Ingredients

Scale

For the Fries:

2 large russet potatoes (or use frozen fries for convenience)
2 tbsp vegetable oil
Salt, to taste

For the Animal Style Sauce:

½ cup mayonnaise
2 tbsp ketchup
1 tbsp yellow mustard
1 tbsp sweet pickle relish
1 tsp white vinegar
½ tsp sugar

For the Toppings:

1 large onion, finely chopped
1 tbsp butter
1 tsp sugar
4 slices American cheese

Instructions

1️⃣ Prepare the Fries

Cut russet potatoes into fries and soak them in cold water for 30 minutes (removes excess starch for crispier fries).
Drain, pat dry, and toss with vegetable oil & salt.
Bake at 425°F (220°C) for 25 minutes, flipping halfway OR air-fry at 380°F for 15 minutes until crispy.

2️⃣ Make the Sauce

In a bowl, mix mayonnaise, ketchup, mustard, relish, vinegar, and sugar.
Stir until smooth and refrigerate while prepping the onions.

3️⃣ Caramelize the Onions

Heat butter in a pan over medium-low heat.
Add chopped onions and sugar, then cook for 15 minutes, stirring occasionally until golden brown.

4️⃣ Assemble the Fries

Place cooked fries on a plate.
Lay cheese slices on top and let them melt (or pop them under the broiler for 1 minute).
Spoon caramelized onions over the cheese.
Drizzle generously with Animal Style sauce.

5️⃣ Serve & Enjoy!

Grab a fork and dig in while they’re hot! 😋

Notes

✔️ Shortcut? Use frozen fries for a faster version!
✔️ Spice it up! Add a dash of hot sauce or cayenne to the sauce.
✔️ Melty cheese hack: Instead of slices, use shredded American or cheddar cheese for better coverage!
