Everyone has that moment when your eyes are bigger than your stomach and you over-order your favorite tacos from Taco Bell Or, perhaps, you just don't have time to cook, so you order enough food to last for awhile. Refresh and rewarm that fast food and make it taste almost like new the next day.
Remove tacos from foil or foil-lined wrappers.
Put fresh produce and toppings aside. Fresh produce includes lettuce, tomatoes, and onions; toppings might include grated cheese, sour cream and guacamole.
Remove meat, beans and other main ingredients, set aside.
Warm and crisp taco shells in the oven, if possible. Leftover taco shells often absorb moisture from other ingredients overnight and get soggy. Place empty taco shells on a cookie sheet in a 375 degree oven for 10 to 15 minutes to dry. You can also dry them in a microwave for 20 to 30 seconds, or warm them in a frying pan over medium-high for 2 to 3 minutes per side.
Place meat in a non-reactive bowl or container and reheat main ingredients in the microwave for 30 seconds. You can also reheat main ingredients in the oven or in a pan on the stove. Be careful not to overcook or the protein will become dry and rubbery.
For soft tacos, you can also leave the taco shells with their main ingredients inside the foil wrappers and re-heat them in the oven. Space the tacos at least 1 inch apart on a cookie sheet and reheat in a 375 degree F oven for 10 to 15 minutes. Remove from the oven and check if the tacos are hot through the middle.
Once the taco shells are crisp and the meat or beans are hot again, reassemble the taco, placing the fresh produce and condiments on top.
Follow the same basic steps to reheat burritos, nachos, chalupas, and other dishes.
