Food Storage and Meal Prep: Containers, Freezing and Cutting Waste

Food waste is a storage problem more often than a shopping problem. Most of it is bought with good intentions and thrown away because it was stored somewhere it could not be seen or in a way that let it spoil.

Containers worth owning

• One system, stacking, with interchangeable lids. Mismatched lids are the reason drawers become unusable.
• Glass for anything reheated or stored with strong flavours. It does not stain, hold smells or degrade, and goes from fridge to oven in many ranges.
• Plastic for the freezer and for carrying, since it is lighter and does not break. Check it is freezer-rated, as some plastics become brittle.
• Clear rather than opaque. Food you cannot see is food you will not eat.
• A small number of sizes, chosen to fit your shelves and your portions.

Check whether lids are microwave-safe separately from the container, and whether the seal is removable for cleaning, since that is where smells live.

Freezing properly

• Cool food before freezing, and freeze it while fresh rather than as a last resort on the day it turns.
• Freeze in portions you will actually use. A large block that must be thawed entirely gets used once.
• Flat is better than lumpy. Freezing liquids flat in bags makes them thaw far faster and stack better.
• Remove air. Freezer burn is dehydration caused by air contact.
• Label with contents and date. Unlabelled containers become mysteries and then waste.
• Leave headspace in anything liquid, which expands.

Thaw in the fridge rather than at room temperature, and use thawed food promptly.

Fridge organisation

Temperature is not uniform. The door is the warmest part and the least suitable for milk and eggs despite being designed for them. The back and bottom are coldest.

• Keep raw meat on the bottom shelf, contained, so nothing can drip onto other food.
• Keep a designated "use first" area at eye level. This one habit prevents a large share of waste.
• Do not over-pack it. Air needs to circulate.
• Check the temperature with a thermometer rather than trusting the dial.

Meal prep that survives contact with the week

Prepping components rather than complete identical meals works better for most people — cooked grains, roasted vegetables, a protein, a sauce. You keep the flexibility and avoid the fifth consecutive identical lunch, which is why most meal prep stops.

Be realistic about how long things keep. Prepping five days ahead on a Sunday means eating something on Friday that was cooked six days earlier.

Before you order

Measure your shelf and drawer space before buying a container set. Check that lids are compatible across sizes. Check freezer, microwave and dishwasher ratings separately for container and lid. And check whether replacement lids and seals are sold, since losing a lid should not retire a container.
