How to make In-N-Out sauce
Measure out the ingredients. Also, if you think you will need a big batch, you can easily double the recipe.
Place all the ingredients in a bowl (or directly in a jar or glass container) and stir until well incorporated. Now, you can taste test and adjust to your liking—you can add a pinch of salt, pepper, paprika, or yellow mustard if wanted.
Then, transfer the mixture to a jar or glass container. Finally, let it rest for the best flavor—place it in the fridge for 30-60 minutes before serving to allow the flavors to meld.
How to serve In-N-Out sauce
This In-N-Out burger spread is such a versatile topping. Here are some of my favorite ways to use it:
- As a burger sauce: Spread a generous amount to the burger buns before adding the grilled burger patties and your toppings. And don’t forget the grilled onions.
- Dip for potatoes: Use this creamy dip for these easy air fryer french fries or baked french fries.
- Dip for veggies: You can also dip fresh veggies cut into sticks—this makes such a yummy appetizer.
- For chicken: Serve with crispy fried chicken breast or air fryer chicken tenders.
- For meat: Drizzle or brush the In-N-Out sauce over grilled meats for extra flavor.
- As a spread: Whenever you want a quick lunch or a snack, use the sauce on sandwiches, lettuce wraps, or hot dogs.
How to store
- In the fridge: You can store the sauce in an airtight container in the refrigerator for up to 2 weeks.
- Make ahead: The In-N-Out sauce is even better after the flavors have had time to meld. So you can prepare it a day or two before you need it and you can keep it in the fridge.
