Step‑by‑Step Instructions for Copycat In-N-Out Sauce
Step 1: Combine Ingredients
In a medium mixing bowl, add 1 cup of mayonnaise, 2 tablespoons of ketchup, 1 tablespoon of yellow mustard, 1 teaspoon of white vinegar, and 2 tablespoons of sweet pickle relish.

Copycat In-N-Out Sauce Recipe FAQs
How do I select the best mayonnaise for this sauce?
Absolutely! Look for a mayonnaise that is creamy and rich—real mayonnaise works best. If you’re aiming for a lighter option, Greek yogurt is an excellent substitute, which also adds a tangy flavor. Just ensure it’s a plain variety to maintain the intended taste.
Can I store leftover Copycat In-N-Out Sauce, and for how long?
Very! You can store your sauce in an airtight container in the refrigerator for up to 2 weeks. It will not only stay fresh but also allow the flavors to deepen. Make sure to give it a good stir before using, as some separation may occur.
Is freezing the sauce a good idea?
While I don’t usually recommend freezing because it may alter the texture, you can freeze it in a tightly sealed container for up to 3 months. To thaw, simply transfer the sauce to your fridge overnight and stir well before serving to regain some of that creamy consistency.
What should I do if my sauce is too runny?
If your Copycat In-N-Out Sauce turns out too runny, try adding more mayonnaise a tablespoon at a time until you achieve your desired thickness. Alternatively, you can mix in a little extra ketchup or even a bit of cornstarch mixed with water (just be sure to simmer it to activate the thickening process before adding it in).
Are there any dietary considerations I should be aware of?
Definitely! This sauce contains common allergens including eggs (from the mayonnaise) and possibly gluten (if using traditional ketchup). If you’re cooking for someone with dietary restrictions, opt for vegan mayo and gluten-free ketchup to ensure everyone can enjoy this delicious Copycat In-N-Out Sauce!
