Instructables
Well maybe you are in a pickle like I was the other day.  I had just seen ectadie's instuctable for how to make cute owl cheese crackers.  Inspired I start gathering my ingredients and surprise surprise I had no onion powder.  Faced with this I Had three options as I saw them. First I could go to the store and buy some. *Shudder* That would involve getting out of my PJ's so it was off the table.  Second I could shake my fist at the sky and hope the crackers would still be tasty without onion powder.  I was getting ready to go this route when it hit me.  I was browsing instructables there had to be a way.  So I did a quick search and came up empty handed.  I thought the lack of a diy onion powder instructable was unacceptable.  I decided to rectify this and garbed my camera to document option three.  Make your own!  Now lets get started.

Step 1: What you will need

DSC_4612.JPG
Tools
  • Oven or Food Dehydrator
  • Knife
  • Cutting Board
  • Mandoline Slicer or Impressive knife skills
  • Kevlar Glove (not necessary if you have the aforementioned impressive knife skills.)
  • Baking Sheet
  • Cooling Rack or Aluminum Foil(it just takes a lot longer)
  • Spice Grinder or Blender or Food Processor or Mortal and Pestle
  • Jar(for storage)
Food Stuffs
  • Onion (One of the good things about making your own powder is you can choose the variety of onion you want for a unique flavor)

Step 2: Preheat your oven grab your tools

Turn your oven on to 150°F (66°C) and if you are like me by the time you remember where you hid your mandoline slicer the oven should be good to go.

Step 3: The Cuttening

Now that you have all your tools let's get slicing. First cut the bottom and the top off your onion to make it easy to peel.  Peel the outer layer off then don your glove and get your partner in crime to take a picture.  Now that is out of the way it is time to use either your knife skills or your mandoline slicer to cut the onion into little .

thanks for the fun instructable,dont worry about the stove,tells us youre a cook!! i have just put mushrooms in the oven to try this out,wonder how to do tomatoes,i pay a lot online for powdered tomato ,surley theres a wy to do it at home..does anyone know??

I am glad you liked the instructable. Let me know how the mushrooms work out. My guess is you could do the same with tomatoes they would just take a really really long time to dry enough to powder.

Dude, first and foremost, clean your damn stove, pretty gross! Second, I made the onion powder, which turned out great, BUT only after I had the onions sit in the oven for 6, yes 6 long hours at 170 degrees because my oven does not go down to 150. I will make this again, but experiment with using a higher temperature - maybe 200 degrees and hope for 3-4 hours.

How long will this DIY Onion Powder last? IE shelf life. how long can I store it? methods to preserve it for longer periods of time?
the drier it is, the longer it lasts, to a point. Make a few vacuum bottles and use a cheapo hand pump. Keeps out moisture as well as bugs. An open bottle of powder in my kiten lsts 3 months.

If you vacuum a bottle then freeze it it lasts a good 6-12 months. Keeps a big bottle for bulk and then a small one for the cupboard. Re vacuum the storage bottle when opened. GREAT FOR AMMO STORAGE AND CHILI POWDER, many would argue they are the same thing!

You can make vacuum seals for about 1/1000,000,000th of a penny depending on whatcha got laying around. The vacuum pump will set you back about 10 schadoles.

If you have a vacu sealer they usually have a hose attachment and there are lid sealers that use mason jar lids.

They are NOT TO REPLACE BOILING WATER BATHS, only for seeds/herbs/dry goods/jerky/cremated inlaws!

Adding a small amount of salt will really increase the shelf life too.

I had no idea how easy it could be. Thanks for posting.
I am glad you liked it. Thanks for looking.

Great idea ! One problem I have with spices is that they add salt to many of them. You could make many things like blackened seasoning without the salt. Awesome! I just never thought of that. Also when your celery starts getting a little limp... dehydrate it you don't even need to powder it. Your idea worked great on carrots also. I tried drying mushrooms that either needed to be used or tossed. I did use a dehydrator on as low of a temp as it would go. I now have 2 quarts Thank you never thought of doing this
I learned a trick (by accident) that has saved me from having my mushrooms melt into a slimmy mess. Take them out of the plastic covered box and store them in a closed paper lunch bag. If you should forget them before you get them used up , the fridge does a fine job of drying making them perfect for grinding into powder - no dehydrator necessary.
I rinse my mushrooms in a bowl with a little lemon juice, the Ascorbic acid keeps them from discoloring. Rinse in bowl dry with a paper towel and now into a paper bag. Thank you !!!

I like, Gives me an idea. I will do this with my home built smoker. That's how I dry my jerky. Yap, smoke flavored onion powder. I can almost smell it now. Thanks Tinker.
That sounds like a great idea. Let me know how it turns out.
Do peppers as well then you have homemade smoked chili powder!

