With a homemade fry sauce, caramelized onions and mustard grilled patty, the In-N-Out Double Double – Animal Style is the perfect GOOD fast food burger as decoded by Kenji from Serious Eats. 
The truth is I live about three blocks from the closest In-N-Out. And they are all as sweet as the shakes they sell. And the lines move quick. And the food is fresh. And they give my little ones stickers and hats. So why did I go through the effort of making this copycat recipe? Well…. A: I am a sucker for a good copycat recipe and B: Kenji from Serious Eats made it which makes me really eager to try it (like the Halal Chicken & Rice).

Kenji is a mad scientist genius and author of the not yet released cookbook The Food Lab which is already a best seller on Amazon even though it is almost a month from being released. Have you ever checked out his recipes? He is amazing and of the dozen or so I have made, I have not been let down a single time. He is a total rockstar. Just like this recipe.

Kenji took a ton of time and effort in decoding the components of this In-N-Out Double Double – Animal Style and with only a couple of small swaps, I followed it to the letter (ie, I cooked the onions in butter instead of oil). If you take care to follow the instructions you will sit down to a meal that will make you feel like you brought In-N-Out Double Double into your kitchen. Don’t be discouraged by the steps involved. They are all easy. Lengthy, but easy. And really precise, just like Kenji.

Here is a little side by side comparison. Actual In-N-Out on the left, my version on the right. My husband felt bad for the poor In-N-Out burger, he thought it looked deflated. Trust me when I say that even if it does not look advertisement ready, that burger is D-E-L-I-C-I-O-U-S!!The burger that has become a legend, the In-N-Out Double Double - Animal Style, with a homemade fry sauce, caramelized onions and mustard grilled patty. dinnerthendessert.com


There are quite a lot of steps in the process, so lets get started. I did actually photograph every step, so if you are hitting a snag anywhere in the recipe drop me a comment and I will upload a photo of the step for you. I also have more photos of the onions and sauce, but I am going to post them in the recipe for the Animal Style Fries that I am posting tomorrow.

Form meat into four 2 ounce patties, thin and slightly larger than the size of your bun. They are meant to be 1/4 inch thick. Heat 1 tablespoon butter in a skillet over medium-high heat until shimmering. Add onions and 1/2 teaspoon kosher salt to skillet. Reduce heat to medium low, and cook, tossing and stirring occasionally until onions are well browned, about 15 minutes.

Once onions begin to sizzle heavily and appear dry, add 1 tablespoon water to skillet and stir. Continue cooking until water evaporates and onions start sizzling again. Repeat process, adding 1 tablespoon of water with each iteration until onions are meltingly soft and dark brown, about 3 times total. Transfer to a small bowl and set aside while leaving any residual butter in the pan.

Preheat oven to 400 degrees. To make the burger and animal fry topping: Add mayonnaise, ketchup, relish, sugar, and vinegar to a small bowl and stir to combine. Place closed buns in preheated oven for 2 minutes until slightly darker and just the slightest bit crispy. Using the butter left behind by the onions, press the buns into the pan and toast for a few seconds until crispy. If there is no butter left in the pan, add a 1/2 a tablespoon or so to the pan.

Season the patties with salt and pepper. Preheat pan on high and add the patties to the pan. Cook without moving until well browned and crusty on first side, about 2 1/2 minutes. While they are cooking, spread about a tablespoon of mustard to the raw side. The burger that has become a legend, the In-N-Out Double Double - Animal Style, with a homemade fry sauce, caramelized onions and mustard grilled patty. dinnerthendessert.com

If you prefer not to enjoy this animal style
1. Use a 1/4 inch thick slice of raw onion instead of caramelized onion
2. No pickles
3. No mustard on the patty

Dinner then Dessert TIPS Make the sauce and the onions the day before. I also cut and soak my potatoes the night before. It eliminates a lot of the starch that prevents the perfect crispy fry. And if the method is good enough for Balthazar NYC and their perfect fries, it is good enough for me!The burger that has become a legend, the In-N-Out Double Double - Animal Style, with a homemade fry sauce, caramelized onions and mustard grilled patty. dinnerthendessert.com

  1. In-N-Out causes quite a stir. I know how incredible their burgers are, but yours does look even better. Can’t wait to try it.

