Creating your own Animal Style Fries is straightforward. Follow these steps for delicious results:

1. Prepare the Potatoes: Wash and peel the russet potatoes. Cut them into fries, ensuring they are evenly sized.
2. Soak in Water: Place the cut fries in cold water for about 30 minutes. This helps remove excess starch and yields crispier fries.
3. Make the Special Sauce: In a bowl, combine mayonnaise, ketchup, mustard, and pickle relish. Mix well and set aside.
4. Fry the Onions: Heat a skillet over medium heat. Add a splash of oil and sauté the sliced onions until they are caramelized and golden brown. Season with salt and pepper. Set aside.
5. Fry the Potatoes: Heat oil in a deep fryer or a large pot to 350°F (175°C). Carefully add the soaked fries in batches, frying until they are golden brown and crispy, about 5-7 minutes per batch.
6. Drain and Season: Remove the fries from the oil and place them on paper towels to drain excess oil. Season with salt immediately.
7. Assemble the Fries: On a large serving plate, place a generous portion of fries. Top them with shredded cheese, followed by the sautéed onions.
8. Melt the Cheese: Place the loaded fries in the oven on broil for 2-3 minutes, or until the cheese is melted and bubbly.
9. Add the Sauce: Drizzle the special sauce over the cheesy fries.
10. Garnish: Optionally, sprinkle with chopped chives for added flavor and presentation.

Following these steps will guarantee that your Animal Style Fries are a hit at any gathering!
