Ingredients You’ll Need

The beauty of this In-N-Out Sauce (Copycat Recipe) Recipe lies in its simplicity—just a handful of staple ingredients come together to build its signature flavor, texture, and appearance. Each one plays a crucial role: from the creaminess of the mayo to the slight tang of the vinegar, and the sweet crunch of the relish.

• Mayonnaise: Provides the rich, creamy base that makes the sauce irresistibly smooth.
• Ketchup: Adds a subtle sweetness and the classic tomato tang that balances the mayo.
• Sweet pickle relish (chopped extra fine): Introduces a sweet crunch with bursts of tang, enhancing the sauce’s texture.
• White vinegar: Offers a touch of acidity that brightens up the sauce and prevents it from feeling too heavy.
• Pinch kosher salt: Helps to heighten all the flavors, ensuring nothing tastes flat or shy.

How to Make In-N-Out Sauce (Copycat Recipe) Recipe

Step 1: Combine the Ingredients

This sauce is all about the perfect blend. In a small mixing bowl, add the mayonnaise, ketchup, sweet pickle relish, white vinegar, and a pinch of kosher salt. The key is to ensure the relish is finely chopped so it integrates smoothly without overwhelming the sauce.

Step 2: Stir Thoroughly

Use a spoon or small whisk to mix everything together until the texture is fully uniform. You want a creamy, slightly chunky sauce where every flavor is balanced and no single ingredient dominates.

Step 3: Chill and Let Flavors Develop

While you can use the sauce immediately, letting it chill in the refrigerator for a few hours really helps the flavors marry, making every bite even more delicious. It’s a simple step that results in a spectacular dip or spread.

How to Serve In-N-Out Sauce (Copycat Recipe) Recipe

Garnishes

This sauce works beautifully with simple garnishes like a sprinkle of freshly ground black pepper or a few finely chopped fresh chives or parsley. They add a little burst of color and an extra layer of freshness that complements the tangy sauce.

Side Dishes

Think beyond burgers—this sauce shines next to crispy fries, onion rings, chicken tenders, or even as a creamy dip for fresh veggie sticks. Its versatility makes it a must-have condiment that transforms any snack into a crave-worthy treat.

Creative Ways to Present

Try it spooned over a burger patty with fresh lettuce and tomato, swirled into a wrap, or even dolloped on a hot dog for a fusion twist. You can also serve it in a small ramekin at your next party, letting guests dip and drizzle to their heart’s delight.

Make Ahead and Storage

Storing Leftovers

If you have any leftover sauce (although that’s unlikely!), store it in an airtight container in the refrigerator. It will keep beautifully for up to a week, and the flavors may even deepen over time for an even tastier experience.

Freezing

Because this sauce contains mayonnaise and relish, freezing isn’t recommended. The texture and flavor can suffer once thawed, so it’s best enjoyed fresh or refrigerated.

Reheating

This sauce tastes best cold or at room temperature, so avoid reheating. Simply take it out of the fridge and let it sit for a few minutes before serving to soften the chill and bring out the full flavor.

FAQs

Can I use regular pickle relish instead of sweet pickle relish?

Yes, but it will change the flavor profile slightly. Sweet pickle relish adds a touch of sweetness that balances the tang and creaminess. Using regular relish may make the sauce more tart, so you might want to add a small pinch of sugar to maintain balance.

Is this sauce spicy?

No, this In-N-Out Sauce (Copycat Recipe) Recipe is not spicy. It’s designed to be tangy, sweet, and creamy; however, feel free to add a dash of hot sauce or cayenne pepper if you like a bit of heat.

Can I make this sauce vegan or dairy-free?

Absolutely! Swap the mayonnaise for a vegan mayo, and ensure your ketchup and relish don’t contain animal-derived ingredients. The flavor will still be delicious and just as satisfying.

How thick should the sauce be?

The sauce should be thick enough to stick to burgers and fries without running off, but smooth enough to spread easily. If it seems too thick, add a few drops of water or vinegar to thin it slightly.

Can I double or triple this recipe for a party?

Yes, this sauce scales beautifully. Just multiply the ingredients and mix thoroughly. It’s a fantastic crowd-pleaser that will disappear quickly at any gathering.
