Preparing Copycat In-N-Out Animal-Style Fries
If you’ve ever craved the deliciousness of In-N-Out’s Animal-Style Fries but don’t want to make the trek to your nearest location, you’re in luck! Perfecting the art of Copycat In-N-Out Animal-Style Fries can be done right in your kitchen, and it’s easier than you might think. Let’s dive into how to whip up this iconic dish step-by-step!
Sautéing the onions
First things first, the onions are the stars of this dish. Start by heating 2 tablespoons of vegetable oil in a large frying pan over medium heat until it shimmers—this is the golden moment! Add the finely chopped medium yellow onions, seasoning them with a pinch of kosher salt. Sauté for about 10 minutes until they start to soften; then cover the pan and let them cook, stirring occasionally, for about 40 to 45 minutes. You want those onions to turn a rich, dark golden brown for maximum flavor. Onions are not just a topping; they bring that sweet, caramelized essence to the plate.
Making the special sauce
While your onions are working their magic, it's time to create the luscious special sauce that makes these Copycat In-N-Out Animal-Style Fries truly one-of-a-kind. In a medium bowl, mix together ⅔ cup of mayonnaise, ¼ cup ketchup, 3 tablespoons sweet pickle relish, 1 tablespoon yellow mustard, and 1 teaspoon distilled white vinegar. Blend until everything is well combined. This sauce has that perfect blend of tangy and creamy, reminiscent of the original.
Baking the fries
Next, let’s get those fries baking! Preheat your oven to 425ºF, and while that’s warming up, line two baking sheets with a light coating of oil. Spread out 32 ounces of frozen french fries evenly across the sheets. Bake until they turn light golden brown and crisp—this should take about 25 minutes. Be sure to stir the fries halfway through for an even bake and to switch the sheets between the oven racks. This little trick helps them get that delicious, crispy texture we all love about french fries!
Layering the cheese and toppings
Now that your fries are golden and crispy, it’s time to layer on the cheese and toppings for the ultimate indulgence. Place a slice of American cheese on top of the hot fries to allow it to melt perfectly. Once the cheese is gooey and has that glorious stretch, it’s time to pile on the sautéed onions and drizzle on your special sauce—don’t hold back on this step!
Serving it all together
Finally, serve your Copycat In-N-Out Animal-Style Fries immediately. Consider pairing them with a refreshing soft drink or maybe a homemade milkshake for that ultimate diner experience. These fries are a perfect shareable snack for any gathering or a satisfying treat for yourself after a long week. Don’t forget to take a photo of your delicious creation before diving in—you’ll want to show off your culinary skills!
