Most fruits, vegetables, cooked meats, eggs, dairy and complete meals can be freeze dried, but foods that are very oily, very sugary or already dry generally cannot. Harvest Right says you can freeze dry almost anything, and its manual and Blue Alpine’s both list exceptions, such as chocolate, peanut butter, honey and jerky. This guide sorts foods into what works, what is hard, and what to skip, using the makers’ own lists, plus tips on slicing, loading and food safety. It is based on the manufacturers’ manuals and Utah State University Extension, not on our own testing.
Foods That Work Well
- Fruit. Blue Alpine’s manual says strawberries and bananas tend to freeze dry best when sliced between 3/16 and 1/2 inch (5-13 mm) thick. Utah State University Extension lists fruits and vegetables among the foods that work.
- Vegetables, grains and beans. Named by Utah State University Extension as good candidates.
- Herbs. Blue Alpine’s manual says herbs freeze dry well and are unlikely to collapse. For other ways to preserve them, see how to dry herbs.
- Eggs. According to the manual, eggs work best freeze dried raw, and the texture is unaffected when reconstituted.
- Meat. It freeze dries well raw or cooked, though the manual recommends cooking meat first for sanitation.
- Blended or watered-down foods. The manual says many difficult foods become much easier once blended and mixed with water.
Fresh food will freeze dry better than pre-frozen food from the store, according to Blue Alpine’s manual.
Foods That Are Hard or Messy
- Watermelon. Blue Alpine calls it one of the hardest foods to freeze dry and one of the wettest.
- Juices. They typically do not work as they are. The manual says that if watered down enough, it can be possible, with ratios of 1:4 or higher.
- Sugary fruits. Harvest Right’s manual says oranges, pineapple, strawberries, blueberries and other foods with a lot of sugary liquid may take longer.
- Sausages and similar. Blue Alpine’s “hard but possible” list includes pepperoni, sausage, salami, canned fruit, heavy cream, juices and canned vegetables.
Foods to Skip
Blue Alpine’s manual groups the foods that do not work into three kinds:
- Oil-based: chocolate, nuts, coffee beans, lard and butter, cooking oils, potato chips, peanut butter, mayonnaise and Oreos. Utah State University Extension likewise says high-fat foods such as mayonnaise do not freeze dry well.
- Not enough water: dehydrated fruit, candied fruit, salt, jerky, fruit leather, sugar and dry beans. (If you want to preserve those, a dehydrator is the right tool. See how to make beef jerky and making fruit leather in a dehydrator.)
- Too messy or too much sugar: honey, jams, Jell-O, soda, syrup, jellies and alcoholic drinks.
Harvest Right’s FAQ names peanut butter (very oil-based) and honey (too high in sugar) among its exceptions. The Blue Alpine manual also warns that pickles release acids that can damage the pump quickly, and that foods which may expand, such as candy and ice cream, can make a mess; for candy see our freeze-dried candy guide. Including oily or sugary ingredients in a freeze-dried meal will significantly reduce its shelf life, possibly down to a few months, according to the Blue Alpine manual.
Preparing and Loading Food
- Cut into small, uniform pieces. Utah State University Extension advises cutting food into small, uniform pieces. Blue Alpine says there is no minimum thickness, but food cut too thick may slow the process or not freeze dry at all.
- Spread food flat. Blue Alpine says all food should sit as flat as possible on the tray, with no stacking or overfilling. Harvest Right adds that food should not be higher than the sides of the tray.
- Freeze first if you pre-freeze. Harvest Right recommends freezing food for 48 hours before loading it if you load it frozen, and freezing sugary or salty foods longer and colder.
- Seal quickly. Freeze-dried food takes moisture back from the air. See how to store dried food for packaging basics.
Meat, Eggs and Safety
Blue Alpine’s manual says freeze drying does not cook food and that microbes and bacteria are not killed, they are preserved along with the food. Utah State University Extension says freeze-drying does not kill bacteria, that bacteria can become active again, and that food must be fully cooked either before freeze-drying or after rehydration. Start with fresh, properly handled food.
Quick Answers
Can you freeze dry anything?
Harvest Right says you can freeze dry almost anything, with exceptions such as very oily foods like peanut butter and very sugary foods like honey.
Can you freeze dry jerky?
Blue Alpine lists jerky under foods with not enough water, so it is not a good candidate. Use a dehydrator instead.
Can you freeze dry chocolate?
No. Both Blue Alpine’s manual and Harvest Right’s guidance list chocolate among foods that do not freeze dry well.
Can you freeze dry whole meals?
Yes, within limits. Oily or sugary ingredients can shorten the shelf life of the whole meal, per Blue Alpine’s manual.
Do I need a freeze dryer for this?
Not for every food. See freeze dryer vs dehydrator and our home freeze dryer guide.
