Dried Grapefruit
These Dried Grapefruit only take a few minutes hands-on time. They are great for garnish, baking, decoration and more.

What you need
You only need whole, fresh grapefruit. Some grapefruit have thinner skins than others, hence less pith, which is bitter. Try to find thin skinned varieties.
Try to source organic grapefruit that have not been sprayed with chemicals. If you can’t find organic then wash the skin with soapy water and rinse with hot water. Dry off before slicing.
How to grapefruit in a dehydrator
Step One
Wash and dry fruit well.

Step Two
Using a sharp chef’s knife, serrated knife or a mandolin, slice ¼ inch (6 mm) thick slices.

Step Three
Arrange them on racks.

Step Four
Slide racks into dehydrator.

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.
See section below entitled “How to tell if grapefruit are dry”
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 use your air fryer
Preheat the air fryer to it’s lowest temperature. Perform steps one and two above. Arrange slices on air fryer basket. Air fry for 30 minutes. Remove and flip the pieces over. Air fry for an additional 20 minutes.
Check the progress. If the grapefruit are not quite dry, air fry in 5 minute intervals, turning the them over each time you check, until they are dried.

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.

How to store them
Store dried grapefruit in a Mason jar or similar air-tight container. We’ve found that adding a food safe silicone packet will prolong the shelf life of the product by reducing potential moisture contamination.
Dehydrated grapefruit will last at least one year. Store them in a cool, dark, dry place to prolong shelf life.
How to use them

- Grind them up in a coffee mill or spice grinder and make a grapefruit powder.
