The half onion, the last two potatoes, the cooked rice from Tuesday — individually they are not a meal. Together, with the right approach, they often are.
The secret is a few forgiving formats that work with whatever you have.
The everything formats
- Frittata or omelette: eggs plus any cooked veg, cheese, or meat
- Fried rice: day-old rice, any veg, soy sauce, an egg
- Soup: softened veg, stock, a blender
- Pasta bake: cooked pasta, sauce, odds and ends, cheese on top
- Wraps and quesadillas: leftover fillings, a tortilla, a hot pan
Plan a leftovers night
Make one evening a week a fridge-clearing night. Lay everything out, decide what needs eating first, and choose a format. It saves money and stops forgotten tubs ending up in the bin.
Safety rules
Cool leftovers quickly and refrigerate within about two hours. Eat refrigerated leftovers within a few days, and reheat until piping hot all the way through. Cooked rice needs particular care: cool it quickly and reheat only once.
Freeze before it is too late
If you will not get to something within a day or two, freeze it. Label tubs with the contents and date. Bread, cooked grains, sauces, grated cheese, and chopped herbs in oil all freeze well.
