Prepare your favorite recipe for homemade baby food.
Spoon prepared food into ice cube trays or silicone molds.
Cover trays with cling wrap and place trays in a freezer for at least 2 hours or, for best results, up to 24 hours.
Bring your freeze dryer to the recommended temperature before removing the baby food from the freezer.
If desired, prepare freeze dryer trays with parchment paper or silicone mats.
Remove trays of baby food from the freezer, discard plastic wrap, and transfer the cubes to the freeze dryer trays.
Load the trays in the freeze dryer, put the insulating cover in place (for older models), and shut the door.
Set the timer for 20 hours, checking when the signal goes off, and if it’s not completely freeze dried, return it to the freeze dryer for 2-hour increments until done.
Store baby food out of direct sunlight in well-labeled containers with oxygen absorbers.
