If you’ve ever bought spices from the store, you probably noticed that they often contain ingredients like “anti-caking agent” or “natural flavor” (aka MSG). Many often contain trace amounts of soy or other fillers, and sometimes these don’t even have to be listed on the ingredients.

Mystery fillers aside, these spices also often sit on the shelf, in plastic bottles, for a long time. By the time you bring them home, they have lost much of their flavor (and did I mention they might contain soy, MSG, or other additives!)

As with many aspects of natural living, simple is often cheaper, easier, and more healthy. Making your own garlic, onion, and chili powders (or a blend of all three) can be one of the easiest and tastiest changes you can make. These are also a great addition to homemade spice blends!

The gist of making these homemade seasonings is to simply dehydrate pieces of garlic, onion, or pepper in a dehydrator or on the lowest setting of the oven until the pieces are dry and brittle. Then, just powder them in a coffee grinder or blender and store.

Fun fact: Did you know that paprika is actually a type of chili powder that uses only sweet red peppers?

  • fresh onions garlic cloves, or chili peppers of choice


  • Gather a few onions, several heads of garlic, or 8-10 peppers. 
  • Make sure all vegetables are clean, and peel onions and garlic cloves.
  • Slice onions and garlic into thin slices and put on a sheet in the dehydrator or on lowest setting in the oven. Slice peppers in half and remove seeds and place on dehydrator sheet or on baking sheet in oven on lowest setting.
  • Dehydrate until they are completely dry and not leathery. They should be brittle enough to break by hand. Check every few hours and remove any pieces that are done.
  • When all are done drying, put into coffee grinder, food processor, or blender. If you want individual spices, blend separately.
  • Once they are finely powdered, leave them in the food processor or blender with the lid on for at least 10 minutes to let it settle. This is important! Trust me… I learned the hard way! Opening it too soon will lead to a rapid sinus cleanse 🙂
  • Store in glass jars and enjoy!

    Really enjoy your site! Have printed many recipes for every day usage and have started a notebook. Question – What dehydrator do you highly recommend. Would love to buy one soon! I’ve made our own deodorant & toothpaste and look forward to moving on to other adventures! Thank you

    Hi! I was wondering if you have an idea of how long will it takes to dry the onion/garlic in a traditional oven? I don’t have a dehydrator… Yet 🙂

  3. Colleen Avatar

    This looks great! How much powder can be made from these amounts? Say, from one onion?

  4. Barbara Avatar

    Do you put the onion on any special kind of rack in the dehydrator? I just got one today and I’m excited to try this out.

  5. Jessica Avatar

    I am new to your site, and must say I LOVE IT! This may be a silly question however, do you have a cook book of all your receipes?

    We dry our peppers and use them in chunks, flakes, or powder. Plan to start making own onion & garlic powder – recently found out I am allergic to corn. Corn powders/cornstarch is a common filler in many products. Thank you for sharing this!

    I have made garlic and green onion powder. I find that I get better consistency by puree them before I dehydrate. Makes it easier to grind after.

    1. Amy Avatar

      How does the puree process work? Does it burn if you don’t turn it? I’ve never really worked with anything on the lowest setting in the oven so I’m not sure, but the puree idea sounds great.

    Has anyone tried this with a waring pro dehydrator? I was set on making onion powder with it for my first time using it, but I have no clue what setting to pick…

    Two questions, what is the estimated shelf life? Do you know a source where I can find glass (preferred) or bpa free shaker bottles for storage of the powders?

      If completely dry, they will last indefinitely, but they will lose some flavor after the first 6 months…

      Erica, I just recently found some Ball brand herb storage jars. I was looking around the canning section at Walmart and there they were. They come in packs of 4 and come with BPA free shaker tops and lables (the lables don’t stick very well though). They have a very wide mouth, so they are easy to fill. Also, you can buy canning tops separately to fit the smaller jars. They are a little wide, but they fit on my spice rack. I have already filled up my first set with dried herbs and am going to get more tomorrow. I plan to put my homemade toothpaste and deodorant in them. Going to try making my own jams also!

      Penzeys spices also sells empty glass spice bottles in various sizes.

    I’ve grown my own herbs and let them dry out.  They last longer and taste better.  Just cut a few sprigs of your favorite herbs and place on a paper towel covered counter.  Turn over as needed. In a few days you will be able to rub between your fingers into a dry herb.  Place in airtight container and store until ready to use.  I’ve had success with thyme, basil and dill…I never seem to have what I need at the right time, so by adding to my cupboard dries, I’m assured I’ll have it when I need it.  Do it all summer long and have fresh herbs long into the winter.

    I have never done spices on my own, but one time I was in a real pinch and put regular granulated white sugar in my coffee grinder and made powdered sugar. It was quick and easy and I have to admit I was surprised that it worked! But now I can buy my white sugar in bulk and then I can make my own powdered sugar and save some money

    I already grow and dry a lot of my spices like rosemary, basil, lavender, etc. but I never thought to make onion or garlic powder. If it’s dehydrated it should last quite a while, right? What a great idea. And my own chili powder… hmmmm 🙂

    can you specify want kind of peppers? Are the jalapeno, poblano etc? I would really like to make my own chili powder. That is similar to the store but without the fillers.

      it depends on how spicy you want it. anaheim and chili peppers make a
      less spicy powder, where habenero or jalepeno make more spicy ones.
      you can even use sweet peppers and get the taste without the heat.

    Another thing about store bought spices is that they are often irridated and they don’t have to tell you that so I always ask but good luck trying to get a right answer. Trader Joe’s told me they don’t irridate theirs but the best way for sure is to buy organic ones or make your own. Great ideas thanks so much for them. Blessings!!!

        The word is irradiate, not irridate. It is perfectly safe. There is nothing radioactive in it. You get far, far more radiation from the sun or an x-ray. Some CT scans can give you a dose of radiation as large as spending a year in the sun. I repeat – irradiated food has NOTHING radioactive left in it.

        1. Janne Avatar

          Irradiation damages the quality of food.
          · Irradiation damages food by breaking up molecules and creating free radicals. The free radicals kill some bacteria, but they also bounce around in the food, damage vitamins and enzymes, and combine with existing chemicals (like pesticides) in the food to form new chemicals, called unique radiolytic products (URPs).
          · Some of these URPs are known toxins (benzene, formaldehyde, lipid peroxides) and some are unique to irradiated foods. Scientists have not studied the long-term effect of these new chemicals in our diet. Therefore, we cannot assume they are safe.
