Instructions
Let’s dive into the steps to create this flavorful masterpiece:
Cook the Fries
Bake or fry the French fries according to the package instructions or until golden and crispy. For extra crunch, air fry them at 400°F for about 15 minutes, shaking halfway through.
Caramelize the Onions
In a pan over medium-low heat, cook finely chopped onions with a little butter and a pinch of salt. Stir occasionally until they turn soft, golden brown, and caramelized—this takes about 15-20 minutes.
Make the Animal Style Sauce
In a small bowl, mix mayo, ketchup, mustard, relish, and vinegar until smooth. This sauce is what brings everything together, so don’t skip it!
Assemble the Fries
While the fries are still hot, place the American cheese slices on top, allowing them to melt slightly.
Add the Toppings
Spoon the caramelized onions over the fries, then drizzle generously with the Animal Style sauce.
Serve and Enjoy
Grab a fork (or just dig in with your hands) and enjoy every cheesy, saucy, crispy bite!

FAQ’s
1. Can I make these fries ahead of time?
It’s best to enjoy them fresh, but you can prep the sauce and onions in advance and reheat them before serving.
2. What kind of cheese should I use?
American cheese is the best choice for that classic melty texture, but you can also use cheddar or a mix of cheeses.
3. How do I store leftovers?
Store components separately in the fridge, then reheat the fries in the oven or air fryer before assembling.
4. Can I use frozen fries?
Yes! Frozen fries make this recipe super easy and quick. Just cook them until extra crispy.
5. What’s the best way to caramelize onions?
Low and slow! Cook them over medium-low heat, stirring occasionally, for 15-20 minutes until golden brown.

Use an oven or air fryer at 375°F for 5-10 minutes to keep them crispy. Avoid microwaving, as they’ll get soggy.
8. Can I make this sauce dairy-free?
Yes! Use vegan mayo and skip the cheese or use a dairy-free cheese alternative.
9. What type of fries work best?
Thin-cut fries are the closest to In-N-Out’s, but crinkle-cut or waffle fries also work great.
