Pour the ghee, butter, bacon fat or coconut oil over the potatoes and stir to coat.
Combine dry ingredients (garlic powder, onion powder, cumin, paprika, salt and pepper) in a small bowl.
Sprinkle the dry ingredients over the potatoes and stir until potatoes are coated with the seasoning mixture.
Spread the potatoes in a single layer on a baking sheet. (I use two standard size cookie sheets or one large sheet pan. Use a silicon baking mat to keep the potatoes from sticking.)
Bake for 25-30 minutes.
Serve with tortillas, cheese (Gouda is our fav!), and lettuce for potato tacos or top with over easy eggs or eat the potatoes alone.
Alternately, you can fry the potatoes in a skillet over medium heat until they are crispy on the outside and soft on the inside.
