Ingredients

Units Scale

For the Fries:

  • 1/2 bag frozen fries
  • 1 tbsp neutral oil
  • 1/2 tsp salt

For the Caramelized Onions:

  • 2 onions, finely diced
  • 2 tbsp butter
  • 1 tbsp sugar
  • 1/2 tbsp chili flakes (optional, for spice)

For the Animal-Style Sauce:

  • 1/2 cup mayonnaise
  • 2 tbsp ketchup
  • 2 tbsp sweet relish
  • 1/2 tbsp rice vinegar

For Topping:

  • Cheddar cheese or American cheese, sliced

Instructions

1. Prepare the Fries:

  1. Cook the frozen fries according to package instructions, either by baking, air-frying, or deep-frying. Sprinkle with salt once done.

2. Make the Caramelized Onions:

  1. In a skillet over medium heat, melt butter and add diced onions.
  2. Stir in sugar and chili flakes (if using). Cook for 15-20 minutes, stirring occasionally, until golden brown and caramelized.

3. Make the Animal-Style Sauce:

  1. In a small bowl, mix mayonnaise, ketchup, sweet relish, and rice vinegar until well combined.

4. Assemble the Animal Style Fries:

  1. Arrange hot fries on a serving plate. Place slices of cheddar or American cheese on top and let them melt.
  2. Spoon over caramelized onions and generously drizzle with Animal Style sauce.
  3. Serve immediately and enjoy!

Notes

  • Extra Crispy Fries? Double-fry them for restaurant-quality crunch.
  • Cheese Melting Tip: Place the fries with cheese under a broiler for 1-2 minutes to melt faster.
  • Spicy Kick: Add extra chili flakes or a dash of hot sauce to the sauce.
  • Storage: Best enjoyed fresh, but caramelized onions and sauce can be made ahead and stored in the fridge for up to 3 days.
