There are many ways to reheat a cooked gluten free dosa. 1) Air fry dosa at 375 degrees F (190 degrees C) for approximately 2 to 3 minutes or heated through and crispy. 2) Pan fry on medium heat for 1 to 2 minutes on each side until the dosa is warm and crispy. 3) Bake at 375 degrees F (190 degrees C) dosa in a single layer for 2 – 3 minutes. Turn halfway in the heating process. Do not cover. 4) The microwave method is our least favorite way to reheat a dosa. It makes the instant rice flour dosa soggy. However, it will be warm in 30 seconds to 45 seconds on high power.
