Why Flat-Freezing Saves Space Over Rigid Tubs

A rigid container takes up its full 3D shape in the freezer whether it is full or half-empty, and stacking odd-shaped tubs wastes space between them. A flat-frozen bag is roughly 2-3cm thick once solid, and stacks like a book, fitting far more portions into the same freezer drawer.

Flat portions also defrost faster, since there is less thickness for heat to travel through, which matters on a weeknight when you forgot to move a portion to the fridge the night before.

Reusable Silicone Vs Disposable Freezer Bags

Reusable silicone bags cost more upfront but pay for themselves after a few months of regular use, and hold up better to repeated freezing and washing than thin disposable bags. Disposable freezer bags are still a reasonable choice for occasional use or for food you are not confident about reusing a bag for, such as raw meat marinades.

How To Flat-Freeze Without Spills

Fill the bag no more than two-thirds full to leave room for expansion, seal it, then lay it flat on a tray in the freezer rather than standing it upright until it is solid. Once frozen solid, the tray is no longer needed and portions can be stacked directly.

1. Fill the bag two-thirds full, leaving headspace
2. Push out excess air before sealing
3. Lay flat on a tray or baking sheet
4. Freeze flat until solid (usually a few hours)
5. Once solid, remove the tray and stack portions directly

What Freezes Well In A Bag Vs What Needs A Rigid Container

Soups, sauces, mince-based dishes, curries and stews all flat-freeze well in a bag. Delicate foods that could get crushed under stacked weight, or dishes with a lot of solid chunks that would be awkward to defrost through a narrow bag opening, are usually better suited to a rigid container instead.
