Yes. Anecdotal sources suggest that you may try for a few seconds (about 30 seconds in a microwave to get them warm) and then 3 minutes in a pan on the stove to get them crispy.
According to Livestrong.com, preparing frozen toaster strudels in the microwave oven is not a good choice. Because the product is frozen and would be heated quickly in the microwave, the cooking of the pastry would be uneven. Some portions, such as the crust, may remain cold and soggy, while other components, such as the fruit filling, might become scorchingly hot.
The flaky, buttery, fruit-and-nut-filled roulades are in high demand and come under intense scrutiny. To be the very best, the strudel (which means ‘whirlpool’ in German, thanks to its distinctive rolled shape) must be made from scratch, which means hand-stretching soft dough into a paper-thin sheet the size of a tabletop.
