My Experience Making This Recipe
I first made this spread on a whim after watching videos of In-N-Out employees preparing burgers. I mixed the ingredients together and spread it on a simple cheeseburger, then waited for disappointment that never came.
The first bite took me straight to a California In-N-Out booth, and my burger-loving guests couldn’t believe I’d made it at home. Since then, I’ve kept a jar in my fridge permanently, using it on everything from weekend cookouts to quick weeknight dinners.
What surprised me most was how the flavors meld together overnight, becoming even more developed and nuanced. The spread has become my secret weapon for elevating any burger situation.

Ingredients for In-N-Out Spread
- 1 cup mayonnaise
- 2 tablespoons ketchup
- 1 tablespoon yellow mustard
- 1 teaspoon pickle relish
- 1/4 teaspoon garlic powder
- 1/4 teaspoon paprika
- Pinch of black pepper
- Pinch of cayenne pepper (optional, for subtle heat)
Ingredient Notes and Substitutions
- Mayonnaise: This is your base and creates the creamy texture that makes the spread cling to your burger. If you want a lighter version, swap half the mayo for Greek yogurt, though you’ll lose some richness.
- Ketchup: Adds sweetness and umami depth that balances the mayo. Tomato paste mixed with a tiny bit of honey works in a pinch, but regular ketchup is your best bet.
- Yellow Mustard: Provides the tangy backbone that makes this spread taste familiar. Brown or Dijon mustard will shift the flavor profile noticeably, so stick with yellow.
- Pickle Relish: Contributes a subtle briny texture and flavor complexity. If you only have whole pickles, finely mince them and use about 1 teaspoon, draining excess liquid.
- Garlic Powder: Delivers savory depth without the harshness of fresh garlic. Fresh minced garlic will make the spread watery and overpower the other flavors.
How to Make In-N-Out Spread
Step 1: Gather Your Ingredients
Set out all your ingredients so you can work quickly and see exactly what you’re adding. Having everything ready prevents mistakes and keeps the process smooth.
Step 2: Add Mayonnaise to Your Bowl
Pour the full cup of mayonnaise into your mixing bowl, creating a blank canvas for your other flavors. This generous base ensures you’ll have enough spread to coat multiple burgers without running short.
Step 3: Mix in the Ketchup
Add the ketchup and stir it into the mayo using a whisk or fork until no streaks of red remain. This step builds the sweetness and color that make the spread visually appealing and flavorful.
Step 4: Add the Yellow Mustard
Stir in the yellow mustard, whisking thoroughly to incorporate it evenly throughout the mixture. The mustard is what gives this spread its signature tangy edge that keeps you coming back for more bites.
Step 5: Incorporate the Pickle Relish
Add the pickle relish and mix well, making sure those little pickle pieces distribute evenly. The relish adds a subtle textural element and briny note that makes the spread feel more complex and interesting.
Step 6: Season with Garlic Powder and Paprika
Sprinkle in the garlic powder and paprika, whisking to combine everything thoroughly. These spices add savory depth and a hint of warmth that rounds out all the other flavors.
Step 7: Add Black Pepper and Optional Cayenne
Finish with a pinch of black pepper and cayenne if you want a gentle heat component. Taste the spread now and adjust any seasonings if needed, adding a touch more mustard or garlic powder if it feels too mayo-forward.
Step 8: Transfer to Your Storage Container
Use a rubber spatula to scrape every bit of spread into a glass jar or airtight container. Store it in the refrigerator where it will keep for up to two weeks, getting even more flavorful as it sits.
Pro Tip: Let your spread sit in the fridge for at least two hours before using it so the flavors have time to marry and develop, making it taste even closer to the restaurant version.
Tips for the Best In-N-Out Spread
- Use high-quality mayonnaise like Duke’s or Hellmann’s, as cheaper versions can taste off and affect your final product. The mayo carries most of the spread, so this matters more than you’d think.
- Don’t skip the two-hour rest period if you have time, as the flavors develop noticeably in the fridge. This makes a real difference between “pretty good” and “how did you do this.”
- Keep the spread at room temperature for fifteen minutes before serving if it’s been in the fridge, which makes it spread more easily on burgers without tearing the buns. Cold spread can be stubborn and create frustrating situations.
- Make a double batch and store it in a clean glass jar with a tight lid, treating it like you would store-bought condiments. You’ll thank yourself later when you have it ready for impromptu burger nights.
- Taste as you go and adjust seasonings to your preference, adding more mustard for tang or more ketchup for sweetness. Everyone’s palate is different, so customizing to your liking makes sense.
Common Mistakes to Avoid
- Using too much garlic powder or adding fresh garlic will overpower the other flavors and make the spread taste aggressively garlicky. The garlic should be a whisper, not a shout.
