Preserving Garlic

garlic cloves

Preserving garlic by any method is not a substitute for fresh, but it does have its own charms and advantages, especially if you grow it and have a bumper crop Here we’ll explore how to preserve garlic: freezing, drying, garlic vinegar, garlic salt, garlic oil, and refrigerator garlic pickles. Different methods of preserving garlic lend themselves to their own culinary uses, so explore them all and see which ones best suit your needs. There are six excellent methods for preserving garlic.

Before we examine the specific preservation methods, I want to emphasize that preserving garlic in oil is not safe unless the garlic oil is frozen. Garlic is a low-acid food and oil provides an oxygen-free environment, a combination that allows the growth of the bacteria Clostridium botulism, which causes botulism. However, if you follow the methods in this article for freezing garlic-and-oil mixtures and keep them frozen until needed, it is safe.

Here are a few useful gadgets for garlic lovers, that will help with peeling, mincing, storage, and the like:

Fresh garlic

Freezing Garlic

Perhaps the easiest way to preserve garlic is to freeze it. Just peel the cloves and place them in freezer bags in the freezer. Easier yet, simply place the unpeeled garlic in freezer bags and remove as needed. With both these methods, the cloves become a little mushy when they are thawed, but their flavor remains good.Another method for freezing garlic is to chop it and wrap it tightly in plastic wrap. With this method, you can simply grate or break off small amounts of chopped garlic as needed, which is helpful for cooks who often must quickly throw a meal together.

You can also freeze garlic that has been pureed in oil. This is nice because the oil keeps the mixture from freezing solid and it can be spooned out as needed, another help for busy cooks. To make frozen garlic oil puree, place one part peeled garlic cloves in a blender or food processor along with two parts olive oil. Puree the mixture, then immediately transfer it to a freezer container. Cover the container and place it in the freezer. Do not store the garlic oil puree at room temperature or in the refrigerator because the mixture can support the growth of Clostridium botulism bacteria.

Drying Garlic

Peel the garlic, making sure to discard any bruised or damaged cloves. Cut the cloves in half lengthwise, place them in an electric food dehydrator, and follow the manufacturer’s instructions for drying.

If you do not have a food dehydrator, you can dry the garlic in your oven. Make drying racks by stretching cheesecloth over the oven racks and securing it with toothpicks. Place the garlic on the racks and turn the oven to 140 degrees Fahrenheit for two hours, then lower it to 130 degrees until the garlic is completely dry and crisp.

Garlic Vinegar

To make garlic vinegar, take a bottle of white or red wine vinegar and drop in either whole or chopped garlic. Use as much garlic as you wish, as long as it is completely submerged in the vinegar. Store your garlic vinegar in the refrigerator and use both the vinegar and the garlic in salad dressings or any dish that calls for both vinegar and garlic. Garlic vinegar will keep, refrigerated, for about four months. If mold develops, discard the mixture.

Garlic Salt

Place dried garlic in a blender and process it until it turns to powder. Add four parts sea salt for each one part garlic powder and process for just a second or two to combine the two ingredients. Do not process the garlic salt too long because it will cake. Store the garlic salt in an airtight glass jar.

Garlic Oil

Fresh garlic and oil are a dangerous combination if left at room temperature. Because of garlic’s low acidity and oil’s lack of oxygen, they can cause botulism toxin to develop. However, peeled cloves of garlic can be added to oil and stored in the freezer for several months.

Commercially prepared garlic in oil contains a preservative to increase the acidity of the mixture and keep it safe. To make garlic-flavored oil at home, add dehydrated garlic to olive oil in a wide mouth jar, screw on the lid, and place the jar in the refrigerator. If the olive oil turns solid, just spoon it out. Be careful, however, to always use a dry spoon.

Refrigerator Garlic Pickles

Loosely fill a glass jar with peeled garlic cloves. Add enough red or white wine vinegar to cover the garlic and then add about one tablespoon of sea salt per cup of vinegar. Dried (not fresh) herbs such as red pepper flakes, bay leaves, and oregano may be added to taste. Cover the jar with a tight-fitting lid and shake to distribute the salt and herbs. Refrigerator garlic pickles will keep almost indefinitely in the refrigerator, as long as the garlic remains submerged in the vinegar.

We hope you’ve enjoyed learning the various methods of how to preserve garlic and welcome more of your comments, below.

