Cook Once, Eat Twice: Save Time and Reduce Food Waste

This blog post outlines the golden rule of student cooking that you should start following straight away: cook once, eat twice! This is a really simple rule that saves you time, money, avoids decision fatigue (where your daily productivity is reduced by the fatigue caused from spending time making decisions!) and helps you eat a healthy balanced diet.

What the rule is:

When you’re cooking dinner, try to avoid only ever making a portion that feeds just one person. Cook portions that feed 2, 3 or 4 people – eating the leftover portions the next day or the day after that. Any additional portions can be frozen and eaten on a day you’re short on time or get home late. This rule of cooking once and eating it twice (or three, four times etc) means the food you cook for dinner can be eaten the following day for lunch – meaning you avoid having to prepare or buy lunch, reduces food waste by only using half of ingredients for one portion, and oftentimes, food tastes even better when eaten the next day (particularly curries, stews and the like!). Lots of food can taste great cold too, or the main base of a meal can be eaten in a different way the next day to keep it interesting – such as using roasted veggies from a side dish for dinner, and turning it into the main ingredient in a pasta dish for lunch the next day.

Lots of our recipes on our website either cater for one individual or the serving size is listed. When reading recipes that you want to make for more or less people/portions, simply use a calculator and pen and paper to write the new ingredients list!


Another alternative to this rule is batch cooking. Batch cooking is when you spend time making a big batch of one meal and portioning it up into Tupperware to freeze and eat at a later date. We love making a big batch of our lentil Bolognese on a Sunday evening, freezing it in portions and taking it out of the freezer the night before to eat for dinner the following day. That way, when we get home late or tired from the library, we simply just have to reheat it with some pasta, rice or potatoes to make a filling wholesome meal. It cuts down cooking time in the kitchen, uses less washing up and less space on kitchen amenities when lots of housemates are cooking at the same time.
