Freeze in glass, not plastic

For freezing multiple portions every Sunday, get 2–3 cup glass containers with snap-lock lids. They handle freezer temps without warping, go straight into the microwave or oven, and don’t absorb last week’s chili smell.

Plastic meal prep boxes are cheaper, but they’re the wrong tool for this. The kind that’s safe for the freezer tends to be stiff, brittle plastic that cracks after a few months. And the softer, flexible lids? Those turn into stained, warped messes. Glass just doesn’t care. It also stacks cleanly in a full freezer, which matters when you’re making six identical meals.

A couple of practical tips: get the square or rectangular ones, not round, so they pack tighter. Leave some headroom when you fill them because liquids expand when frozen. And don’t bother with divided bento boxes—separating components is a fragile game when the whole thing is a block of ice. The simple single-compartment style with a good seal is the workhorse.

One brand you can trust is Pyrex’s Snapware line, but the IKEA 365+ containers are honestly just as good for half the price.

Future-You on Tuesday afternoon deserves better than a cracked container full of freezer-burned soup.
