Notes

  • To flatten patties into thin, circular patties, use a burger press or a large flat spatula. Alternatively, you can use your hands to flatten patties into desired thinness. 
  • Cook patties in batches if pan/skillet is not large enough. Avoid overcrowding the pan so that patties can cook properly. 
  • I highly recommend you use my Homemade Brioche Buns Recipe and In-N-Out Animal Style Fries Recipe with this burger recipe.
