tbsp | Finely chopped, not minced |
| Garlic Cloves 🧄 | 3 cloves | Minced, fresh preferred |
| Fresh Dill 🌿 | 2 tbsp | Chopped, stems removed |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For richness, fruity variety |
| Diamond Crystal Kosher Salt 🧂 | ½ tsp | Fine grain preferred |
| Freshly Ground Black Pepper 🌶️ | ¼ tsp | Freshly cracked preferred |
| White Vinegar 💧 | 1 tsp | For tangy brightness |
Kewpie mayo is non-negotiable here—its creamy, slightly sweet base is what makes this sauce sing. Grab the original Japanese version from Asian markets or World Market if you can't find it at regular grocery stores. The olives and capers are the briny stars, so pick fresh, pitted Kalamata or Manzanilla olives—none of that canned, mushy stuff. For capers, the tiny ones pack more punch. I always buy mine in glass jars at Trader Joe's—they keep forever and taste better than the plastic tubs. Fresh dill is ideal, but dried works at one-third the amount if you're in a pinch.
No Kewpie mayo? Hellmann's or Best Foods in a bind, but the flavor won't be quite the same. Swap Kalamata olives for Manzanilla or green olives—just adjust salt to taste since some are saltier. Love more garlic? Add another clove or two—it's the secret weapon for depth. The lemon juice is crucial for brightness, so don't skip it. For extra richness, drizzle in another tablespoon of olive oil at the end. Want it smoother? Pulse everything in a food processor for 10 seconds before mixing by hand.
This sauce tastes even better the next day as flavors meld. Keeps for 5-7 days in the fridge, sealed tight. For meal prep, portion into small jars—perfect for burger nights or sandwich spreads. Freezes for 3 months if you want to stock up. Pro tip: Add a pinch of sugar if you want to balance the tang, but honestly, it's already perfect as is.

Step-by-step instructions for Kewpie olive burger sauce
This bright, briny sauce comes together in minutes with just a few simple steps.
Finely Chop the Olives and Capers
Start by finely chopping the 0.5 cup pitted green olives using a sharp knife or food processor. You want tiny, even pieces that will blend seamlessly into the sauce. The olives should be about the size of a grain of rice—this ensures they distribute evenly and don't create texture in your burger sauce.
Next, finely chop the 2 tbsp capers using the same method. The capers should be even smaller than the olives, almost like a fine confetti. I like to use a small food processor for this step—it gives me consistent, tiny pieces without overworking the ingredients. Set both chopped olives and capers aside in separate small bowls.
Mince the Garlic and Prep the Fresh Dill
Peel the 3 cloves garlic and mince them as finely as possible. The goal is to create a paste-like texture that will blend smoothly into the sauce. I press the garlic cloves flat with the side of my knife first, then finely chop them. You should end up with about 1 teaspoon of minced garlic.
While the garlic works, chop the 2 tbsp fresh dill into tiny pieces, removing any stems. The dill should be finely chopped but not minced—think of it as a cross between a snip and a chop. The fresh dill will add a bright, herbal note that balances the briny olives and capers perfectly. Place the chopped dill in a small bowl.
Combine Wet Ingredients
In a medium bowl, whisk together the 0.5 cup Kewpie Mayo, 1 tbsp lemon juice, 1 tbsp extra-virgin olive oil, 1 tsp white vinegar, 0.5 tsp Diamond Crystal kosher salt, and 0.25 tsp freshly ground black pepper. The mixture should be smooth and well-combined, with no streaks of mayo or oil. This is the base of your sauce, so take your time to make sure everything is fully incorporated.
Here's the thing—Kewpie Mayo is thicker than regular mayo, so don't be tempted to add extra liquid. The sauce will emulsify perfectly with the ingredients you have. If it looks too thick, we'll adjust it in the next step. The key is to let the flavors meld together before adding the chopped ingredients.
Fold in the Chopped Ingredients
Using a silicone spatula, gently fold in the chopped olives, capers, minced garlic, and fresh dill. Start by adding about half of each ingredient, mixing just until combined, then add the remaining ingredients. Be careful not to overmix—you want the olives and capers to remain distinct but evenly distributed throughout the sauce.
Taste the sauce at this point. It should be bright, tangy, and slightly briny, with a hint of garlic and dill. If it needs more acidity, add a pinch more of the white vinegar or a squeeze of lemon juice. If it needs more salt, add a tiny pinch of the kosher salt. Remember, you can always adjust, but you can't take it out once it's in.
Rest and Adjust the Texture
Let the sauce sit at room temperature for 5-10 minutes. This resting period allows all the flavors to meld together and the sauce to come to the perfect consistency. The Kewpie Mayo will thicken slightly, and the flavors will deepen.
After resting, check the texture. If the sauce is too thick, whisk in 1 teaspoon of water at a time until it reaches a smooth, spoonable consistency—it should coat the back of a spoon but still be pourable. If it's too thin, let it sit for another 5 minutes or chill it in the refrigerator for 15-20 minutes to thicken. Once you've got the perfect texture, your sauce is ready to use!
Pro Tips For Making Kewpee Olive Burger Sauce
- Pulse, Don’t Blend: Use a food processor and pulse the olives, capers, and garlic in short bursts—no more than 3 seconds at a time. I learned this the hard way after turning my first batch into a sad, olive paste. You want texture, not a smoothie.
- Rinse Capers First: Drain and rinse capers under cold water before adding them to the mix. They’re packed in brine, and skipping this step means your sauce will taste like a pickle jar exploded. Trust me, the flavor balances better when they’re clean.
- Mince Garlic Coarse: Chop your garlic cloves into rough, uneven pieces—no need for minced perfection. Finely minced garlic burns faster and can turn bitter, while larger chunks add a nice, bright punch without overpowering. (Yes, even if you’re impatient like me.)
- Add Dill Last: Toss in the fresh dill after everything else is mixed, then give it a quick stir. This keeps the leaves bright and vibrant instead of turning them into sad, wilted confetti. If you’re using dried dill, halve the amount—it’s way more concentrated.

