1. Heat a large pan (the bigger the better) with oil.
2. Add panko crumbs and season with onion and garlic powder, if desired.
3. Fry until lightly browned, about eight minutes, stirring around every 30 to 45 seconds. You may need to add oil to prevent them from burning.
4. Drain on paper towels and let cool. Store in an airtight container.
Variations: Instead of frying, bake it in an oven by mixing panko with oil and baking at 350 degrees Fahrenheit for eight to 12 minutes until light golden brown, stirring every two minutes. (This method is probably easier.)
