Ingredients for In-N-Out Sauce Recipe

• 1 cup mayonnaise
• 2 tablespoons ketchup
• 1 tablespoon white vinegar
• 1 tablespoon pickle relish
• 1/2 teaspoon garlic powder
• 1/4 teaspoon paprika
• 1/4 teaspoon black pepper
• Pinch of salt to taste

Ingredient Notes and Substitutions

• Mayonnaise forms the creamy base and carries all the other flavors. Use full-fat mayo for the best richness, though you can swap it with Greek yogurt for a tangier, lighter version.
• Ketchup adds sweetness and tomato depth. If you only have tomato paste, use one teaspoon diluted with water, though the flavor will be more concentrated.
• White vinegar provides the signature tang. Apple cider vinegar works as a substitute but will give you a slightly sweeter edge.
• Pickle relish brings pickled complexity and texture. Finely minced dill pickle can replace it if you have no relish on hand, though you’ll lose some of the sweet-sour balance.
• Garlic powder delivers savory depth without raw bite. Fresh minced garlic will make the sauce grainier and won’t blend as smoothly.

How to Make In-N-Out Sauce Recipe

Step 1: Gather Your Ingredients

Pull out all five core ingredients and your small mixing bowl. Having everything prepped and visible prevents you from forgetting a component and ensures consistent results every batch.

Step 2: Add Mayonnaise to the Bowl

Measure out one cup of mayonnaise into your mixing bowl. This creamy base will hold all the other flavors together and create that signature richness.

Step 3: Mix in the Ketchup

Add two tablespoons of ketchup to the mayo and stir well. The ketchup dissolves into the mayo and creates that subtle tomato sweetness that makes people wonder what’s in your sauce.

Step 4: Add the Vinegar

Pour in one tablespoon of white vinegar and mix thoroughly. Vinegar cuts through the richness and adds that characteristic tangy note that makes this sauce pop on a burger.

Step 5: Incorporate the Pickle Relish

Stir in one tablespoon of pickle relish until fully combined. The relish brings a subtle sweetness and briny complexity that rounds out the whole flavor profile perfectly.

Step 6: Add Garlic Powder

Sprinkle in one-half teaspoon of garlic powder and mix well. Garlic powder dissolves smoothly into the mayo and adds savory depth without any graininess.

Step 7: Season with Paprika and Black Pepper

Add one-quarter teaspoon each of paprika and black pepper. Paprika gives a hint of smokiness while black pepper adds a gentle bite that lingers on your palate.

Step 8: Taste and Adjust

Taste a small spoonful and add a pinch of salt if needed. Most people don’t need additional salt since mayo and relish already contain it, but every batch varies slightly based on your ingredients.

Step 9: Transfer and Store

Spoon the sauce into a glass jar with a tight-fitting lid. Transfer it to the fridge immediately where it will keep fresh and ready to use.

Pro Tip: Make a double batch and store it in a squeeze bottle for easy application on burgers, fries, and sandwiches.

Tips for the Best In-N-Out Sauce Recipe

• Use fresh mayo that hasn’t been sitting in your cabinet for a year. Fresher mayo tastes creamier and prevents any off-flavors from affecting your sauce.
• Whisk the ingredients instead of just stirring to incorporate air and create a smoother texture. A light whisk takes only 30 seconds and makes a noticeable difference.
• Let the sauce sit in the fridge for at least two hours before serving. The flavors meld and deepen significantly once they’ve had time to marry together.
• Taste before adding extra salt since mayo and relish already contain sodium. You’ll likely find it needs no additional salt at all.
• Make this sauce the morning of your cookout rather than the night before. While it keeps for two weeks, the fresher it is, the brighter the flavors taste.
• Keep the proportions exact the first time you make it. Once you nail this version, you can experiment with extra garlic, more vinegar, or spicy additions.

Common Mistakes to Avoid

• Using low-fat or light mayo ruins the creamy base that makes this sauce special. Cheap mayo also throws off the flavor balance, so splurge a bit on quality here.
• Adding fresh garlic instead of garlic powder creates a grainy, separated texture. Powder dissolves smoothly while fresh garlic clumps and doesn’t blend evenly.
• Forgetting the pickle relish eliminates the sweet-briny complexity that makes people ask for your recipe. Don’t skip it or substitute it without testing first.
• Over-whisking or using a blender turns the sauce slightly broken and too thin. Gentle stirring keeps it thick and spreadable.
• Not chilling the sauce long enough means the flavors taste flat and separated. Two hours minimum in the fridge transforms the taste dramatically.

Serving Suggestions

This sauce deserves more than just burgers, though it absolutely shines there. Spread it on anything from grilled meats to roasted vegetables for an instant flavor boost.

• Swirl it into a cocktail sauce recipe for a gourmet shrimp dip
• Dollop it on grilled chicken breasts or fish fillets
• Mix it with mayo for a special sandwich spread that changes everything
• Use it as a fry dipping sauce instead of ketchup alone
• Spread it inside tacos or wraps for a unexpected kick

Variations to Try

• Spicy Version: Add one-quarter teaspoon of cayenne pepper and one-half teaspoon of hot sauce for a sauce that bites back. This works perfectly for those who love heat.
• Smoky Variation: Increase paprika to one-half teaspoon and add one-quarter teaspoon of smoked paprika for deeper complexity. This version pairs beautifully with grilled meats.
• Herb-Forward Sauce: Stir in one tablespoon of fresh minced dill or parsley for brightness and freshness. This lighter version works great with fish and seafood.
• Southwestern Style: Replace pickle relish with diced jalapeños and add one-quarter teaspoon of cumin. This variation brings a Mexican-inspired twist to burgers and sandwiches.
• Tangy Boost: Add an extra half tablespoon of vinegar for maximum tang. This version is perfect for those who love aggressive acidity and bright flavors.

Dietary Adaptations

• Gluten-Free: All core ingredients are naturally gluten-free, though verify your mayo and ketchup labels for hidden gluten. Most major brands are safe, but always check.
• Dairy-Free: This sauce contains no dairy and is already vegan-friendly, making it perfect for anyone with restrictions. The mayo provides all the creamy richness you need.
• Vegan: Substitute traditional mayo with vegan mayo in equal amount and the sauce remains completely plant-based. The flavor difference is minimal with quality vegan mayo.
• Low-Carb/Keto: This sauce is already quite low in carbs at roughly two grams per two-tablespoon serving. Use it liberally on keto burgers without worry.

Frequently Asked Questions

Can I double or triple this recipe?

Yes, the recipe scales up perfectly for larger batches. Keep the ingredient proportions exact and store in multiple containers for best results.

Why is my sauce separating?

Separation happens when the sauce gets too warm or sits too long after mixing. Stir it well and return it to the fridge to fix this issue.

What’s the difference between this and seafood boil sauce recipe?

This sauce is mayo-based and tangy while seafood boil sauce typically uses butter and spices. They serve different purposes, but both are excellent condiments.
