Craving fast food at home? Animal-style fries are the ultimate indulgent comfort food, and now you can make them right in your own kitchen. Inspired by the famous In-N-Out version, this copycat recipe features crispy fries smothered with melty cheese, grilled onions, and a tangy, creamy “secret sauce.” It’s a viral hit on Pinterest, and for good reason.
🛒 Ingredients:
- 1 bag frozen French fries or homemade fries
- 1/2 cup shredded American or cheddar cheese
- 1 large onion, finely diced
- 1 tablespoon butter
- Salt to taste
Secret Sauce:
- 1/4 cup mayonnaise
- 2 tablespoons ketchup
- 1 tablespoon sweet pickle relish
- 1 teaspoon mustard
- Dash of vinegar or pickle juice

📝 Instructions:
- Make the Sauce: Mix all sauce ingredients and chill in the fridge.
- Caramelize the Onions: In a skillet, melt butter and cook onions over medium-low heat for 20–25 minutes until golden brown.
- Bake or Fry the Fries: Cook fries according to package instructions or deep fry until golden and crisp.
- Assemble the Fries: Place hot fries on a plate, sprinkle with cheese, then top with warm caramelized onions and a generous drizzle of sauce.
- Serve Immediately: Enjoy while hot and gooey!
🔥 Tip:
Use waffle fries for extra texture and topping hold.
