Short answer: pre-chill your cooler, use frozen water bottles or block ice instead of loose cubes, pack frozen food at the bottom, keep the cooler in the shade, and open it as little as possible. Keep perishable food at 40°F or below, and eat the most perishable meals first.
Here's how to keep food cold and safe for a weekend of camping.
1. Pre-chill the cooler
A warm cooler melts your first load of ice. The night before, put a frozen jug or a bag of ice inside, or keep the cooler indoors instead of in a hot garage.
2. Use bigger ice
Block ice and frozen water bottles melt much more slowly than cubes. Frozen bottles have a second job too: once they thaw, they're drinking water, and there's no puddle in the bottom of the cooler.
3. Freeze what you can
Freeze meat, stews and sauces flat in zip bags. They act as extra ice and thaw in time for the second or third day's meals.
4. Pack in layers
- Bottom: frozen food and block ice.
- Middle: raw meat in sealed bags, then dairy and eggs.
- Top: fruit, vegetables and the things you'll grab first.
Fill empty space with ice or a towel. Air warms up faster than packed food.
5. Use two coolers if you can
Drinks get opened all day. Food doesn't need to. Keep drinks in one cooler and food in another, so the food cooler stays closed and cold.
A soft cooler works well for drinks and lunch on day trips. Our 32L Soft Cooler Bag ($50.99) has an insulated hard liner, side mesh pockets and a shoulder strap, and it folds flat when you get home. For long trips in hot weather, pair it with a hard cooler for the food.
6. Keep it in the shade and off the ground
Direct sun heats a cooler fast. Park it under the table or a tarp, and put it on a mat or a log instead of hot dirt or sand. Throw a blanket or sleeping bag over it on hot afternoons.
7. Open it less
Plan what you need before you open the lid, grab it, and close it. Keep a list of what's inside taped to the lid.
8. Plan meals in the right order
Eat the most perishable food first: fresh meat and fish on day one, frozen meals on day two, then shelf-stable food like pasta, canned beans and tortillas for the last day.
Food safety basics
- Keep perishable food at 40°F or below. A small fridge thermometer in the cooler takes the guessing out of it.
- Throw out perishable food that has been above 40°F for more than 2 hours (1 hour in very hot weather).
- Keep raw meat sealed and below other food so it can't drip.
- When in doubt, throw it out.
FAQ
How long will ice last in a cooler when camping?
It depends on the cooler, the weather and how often you open it. Pre-chilling, block ice, shade and opening it less all make ice last longer. Top up ice at a camp store if you can.
Should I drain the water from my cooler?
Cold meltwater helps keep things cold, but it also soaks food. Keep food in sealed bags or containers, and drain the water if it starts to warm up.
Is a soft cooler good for camping?
Soft coolers are light and easy to carry, and they work well for drinks, day trips and short weekends. For several hot days, a hard cooler holds ice longer.
