Copycat In-N-Out Spread Sauce
California here we come, right back where we started from! In-N-Out Burgers originated in my neck of the woods in 1948, and we did our part to make it famous. We still order up animal style double-double cheeseburgers, fries, and the best shakes around. When we can’t hit the road, we grill our own burgers, make our own buns, and a batch of Copycat In-N-Out Spread Sauce.
We really adore how In-N-Out serves it your way. We have indulged by eating plenty of their signature veggie-heavy, never-frozen, well-balanced, tangy-sauced creations through the years. There are a myriad of ways to order their burgers, fries and shakes.
Here’s where Alison comes in. She fancies In-N-Out Spread Sauce like no other on her double-fried fries! So our Copycat In-N-Out Spread Sauce is just for her. Seriously, the rest of you will love it too!
“I really can’t live without my In-N-Out burgers. Honestly, I can’t. Even when I’m doing the whole no carb thing occasionally, I make an exception for these. They’re too delicious to count.”
Copycat In-N-Out Spread Sauce
Alison pours this amazing sauce on her burgers and fries! I’m just sayin’ there’s no such thing as too much when it comes to In-N-Out’s Spread Sauce!
It’s quite like a thousand island dressing, mayo based and creamy. I have seen recipes with both sweet pickle relish and dill pickle relish. We are a dill family, so I always use this variety, but you have our permission to use which ever you’d like.
In a small mixing bowl mix all the ingredients together with a rubber spatula. Snap on the lid and refrigerate overnight so that the flavors can meld.
Keep any leftovers refrigerated and use within a 2 week period.
- 1 cup mayonnaise
- ⅔ cup ketchup
- 3 Tablespoons dill pickle relish
- ½ teaspoon salt
- ½ teaspoon freshly ground pepper
- 2 teaspoons sugar
- 1 teaspoon white wine vinegar
- 1 teaspoon Worcestershire sauce
- 2 Tablespoons fresh lemon juice
- In a small bowl, combine all of the ingredients together.
- Refrigerate overnight before using.
Got a burger or fry sauce you love enough to share?
Something new to try again. I guess it’s good for burgers and anything grilled, too.
i have a weak spot for new sauces and dips. this ones on my list for sure. 🙂
This looks and sounds amazing, and perfect timing with bbq season coming up. I love a burger and chips now and again, will definitely be writing this recipe down for when I next have people over.
I’ve never been to an In n Out Burger. This sauce looks good though and I should give it a try!
I have never even heard of In n Out Burger but this sauce is somethng I mauy have to try!
Add it to your bucket list and then make some of the sauce yourself!
I’ve never been lucky enough to experience the In-N-Out food but next time I’m in the states I’ll be there!
A vegan version doesn’t look that complicated. I should try 🙂
Definitely try it out and then let us know what you thought of it. It is always good to have alternatives!
I’ll add the sauce not only in my burgers but on anything else lol. The pictures really made me hungry
that burger sounds like just what I need! I will have to try this sauce, I love trying new things, thanks for the share!

Sounds delicious! I’m going to try it for myself. I love IN and Out Burger and make stops there whenever I have a chance!
I have never been to an IN n Out before because I do not live in an area that has one. The good there does look good. This sauce looks great too. Will definitely try it next time we have burgers.
I have never eaten at an In & Out Burger before. Apparently, they do have some locations in Texas, just not near me.
I will always treasure those memories of my mother preparing those biscuits, so lovingly.Your posts bring me those memories.I am sure all your delicacies get consumed by the youngsters in your household.When my wife prepares delicacies, I make it a point that they must not leave the house for the neighbours;)))all of it will be just for my kids..am I feeling stupid?
This looks delicious! I had an In N Out Burger when I was in San Francisco for the first time. I was tired of hearing my West Coast friends rave about it. It was delicious and so cheap! I also like a creamy sauce on fries every once in a while, just like the Belgians do.

Let’s just say I will definitely be making this!!!!! One of my favorite things about the west coast is InNOut!
This looks like something great to try. I love different sauces and not just for burgers, for just about anything grilled.
This made my mouth water! Can;t wait to try and make these with those lovely burgers.
It still makes my mouth water, too, Stefan!
Perfect sauce in additional to the burger buns from your other post. This is going to be delicious!
Oh this is awesome. I’d love to be able to whip up my own spread sauce at any time. I’ll have to try this when we’re planning on grilling!
O-M-G. There are a few foods I could eat every day: plantain, pizza, and BURGERS! These look amazing. I don’t cook, but I’ll get someone to make these for me haha.
Even if you don’t cook you could whip this together and add it to your burger. It will be worth it – I promise!
i have never tried in n out burgers, after reading your post, i wanna try the spread recipe and the burger!:)
It is seriously my favorite meal ever! You will have to get over the U.S. and try it some time!
I can imagine this sauce dipping with nachos and burgers…I am sure it will taste so yum!
oh i love that sauce i will try it on fries it looks like delicious on nachos too
i am a burger lover….
Never been there to eat but have heard great things. The sauce looks tasty!
There are reasons why I avoid burgers… but who says I cannot indulge in one? Looking at the burger photo you have makes me drool. Now imagine your sauce… going with the burger… delicious!
Wow, i bet this sauce would taste good on any sandwich!! Does In and Out have a veggie burger on their menu? I really need to visit that restaurant one day because I hear SOOOO much about it. Thanks for sharing this special sauce recipe. 🙂 🙂
This makes me so sad. Mostly because I have to eat at In-N-Out. It’s cruel to hear so much about it and never experience it lol I will have to save this recipe and create my own.
Now I gotta hope that Whole Foods has mayonnaise on sale – this sounds like it would be a really yummy recipe! and easy to make, too!
This looks delicious! I am going to add this to my weekly mail plan.
So glad you like it, Megan!
Oh no I have never tried in n out burger sauce before but it looks delicious and I really do like a Thousand Island Dressing.
Ana, It is very close to a thousand island dressing so you will love it!
Wow, that’s quite a combination of sauces. I wouldn’t mind trying it on my burger, it has everything yummy in it.
You will love it, Joanna! Definitely try it!
Yumm.. that burger sounds delicious!! I’m going to try it for myself.
Jasmine, please do! It is sooo good!
Once again something that I cannot resist 🙂 And those double freid fries sounded exactly what I need right now! Without ideas and recipes it’s so hard to figure out what to cook and make for lunch/dinner etc. New tips are always needed – thanks again Alison!
I feel like I need to try an in and out burger now. I’m from uk so don’t have it. Need to give this a try instead lol
Never tried this sauce before and definitely eager to try it out. I miss thousand island dressing after reading this post

Oh yummy. The sauce really reminds me of the burgers in In and Out but on the fancy side. This sauce is way better because I know what’s it in. Now, I am hungry.
Good Allan, whip some up and please rate our recipe!
Is it 100% necesary to refrigerate this :(? i’m making the burgers today.
It’s better if the flavors blend, however you can mix it up, enjoy and then refrigerator any leftover sauce.
