Article: Lay your tortillas out individually and sprinkle, spray, or brush both sides with enough water to coat. When tortillas dry out and get stale they lack moisture, and replacing it when you reheat them will make them soft again. Or, if you prefer a slightly longer cooking time, heat your oven to 350 F (177 C). Stack between five and eight tortillas on top of one another and wrap the stack in foil. Make multiple stacks if you require more tortillas. Bake the wrapped stacks in the oven for 10 to 15 minutes. For an oven that was heated to 350 F, heat the tortillas for 15 to 20 minutes.
