1. Make the Potato Mixture
In a large mixing bowl, combine the mashed potatoes, shredded cheese, 1 egg, sour cream, salt, pepper, and garlic powder. Stir until a sticky but shapeable dough forms. If it’s too loose, add a bit of flour.

2. Shape the Sticks
On a floured surface, roll the dough into a rectangle about ½ inch thick. Use a sharp knife to cut into sticks about ¾ inch wide and 3–4 inches long. Place on a tray and chill in the fridge for at least 30 minutes.

3. Set Up Breading Station
Place flour in one shallow bowl, beat 2 eggs in another, and place breadcrumbs in a third.

4. Bread the Sticks
Coat each stick in flour, then dip in egg, and roll in breadcrumbs. For extra crunch, repeat the egg and breadcrumb step for a double coating.

5. Fry Until Golden
Heat 2 inches of oil in a deep pan to 350°F (175°C). Fry sticks in batches until golden brown, about 2–3 minutes per side. Remove and drain on paper towels.

6. Serve
Serve hot with your favorite dips: sour cream with chives, garlic mayo, or spicy paprika aioli.
