Ingredients
Key ingredients
To recreate this iconic dish, gather the following ingredients:
- 1/2 cup mayonnaise
- 2 tablespoons ketchup
- 1/2 tablespoon rice vinegar (or white vinegar)
- 2 tablespoons sweet relish
- 1 tablespoon sugar
- 1/2 tablespoon chili flakes (optional)
- 1/2 bag frozen French fries
- Cheddar cheese or American cheese
- 2 onions (diced)
- 2 tablespoons butter
- 1 tablespoon neutral oil
- 1/2 teaspoon salt
These ingredients blend together to create the magic that is In-N-Out’s Animal Style Fries. Feel free to swap in your favorite types of cheese or adjust the seasoning to your taste. For a healthier alternative, consider using air-fried fries or making your own from scratch.

Directions
Cooking method
- Start with the onions: Melt the butter in a pan over medium-low heat, then add the neutral oil. Once melted and warm, toss in the diced onions and salt. Stir occasionally, allowing the onions to caramelize. This process can take about 30 minutes or longer; keep an eye on them to prevent burning.
- Prepare the sauce: While the onions are cooking, combine the mayonnaise, ketchup, rice vinegar, sweet relish, sugar, and chili flakes in a bowl. Mix until well combined and set aside.
- Cook the fries: Bake or fry the frozen fries according to the package instructions until they are golden and crispy.
- Melt the cheese: Once the fries are cooked, lay them on a baking sheet. Top with grated cheddar or sliced American cheese, and broil for 3-5 minutes or until the cheese is bubbly and melted.
- Assemble: Once the cheese has melted, remove the fries from the oven. Spoon the caramelized onions generously over the cheesy fries and drizzle with the special sauce.
- Serve immediately: Enjoy your homemade In-N-Out Imitation Animal Style Fries while they’re hot for the best experience!
How to serve In-N-Out Imitation Animal Style Fries
Best ways to enjoy it
Once you’ve prepared your delectable fries, it’s time to think about how to serve them for maximum enjoyment. These fries can stand alone as a meal or serve as a fantastic side dish paired with burgers, hot dogs, or grilled meats.
For a more indulgent experience, consider serving these fries alongside a creamy ranch dip or additional sauces like barbecue or hot sauce. Garnish with chopped green onions for a pop of color and added flavor.
How to store
Keeping leftovers fresh
If you’re lucky enough to have leftovers, storing them properly is key to keeping them delicious for the next day. Here’s how to do it safely:
- Refrigerator: Allow the fries to cool completely before storing them in an airtight container. They should keep well in the fridge for about 2-3 days.
- Freezing: Although it’s not recommended for the best texture, you can freeze leftover fries. Lay them flat on a baking sheet to freeze before transferring them to a freezer-safe bag. They can last up to a month.
- Reheating: To reheat, use an oven or air fryer at 350°F for about 10-15 minutes. This will help restore some crispiness compared to microwaving.
Tips to make
Helpful cooking tips
- Caramelizing tip: Patience is essential when caramelizing onions. Cooking them slowly helps develop the sweet flavor. If they’re cooking too fast, lower the heat.
- Cheese option: American cheese melts beautifully, giving you that classic taste. However, if you prefer a sharper flavor, try cheddar or a blend.
- Fry alternatives: For a healthier twist, consider making your fries from scratch using sweet potatoes or zucchini. Adjust cooking times accordingly, as these will vary based on thickness.
Variations
Creative twists

- Veggie add-ins: Top your fries with cooked mushrooms, or even chili to make it a heartier dish.
- Cheese overload: Mix different cheeses like pepper jack or fontina for a melty, rich experience.
