The short answer

Meal prep simply means preparing some food ahead of time so that good meals are easy to put together during the week. For beginners, the easiest approach is to cook a few building blocks, such as a protein, a grain and some roasted vegetables, and mix them into different meals, rather than cooking five identical boxed lunches. Start with two or three days of lunches, store food safely, and build from there.

Why meal prep helps

Step 1: Start small

You do not need to prepare every meal for the week. A good first goal is three lunches, or breakfasts for the working week. Once that feels easy, add more.

Step 2: Plan a few building blocks

Pick one or two items from each group and cook them in a batch:

With these in the fridge, you can make a grain bowl one day, a wrap the next and a quick stir-fry after that, all from the same ingredients.

Step 3: Cook efficiently

A typical beginner session might take around 90 minutes:

  1. Start the grain or potatoes first, as they take longest.
  2. Put a tray of vegetables and a tray of protein in the oven at the same time.
  3. While those cook, boil eggs, chop salad vegetables and mix a dressing.
  4. Cool everything quickly, then portion into containers.

Step 4: Store food safely

Food safety is the most important part of meal prep. General guidance from food safety agencies includes:

General guidance. Advice varies by country; the UK Food Standards Agency suggests eating most leftovers within 2 days, and USDA guidance says 3 to 4 days.

Step 5: Keep it from getting boring

Eating the same meal five days in a row is the main reason people give up on meal prep. Some ways to keep it interesting:

Containers and kit

A set of reusable containers in a few sizes, a couple of large baking trays and a big pot are enough to start. Containers with separate compartments help keep sauces and crunchy foods apart. Glass containers are easy to reheat in, while lighter plastic ones are easier to carry.

Meal prep and your goals

Meal prep makes it easier to eat balanced meals and keep portions consistent. If you are focused on protein, cooking a batch of chicken or tofu at the start of the week helps a lot; our guide to protein in chicken breast has the numbers. If you are working toward weight loss without detailed tracking, prepared meals make it easier to follow the habits in our guide to losing weight without counting everything.

Frequently asked questions

How long does meal prep last in the fridge?

Most cooked meals keep for a few days in a fridge at 5°C or below. The UK Food Standards Agency suggests eating leftovers within 2 days, and USDA guidance says 3 to 4 days. Cooked rice should be eaten within 24 hours. Freeze anything you will not eat in time.

What is the easiest meal to prep for beginners?

A simple grain bowl is a good start: a batch of rice or quinoa, a tray of roasted vegetables, a cooked protein such as chicken or tofu, and a dressing. You can combine them differently each day.

Is it safe to reheat meal prep?

Yes, if it was cooled and stored properly. Reheat until steaming hot all the way through, and only reheat food once.
