How Much Food Should You Store for an Emergency?
Ready.gov's floor is a 3-day supply of non-perishable food per person — food needing no refrigeration, cooking, or added water — with a 2-week supply as the stronger, still-official target where you have the storage space, mirroring the water guidance exactly.
The one thing to know: Freeze-dried pouches cost roughly 3-6x more per calorie than canned goods but weigh a fraction as much and keep for 25-30 years vs. 2-5 years for canned; canned food needs zero water to eat, freeze-dried needs hot water and a heat source. For a stay-at-home two-week kit, canned/dry staples are the practical, cheapest choice; freeze-dried earns its price mainly for bug-out weight or very long-dated storage.
What the guidance actually says
Ready.gov's Food page sets the 3-day minimum of non-perishable, no-cook food as the kit baseline, and the 2-week supply appears as the better at-home benchmark — the same structure state "Two Weeks Ready" campaigns use for longer utility or supply-chain disruptions. It parallels the water numbers: 3 days is the kit floor, 2 weeks is the at-home target.
What qualifies as emergency food
- Canned goods — proteins, vegetables, fruit; edible cold, straight from the can.
- Dry mixes and shelf-stable staples — no refrigeration or cooking required.
- A manual can opener — explicitly on ready.gov's checklist; it's the two-dollar item that defeats an entire canned supply if it's missing.
The full cost-per-calorie and shelf-life comparison between the two main formats is in our freeze-dried vs. canned breakdown — the short version is that canned/dry staples are the practical choice for a stay-at-home supply, and freeze-dried earns its price mainly for portability and decades-long storage.
Rotation: the part everyone skips
Canned shelf life runs roughly 2-5 years, so a supply bought once and never touched will silently expire. Fold it into your semiannual kit check: move anything approaching its date into normal pantry use and restock, the same visit where you rotate self-filled water and test batteries.
Food picks that fit the guidance
Research-based picks (how we evaluate) — live Amazon search links, no prices or ratings, an honest drawback on each.
ReadyWise 3-Day Emergency Food Supply Bucket (Freeze-Dried)
Freeze-dried entrees, ~25-year shelf life claim, requires hot water to prepare
Long shelf life and light weight make it a strong bug-out-bag or long-term-storage choice versus rotating canned goods.
Best for: The portable or very-long-term slice of a food plan, not the cheapest way to hit a 2-week at-home supply
Watch out: Needs potable water and a way to heat it — useless without your water and heat plan already in place, and it costs several times more per calorie than canned staples.
Check price on AmazonVarious (search current listings) Canned Food Variety Case (Shelf-Stable Staples)
Canned proteins/vegetables/fruit, no water or cooking needed, 2-5 year shelf life
The cheapest realistic way to build the ready.gov 3-day-to-2-week food supply, and it's edible cold straight from the can.
Best for: The bulk of an at-home 2-week food supply on a budget
Watch out: Heavier and bulkier per calorie than freeze-dried, and shelf life is shorter (2-5 years, not decades) — rotate into your regular pantry use and restock, don't let it sit untouched for a decade.
Check price on AmazonOXO Manual Can Opener (Heavy-Duty)
Manual, non-electric, ergonomic handle
Explicitly named on ready.gov's supply checklist — an all-canned food supply is useless in a power outage without one.
Best for: Every kit that includes any canned food
Watch out: Keep more than one — it's a two-dollar item that, if forgotten or lost, defeats an entire food supply.

Ready.gov's minimum is a 3-day supply of non-perishable food per person, with a 2-week supply as the stronger, still-official target where storage allows — the same 3-day-minimum, 2-week-better structure as the water guidance.
Non-perishable food that needs no refrigeration, cooking, or added water: canned goods, dry mixes, and shelf-stable staples. Include a manual can opener — an all-canned supply is useless in an outage without one.
For an at-home supply, usually not: canned food is far cheaper per calorie, needs zero water, and is edible cold. Freeze-dried earns its premium mainly for bug-out weight or very long-dated storage — it keeps 25-30 years vs. 2-5 for canned, but needs potable hot water to prepare.
Rotate it: at your semiannual kit check, move anything approaching its date into normal pantry use and restock. Canned shelf life runs roughly 2-5 years, so a stored supply that's never touched will silently expire.
Yes — both come from ready.gov guidance, and state 'Two Weeks Ready' emergency-management campaigns built on FEMA guidance use the same benchmark for longer utility or supply-chain disruptions.
