Ingredients for in n out burger sauce copycat
Five simple ingredients transform into the iconic sauce that makes burgers legendary.
| Ingredient | Amount | Notes |
|---|---|---|
| Mayonnaise 🥛 | ¾ cup | High-quality, smooth texture |
| Yellow Mustard 🍯 | ½ cup | Dijon preferred for depth |
| Dill Pickle Chips 🥒 | ¼ cup | Finely chopped, not juice |
| Granulated Sugar 🍚 | 1 ½ tbsp | Balances tanginess |
| White Vinegar 💧 | 1 tbsp | Adjust for tang preference |
| Kosher Salt 🧂 | ½ tsp | Enhances umami |
The mayonnaise is non-negotiable here—Hellmann's or Duke's are my go-tos for that smooth, rich base. Yellow mustard? French's Dijon adds that signature depth, but regular yellow works too. For the pickles, dill chips from a jar (not fresh pickles) give you that perfect grainy texture. I always grab the Heinz or Vlasic dill chips from the store—they're consistent and cheap. The sugar and vinegar are about balance: start with the amounts listed, then tweak to taste. Too tangy? Add more sugar. Too sweet? A splash of vinegar fixes it.
No Dijon mustard? Regular yellow mustard works fine, though the flavor will be slightly milder. Pickle chips too expensive? Finely chopped bread-and-butter pickles in a pinch, but they'll change the texture slightly. Want extra tang? Add 1/2 teaspoon of pickle juice to the mix. The salt is crucial—Diamond Crystal is my preference, but any kosher salt works. Pro tip: Let the sauce sit for 10 minutes before tasting—flavors meld better that way. And trust me, the texture is everything: creamy but with just enough graininess to mimic the real deal.
This sauce keeps beautifully—1 week in the fridge sealed in a jar. The flavor actually improves after a day or two, so make extra. For leftovers, give it a quick stir before using. Freezes well for up to 3 months if you want to prep ahead. I always make a double batch: one for burgers, one for fries. The secret? Don't skip the salt—it's what ties everything together.
Why You'll Love This Recipe
- Here’s what sold me: I make a big batch on Sunday, and it’s still fresh by Friday. The vinegar and sugar act like preservatives, so it doesn’t go bad fast. Plus, it’s cheap—you’re not spending a fortune on specialty ingredients, just pantry staples. Win-win.
- Five-Ingredient Magic: Honestly, I’ve made sauces with way more ingredients that still didn’t taste as good. This one? Just mayo, mustard, crushed pickles, sugar, and vinegar—no fuss, no stress. The pickles add that signature tang without overpowering, and the sugar balances it just right.
- Tangy, Sweet, Addictive: Between us, that first bite of a burger drizzled with this sauce is chef’s kiss. The vinegar cuts through the richness, the sugar keeps it from being too sharp, and the pickles? They’re the secret—crushed just enough to dissolve into that creamy, slightly grainy texture that’s impossible to resist.
- Picnic to Potluck: I’ve used this sauce on everything from burgers to hot dogs, even as a dip for fries at a backyard BBQ. It’s the kind of thing that makes you the star of any spread—no matter how casual. (Yes, even on a Tuesday night when you’re just grilling in your backyard.)
Step-by-step instructions for in n out burger sauce copycat recipe
Here's how to recreate that iconic tangy, slightly sweet sauce that makes every In N Out burger unforgettable.
Combine Wet Ingredients for a Smooth Base
In a medium bowl, whisk together the 0.75 cup mayonnaise and 0.5 cup yellow mustard until fully blended. I like to use a fork for this step—it gives you more control than a whisk and ensures no lumps remain. The mayonnaise should be at room temperature for the best texture, so take it out of the fridge about 10 minutes before starting.
Next, add the 1 tbsp white vinegar and 1.5 tbsp granulated sugar. The vinegar adds that signature tang, while the sugar balances the sharpness. Mix well until the sugar dissolves completely—you should see a smooth, slightly thickened mixture. If you're using Dijon mustard, you'll notice a deeper flavor right away, which is key to replicating that restaurant taste.
Fold in Pickle Chips for Texture and Flavor
Now comes the secret ingredient: the 0.25 cup dill pickle chips. I don't recommend using pickle juice here—it's too watery and won't give you that perfect chunky texture. Instead, pulse the chips in a food processor until they're finely chopped but still have some texture. This ensures each bite delivers that classic In N Out pickle punch.
Gently fold the chopped pickle chips into the wet mixture using a rubber spatula. Be careful not to overmix—you want the chips distributed evenly but still visible. The sauce should have a thick, spreadable consistency, similar to the original. If it looks too thick, add a teaspoon of water to loosen it slightly. Taste as you go—this is where you can adjust the balance of sweet, tangy, and salty.
Season to Perfection and Let It Rest
Add the 0.5 tsp kosher salt and mix thoroughly. This step is crucial—don't skip it. The salt enhances all the flavors and ties everything together. Taste the sauce again and adjust if needed. Some people prefer it sweeter, others like it more tangy. I usually add a tiny bit more sugar or vinegar at this stage to get it just right.
Once seasoned to your liking, transfer the sauce to an airtight container and refrigerate for at least 30 minutes. This resting period allows the flavors to meld together. I've found that making it ahead of time actually improves the taste—it gives the vinegar and mustard time to mellow out. When you're ready to serve, give it a quick stir before using. The sauce should be thick enough to cling to fries or burgers without dripping, but still spreadable.
