For the Special Sauce

For the Toppings
- Onions – Sweetness deepens when caramelized; shallots can be a milder alternative.

Step‑by‑Step Instructions for Delicious Animal Style Fries In-N-Out Copycat Recipe
Step 1: Caramelize the Onions
In a large skillet, melt 1 tablespoon of butter with 1 tablespoon of neutral oil over medium-low heat. Add 1 cup of diced onions and sprinkle with a pinch of salt. Stir occasionally for about 30 minutes, until the onions are a beautiful golden brown and sweetly fragrant. This caramelization will add depth to your Delicious Animal Style Fries.
Step 2: Prepare the Special Sauce
While your onions are caramelizing, grab a medium bowl and combine ½ cup mayonnaise, 2 tablespoons ketchup, 1 tablespoon rice vinegar, 1 tablespoon sweet relish, 1 teaspoon sugar, and a dash of chili flakes if desired. Whisk all the ingredients together until the mixture is smooth and well blended. This tangy special sauce will elevate your Animal Style Fries to new heights!
Step 3: Cook the Fries
Preheat your oven according to the package instructions for frozen fries. Spread the fries evenly on a baking sheet and bake for the recommended time, usually around 20-25 minutes, until they are crispy and golden brown. Make sure to check for that perfectly crunchy texture which will serve as the base for your Delicious Animal Style Fries.
Step 4: Add Cheese
Once the fries are out of the oven, sprinkle 1 cup of shredded American cheese over the hot fries. Turn on the broiler in your oven and place the fries back in for about 3-5 minutes, just until the cheese is bubbling and melted. Keep a close eye to avoid burning; this step ensures that your Animal Style Fries are gooey and decadent.
Step 5: Assemble Your Fries
Carefully remove the fries from the oven and transfer them to a serving platter. Layer the sweet caramelized onions generously over the cheesy fries, then drizzle the homemade special sauce all over the top. Serve these luscious Delicious Animal Style Fries immediately for a mouthwatering experience that everyone will love.

Make Ahead Options
These Delicious Animal Style Fries are perfect for meal prep enthusiasts! You can prepare the special sauce and caramelized onions up to 3 days in advance, allowing for quicker assembly when you’re ready to serve. Simply make the sauce by mixing mayonnaise, ketchup, rice vinegar, sweet relish, sugar, and optional chili flakes in a bowl, then refrigerate it in an airtight container. For the onions, caramelize them as instructed and let cool before storing them in the fridge. When it’s time to enjoy your fries, bake or fry your fries according to package instructions, layer with cheese and broil, then top with your prepped onions and sauce for that delicious touch—restaurant-quality results with minimal effort!

Animal Style Fries Recipe FAQs
How do I choose the right type of fries for this recipe?
Absolutely! For the best results, I recommend using crinkle-cut frozen fries, as they offer an extra crunch that complements the toppings beautifully. However, if you prefer a fresher taste, homemade fries are a fantastic option. Just ensure they’re cut evenly to cook thoroughly!
How should I store leftover Animal Style Fries?
Leftovers should be placed in an airtight container and stored in the refrigerator for up to 2 days. This keeps them fresh and prevents moisture from making them soggy. When ready to enjoy again, I suggest reheating them in a preheated oven to 400°F (200°C) for about 10-15 minutes for that delicious crisp texture.
Can I freeze my Animal Style Fries?
Yes, you can! To freeze, first assemble your fries with the toppings and let them cool completely. Then, place them in a single layer on a baking sheet and freeze until solid. Once frozen, transfer them into a freezer-safe container or bag where they can last up to 2 months. Simply reheat in the oven when you’re ready for a snack!
What if my caramelized onions are burning instead of browning?
Very! If you notice your onions starting to burn, it’s essential to decrease the heat immediately. Stir them more frequently and add a splash of water to the pan to deglaze and help prevent burning. Patience is key here; they should cook low and slow for about 30 minutes until they reach that perfect golden-brown deliciousness!
Are there any dietary considerations to keep in mind with this recipe?
Of course! For dairy-free options, you can substitute the cheese with a vegan cheese alternative and use vegan butter instead. When preparing the special sauce, Greek yogurt can replace mayonnaise for a lighter version. If you’re serving these to pets or anyone with allergies, be mindful of any ingredients like mayonnaise and relish that could trigger sensitivities.
Can I make the sauce and onions ahead of time?
Definitely! You can prepare the special sauce and caramelized onions up to 3 days in advance. Store both in separate airtight containers in the refrigerator. When you’re ready to enjoy, simply reheat the onions in a pan and assemble the fries when it’s time to serve!
