Deep-fried shrimp is a common food item, and though it is most popular in the southern United States, it is served throughout the world in diners, restaurants and home kitchens equipped with a deep fryer. However, reheating deep-fried shrimp that was crispy and succulent can be challenging, as batter tends to fall off and lose much of its crunch, while the shrimp has a tendency to dry out and become less moist. Deep-fried shrimp can be reheated, though, and much of the original quality can be retained using the proper heating method.
Preheat the oven to 177 degrees Celsius.
Place a sheet of waxed paper inside a roasting pan with thick walls. The waxed paper should be a bit smaller on all sides than the roasting pan. This will keep excess oil used to fry the food initially from being reabsorbed as the shrimp gets hot, which can make them soggy and fall apart easily.
Place the deep-fried shrimp on top of the waxed paper, leaving about 1/2 inch of space between each piece to keep them from sticking as they warm.
Put the roasting pan in the oven for 15 minutes and allow the shrimp to reheat with the oven door closed.
Remove the shrimp from the oven and eat, or cut one in half to test its warmth. If the shrimp are particularly large or have a thick batter coating, they may need to go back in the oven for an additional five to 10 minutes, depending on personal preference.
You can reheat other leftover items like French fries at the same time if they are of similar thickness. If you have particularly large shrimp and thin shoestring French fries, reheat the shrimp for 10 minutes before removing the roasting pan and adding other items. Do not dip the shrimp in sauce or liquid before reheating them in the oven. Liquids will cause the batter to become soggy and fall apart. Items like cocktail sauces or dipping sauces that are commonly served with fried shrimp can be reheated either on the stove in a small saucepan, or in the microwave in a microwave-safe container.
Avoid microwaving fried foods. Microwaves steam food, releasing moisture, which will cause the shrimp batter to break apart and crumble. Reheating steamed shrimp works well in the microwave, but fried foods do not fare well.
