To dry apples in the microwave, peel and core them, slice them thinly, soak them in lemon water, arrange them on waxed paper and microwave them on the defrost setting. Dehydrating apples in the microwave requires apples, a knife, lemon, waxed paper and a microwave. It takes roughly 15 minutes plus drying time.
- Peel and core the apples
Use a sharp knife to remove the peel from the apple. If you have an apple corer, use this to remove the core. If not, just use the knife to cut away the core without slicing the apple.
- Slice the apples
Cut the apples cross-wise so they make rings. Each slice should be roughly a quarter-inch thick. Each apple typically yields 10 rings.
- Soak the apples
Mix half a gallon of water with 1 tablespoon of lemon juice in a large bowl. Place the apple rings inside the lemon water. Soak the rings for 2 minutes. Remove the apples, drying them with a tea towel.
- Arrange the apples
If your microwave has a removable revolving plate, take this out and put a sheet of waxed paper on top. Otherwise, place the waxed paper on a large plate. Arrange the apple rings on the waxed paper in a single layer, ensuring they are not touching each other.
- Microwave the apples
Place the apples in the microwave. Use the defrost setting to microwave the apple rings for 35 to 45 minutes or until the rings feel slightly rubbery.
