Start before you shop
Most food waste is decided before you cook, at the store. Shopping without a plan leads to duplicate buys and produce that rots before you get to it. A quick check of what you already have, a loose meal plan, and a realistic list prevent the over-buying that fills bins. Buying a little more often, rather than one enormous haul, also keeps perishables fresh.
Being honest about how much you will actually cook in a week is the single most effective anti-waste habit.
Cook flexibly and use leftovers
Learn a few 'clean out the fridge' formats that absorb odds and ends: frittatas, fried rice, soups, stir-fries, grain bowls, and pasta bakes will happily take whatever vegetables and proteins need using. Treat leftovers as a head start rather than a chore — roast extra vegetables to become tomorrow's soup, or cook once and repurpose across two meals.
Keep an 'eat me first' zone in the fridge and do a weekly sweep to catch things before they turn.
Rescue and preserve
Wilting herbs become pesto; overripe fruit becomes smoothies, compote, or baking; stale bread becomes croutons, breadcrumbs, or panzanella; vegetable scraps become stock. Freezing is your ally — portion and freeze anything you cannot use in time. Quick pickling extends the life of vegetables while adding flavor.
None of this requires special skill, just the habit of asking 'how can I use this?' before 'should I toss this?' The savings, over a year, are substantial.