  2. We don’t have any In-N-Out places near us but my friends RAVE about them. This sure looks delicious and we love to grill. Will have to try it soon.

    1. Yup, I’ve made it both ways and can’t even explain how the mustard affects it. I just know with mustard tastes SO much better!

  3. I have never been to an In-N-Out, they don’t have them here, so thanks for the copycat recipe idea I need to try this out! 🙂

  4. you know, they just opened an in and out near us, but I haven’t been yet… This burger sounds amazing. I will be giving the recipe a try

  5. I have not been to this place, but I will gladly say how delicious this burger looks! Definitely a must try! Maybe I’ll attempt to make it with your recipe!

  6. Oh. My. Goodness. We don’t have In and Out (I’m pretty sure) here in Atlanta, but I ate there all the time when I was in college in Utah! I’m going to have to make these asap to fulfill that IN and Out hole in my heart!

    Paige

  7. I am a west coast girl that has grown into an In N Out loving lady learning the secret behind Animal Style is equal to discovering a rare hidden gem. I bet your version is even better than the original and that is saying a lot.

    1. You’re awesome Marcie! When I found the recipe I did a serious happy dance because Kenji got super scientific about figuring out all the details.

  8. We absolutely love In and Out burger! It’s so delicious! This is actually the husband’s favorite item there! I need to show him this recipe! He can recreate it all on his own now!

  9. Sabrina you need a warning label on your blog post ‘Warning the deliciousness of this post may make you crazy’! I’m completely starving now and nothing will do except one of this amazing burgers! This is really fantastic.

  10. The last time we were in Cali, I had an In N Out burger. Holy moly. I have never tasted a burger so fantastically amazing. Ever.

  11. I know my boyfriend has always wanted to try one of those burgers. We’ll have to try this out and make some for ourselves!

    1. Yeah they have a rule that in order to have a location they have to be within a single day’s drive from the distribution center here in CA. They don’t freeze food (ever, the locations have no freezers) so it is both cool and sucks for people further away.

        1. Yup! They never freeze it and there aren’t any additives. Buns are baked fresh for them, beef is fresh. When you are in the drive through you can see them peeling fresh potatoes… all quality.

    1. That is part of the signature to the animal style. If you were to order a normal burger, not “animal style” they don’t do the mustard grill part.

    1. Yay! I hope he loves it! We did side by side taste comparisons and the only flavor difference was the bun (in n out has a company make theirs for them so they are not readily available)

    1. Yup! I had finished the whole meal prepping and cooking in the time it took my husband to get there and go through the drive through. We only live 3 minutes away from it!

  12. Oh my goodness, I can’t wait to try this! We are from California and miss those tasty burgers! Thanks for sharing, I know this will get my son home from college for a weekend visit! 😉

  13. A double-double?! Oh. My. Goodness! I’m almost afraid to share this with our boys; what an animal-style sandwich indeed! That said, this looks other-worldly mouthwatering!! Nice job!

  14. Wow…and YUM! I am SO impressed by your amazing looking replica. I lived near an In-and-Out for 12 years, and now we haven’t had one near us for 3 years. But your tutorial might just help me to get my In-and-Out fix for the first time in a long time.

    1. I know, right? Poor burger. I wasn’t even trying to make it look bad but when I tried to adjust it the melted cheese had cemented it together as it was and it would tear the bun so I had to leave it!

  15. In N Out is always our first stop on the west coast, but since we don’t have any here in the east, we have no choice than to make our own.

    1. When I was in college on the East Coast I did the exact same thing every time I came home for visits! We went to the one right by LAX so there was no time wasted!
