My Experience Making This Recipe
I first made this sauce on a whim during a burger craving that hit hard on a Tuesday night. Within minutes of mixing, I was dipping fries into it and grinning like an idiot because it tasted exactly like I remembered.
My family couldn’t tell the difference between this and the real deal when I did a side by side comparison at our next cookout. The tangy sweetness balanced against the creamy mayo base hit all the right notes, and the dill pickle relish added that essential bite.
I’ve been making double batches ever since because it disappears terrifyingly fast. One spoonful on a burger, and suddenly everyone at the table wants their own jar.

Ingredients for In N Out Sauce Recipe
- Mayonnaise: 1/2 cup (use full fat for best flavor)
- Ketchup: 3 tablespoons
- Sweet pickle relish: 2 tablespoons (dill pickle relish works too)
- White vinegar: 1 teaspoon
- Granulated sugar: 1/2 teaspoon
Ingredient Notes and Substitutions
- Mayonnaise: This creates the creamy base and carries all the other flavors smoothly. You can use light mayo, but the sauce will be thinner and less rich.
- Ketchup: It adds sweetness, acidity, and that signature pink color to the sauce. Tomato paste thinned with a bit of water and extra sugar can substitute in a pinch.
- Sweet pickle relish: This provides texture and tangy sweetness that makes the sauce pop. Dill relish works fine but will make the sauce slightly more savory and less sweet.
- White vinegar: It brightens the flavors and cuts through the richness of the mayo. Apple cider vinegar or lemon juice can replace it with a slightly different tang.
- Granulated sugar: A touch of sugar balances the acidity and rounds out the flavor profile. Honey or maple syrup can work but will add their own distinct flavors.
How to Make In N Out Sauce Recipe
Step 1: Gather Your Ingredients
Pull all your ingredients from the fridge and pantry so everything is within reach. Having everything ready makes the mixing process smooth and prevents you from hunting for items with mayo covered fingers.
Step 2: Combine the Mayo and Ketchup
Add the mayonnaise and ketchup to your mixing bowl and whisk them together until completely blended with no streaks. This base creates that signature pink color and establishes the creamy texture.
Step 3: Add the Pickle Relish
Stir in the sweet pickle relish, making sure it distributes evenly throughout the sauce. The relish bits should be suspended throughout rather than clumping together, which happens when you mix thoroughly.
Step 4: Mix in the Vinegar
Pour in the white vinegar and stir well to incorporate it completely into the sauce. The vinegar thins the sauce slightly and adds that bright, tangy note that keeps it from tasting flat.
Step 5: Add the Sugar
Sprinkle in the granulated sugar and whisk until it dissolves completely into the mixture. The sugar balances the acidity and creates that subtle sweetness that makes you want another bite.
Step 6: Taste and Adjust
Dip a clean spoon in and taste your sauce, then adjust seasoning as needed. If it’s too tangy, add a pinch more sugar; if too sweet, add a few drops of vinegar.
Step 7: Let the Flavors Meld
Cover the bowl and refrigerate the sauce for at least 15 minutes before serving if you have time. This resting period lets the flavors marry together and develop that authentic taste.
Step 8: Transfer and Store
Spoon the finished sauce into an airtight container or jar for storage. The sauce will keep in the refrigerator for up to two weeks, though it rarely lasts that long in my house.
Pro Tip: Make this sauce at least 30 minutes before you need it if possible. The flavors deepen and blend together beautifully with a little time in the fridge, transforming from good to spot on authentic.
Tips for the Best In N Out Sauce Recipe
- Use high quality mayonnaise because it makes up most of the sauce and cheap brands can taste overly tangy or artificial. The difference is noticeable.
- Drain excess liquid from your pickle relish before adding it to prevent the sauce from becoming too thin and watery. A quick squeeze in your palm does the trick.
- Whisk vigorously to create a completely smooth, homogeneous mixture without any mayo lumps or ketchup streaks. A uniform texture is key to nailing that professional condiment feel.
- Start with the listed sugar amount, then adjust upward based on your preference and the sweetness of your ketchup. Different ketchup brands vary significantly in sugar content.
- Make a double or triple batch because this sauce disappears fast and keeps well refrigerated. You’ll thank yourself when you have extra on hand for impromptu burger nights.
- Let the sauce come to room temperature for about 10 minutes before serving for the best flavor and spreadability. Cold sauce straight from the fridge can be stiff and muted.
Common Mistakes to Avoid
- Using miracle whip instead of mayonnaise creates a tangier, sweeter sauce that tastes noticeably different from the original. Stick with real mayo.
