Kenji’s delicious recipe for the Double Double Animal-Style Cheeseburger was such a spot on hit, I’ve carried it through to the next day to recreate the Animal Style French Fries to accompany it. Kenji declined to make the French fries because he declared that In-N-Out has never really been known for their fries. This, I hate to admit, is pretty true. The French fries were always the weakest link in the very short chain of a menu with only a double cheeseburger, cheeseburger, hamburger and fries on the menu.
The animal style French fries however are another story. They are wonderful, but with a fault. Because In-N-Out French fries are only fried once before serving you don’t get the ultra crispy fries you are used to in a fast food place. Any other burger shop you go to is going to fry frozen pre-fried potatoes so that they get the elusive double fry.
So I did what any self respecting fry enthusiast would do. I took the idea of the animal style French fries and fixed the only flaw it had, the single fry and instituted the important double fry. The result are a more crispy french fry that doesn’t immediately get soggy under the weight of its toppings.
Keep the sliced potatoes in a bowl of cold water while you prepare the rest of the ingredients. 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.
