Vegan Double Double Animal Style

Updated: Jul 16, 2020

If you're a vegan in California and miss In n' Out, or if you've never had one and want to know what all the hoopla is about, this is the VEGANIZED Burger for you!

Okay, I know there's no shortage of recipes for a Double Double, but oddly enough, a cursory glance for a Vegan Double Double Animal Style comes up with no results! I doubt I'm the first one to do this, but either way, here's another recipe!

Growing up in California, I've eaten my fair share of these, and I gotta say, this comes eerily close to what I remember. There's a few things that make this burger unique. First is the caramelized onions, something you don't see very often from a fast food joint (to be fair, anybody who's waited in line for over 30 minutes knows In n' Out isn't really fast food).

To make the onions, I just used a bunch of butter and some oil, then cooked them in a large skillet over medium low heat for about 30 minutes. You'll wanna stir them every minute or so and add a little bit of water if they start to dry out or stick to the pan. Adding a pinch of sugar and salt will help them cook up as well.

The other thing is the copious amounts of their famous sauce. The sauce is actually pretty much what I usually make for a standard burger sauce these days. It's just vegan mayo, ketchup, sweet relish and vinegar. That's it!

And lastly but not leastly, is before you flip your burger patties, you give 'em a nice squirt of yellow mustard. This caramelizes the mustard to the patty. Sounds weird but it's super good I swear!

In any case, like I said, if you're vegan and have been jonesing for one of these, give this recipe a try, it cures my In n' Out cravings every time!

Makes 1 Burger

  • Two (3 oz) plant based burger patties

  • 2 slices vegan cheese

  • Tomato slice

  • Iceburg or Butter lettuce

  • Dill Pickle slices

  • 1 Burger Bun

  • 1 Onion (diced)

  • 2-3 Tbsp vegan butter

  • Yellow Mustard

Special Sauce

  • 2 Tbsp vegan mayo

  • 1 Tbsp ketchup

  • 1/2 Tbsp sweet relish

  • 1/2 Tbsp (or more) white vinegar


  1. The most time consuming part of this is grilling the onions, so let's start that before anything else. Add a heaping Tbsp of vegan butter and melt in a saucepan over medium heat. Once melted, add some cooking oil of choice, your onions and sprinkle a bit of salt and sugar. Stir it frequently, when it starts to brown, lower the heat to medium low.

  2. Now as the onions continue to cook, go ahead and get the rest of your burger stuff ready. Keeping an eye on and stirring the onions to make sure they aren't getting burnt or sticking to the pan. If they do stick to the pan, just deglaze with a little water. Since it will take about 30 minutes to cook the onions, you can really take your time here.

  3. This is optional, but I like to brush my buns with a bit of melted butter and then put them in the oven and keep them warm. Totally up to you, but it's a good move :)

  4. Get your lettuce, tomato and pickles all set up and ready to go.

  5. Combine all the ingredients for the sauce and adjust to your taste. A lot of copycat recipes add sugar to it, but I found this to be too sweet for my palette.

  6. Once the onions look like they are pretty much done (they should be completely soft, a lovely dark reddish brown, and taste like oniony heaven), lower the heat to just keep them warm. Then, melt some more butter in a skillet over medium high heat. Once melted, add your 2 plant based burger patties. Cook for about 3-4 minutes.

  7. Before flipping your burger patties, squirt about a tablespoon of mustard on each. Flip your patty, add the cheese and top with the onions. Add about a tablespoon of water in the pan and then cover. The steam from the water will help the cheese melt.

  8. Once cheese has melted, assemble burger as follows from bottom to top: Sauce, Pickles, Tomato, Lettuce, 2 Burger Patties, any leftover onions, more sauce, top bun!

  9. ENJOY!
