How to Reduce Food Waste When Cooking for One
TL;DR: Cooking for one wastes food less because of poor planning and more because most groceries come sized for two to four people. These are specific tactics, not general advice, for closing that gap: freezing in true single portions, buying in the shape you'll actually finish, and choosing meals that share an ingredient instead of each opening a new one.
Cook in multiples, freeze in singles
Cook a full batch, but don't store the whole batch in the fridge hoping to work through it. Roast a full tray of vegetables or make a full pot of rice, eat what you'll actually get to within a couple of days, and freeze the rest immediately in single portions. The freezer stops the clock; the fridge doesn't.
Buy in the shape you'll actually finish
Two approaches both work. Buy smaller package sizes, even if the unit price is worse, since a slightly higher cost per gram beats throwing half of it away. Or buy the standard size and process it the day you get home: chop and freeze the extra onion, portion ground meat into single servings before it goes in the fridge, not after it's already turning.
Let one ingredient anchor two or three meals
Rather than picking three unrelated recipes that each open a new item, choose meals that share a perishable ingredient reaching its use-by date around the same time. One bunch of herbs, one carton of cream, one bag of greens, used across the week instead of opened once for a single dish and forgotten.
Know what actually holds up alone
Some things last fine for one person over a week: root vegetables, hard cheese, cured meats, anything already frozen. Others don't: leafy greens, fresh herbs, pre-cut produce. Shopping as if everything has the same shelf life is what causes most of the waste in a single-person fridge, not a lack of planning.
Where FridgeAI fits
Same mechanic as the general version of this page, aimed at the specific problem of cooking for one: photograph what's in the fridge, and get a recipe that uses the ingredient closest to turning, rather than tracking expiry dates in your head for a household of one.
