Meal Prep for Beginners: A Week of Lunches (Australian Guide)

Meal prep sounds like a lot of work until you try it. Spend an hour or two on the weekend, and for the rest of the week lunch is already sorted. You'll spend less on takeaway and throw out less food. This beginner's guide walks you through planning, batch cooking, portioning and storing a week of lunches, following Australian food safety guidance.

Why meal prep lunches?

Lunch is the meal most of us leave to chance. Prepping ahead means you:

• save money compared with buying lunch most days
• use up groceries before they go off, so less goes in the bin
• eat more balanced meals, because the decision is made before you're hungry
• get back time on busy weekday mornings

Step 1: Plan before you shop

Start small. For your first week, pick two main recipes and alternate them, rather than five different dishes. Good beginner options cook in one pot or tray and reheat well:

• a chicken, vegetable and rice tray bake
• a beef or lentil chilli
• a vegetable and chickpea curry
• a pasta bake with a tomato and vegetable sauce

Write a short shopping list from those recipes and check the fridge and pantry first. Buying only what the plan needs is one of the easiest ways to cut food waste.

Step 2: Batch cook safely

Cook your recipes on Sunday (or whichever day suits you). The food safety step most beginners miss is cooling. Food Standards Australia New Zealand (FSANZ) advises cooling cooked food quickly, for example in shallow containers in the fridge, and keeping perishable food refrigerated at 5°C or colder. Bacteria can multiply quickly in the "temperature danger zone" between 5°C and 60°C (FSANZ, Food safety basics).

In practice:

• Don't leave a big pot cooling on the bench for hours. Divide food into smaller containers so it cools faster.
• Once steam has stopped rising, put it in the fridge. Leave a little space between containers so cold air can circulate.
• Check your fridge temperature with a fridge thermometer. It should read 5°C or below.

FSANZ also gives a simple 2-hour / 4-hour rule for perishable food left out at room temperature: under 2 hours, you can put it back in the fridge; between 2 and 4 hours, eat it straight away; after 4 hours, throw it away.

Step 3: Portion by container size

Choosing the right container makes prepping and reheating easier. As a rough guide:

• 470ml: sides, salads, snacks, sauces or a smaller lunch
• 800ml: a standard single lunch, such as curry and rice or a pasta bake portion
• 1.4L: two portions, or a larger salad base to split across days
• 2.7L: bulk cooked grains, chopped vegetables or a whole batch of chilli before portioning

Those are the four sizes in the Vuumex Glass Vacuum Food Container Set. The containers are borosilicate glass, so you can see what's inside at a glance. Each lid has a date dial to help you keep track of when food was made. Remove the lid before heating the container in the microwave or oven.

Step 4: Fridge for the first days, freezer for the rest

This is the most important rule for a week of lunches. The Food Safety Information Council advises storing perishable leftovers in the fridge and using them within two to three days (Food Safety Information Council, Leftovers). Five days of cooked lunches shouldn't all go in the fridge on Sunday night. The NSW Food Authority is stricter on cooked rice and pasta: eat them within 2 days (NSW Food Authority, Leftovers). For more detail, see our guides How long do leftovers last in the fridge? and How to freeze leftovers safely.

A simple beginner schedule:

• Monday to Wednesday: keep these portions in the fridge.
• Thursday and Friday: freeze these portions on the day you cook them. Move Thursday's lunch to the fridge on Wednesday night, and Friday's on Thursday night, so they thaw in the fridge.

Don't thaw frozen meals on the bench. FSANZ advises thawing frozen food in the fridge or using a microwave. Whatever the container, these times stay the same. Vacuum sealing helps limit air exposure, but it doesn't replace refrigeration or extend official storage times.

Reheating

Reheat lunches quickly until they're steaming hot all the way through. The Food Safety Information Council recommends at least 75°C in the centre, which you can check with a food thermometer. Stir halfway through microwaving to avoid cold spots, and only reheat each portion once.

A sample week of lunches

Here's how two recipes can cover five workdays without getting boring:

• Monday: chicken and vegetable tray bake with rice (fridge)
• Tuesday: lentil chilli with rice and a side of chopped salad (fridge)
• Wednesday: tray bake chicken and vegetables wrapped in a tortilla with salad, no rice (fridge)
• Thursday: lentil chilli, thawed overnight in the fridge (frozen on Sunday)
• Friday: chicken tray bake with rice, thawed overnight in the fridge (frozen on Sunday)

Keep salad leaves, dressings and crunchy toppings in a separate small container and add them on the day, so they don't go soggy.

Beginner tips

• Label everything. Write the date on frozen meals, or set the lid's date dial, so you're not guessing.
• Rotate. Put newer containers behind older ones so you eat the oldest first.
• Cook grains in bulk. Rice, quinoa and pasta make an easy base for different toppings. Cool and refrigerate cooked rice promptly, eat it within 2 days, and freeze any rice meant for later in the week.
• Pack it cold. Use an insulated lunch bag with an ice brick, and get your lunch into the work fridge as soon as you arrive.
• If in doubt, throw it out. If you can't remember when something was made, don't risk it.

Gear that makes meal prep easier

You don't need much. A couple of trays, a large pot and a few good containers will get you started. Glass containers in a few different sizes make portioning simple (our glass vs plastic guide explains the trade-offs). If you already own Vuumex containers, a spare rechargeable vacuum pump is handy to keep at work or in a second kitchen.

Frequently asked questions

How long does meal prep last in the fridge?

The Food Safety Information Council advises using perishable leftovers within two to three days. For a full working week, freeze the later portions.

Can I meal prep for a whole week?

Yes. Refrigerate the first two or three days of meals and freeze the rest, then thaw each one in the fridge the night before.

Does vacuum sealing make meal prep last longer?

Don't go past official fridge storage times, whatever container you use. Vacuum containers help limit air exposure and keep food organised, but you should still follow the guidance above.

Ready to start? Pick two recipes, set aside a couple of hours this weekend and give it a go. Next week's lunches will thank you.