An electric coffee grinder works REAL fast and makes a super fine powder. I did this to make myself some ginger powder and it worked fantastic.
Do you bake the ginger as well?
Have you tried any other dried vegetables or condiments that might be powdered?
No, I just had some ginger uncovered in the 'frig and it dried out, so I 'gingerly' cut it up into slices and then smaller pieces and put all into a coffee grinder and gave it a good grind until most was powdered. I strained it, put it in a glass jar and it was VERY potent and fragrant. I've meant to try it with other spices, but so far, the only one I've tried has been the ginger and some dried rosemary.
that's right, I also once had a bit of ginger drying in the fridge (my fridge has an air circulating between the freezer and the fridge part, very efficient for drying). I'll try that another time, thanks!
I threw out countless old dried out mushrooms and shrivelled parsley that was left in fridge while we prepped big holiday meals. One day I bought dried mushrooms for a special sauce ggggrrrr I realise how dumb I was. when I buy shrooms or too much parsley, I slice or chop lay on plate put on any free surface 3 -4 days later wallla dried mushrooms, and not 45 bucks a pound.

If you dry thyme don't even destem it just clean stems of crud rinse lightly shake off and dry room temp is good a warmed tirned off oven is better. A real dehydrater of ANY kind is best (fastest). You can now rub the leaves off or make a bale put in a sealable bowl/can. If it is vac-able even better. Destem as you need it .

I grow it all year (right now under some snow if I need it), use it on many things.

Hold bundle in hand and roll it they all come off in a shower of great tastyness

Sun dry your mushrooms for extra vitamin D! Here's the reference 
Great tip, thanks (I didn't know that) :-)
Isn't it an odd fact? This is the only food that I know of which has more vitamins preserved rather than fresh.
because you gave it a "treatment" a natural one , but a process!!

thanks
THANKS I can make shrooms for eating and stop taking supps! Well it would become the supplement. Add to it some Ceylon Cinnamon, and you're n your way.

Hello.yYou've a good way of fixing them.
Try this - Carmelize your onion (jalopeno),treat them like fruit roll-ups in your dehydrator.

:)

Forgot > Run them through your blender,before you put it all in the dehydrator.
If you like to dehydrate don't stop with just onions. I do Kale Chips, Tomatoes, bell peppers, celery, oregano, basil, chives, mushrooms, rosemary, catnip (for the cat) :) bananas, apples, cherries, pineapples, orange peel, fresh coconut, grapes into raisins, and all types of jerky - beef, chicken, fish, pork & hamburger. Sparkie said it right - seal it tight and it will last. Anything can be powdered after drying. Fruits for muffins, cakes and vegtables for soups and main dishes. Even meat can be ground for baking or cooking purposes.
Red Onions are a taste treat. They sweeten when dried. I buy a large amount a couple times a year to dehydrate. Some are then ground or minced for soups and stews. Remember to add some of your favorite herbs for a flavor to savor. Oregano or basil is a good choice.

Great! My hubby goes thru dried onion powder like it's going out of style. I'm wondering how economical your process is compared to the 2.62 ounce 5th Season jar from walmart that's only 50 cents. But if your's tastes better, this might be worth it costing more to make. I'm going to try it out & see if it tastes better & what the cost comparison is. Thanks for the fun lesson :)
I don't know how economical it is but it sure is tasty.. I am hoping this summer to build a solar food dehydrator which would probably help in the economic factor as I would not have to pay for the natural gas. I think part of what makes this cool other than the pointing and saying "I made that" is that if you pick onions with a different flavor profile like sweet or red you can get an onion powder that you could not get in the stores.
Yes! A solar dehydrator is an excellent solution to the cost of energy to make this. I figured up the cost comparison between the ready-made powder I mentioned and the results from a sale-price 69cent 3 pound bag of yellow onion from Aldi and got 19 cents an oz for store-bought and about 14 cents an oz for home made so there is some savings, especially if you use solar and don't pay for electric or gas oven use. But overall, you can't put a price on having the flavor variety you mentioned and the "I made that" factor. Those are pretty priceless factors, which tip the scale even more towards home-made for my onion-powder-loving hubby. And, to Maxhuey's question, yes, my hubby eats raw onions by the ton too! I'm actually shocked he hasn't turned into an onion after 25 years of watching him consume pounds of onions per week! ;) I like the idea of making various powders for him for his b-day - he will love it! Thanks Tinker-P for the idea!
If you make a solar dehydrator add a light bulb(s) ,incandescent type inside the unit. Depending on were you are humidity can easily settle on you product by morning, leading to off tastes/molds etc. 1 or 2 two light bulbs built into to the unit will drive off moisture and keep the process going overnight. The lamps can be like 25 watts or 1 50-75 watts. If the day start or ends badly your light bulbs will work nicely,

Remember the Easy Bake Oven, they work with a light bulb and bake little cakes.

Some restaurants get oil in 5 gallon "cans" which are square You could use two or 3 of them to make a body. I used two to make a jet stove .

In all fairness though a 20 dollar cheapie for simple stuff, while no fun , is a good investment. But a good one, if you do a lot, is a better long term deal.

A solar one is a good deal, and the lights give it "back up" for overcast days and overnight moisture protection.

great instructable
