In-N-Out Animal Style Fries (Copycat Recipe)
If I’m at In-N-Out, I’m getting In-N-Out animal style fries. They’re crispy, cheesy, and covered in grilled onions and that tangy secret sauce.
Since I live on the East Coast and there’s no In-N-Out anywhere near me, I had to figure out how to make them at home. Turns out, it’s pretty easy, and they taste so good!

Ingredients:
For the Fries:
- 4 large russet potatoes, cut into fries (or use frozen fries for a quicker option)
- 2 tbsp olive oil
- Salt, to taste
For the Animal Style Sauce:
- 1/4 cup mayonnaise
- 2 tbsp ketchup
- 1 tbsp yellow mustard
- 1 tbsp pickle relish (or finely chopped pickles)
- 1 tsp garlic powder
- 1 tsp onion powder
- 1/2 tsp paprika
- 1 tsp white vinegar (optional, for a tangy kick)
Instructions:
Prepare the Fries:
- Preheat your oven to 425°F (220°C).
- Wash and peel the potatoes (if desired), then cut them into fries (about 1/4-inch thick).
- Toss the fries in a large bowl with olive oil and salt to coat evenly.
- Lay the fries in a single layer on a baking sheet lined with parchment paper or a silicone baking mat.
- Bake for about 25-30 minutes, flipping halfway through, until the fries are crispy and golden.
Make the Animal Style Sauce:
- While the fries are baking, combine mayonnaise, ketchup, mustard, pickle relish, garlic powder, onion powder, paprika, and white vinegar in a bowl.
- Mix well until the sauce is smooth and fully combined. Adjust the seasoning to taste if needed. Set aside.
Caramelize the Onions:
- In a skillet, melt butter over medium heat.
- Add the thinly sliced onions and a pinch of salt. Cook, stirring occasionally, for 10-15 minutes until the onions are soft, golden, and caramelized.
Assemble the Animal Style Fries:
- Once the fries are crispy and golden, remove them from the oven and immediately top with the shredded cheese. You can pop them back in the oven for a minute or two to melt the cheese, if desired.
- Drizzle the fries generously with the Animal Style sauce.
- Top with the caramelized onions.
- Serve hot and enjoy!
