To dehydrate onions in a food dehydrator, start by slicing the onions thinly with a sharp knife or a mandoline slicer. Spread the sliced onions in a single layer on the trays of the food dehydrator, making sure they are not overlapping.
Set the temperature of the dehydrator to around 135°F (57°C) and leave the onions to dehydrate for about 6-10 hours, or until they are completely dried and crisp. Check on the onions occasionally to ensure that they are drying evenly and rotate the trays if needed.
Once the onions are dehydrated, allow them to cool completely before storing them in an airtight container. Dehydrated onions can be used in a variety of dishes such as soups, stews, salads, and as a seasoning in recipes. They will keep for several months if stored properly.

What is the best way to use dehydrated onions in soups and stews?
One of the best ways to use dehydrated onions in soups and stews is to rehydrate them first. To do this, place the dehydrated onions in a bowl and cover them with hot water. Let them sit for about 10-15 minutes until they are plump and rehydrated. Then, drain off any excess water before adding them to your soup or stew.
Alternatively, you can also add the dehydrated onions directly to the liquid in your soup or stew and allow them to rehydrate and soften as the dish cooks. Just be sure to adjust the amount of liquid in the recipe to account for the absorption of water by the dehydrated onions.
Using dehydrated onions in your soups and stews can save time and add a depth of flavor to your dish. Just be sure to rehydrate them properly to ensure they are soft and flavorful in the final dish.
How to cut onions for dehydrating?
- Start by cutting off the top of the onion and then slice it in half from top to bottom.
- Peel off the skin from each half of the onion.
- Lay each half flat side down on the cutting board and slice them into thin strips, about 1/8 inch thick.
- Next, turn the strips on their side and cut them into small dice, about 1/4 inch in size.
- Lay the diced onions in a single layer on dehydrator trays, making sure they are not touching each other.
- Set the dehydrator to the recommended temperature for dehydrating onions (usually around 135-140°F) and let them dry for about 8-10 hours, or until they are completely dry and crispy.
- Once the onions are fully dehydrated, store them in an airtight container in a cool, dark place. They can be rehydrated by soaking them in water before using in recipes.
What is the best way to transport dehydrated onions for camping or backpacking?
One of the best ways to transport dehydrated onions for camping or backpacking is to store them in a resealable plastic bag or airtight container. This will help prevent the onions from getting crushed or breaking apart during transit. Another option is to use a small, lightweight container with a secure lid to keep the onions safe and secure in your backpack. Additionally, you can pack the dehydrated onions in a small zip-top bag or portion them out into individual serving sizes for easier access while on the go.
How to tell when dehydrated onions are done?
Dehydrated onions are done when they are completely dry and brittle to the touch. They should not feel moist or soft at all. Additionally, the onions will have shrunk significantly in size and may have turned a slightly darker color. You can also taste a small piece to check for crunchiness and lack of moisture. Once they are fully dehydrated, allow them to cool completely before storing them in an airtight container.
