For the Fries

• ½ bag frozen fries
• 1 tablespoon neutral oil
• ½ teaspoon salt

For the Caramelized Onions

• 2 onions, finely chopped
• 2 tablespoons butter

For the Animal Style Sauce

• ½ cup mayonnaise
• 2 tablespoons ketchup
• 2 tablespoons sweet relish
• 1 tablespoon sugar
• ½ tablespoon rice vinegar
• ½ tablespoon chili flakes

For Topping

• 1 slice cheddar cheese or American cheese

Directions

1. Prepare the Fries

1. Cook the frozen fries according to the package instructions. For extra crispiness, bake or air-fry at 400°F (200°C) for 15-20 minutes, flipping halfway.

2. Caramelize the Onions

2. Heat butter in a pan over medium-low heat.
3. Add chopped onions and cook, stirring occasionally, for 15-20 minutes until golden brown and caramelized.

3. Make the Animal Style Sauce

4. In a bowl, whisk together mayonnaise, ketchup, sweet relish, sugar, rice vinegar, and chili flakes until smooth.

4. Assemble the Animal Style Fries

5. Melt the Cheese – Once the fries are cooked, immediately place the cheese slices on top so they melt. You can also broil them for 1-2 minutes for extra meltiness.
6. Add Toppings – Spoon the caramelized onions over the cheese-covered fries.
7. Drizzle with Sauce – Generously top with the prepared Animal Style sauce.

5. Serve and Enjoy

8. Serve immediately while warm and enjoy the homemade In-N-Out experience!

FAQs

Can I use fresh potatoes instead of frozen fries?

Yes! Cut russet potatoes into fries, soak them in water for 30 minutes, dry thoroughly, and bake or fry until crispy.

What type of cheese should I use?

American cheese is the most authentic, but cheddar or Monterey Jack also work well.

How can I make my fries crispier?

Bake or air-fry at a high temperature and avoid overcrowding the tray.

Can I make the sauce ahead of time?

Yes, the sauce can be stored in the fridge for up to 5 days in an airtight container.

What oil should I use for cooking?

A neutral oil like canola, vegetable, or avocado oil works best for frying.

How do I prevent my onions from burning?

Cook them low and slow, stirring occasionally to ensure even caramelization.

Can I make this recipe vegetarian?

Yes! Just ensure your cheese is vegetarian-friendly and opt for plant-based mayo.

Can I skip the sugar in the sauce?

Yes, but it helps balance the flavors. Try honey or maple syrup as alternatives.

How can I make this meal more filling?

Top with grilled chicken, ground beef, or black beans for added protein.

Can I double this recipe?

Absolutely! Just adjust ingredient quantities and cook fries in batches if needed.
