Prep the Potatoes. Start by grating your potatoes. For extra crispy hash browns, rinse the grated potatoes under cold water to remove excess starch, then squeeze out as much moisture as possible using a kitchen towel.
Season. Toss the dried, grated potatoes in a bowl with salt and pepper.
Cook to Perfection. Heat a mixture of butter and olive oil in a skillet over medium-high heat. Spread the potatoes in a thin layer, pressing down lightly. Cook until the underside is golden brown and crispy for 5-6 minutes, then flip and repeat.
Serve and Enjoy. Transfer your crispy hash browns to a plate. For an extra touch, sprinkle with fresh herbs like parsley or chives.
