Dedicated food dehydrators may be worth investing in if you have the cabinet space and plan on regularly drying a lot of food, but all you really need is a little patience and a low-temperature oven to remove as much water content from fresh produce as possible. Oven drying fruit and veggies is an easy way to preserve peak-season produce at the height of its flavor without investing in any new gadgets.

Follow the guidelines below to start dehydrating food and use the recipes provided as inspiration for your own DIY snacks and pantry staples.

The Best Fruits and Vegetables for Dehydrating

Well-washed fruit such as halved strawberries, sliced apples, pears, bananas, apricots (and other stone fruits including peaches) are great for dehydrating. You can dehydrate mangoes, pineapple, tomatoes, and citrus too. Smaller berries can be left whole. Be sure to give the fruit a bath in a citric-acid solution (or lemon juice and water) to preserve flavor and color.

Vegetables can be great to save as well; some veggies like carrots and broccoli need a quick blanch in boiling water to clean off any bacteria and preserve colors.

In any case, make sure each piece is cut into the same shape to ensure even dehydration (aim for roughly 1/4 inch thick slices or strips).

How to Dehydrate Using Your Oven

1. Set a cooling rack on a baking sheet. The idea is that the cooling rack will promote dehydration and prevent liquid from pooling on a flat surface, but you can also simply line the baking sheet with parchment or a silicone mat.

2. Arrange your prepared fruits or vegetables on the rack in a single layer. They can be fairly close together, but should not be overlapping.

3. Set your oven to its lowest temperature (180°F or lower) and place the baking sheet on the middle rack.

4. Leave oven slightly open and ‘bake’ for a minimum of one hour, depending on the thickness of what you’re trying to dehydrate. Some fruits and vegetables will need more time, so check after every half hour or so.

Properly dehydrated fruits will be slightly pliable, but not sticky to the touch. Veggies will be crisp. Also worth noting: You can make your own beef jerky in the oven following much the same steps.

Other Methods

There are some things you can dehydrate in the microwave, like fresh herbs or potatoes (apple chips can be made in the same manner):

Sun drying is a fun option for some items like tomatoes, although the results are far less reliable (drying herbs this way is the least risky).

You can also dehydrate certain foods in your toaster oven.

How to Store Dehydrated Food

Once you’ve removed all of the moisture from your foods, it is best to store them in an airtight container or a plastic bag with most of the air removed before sealing. They should be kept in a cool, dark space to keep as fresh as possible.

Fruit Leather

Homemade fruit leathers are one of the best ways to sneak fresh produce into your child’s diet. It looks and tastes like the store bought snack, but has no extra sugar or preservatives to worry about. The process is a bit more involved—make a purée, spread it onto clean parchment paper, dry, and cut into strips with the paper for easy storage—but the principle is still the same. Get the Fruit Leather recipe.

Snap Pea Chips

Forget buying a bag of these crunchy peas every week, they are super easy to make at home. Sprinkle with your favorite spice blends for an extra kick or a sweet and salty spin if that’s what you’re into. Get the Snap Pea Chips recipe. (Crispy green beans are equally delicious.)

Tomato Chips

Take advantage of the season and consume all of the tomatoes you can get your hands on.
