Ingredients

For the Burgers:

  • 1 lb ground beef (80/20)

  • 4 potato buns

  • 4 slices American cheese

  • 4 slices tomato

  • 1 cup shredded iceberg lettuce

  • 1/2 cup caramelized onions (from 2 onions)

  • 1 tbsp butter (for toasting buns)

  • Salt and black pepper to taste

For the Animal-Style Sauce:

  • 1/2 cup mayonnaise

  • 3 tbsp ketchup

  • 1 tbsp sweet pickle relish

  • 1 tsp white vinegar

  • 1/4 tsp salt

  • Optional: 1/2 tsp sugar

For the Fries:

  • 1 pack frozen French fries (or 200g fresh potatoes, cut and fried)

  • 1/2 cup caramelized onions

  • 1/2 cup prepared animal-style sauce

  • 1 slice American cheese, melted

  • Optional: 130g mashed potatoes (for loaded version)

For the Buns (optional, from scratch):

  • 560g bread flour

  • 45g granulated sugar

  • 12g salt

  • 8g instant yeast

  • 70g unsalted butter

  • 275g milk

  • 1 egg

  • 1 tbsp milk (for egg wash)

Instructions

  • Make the Sauce: Combine mayo, ketchup, relish, vinegar, and salt (plus sugar if using). Chill in fridge.

  • Caramelize the Onions: Slowly cook sliced onions in butter for 25–30 minutes until golden and soft.

  • Make the Buns (optional): Mix and knead all ingredients. Proof twice, shape into buns, egg wash, and bake at 375°F (190°C) for 15–18 minutes.

  • Cook the Fries: Bake or fry until crispy. Optional: add mashed potato layer. Top with cheese, caramelized onions, and sauce.

  • Cook the Patties: Form 4 thin patties. Season and sear 2–3 mins per side. Add cheese during final minute to melt.

  • Assemble Burgers: Toast buns in butter. Spread sauce, layer lettuce, tomato, patty, onions, and top bun.

 

  • Serve: Plate burgers with animal fries and extra sauce on the side.

Notes

  • For that true “smashed” burger style, press the patties flat while cooking.

  • Buns can be store-bought for a quicker version.

  • Keep extra sauce in the fridge for dipping or future use (lasts 5–7 days).