Heart-Healthy Fats
The extra-virgin olive oil in this recipe contributes monounsaturated fats, which are linked to improved heart health when consumed in moderation. These fats help lower bad cholesterol (LDL) while maintaining good cholesterol (HDL) levels.
Using 1 tablespoon provides about 14 grams of healthy fats—perfect for balancing the briny flavors without adding saturated fats found in many commercial sauces.

Versatile Nutrition
This sauce works as a dip, spread, or condiment, making it adaptable to various dietary needs. For a lighter version, reduce the mayo to ¼ cup and add an extra 1 tablespoon of lemon juice to maintain brightness.

Frequently asked questions
Can I make this sauce without Kewpie mayo?
You can substitute with regular mayo, but the flavor won't be identical. For the closest match, use Hellmann's or Best Foods and add ½ teaspoon sugar to balance the tang. The sauce will still taste great—just less rich and slightly sweeter.
How do I adjust the texture if it's too thick or too thin?
For a thicker sauce, chill it for 15-20 minutes—Kewpie mayo naturally thickens when cold. If too thin, whisk in 1 teaspoon water at a time until smooth. For extra creaminess, add ½ teaspoon cornstarch mixed with 1 teaspoon water and stir until thickened.
Can I use jarred capers instead of fresh?
Rinse jarred capers well to remove excess brine, then finely chop them just like fresh. The flavor is identical, and jarred capers last longer in your pantry. Just drain them thoroughly to avoid making the sauce too watery.
What are the best ways to use this sauce?
This versatile sauce works as a burger spread, sandwich topping, or dip for fries and veggies. Try it on grilled chicken, fish tacos, or even as a marinade for 10 minutes before cooking. It also pairs perfectly with Mediterranean dishes like hummus or roasted vegetables.
How long does this sauce keep, and can I freeze it?
Store in an airtight container in the fridge for up to 7 days. For freezing, portion into small containers and freeze for 3 months. Thaw overnight in the fridge—never microwave. The texture may separate slightly after freezing, so stir well before using.