Use Immediately for Best Results
This sauce is best used fresh from the fridge. Spread it generously on your In N Out-style burgers, fries, or even as a dip for onion rings. The texture should be smooth with just a hint of pickle texture in each bite. If you notice the sauce separating after a few days, just give it a good stir—it'll come back together.
For the most authentic experience, serve it immediately after making. The sauce pairs perfectly with crispy fries, juicy burgers, or even as a topping for their famous animal-style fries. Remember, the secret to this copycat recipe isn't just the ingredients—it's the balance. Take your time with the seasoning, and you'll have sauce that rivals the original every time.
Pro Tips For Making In N Out Burger Sauce Copycat
- Pulse the Pickles: Mix in the dill pickle chips one tablespoon at a time while the sauce is still in the bowl—don’t just dump them all at once. This keeps them evenly distributed and prevents clumping, which is how you get that signature speckled texture without extra effort.
- Use Room-Temp Mayo: Take the mayonnaise out of the fridge 30 minutes before mixing—cold mayo thickens the sauce and makes it harder to blend smoothly. I learned this the hard way after making a lumpy batch that tasted like someone had forgotten to stir.
- Measure Vinegar Precisely: Don’t eyeball the white vinegar—use a scale or measuring spoon for the 1 tablespoon. Too little and the sauce tastes flat; too much and it’s harsh. The balance is what makes it tangy but not sour.
- Skip the Sugar Substitute: Granulated sugar is non-negotiable here—powdered or brown sugar changes the texture and flavor. If you’re in a pinch, use honey, but reduce it to ½ tablespoon and mix it in last to avoid altering the sauce’s consistency.
Make-ahead tips for this recipe
Batch Prep Strategy
Make a double batch—this sauce tastes even better after sitting for 24 hours as flavors meld. Store in a glass jar with an airtight lid (I use Ball mason jars) in the fridge.
The texture thickens slightly overnight, making it perfect for dipping or spreading. Label it clearly since it’s addictive—trust me, you’ll go through it fast! 🥫
Freezer-Friendly Tips
For long-term storage, portion into ice cube trays before freezing. Once frozen, transfer cubes to a ziplock bag and flatten to save space. Thaw in the fridge overnight—no microwave needed.
The texture remains creamy when reheated gently on the stovetop with 1 tsp water to loosen. Freeze for up to 3 months without quality loss. 🧊
Portion Control
Use 1-tablespoon portions for burgers and 2 tablespoons for fries. Store in small shot glasses or mini mason jars for easy grab-and-go serving. These portions prevent waste and ensure you never run out mid-meal. I keep a jar in my fridge just for fries—it disappears faster than you’d think! 🍔
Sauce Stability
If the sauce separates after refrigeration, stir in 1 teaspoon of warm water or pickle juice to re-emulsify. Avoid shaking vigorously—this can incorporate air and make the texture grainy.
For extra insurance, add ½ teaspoon of xanthan gum (a stabilizer) when making a large batch. This keeps it smooth for up to 7 days in the fridge. 💧
Make-Ahead Timeline
Plan ahead: Make the sauce 1-2 days before your burger night. The flavors deepen over time, and the texture becomes ideal. Store in the fridge, and bring to room temperature for 10 minutes before serving—this enhances the spreadability.
I always prep mine Sunday afternoon for Monday night feasts. Timing is everything! ⏰
Travel-Friendly Packing
Pack sauce in small, leak-proof containers (I use Stojo squeeze bottles) for picnics or road trips. These fit perfectly in cooler bags and keep the sauce contained.
For extra safety, freeze the sauce in the container, then thaw in the cooler—it stays cold longer. Perfect for In-N-Out-themed BBQs or tailgates! 🚗

Frequently asked questions
Can I make this sauce without mayonnaise?
The mayonnaise is essential for that signature creamy texture, but if you're avoiding it, try substituting with Greek yogurt or vegan mayo in a 1:1 ratio. The sauce will be slightly lighter, but the tangy flavor will still shine. For extra richness, add 1 tablespoon of olive oil to the mix. Just remember, the texture will be less thick and more spreadable.
Why does my sauce taste too tangy?
If your sauce tastes too sharp, it’s likely from the vinegar or mustard. Balance it by adding ½ teaspoon more sugar or a pinch of salt. Let it sit for 10 minutes before tasting again—the flavors will mellow out. For a smoother fix, whisk in 1 teaspoon of honey or maple syrup to soften the acidity.
How do I get the perfect pickle chip texture?
Use dill pickle chips from a jar, not fresh pickles or juice—they’re too watery. Pulse them in a food processor until they’re finely chopped but still slightly chunky. If you don’t have a processor, finely dice them with a knife. The goal is tiny, grainy bits that add texture without overpowering. Avoid over-processing, or the sauce will turn mushy.
Can I use this sauce on other foods besides burgers and fries?
This sauce is versatile—try it on hot dogs, grilled cheese, chicken tenders, or even as a dip for veggies. It also works as a marinade for grilled meats or a dressing for sandwiches. The key is balance: use it sparingly on delicate foods like salads, but don’t hesitate to go bold on heartier dishes.
What’s the best way to store leftovers?
Transfer the sauce to an airtight container and refrigerate for up to 1 week. If it separates, stir in 1 teaspoon of warm water or pickle juice to restore the creamy consistency. For longer storage, freeze in ice cube trays for up to 3 months. Thaw overnight in the fridge—never microwave it directly, or the texture will break.
