Start from recipes, not from the shop
The classic mistake is to walk through the store and hope that meals appear. A batch cooking list works the other way round: choose the recipes first, then derive everything else from them. It takes ten minutes and prevents most of the wasted food.
Step 1: choose recipes that overlap
Two or three recipes that share a few ingredients give you a short list. If one recipe uses half a cabbage, find another that uses the rest. If you buy a bunch of coriander, use it in two dishes. Overlap is the secret of a small, cheap list.
Step 2: calculate quantities for the whole batch
Recipes are written for a certain number of servings. Multiply the ingredient quantities by the number of portions you will actually eat. A common trap is to do it by eye and run out of rice halfway through the cooking.
Step 3: check your pantry first
Look in the cupboards, the fridge and the freezer. Oil, salt, spices, flour, rice and canned goods are often already there. Cross them off, and note the half-empty jars you will need.
Step 4: organize by aisle
Group the list: vegetables and fruit, meat and fish, dairy, dry goods, canned goods, spices. You will walk the store once, in order, instead of going back and forth. It also makes you less likely to be tempted by things that are not on the list.
Step 5: shop the day before
If you can, shop the day before your session. You wake up with the ingredients at hand, fresh produce is at its best, and you avoid the "I'll just go quickly" detour that eats an hour.
Tips to cut waste further
- Use the fragile things first. Fresh herbs, leafy greens and fish go in the first meals. Sturdy vegetables and grains can wait.
- Buy frozen when it makes sense. Frozen spinach, peas and berries are cheap and do not spoil.
- Keep scraps for stock. Onion peels, carrot ends and herb stems make a good broth.
- Check the freezer before buying more of the same.
A sample list (three recipes)
Imagine a chicken and rice dish, a lentil soup and a vegetable tray bake. The shared items are onions, carrots and garlic. The list is short: one pack of chicken, rice, red lentils, canned tomatoes, a bag of carrots, onions, a head of garlic, a bunch of parsley and a few spices. That is roughly twenty items for about a dozen meals.
