Equipment

  • 1 | Parchment paper | for smashing

Ingredients
  

  • 1 | lb | frozen french fries |
  • 1 | lb | ground beef | 80/20 preferred
  • 1 | tsp | salt |
  • 1/2 | tsp | black pepper |
  • 2 | tbsp | neutral oil |
  • 1 | cup | shredded cheddar cheese |
  • 1/2 | cup | milk |
  • 1 | tbsp | butter |

  • 1/4 | cup | burger sauce or mayo | optional

Instructions
 

  • Cook frozen fries according to package directions until deep golden and crisp.
  • Season ground beef with salt and pepper, then divide into four loose balls.
  • Heat oil in a large skillet over medium-high heat until shimmering.
  • Place beef balls in the pan, cover with parchment, and smash firmly with a spatula.
  • Cook 2 minutes until edges are crispy, flip, cook 1 more minute, then break into pieces.
  • Melt butter in a saucepan, whisk in milk and cheddar until smooth cheese sauce forms.
  • Arrange hot fries in a dish, top with smashed beef pieces, and pour cheese sauce over.
  • Sprinkle with crispy fried onions and drizzle with burger sauce if using. Serve immediately.
  • Tip: Press the beef hard for maximum crispy edges.

Notes

Store leftovers in an airtight container in the fridge for up to 2 days.
Reheat in a 375°F oven to restore crispness rather than microwaving.
Swap ground beef for turkey if preferred for a lighter version.
Make the cheese sauce ahead and reheat gently with a splash of milk.
