Set dehydrator to 100°F / 40°C. Dehydrate for 18-24 hours. Flip them every 8-10 hours so that they dry evenly.

Test them after 24 hours. If they are not quite dry, continue to dehydrate until they are dry. They can take up to 48 hours.

If you would like to speed up this process, you can turn the dehydrator up to 170°F / 80°C. They will take 4-6 hours at this higher temperature. The reason we like to do them at a lower temperature is that they keep their lovely color much better. Turning up the heat can make the natural sugars in the grapefruit turn brown.

See section below entitled “How to tell if grapefruit are dry”

How to dry in the oven

Grapefruit can be baked in the oven to dry. Perform steps one and two above. Place them in a single layer on parchment paper lined baking trays. Turn oven to it’s lowest setting (generally 150-170°F / 80°C) Slide the sheets on to the oven rack, crack open the door and prop it with a wooden spoon or something similar that will not conduct heat.

Allow them to dry for about 4-6 hours. Flip them over every 30 minutes or so. This will ensure that they dry evenly.

How to air dry/ sun dry

If you live in a hot, dry climate, think Arizona or southern California, you can air dry / sun dry grapefruit too. Perform steps one and two above. Place them on a piece of cardboard or on parchment lined baking sheets. Allow them to dry for a least a couple days.

If nights tend to be damp, remove them to the house or garage and then place them back out in the full sun the next day.

How to tell if grapefruit are dry

Since these fruit have so much sugar, they may still look a bit shiny due to the sugars on the outside of the slices. To test, break a slice in half. The rind should crack pretty easily and have very little bend left. (the flesh will still bend)

How to condition dried fruit

Dried fruit must be conditioned to prevent molding. This is an important step.

  • Fully cool the fruit on racks.
  • Add to containers with a very tight fitting lid. Canning jars are perfect for this.
  • Shake the jar daily for 7-10 days. This will help them not stick together.
  • Check the jar daily. If you see any tiny droplets of moisture or condensation inside the jar at any point. You will need to more fully dehydrate them. Return them to your dehydrator for additional drying time.
  • If you see any evidence of mold, discard the product.

Notes

How to tell if slices are dry enough
Since these fruit have so much sugar, they may still look a bit shiny due to the sugars on the outside of the slices. To test, break a slice in half. The rind should crack pretty easily and have very little bend left.
Note: Drying times are estimates. The actual time will vary depending on the thickness of slices and the size of the fruit.
Conditioning your dried fruits
What is conditioning dried fruits?
Conditioning is the process of testing the fruit to make sure that it is thoroughly dry.
Why is conditioning important?
Even a bit of moisture in a couple of pieces has the potential to ruin a whole batch.
How do you condition fruits?
Allow the dehydrated fruits to come to room temperature. Immediately place them into a glass mason jar. Place the jar in a dark area.
Shake the jar daily to break up any stuck pieces. Allow them to stay in the jar for 7-10 days, shaking daily.
If you see any moisture droplets collecting on the jar. You know you have moisture in them.
What if I see moisture after conditioning?
If you see any evidence of moisture in the jar, re-dry the food in your oven or dehydrator. After re-drying condition them again. Once they are fully dry, pack in tight fitting glass jars.
How to use dried grapefruit slices
  • Use the slices for a garnish for cocktails. They are especially good with gin cocktails.
  • You can use them to garnish cakes, and breads.
  • Use to flavor water, sparkling water or punches.

  • Make a garland with other citrus.
  • Give jars to friends and family for a fun homemade gift around the holidays.
How to store them
Once they are dried, and have been conditioned, store them in a glass jar or similar airtight container to prevent them from absorbing moisture from the air. They can also be vacuum packed for long term storage.
If using a jar to store it is a good idea to add a food safe silicone pack to absorb moisture.
Dried grapefruit slices will last at least a year, if they are well packaged to prevent moisture from entering their storage container. Store them in a dark, dry, cool space to prolong shelf life.
