Unlock More Flavor: Make Your Own Onion Powder

Onion powder is a versatile ingredient that adds depth and complexity to countless dishes. While it’s readily available in stores, making your own at home with a dehydrator not only ensures its freshness but also allows you to customize its flavor and potency. In this guide, we’ll walk through the simple steps to create aromatic and flavorful onion powder using a dehydrator.

Why Make Onion Powder at Home?

Commercially produced onion powder often lacks the vibrant flavor of freshly made alternatives. By making your own, you can ensure that you’re getting the full intensity of flavor from your onions. Additionally, homemade onion powder contains no additives or preservatives, making it a healthier option for you and your family.

Choosing the Right Onions:

The first step in making onion powder is selecting the right onions. While any type of onion can be used, yellow onions are commonly chosen for their balanced flavor. However, if you prefer a sweeter or more pungent taste, you can opt for red or white onions respectively.

Preparing the Onions:

Start by peeling the onions and slicing them into thin, uniform slices. This ensures even drying and prevents any pieces from drying out too quickly or remaining undercooked.

Dehydrating the Onions:

Once sliced, arrange the onions in a single layer on the trays of your dehydrator. Set the dehydrator to a low temperature, typically around 125°F to 135°F (52°C to 57°C), and allow the onions to dry for 8 to 12 hours. The exact drying time will depend on factors such as humidity levels and the moisture content of the onions.

Checking for Dryness:

To test if the onions are fully dehydrated, they should be brittle and break easily when crushed between your fingers. If they still feel soft or pliable, continue drying them until they reach the desired consistency.

Grinding into Powder:

Once the onions are completely dried, transfer them to a spice grinder or food processor. Grind the dried onions into a fine powder, taking care not to overfill the grinder to ensure even grinding.

Storing Your Onion Powder:

Store your homemade onion powder in an airtight container, preferably a glass jar, in a cool, dark place. Properly stored, homemade onion powder can last for up to a year, retaining its flavor and potency.

Using Your Homemade Onion Powder:

Now that you have your freshly made onion powder, the culinary possibilities are endless. Use it to season soups, stews, marinades, rubs, sauces, and dressings, or sprinkle it over roasted vegetables, meats, and popcorn for an added kick of flavor.


Making onion powder at home with a dehydrator is a simple and rewarding process that allows you to elevate your dishes with the vibrant flavor of fresh onions. By following these easy steps, you can enjoy the benefits of homemade onion powder in your cooking while adding your own personal touch to every dish. So, why settle for store-bought when you can create something truly special in your own kitchen?
