Main Ingredients
2.25lbsSweet Potatoes
1 tbspoil avocado or other neutral flavored oil
For a Sweet Seasoning add:
1/3cuplight brown sugar
1 tbspcinnamon
For a Savory Seasoning add:
1tbspsea salt
2tspsmoked paprika
2tspgarlic powder
2tsp onion powder
1/8tspcayenne pepper
Instructions
Preheat oven to 400ºF
Peel sweet potatoes and slice them to 1/8th of an inch or 3mm but any slices around that size will work.
Add all the sweet potato slices to a large bowl, after peeling this should be about 2lbs or 8 cups of sweet potatoes. Fill the bowl with cold water to soak for at least 30 minutes.
After soaking, pour the contents of the bowl into a colander to drain. Then rinse with cold water. Next, put an absorbent towel flat on a work surface or counter top and place the sweet potato slices on it to dry.
Meanwhile, mix together one of the seasoning options in a small bowl.
Pour the dry sweet potatoes back into a large bowl and add 1 Tablespoon of oil. Mix thoroughly so the oil is coating every sweet potato slice on both sides.
Pour in seasoning a mix until each piece is covered completely and as evenly as possible.
Prepare at least two half baking sheets by placing a sheet of parchment paper on each one. Arrange the sweet potato slices in an even layer.
Bake for 16-20 minutes, rotating trays half way through the cooking time. Sweet potatoes should be cooked thoroughly. They will not necessarily be crisp. Don’t let them overcook or blacken. Once cooking is complete, remove from the oven and let cool for a few minutes.
Prepare the freeze dryer. For the Harvest Right freeze dryer, press start. It will read “Cooling Vacuum Chamber. Wait 15 minutes before loading trays.”
Meanwhile, arrange sweet potatoes on freeze dryer trays in a flat layer.
When the cooling process is complete in the freeze dryer, load food into the freeze dryer, close the drain valve, and hit the continue button.
A cycle generally takes anywhere from 18-36 hours. The freeze dryer will automatically determine the length. After the process is complete, open the drain valve and remove the trays. Check to make sure the sweet potato slices are fully dry.
Immediately package the freeze dried sweet potato chips into vacuum sealed jars, mylar bags, or another airtight container so it doesn’t rehydrate and soften from the humidity in the air.
Store and enjoy!
