If you find you've cooked too much spaghetti and sauce, you can store it to use it later. Saving the surplus will lower your food bill and provide you with a satisfying meal anytime you like. Before serving your stored spaghetti and sauce as another meal you must heat it to a temperature of at least 74C to kill off all harmful bacteria.
Place the sauce and spaghetti in an ovenproof dish. Preheat the oven to 180C. Sprinkle Parmesan or mozzarella cheese on the spaghetti. Cover the dish tightly with aluminium foil. Heat it for 15 to 20 minutes.
Place the spaghetti and sauce in a microwave safe dish. Add 1 teaspoon of water to the food. Cover the food loosely with cling film. Heat for one minute intervals until the food is thoroughly heated.
Pour the spaghetti and sauce into a saucepan. Add a tablespoon of water to the pan if the sauce is thick. Heat the food on a low heat for 5 to 10 minutes, stirring occasionally to keep food from scorching.
If unsure about the internal temperature of the food, use a food thermometer before eating.
