Ingredients
  

Smash burger patties + assembly
  • 1 lb ground beef (80/20 blend)
  • 0.5 onion, thinly sliced
  • 8 corn tortillas or small flour tortillas
  • 4 American cheese slices
  • Vegetable oil
  • Pickles, shredded lettuce, diced onion for toppings
Big Mac sauce
  • 0.5 cup mayonnaise
  • 2 tbsp ketchup
  • 1 tbsp relish
  • 1 tsp mustard
  • 1 tsp paprika
  • salt
  • pepper

Equipment

  • 1 cast iron skillet

Method
 

Make the Big Mac sauce
  1. Whisk mayonnaise, ketchup, relish, mustard, and paprika with salt and pepper until smooth.
Smash and melt the patties
  1. Heat a cast-iron skillet over high heat until very hot.
  2. Form the ground beef into 8 thin patties.
  3. Cook the patties in batches, pressing down hard with a spatula for 1-2 minutes per side until the edges are crispy.
  4. Top 4 patties with American cheese and let it melt.
Warm tortillas and assemble the tacos
  1. Warm the corn tortillas or small flour tortillas.
  2. Spread Big Mac sauce on each tortilla.
  3. Layer with a smashed patty, pickles, shredded lettuce, and diced onion for toppings.
  4. Top with another patty if desired and serve immediately.

Notes

Pro tip: press the patties firmly during cooking to build a crisp, lacy edge. Store leftovers covered in the fridge up to 2 days; reheat patties in a hot skillet to re-crisp. Freezing is not recommended for best texture. For a lighter option, use 90% lean ground beef to reduce fat while keeping the smash technique the same.