- Skipping the paprika might seem minor, but this spice adds color and a subtle warmth that makes the spread taste more authentic. Without it, the spread tastes flatter and less restaurant-quality.
- Using wet pickles or relish that hasn’t been drained will add excess moisture and make your spread runny. Squeeze out liquid before measuring if you’re using fresh pickles.
- Storing the spread in a container that allows air exposure will cause it to oxidize and darken, affecting both flavor and appearance. Always use airtight containers.
Serving Suggestions
This spread shines on burgers, but it earns its place on way more than that. Think of it as your new favorite condiment for anything that needs a creamy, tangy boost.
- Classic cheeseburgers topped with pickles, onions, and lettuce for the full In-N-Out experience
- Grilled chicken sandwiches with tomato and fresh arugula
- Hot dogs with caramelized onions and mustard for a gourmet twist
- French fries for dunking, which hits different when you try it
- Crispy fish sandwiches with tartar sauce and coleslaw
Variations to Try
- Spicy Version: Add 1/2 teaspoon of sriracha or hot sauce to kick up the heat without changing the core flavor profile. This works beautifully on spicy chicken or beef burgers.
- Herb-Infused Spread: Mix in 1 teaspoon of finely minced fresh dill or chives for a brighter, fresher take. This variation pairs wonderfully with fish or turkey burgers.
- Smoky Spread: Add 1/4 teaspoon of smoked paprika instead of regular paprika for a deeper, smokier flavor. This version elevates burgers with bacon and cheddar.
- Lighter Version: Replace half the mayo with Greek yogurt or sour cream for fewer calories without sacrificing creaminess. You lose a tiny bit of richness, but gain a tangier profile.
- Truffle Spread: Stir in 1/2 teaspoon of black truffle oil for an upscale burger spread that still tastes familiar. This turns a casual burger into something special.
Dietary Adaptations
- Gluten-Free: All standard ingredients are naturally gluten-free, though check your ketchup and relish labels to confirm no gluten-containing additives are present. Most major brands are safe, but some specialty varieties might contain gluten.
- Dairy-Free: Swap the mayo for a dairy-free version like Hellmann’s dairy-free mayo or cashew-based mayo for a plant-forward spread. The flavor will be slightly lighter, but the spread still works beautifully.
- Vegan: Use vegan mayonnaise and confirm your ketchup and relish contain no animal products, which most do. This spread becomes completely vegan-friendly with minimal adjustments.
- Low-Carb and Keto: This spread is already low in carbs since mayo forms the base, making it ideal for keto diets. Just watch out for carbs in ketchup by using a sugar-free version if you’re strict about carb counts.
Storage and Reheating
Refrigerator
Store your spread in an airtight glass jar on a shelf rather than the door, where temperature fluctuations happen. Properly stored, it keeps for up to two weeks and actually improves as flavors develop.
- Use a clean spoon every time you scoop to prevent contamination
- Keep the lid tightly sealed between uses
- Discard if you notice any off smells or mold growth
Freezer
Freezing works, though mayo-based spreads can separate slightly when thawed, requiring a quick stir to bring back the texture. Most people find the two-week fridge life sufficient.
- Freeze in ice cube trays for portioned servings if you want to extend storage
- Thaw in the refrigerator overnight before using
- Stir well after thawing to recombine any separated ingredients
Reheating
This spread doesn’t need reheating since it’s meant to be served cold or at room temperature. Simply let it sit out for fifteen minutes before using if it’s been chilled.
- Never microwave the spread, as heat breaks down mayo and creates an unpleasant texture
- Use it straight from the fridge if you prefer a firmer consistency

Frequently Asked Questions
Can I make this spread without mayonnaise?
Mayo is really the foundation, but you can experiment with Greek yogurt or sour cream for a lighter version. The flavor will shift noticeably, and the texture won’t be quite as creamy, so mayo is honestly the best choice.
How long does this spread keep in the refrigerator?
Stored properly in an airtight container, it keeps for up to two weeks with no issues. After two weeks, discard it and make a fresh batch since mayo-based products can develop off-flavors over time.
Can I make this spread ahead of time for a cookout?
Absolutely, and in fact making it a day or two ahead allows the flavors to blend and develop even more. Just store it in an airtight container in the fridge until you’re ready to use it.
Why does my spread taste too mayonnaise-forward?
This usually means you need more of the tangy and savory elements like mustard, garlic powder, and paprika. Add these ingredients a pinch at a time while tasting until you reach the balance you prefer.
Is this really the same as In-N-Out’s spread?
It’s remarkably close based on reverse-engineering videos and taste comparisons, though the chain’s exact formula remains a trade secret. Most people can’t tell the difference once it’s on a burger, which is what matters.
Can I use this spread on things other than burgers?
Definitely, and this is where the spread shows its versatility and value. Try it on fries, chicken sandwiches, hot dogs, fish tacos, or even as a dip for vegetables.
