  • 1 bag frozen fries
  • 1 tbsp olive oil
  • 2 onions, diced
  • 3/4 cup shredded cheddar cheese

Special sauce

  • 1/2 cup mayo
  • 2 tbsp ketchup
  • 2 tbsp relish
  • 1 tbsp dried minced onion
  • 1 tsp vinegar
  • 1 dash cayenne pepper


  • Preheat oven to 450 F. Add frozen fries to a parchment-lined sheet pan and bake according to package instructions (usually 10-12 minutes per side).
  • Meanwhile, dice onions and fry in a pan with olive oil for 20 minutes until onions slightly caramelize. Then, grate cheese and mix sauce ingredients together.
  • Remove fries from the oven about 5 minutes before the end of cook time, and add cheese. Bake remaining 5 minutes until fully melted.
  • Remove from oven and top with caramelized onions and special sauce. Serve and enjoy!



Try using different kinds of fries like waffle fries, curly fries or even sweet potato fries.
Lighten the calories by swapping out the mayo for sour cream or Greek yogurt and using half the amount of cheese and sauce.
Store any leftover fries and sauce separately in the fridge for up to 3 days. Reheat in the oven for 10-15 minutes at 350° Fahrenheit.
