How to make In-N-Out Animal Style Fries:
**scroll down for full ingredients list and printable directions**
- Get all the ingredients together: frozen french french fries, an onion, American cheese slices, and In-N-Out Sauce.
- Make the sauce:
- ½ cup mayonnaise (reduced fat or regular)
- 3 TBS ketchup
- 1 tsp yellow mustard
- 1 tsp white vinegar
- 2 ½ TBS sweet pickle relish
- dash of salt & dash of black pepper
- Mix all in a bowl, then place in the fridge to meld the flavors.
- Cook the french fries: Make homemade french fries or frozen french fries. I use frozen because it's easier. Throw them in the Air Fryer for quick cooking (Air Fryer French Fry recipe here).
- While the fries are cooking, caramelize the onions: Add butter to a skillet, then add chopped onions. Cook for 5 minutes over medium heat, sautéing. Add a pinch of salt and pepper, then cook 5 more minutes, sautéing while cooking. Once the onions are browned they are done.
- Preheat the oven to BROIL.
- Spread the cooked french fries in an even layer on a baking covered with parchment paper or foil. Add 4 slices of American cheese over the top of the fries. Place into the oven and broil for 5 minutes, watching it closely. Once the cheese is melted they are done. *Broil time may vary based off your oven, so watch them carefully while they are cooking* Remove from oven.
- Spread cooked onions over the top evenly. Spread In-N-Out Sauce over the top. Eat immediately!!
This copycat recipe will be your absolute favorite! It is SPOT ON for the original Animal Style Fries from In-N-Out! They are so easy to make and can be done in less than 20 minutes.