- Adding too much relish makes the sauce chunky and wet instead of creamy and smooth. Measure carefully rather than eyeballing it.
- Skipping the sugar leaves the sauce too acidic and one dimensional without that balanced sweet and tangy profile. Even that tiny amount makes a big difference.
- Not mixing thoroughly enough leaves pockets of straight mayo or ketchup that taste off when you hit them. Whisk until completely uniform.
- Serving the sauce immediately without any rest time means the flavors taste separate rather than blended. Even 15 minutes helps tremendously.
Serving Suggestions
This sauce belongs on burgers first and foremost, but it’s shockingly versatile beyond that. I’ve found myself putting it on things I never expected because the flavor just works.
- Spread generously on beef burgers, turkey burgers, or veggie burgers for that authentic West Coast experience
- Use as a dipping sauce for french fries, sweet potato fries, or onion rings
- Slather on grilled chicken sandwiches or crispy chicken tenders for a tangy kick
- Mix into potato salad or coleslaw as a flavor packed dressing
- Serve alongside fish tacos or fried fish for a creamy, tangy contrast
Variations to Try
- Spicy version: Add 1/2 teaspoon of hot sauce or a pinch of cayenne pepper for heat that plays nicely with the sweetness. The spice cuts through the richness beautifully.
- Garlic lover’s twist: Stir in 1/4 teaspoon of garlic powder or 1 small minced garlic clove for a savory depth. This makes it taste more like a special aioli.
- Smoky BBQ style: Mix in 1/2 teaspoon of smoked paprika for a subtle smoky note that works great on grilled meats. The smokiness adds complexity without overwhelming.
- Extra tangy: Double the vinegar and add a teaspoon of lemon juice for a brighter, more acidic sauce. This version cuts through fatty foods exceptionally well.
- Dill pickle version: Replace sweet relish with dill relish and add 1/4 teaspoon dried dill for a more herbaceous, less sweet profile. This tastes closer to traditional burger sauce.
Dietary Adaptations
- Gluten free: This recipe is naturally gluten free as long as you check that your ketchup and relish don’t contain any sneaky gluten containing additives. Most major brands are safe.
- Dairy free: The recipe is already dairy free since it uses mayonnaise instead of dairy based ingredients. Just verify your mayo brand doesn’t contain any milk derivatives.
- Vegan: Swap regular mayo for vegan mayonnaise made from aquafaba or soy to keep the same creamy texture. The flavor stays remarkably close to the original.
- Low carb or keto: Replace the ketchup with sugar free ketchup and omit the granulated sugar to drop the carbs significantly. The sauce will be less sweet but still delicious.
Storage and Reheating
Refrigerator
Store the sauce in an airtight container in the refrigerator where it will keep fresh for up to 2 weeks. Always use a clean spoon when scooping to prevent contamination.
- Press plastic wrap directly onto the surface before sealing to prevent a skin from forming
- Label the container with the date so you know when you made it
- Keep it in the main body of the fridge rather than the door for consistent temperature
Freezer
I don’t recommend freezing this sauce because mayonnaise based condiments separate and become grainy when thawed. The texture completely changes and becomes unappetizing.
- If you must freeze it, use within 1 month and whisk vigorously after thawing
- Expect a slightly different consistency that may work for mixing into dishes but not for spreading
Reheating
This sauce is meant to be served cold or at room temperature, never heated. Warming it can cause the mayo to separate and develop an off putting texture and flavor.
- Remove from the fridge 10 minutes before serving for optimal spreadability
- Stir before using if any separation has occurred during storage

Frequently Asked Questions
Can I use dill pickle relish instead of sweet pickle relish?
Yes, dill pickle relish works perfectly fine and creates a slightly more savory, less sweet sauce. The flavor will be different but still delicious, leaning more toward traditional burger sauce territory.
How far in advance can I make this sauce?
You can make it up to 2 weeks ahead and store it in the refrigerator in an airtight container. The flavors actually improve after a day or two as everything melds together.
Why is my sauce too runny?
Excess liquid from the pickle relish is the usual culprit, so drain it well before adding. You can thicken runny sauce by whisking in an extra tablespoon of mayo.
Can I make this without sugar?
You can omit the sugar, but the sauce will taste more acidic and less balanced. A sugar substitute like stevia or erythritol works if you’re avoiding regular sugar for dietary reasons.
Does this taste exactly like the real In N Out spread?
It tastes remarkably close and most people can’t tell the difference in a blind test. The flavor profile hits all the same notes of creamy, tangy, and slightly sweet that make the original so addictive.
