If you’re not familiar with In-N-Out, it’s a fast-food burger joint that started on the West Coast. It’s been around a long time (1948) but has stayed small because they never allowed franchises to keep control of the quality. Just like when McDonalds started, In-N-Out focuses on only serving great burgers (and also soda, fries & shakes).

In-N-Out only offers a few varieties of their burger: hamburger, cheeseburger, and double-double (2 patties and 2 slices of cheese). There are a few “secret menu” variations that you can order including increasing the patty count (3×3 or 4×4), protein style (wrapped with lettuce instead of a bun), or Animal Style. For our In-N-Out burger recipe, we’ll build a double-double animal style.

An Animal Style burger is slightly different from the standard burger because it has grilled onions, pickles, and extra special sauce. It’s also cooked with some yellow mustard.

In-N-Out has their own burger sauce that is unique to the chain. You can pretty closely replicate it by combing 2 parts mayo, 1 part ketchup and some sweet relish. The sauce really enhances the burger to make this guy taste authentic.

The rest of the burger is pretty simple. Just high quality ingredients. One trick for the animal style burger is to top your burger with some yellow mustard before flipping it. This cooks some extra flavor into the meat.

The standard burger has regular onions on it, but the animal style has them diced and grilled. It’s up to you what you’d prefer. Finally, the bottom of the burger has 4 pickle chips added.

If you’ve got a chance to try out an In-N-Out go for it, they’re great! But if not, give this In-N-Out burger recipe a try to see why it’s so good!
