How to make grandma-style french fries?


  • 4 medium Russet or Idaho potatoes per person
  • Vegetable oil for frying
  • Salt to taste


  1. Gather the potatoes according to the individual serving size. We are working with 4 medium potatoes per person. Peel the potatoes and wash them under cold running water to get rid of all the dirt.
  1. Cut the potatoes into 4-5 vertical slices. Cut each slice into 4 sticks. Make sure the size of the sticks and slices are consistent. 
  1. Soak the potatoes in cold water for about 25-30 minutes. This will remove the excess starch off the surface of potato sticks. 
  1. When the soaking time is up, strain the potato sticks and spread them onto a baking tray lined with clean towels or paper towels.
  1. Heat a few inches of oil in a heavy pot to 350F. Use a thermometer to accurately gauge the temperature of the oil.
  1. Fry the potatoes in hot oil in small batches. Do not overcrowd the pot as it will lead to uneven frying.
  1. Transfer the fries from the hot oil onto paper towels to get rid of the excess oil. Season the fries with salt. Serve and enjoy.
