It's best to eat taquitos immediately after they are cooked while they are still hot and crispy. If you have leftovers, you can store them in an airtight container in the refrigerator for up to 3 days. To reheat, place the taquitos in a single layer on a baking sheet and bake in a preheated oven at 350°F for 5-10 minutes or until they are hot and crispy again.
