A 3-Month Food Supply on a Normal Grocery Budget

You don't need freeze-dried buckets to have three months of food. How to build a pantry a little at a time from the store you already shop at, what to buy, and how to rotate it.

A lot of people think a food supply means a pallet of freeze-dried buckets and a big credit card bill. It doesn't. The most practical food supply is a deep pantry of the normal food you already eat, built up a little at a time and eaten in rotation, so nothing goes to waste.

01Why three months

Three months covers most of the things that actually happen to families:

  • A job loss or a cut in hours.
  • An illness or injury that keeps you home.
  • Price spikes and shortages at the store.
  • A long winter storm or outage (with a way to cook).

You don't have to get there all at once. Start with two weeks, then a month, then three.

02Start with what you eat

The biggest mistake is buying food you don't normally eat. It sits on the shelf, expires, and gets thrown out.

  1. Write down a week of meals your family actually eats.
  2. Find the shelf-stable parts: pasta, rice, canned sauce, canned vegetables, beans, soups, peanut butter, cereal, oats, canned meat and fish, crackers.
  3. Multiply. If you eat spaghetti once a week, three months is about 12 boxes and 12 jars of sauce.

03Buy one extra

The simplest method: every time you shop, buy one or two extra of something on your list. When it's on sale, buy several. It adds a few dollars a week and builds up faster than you'd think.

Setting aside even $10 a week adds up over a year.

04What to stock

Staples:

  • Rice, pasta, oats, flour, cornmeal
  • Dried and canned beans
  • Peanut butter
  • Canned vegetables and fruit
  • Canned soups, stews and chili
  • Canned tuna, chicken, salmon, Spam
  • Cooking oil, salt, sugar, spices
  • Powdered or shelf-stable milk
  • Coffee, tea, drink mixes

Easy meals for days when cooking isn't possible:

  • Canned stew, chili, ravioli
  • Crackers, granola bars, nuts
  • Instant oatmeal

Don't forget:

  • Baby food and formula if you need it.
  • Pet food and supplies.
  • Foods for any special diets in the house.

05Rotate it

First in, first out. Put new cans at the back and pull from the front. Check dates every few months, and use anything close to expiring in a normal week's meals.

Most canned food stays safe well past the "best by" date if the can isn't swollen, rusted or dented badly, but quality slowly drops. Rotating keeps it fresh.

06Where to store it

Cool, dry and dark is best. A basement shelf, a closet, or under a bed works. Avoid hot garages and attics; heat shortens shelf life.

07Water and cooking

A food supply is only as good as your ability to use it:

08Keep it private

Don't advertise your pantry. When things get tight, people remember who said they had food. See the grey man.

A deep pantry is the quiet prep that pays off more often than any other. You'll use it during a sick week or a tight month long before any disaster.
