Hey there, fellow kitchen adventurers! Today, let’s dive into the aromatic world of homemade onion powder – that humble yet mighty ingredient that can transform a dish from bland to grand in a sprinkle!

Let’s face it, onions are the unsung heroes of the kitchen. But when you’re in a rush or just want to add that extra oomph without the tears, onion powder comes to the rescue! Now, you might be wondering, “What’s the fuss? Aren’t all onions the same?” Well, my friends, buckle up as we embark on a flavorful journey through the onion universe.

First things first, choosing the right onion for your powder is crucial. Each variety brings its own unique flavor profile to the table.

• White onions: These onions have a sharp, strong flavor and are commonly used in Mexican and Southwestern cuisines. They have a lower water content compared to other onion varieties, making them ideal for dehydrating and grinding into powder.
• Yellow onions: Also known as Spanish onions, these are the most common type of onions and have a strong, slightly sweet flavor. They are a good choice for making onion powder due to their low moisture content and versatility.
• Shallots: Although not technically onions, shallots have a similar flavor profile and can be used to make a milder, slightly sweet onion powder. They have lower moisture content than most onions, which makes them suitable for dehydrating.
• Red onions: These onions have a sharp, slightly spicy flavor and are commonly used in salads and sandwiches. While they can be used to make onion powder, they have a higher moisture content compared to white and yellow onions, which may require a longer drying time.
• Vidalia onions: These sweet onions, grown in a specific region of Georgia, USA, have a mild, sweet flavor. Although they have a higher moisture content than other onions, they can still be used to make a unique, sweet onion powder. Due to their moisture content, they may require a longer drying time or a higher drying temperature to achieve the desired consistency or they will turn out clumpy. The resulting powder will also have a milder, sweeter flavor compared to powders made from more pungent onion varieties.

Now, onto the fun part – making your own onion powder! It’s surprisingly easy and oh-so-rewarding.

Baking or Dehydrating Homemade Onion Powder?

When it comes to making onion powder, you have the option of using a food dehydrator or drying the onions in the oven. While both methods can yield satisfactory results, we recommend using a food dehydrator because it won’t burn the onions, and you can just let it do its thing. But better yet, you preserve the nutritional value of the onions more effectively. The thing about dehydrating is that the onions can become quite potent as they dry, so you can always move a dehydrator to a room with an open window, you can’t do that with an oven.

That said, not everyone has a dehydrator, so let’s get into both methods!

5 Steps for Dehydrating Homemade Onion Powder

1. For a dehydrator, prepping your onions is the most important part. Use a mandolin to cut evenly thin slices (1/8” to 1/4″ thick) throughout your onions.
2. Spread on your dehydrator trays in one single layer each.
3. Cook on as low as 100-110°F, which will take a couple days to dry but will preserve the most nutrients. You could increase to 135°F and they will be ready in about a day. The warmer you go, the faster they will dehydrate.
4. Time will very every time you make them, it will depend on the moisture in the onion and how thick or thin the onions are. Cutting onions thicker will allow you to make more, but will double drying time. So in terms of time, the tell-tale sign they are done is when they crumble in your hands, and cannot bend at all, they are ready. There should be absolutely no moisture left.
5. Crush into a fine powder with a dry blender, food processor, or coffee grinder and store in an air-tight container with some rice to absorb moisture.

5 Steps for Dehydrating Homemade Onion Powder in the Oven

If you prefer to use the oven method, you could totally slice the onions like we did above and bake them, however you’ll get a lot more onion powder, less likeliness to burn, and a more even cooking consistency by grating them instead.

1. Preheat your oven to 170°F (75°C) and line two baking sheets with parchment paper to prevent sticking.
2. Cover a bowl with a couple layers of cheesecloth. Peel your onions and grate them into the bowl using a cheese grater or microplane. You could also use a food processor.
3. Wrap the onions in the cheesecloth, twisting at the top, and squeeze out as much liquid as you can. (The onion juice can be used in marinades and salad dressings!)
4. Spread out the onions on the baking sheets in an even uniform later and bake for about 5 hours, or more importantly, until they are completely dry and crumbling. The type of onion you use will determine how long they will need to cook. Checking every 30 minutes after 4 hours is a good tip.
5. Remove totally dried onions, allow to cool completely, then add to a blender, food process, or coffee grinder, and store in an air-tight container with some rice to absorb moisture.

Now let’s talk about recipes!
