Peel and grate the Russet potatoes using a box grater or food processor.
Rinse the grated potatoes under cold water to remove excess starch.
Pat them dry with a clean towel.
Heat vegetable oil and butter in a large skillet over medium heat.
Make sure the pan is evenly coated with the mixture.
Spread the grated potatoes evenly in the skillet.
Season them with salt and black pepper to taste, ensuring an even distribution.
Cook the potatoes on one side for about 5-7 minutes or until golden brown.
Flip them gently using a spatula and cook for another 5 minutes.
Once both sides are crispy, remove the hash browns from the skillet.
Drain any excess oil by placing them on paper towels before serving.
