Meal prep – cook once and freeze meals in portions

Weeknight rush usually is not caused by cooking being difficult, but by cooking landing in the busiest part of the day. Meal prep moves the work to a moment when you do have time: you cook a bigger amount at once and divide it into portions for the fridge and the freezer. On a busy evening you reheat a ready portion instead of starting from scratch.

What meal prep means in practice

This is not about spending the whole Sunday in the kitchen. One proper stew, soup or bake plus one large batch of a base – cooked barley, roasted root vegetables or a tomato sauce – is enough to change the rhythm of the week. Two one-hour sessions a month build a freezer selection that solves a weeknight in ten minutes.

Choose dishes that keep well

Not every dish suits this. Soups, puréed soups, stews, chillies, mince sauces, lentil and bean dishes, curry sauces and oven bakes work best. They often even improve as the flavours settle overnight. Cooked pasta, crispy fried food and fresh salads are better made at the moment of eating – they are quick anyway.

Cool it quickly, that is the key step

A big pot of food cools slowly, and slow cooling is the risky point for food safety. The Finnish Food Authority's home-kitchen advice is simple: divide the food into smaller containers or a shallower layer so it cools clearly faster, and speed cooling up by standing the container briefly in cold water. Do not put food into the fridge while it is still warm, but do not leave it at room temperature for long either. Keep the fridge cold, below +6 °C, and the freezer at −18 °C.

Pack in portions, not one block

Freeze food in the portions you actually eat: a lunch portion for one, dinner for two, a child's portion. One large solid block thaws slowly and forces you to reheat everything at once. Leave a little air space in the container, because liquid expands as it freezes, and label every container with contents and date. Without labels the freezer becomes a guessing game within weeks.

What freezes well – and what does not

Soups, sauces, stews, mince dishes, lentil and bean dishes and most oven bakes freeze well. Soups with potato easily turn mealy, cream sauces may split, and fresh vegetables, cucumber and leafy salad do not belong in the freezer at all. A trick: freeze the sauce or stew on its own and cook the pasta, rice or potatoes on the day you eat – the result is then close to freshly made.

Thawing and reheating

The safest way to thaw is to move the portion into the fridge the evening before. Thawing at room temperature keeps food too long at temperatures where bacteria multiply. Reheat thawed food properly hot all the way through, not just lukewarm, and stir during reheating so the middle heats too. Reheat only the portion you are going to eat, and do not refreeze food that has already been thawed.

How to start this weekend

Do not try to fill the whole freezer at once. Pick one recipe, double it and freeze half – that is plenty for a first try. A puréed soup is a good start, because it takes freezing particularly well and reheats fast. For example Cheesy Vegetable Purée Soup & Rye Bread works well doubled, if you leave the bread for the moment of serving.
