Wagyu Smash Burgers with Tallow Onions

September 24, 2026 · 1 min read

Wagyu burgers are juicy enough to smash thin without drying out. The lacy, crispy edges are the whole point.

Makes 4 burgers

  • 1 pack Wa Wagyu Half-Pound Burgers (2 patties), each cut in half and rolled into balls
  • 1 tbsp Wa Wagyu Tallow
  • 1 onion, very thinly sliced
  • 4 slices American cheese
  • 4 potato buns, toasted
  • Pickles, mustard and your favorite sauce
  1. Melt the tallow in a cast-iron pan over medium heat. Cook the onions low and slow until soft and golden, about 15 minutes. Set aside.
  2. Turn the heat to high. Place 2 beef balls in the pan and smash flat with a sturdy spatula. Season with salt and pepper.
  3. Cook 2 minutes until the edges are brown and crispy. Flip, top with cheese and onions, and cook 1 minute more.
  4. Build on toasted buns and serve right away.
