Animal Fries Recipe
Crispy fries, melted cheese, grilled onions, and a creamy secret sauce. It’s comfort food at its finest.
That’s why I’ve came up with this animal fries recipe that walks you through how to make Animal Fries from scratch — or take shortcuts when you’re in a hurry.

Ingredients You’ll Need
For the fries:
- 3 large Russet potatoes (or frozen fries for shortcut)
- Vegetable oil (for frying)
- Salt
For the grilled onions:
- 2 medium yellow onions
- 1 tbsp butter or oil
- Pinch of salt
For the cheese:
- 4 slices of American cheese (or any melty cheese like cheddar or Colby Jack)
For the In-N-Out style spread:
- 1/2 cup mayonnaise
- 3 tbsp ketchup
- 1 tbsp yellow mustard
- 1 tbsp finely chopped dill pickles or pickle relish
- 1 tsp white vinegar
- Pinch of sugar (optional)
Step 1: Make the Caramelized Onions
Here’s how to make them:
Chop onions finely — the smaller, the better. Heat a pan over low heat. Add butter or oil. Toss in the onions and a pinch of salt.
Let them cook slowly, stirring often. After 20–30 minutes, they’ll turn golden brown and soft. Pro tip: Add a splash of water if they start sticking.
Step 2: Make the Spread (aka Secret Sauce)
Uust mix everything together in a bowl: Mayo, ketchup, mustard, chopped pickles or relish, vinegar and optional sugar for sweetness.
Stir well until smooth. Taste it. Adjust it. Add more mustard if you want a tangier flavor. Or a bit more relish for sweetness.
Step 3: Make the Fries
You’ve got two options here: homemade or store-bought.
For The Homemade Fries
Wash and peel your potatoes. Cut them into thin matchsticks or thicker steak-style fries. Soak them in cold water for 30 minutes to remove excess starch.
Dry completely with a towel. Heat oil to 350°F (175°C) and fry in batches until golden and crisp. Remove and place on a paper towel-lined tray. Sprinkle with salt.
Step 4: Cheese It Up
Place the hot fries on a serving plate or tray. While the fries are still hot, lay slices of American cheese right over them.
The heat will melt them beautifully. If they need help, microwave for 15 seconds. Or stick the whole tray under a broiler for 1 minute.
Step 5: Top with Onions and Spread
Spoon those caramelized onions over the cheesy fries. As much as you like. Then drizzle — or dollop — your homemade Animal-style spread on top.
The warm fries and cheese mix with the cool, tangy sauce and sweet onions.
Clean-up Tips
This dish is delicious, but it can get messy. Use parchment paper on your tray or plate to save time.
Soak your pans (especially the onion one) as soon as you’re done. And if you’re frying at home, make sure to dispose of oil properly. Never pour it down the sink.
Why You’ll Love This Recipe
It’s fast food, but better. You control the ingredients. You choose the quality. And the best part? You made it yourself.
Want to make it healthier? Bake the fries. Use light mayo. Add more veggies. Want to make it indulgent? Go wild with cheese.
How to Serve Animal Fries
Serve hot. Always.
These are best eaten fresh, when the cheese is still gooey and the fries are crisp.
They’re great as:
- A party appetizer
- A game day snack
- A side with burgers
- A midnight craving buster
Or let’s be honest — just eat them by themselves. No judgment.
Can You Store Leftovers?
Technically, yes. But honestly, Animal Fries aren’t meant for leftovers.
Reheating can make them soggy. If you really must store them:
- Keep toppings separate from fries. Use an air fryer or oven to reheat fries for crispiness. Microwave the sauce and onions separately
At Last, A Quick Recap
Here’s the play-by-play in case you want a refresher:
- Caramelize onions – low and slow
- Make the spread – mayo, ketchup, mustard, relish
