McDonald's Mashed Potatoes

Emily Jacobs


  • McDonald's medium fries
  • 1 1/2 Pound  potatoes, peeled and diced into large chunks
  • stick butter
  • 1 Cup  whole milk
  • 1/2 Cup  sour cream
  •   Salt and pepper, to taste

Few can resist the salty crunch of a McDonald's fry, and what's better than enjoying them alongside a Big Mac? Having them on your Thanksgiving plate. This recipe gives a Thanksgiving classic — mashed potatoes — a face-lift with the notorious fried potato from the fast-food chain. 


Preheat the oven to 350 degrees.

On a cutting board, cut the fries into medium-sized, ½-inch chunks.

Place the puréed fries onto a baking sheet and bake in the oven for about 5 minutes, until crisp tender. Turn the heat down to 200 degrees and keep warm until ready to incorporate into the mashed potatoes.

Place the potatoes in a medium-sized saucepan filled with heavily salted water. Bring to a boil, and boil gently for 12 minutes until the potatoes are fork tender. Drain, and add to a food processor or blender. Add the butter, milk, and sour cream and purée until smooth. Season with salt and pepper.

Add the mashed potatoes to a bowl and slowly fold in the crisp puréed McDonald’s fries. Serve hot.
