How to Make Indulgent Animal Style Fries: Your Ultimate Copycat In-N-Out Recipe!

1. Start by rinsing and soaking your cut fries in cold water for 15 minutes to remove excess starch, then pat them dry thoroughly with paper towels.
2. Heat the vegetable oil in a deep fryer or large heavy pot to 325°F. Fry the potatoes in batches for 4-5 minutes until soft but not browned. Remove and drain on paper towels.
3. Increase the oil temperature to 375°F and fry the potatoes again in batches for 2-3 minutes until golden and crispy. Drain again and season immediately with salt and pepper.
4. While the fries cook, melt butter in a skillet over medium heat. Add the finely chopped onion and cook for 10-12 minutes, stirring often, until deeply caramelized and fragrant. Set aside.
5. Mix all secret sauce ingredients in a small bowl until smooth. Taste and adjust seasoning if needed.
6. Preheat your oven to 400°F. Spread the crispy fries in a single layer on a baking sheet. Sprinkle evenly with shredded American cheese, then top with a generous layer of caramelized onions.
7. Bake for 5-7 minutes, or until cheese is melted and bubbly.
8. Remove from oven, drizzle with secret sauce, and serve immediately while hot and gooey.

Tips for the Best Results

• Make sure to dry your fries completely after soaking to achieve maximum crispiness.
• Double frying is key for fries that are crispy on the outside and tender inside.
• Use fresh yellow onions for rich, sweet caramelized onion flavor.
• Adjust secret sauce ingredients to suit your taste—add a little more pickle relish for tanginess.
• Serve immediately to enjoy fries at their warmest and crispiest.

Storage and Reheating

Store leftover fries in an airtight container in the refrigerator for up to 2 days. To keep them crispy, reheat them in an oven or air fryer at 375°F for 5-7 minutes rather than microwaving.

The secret sauce should be kept separate and refrigerated for up to a week. Avoid freezing the fries as they lose texture when thawed.

Frequently Asked Questions

Can I make animal style fries in an air fryer?

Yes, you can air fry the potatoes to make them crispy, but results may differ slightly from deep frying. Cook at 375°F for about 20-25 minutes, shaking halfway through.

What cheese works best for animal style fries?

American cheese is ideal because it melts smoothly and has a creamy texture, which replicates the classic In-N-Out experience perfectly.

Can I prepare the caramelized onions ahead of time?

Absolutely! Caramelized onions can be made in advance and stored in the fridge for up to 3 days, making assembly faster when you’re ready to serve.

Is there a vegetarian version of animal style fries?

This recipe is naturally vegetarian since it uses vegetable oil, cheese, and plant-based ingredients. Just be sure your cheese is free of animal rennet if you prefer fully vegetarian options.
