Making Animal Style Fries is simple if you follow these steps:

1. Prepare the Potatoes: Wash and peel the russet potatoes. Cut them into thick fries.
2. Soak the Fries: Soak the cut potatoes in cold water for at least 30 minutes. This helps remove excess starch for crispier fries.
3. Heat the Oil: In a deep frying pan or pot, heat vegetable oil to 350°F (175°C).
4. Fry the Potatoes: Drain the soaked fries and pat them dry. Fry the potatoes in batches until golden brown and crispy, about 4-5 minutes per batch. Remove and drain on paper towels.
5. Cook the Onions: In a separate skillet, sauté the sliced onions over medium heat until they are caramelized, about 10-12 minutes. Season with salt and pepper to taste.
6. Make the Special Sauce: In a small bowl, mix the mayonnaise, ketchup, and yellow mustard until well combined.
7. Assemble the Fries: Place the hot fries on a serving platter. Sprinkle the shredded cheddar cheese generously over the fries. Top with the sautéed onions and drizzle the special sauce over everything.
8. Optional Toppings: Add any additional toppings you desire, such as pickles or jalapeños.
9. Serve Immediately: Enjoy your Animal Style Fries while they’re hot and crispy.

These steps will guide you through creating a mouthwatering dish that will leave your guests asking for seconds.