    I just came across your site when I was looking up my garlic question. I puree garlic in bulk ( the Sams club size botte) with a little salt, put them in small freezer bags and freeze them to use. Recently I found that the ‘frozen’ garlic in the freezer remains in a semiliquid form ( soft sticky pulp, not frozen) even when the other items in the freezer are adequately frozen! Why does this happen? Should I be concerned about botulism?

    Hi Sam,
    I believe it is probably the salt that keeps the garlic from being frozen hard. Think of the salt sprinkled over icy roads in wintertime to melt the ice. Salt is a preservative, and the freezer is obviously cold enough to freeze other foods, so it feels safe to me, but I am a cook, not a scientist.

    I would think that garlic could be refrigerated (or home canned) in citric acid and water. I mixed 1 t. of citric acid in 8 oz. of water and using a pH strip, it registered a solid 1 which is extremely acidic. What does everyone think of this? Would it work?

    Emily,
    Re: Canning garlic and acidity.
    I suggest that you look up UC (University) of Davis “preserving garlic”- it explains that it it EXTREMELY difficult to home can garlic.

    I decided against the home canning method and am keeping it at 33 degrees with a pH of 1. I have the pH strips and am adding citric acid as needed to keep it at this extremely acid level. I just can’t stand the idea of wine flavored or vinegar flavored garlic…but a “lemony” favor is far less objectionable. If I’m still alive in 6 months we’ll know it’s effective!

    I have been chopping homegrown garlic and covering with EVOO then storing in fridge for use. We usually use it in a week or two and I repeat the process with fresh garlic from our stored heads, as the jar gets empty. We spoon it out of jar, oil and garlic together for use. Am I putting my family at risk doing this?

    Hi Judith,

    I think if it is in the refrigerator, and used quickly it may be ok, but frankly, I wouldn’t take the risk. Why not add some salt, and vinegar, or place it in the freezer? It will not freeze solid, and not be much different than in the fridge.

    hi
    i live in mijas publo southern spain
    most restaurants in this part of spain
    just put olive oil and garlic in bottles and leave it on the tables at room temperature (can be +35c) untill it is used
    i am sure this is not safe but after 12 years i have never heard of any problems!!

    Hullo all,

    Have just harvested & dried this year’s garlic crop (South Coast NSW) & am currently plaiting like a madman! However I will have lots left over that is not suitable suitable for plaiting & therefore will be looking to preserve some for that short period of each year between the old lot sprouting – Septemberish – & harvesting the next crop – mid to late Novemberish. Has anyone tried preserving peeled garlic cloves in brine? Did it work? What proprtion of salt?

    John.

    Well…it’s been 7 months and I’m still alive. The best method I’ve found is indeed using citric acid and maintaining the pH of 1 in plain water refrigerated. The garlic remains firm and the perfect color. Unfortunately I just ran out…so next May I will have to put up a half gallon instead of a quart. It held it’s flavor perfectly and was much better than any store bought. Runs a close second to fresh.

    Even better than pickling is to culture the garlic cloves (like traditional saurkraut, with whey from yogurt or other culture medium). It is a very old and more nutritious way of preservation. Needs refrigeration after fermentation.

    I placed a lot of peeled garlic in a glass jar with olive oil covering it in the refrigerator for about a couple weeks now. I just looked up how to preseve garlic. I’m afraid to use it now. Will it still be good if it has been in the refrigerator with only the oil?

      Martha, since it has only been a couple of weeks, and refrigerated, it should be OK, though this method is specified more for freezing. I can’t say, though, with 100% certainty, so if you feel uneasy about it, don’t use them.

    Hello,
    Thank you very much for this list of methods. I found it very helpfull. Just one point that might be improved… Botulism is caused by Clostridium botulinum (not by C. butulism).
    Thanks again

      Hello — why don’t you advise your friends to use this batch within a week, and if it is too much to use in such a short time, to freeze small portions. This should be fine.

      Hi Ralph — the garlic in jars in supermarkets has some sort of preservative to keep it fresh. One that is used is phosphoric acid, the same ingredient that’s used in cola drinks. While it’s probably safe in minute amounts, phosphoric acid is not considered a healthy ingredient and too much can lead to side effects. Before you consider buying, see what is used as a preservative and do a quick search on it!

    I’m addicted to garlic stuffed olives.I realized I like the garlic better than the olives. Would it work to buy cheap bottled olives and put the garlic in the olive brine? Would it work for pickles too? Should I heat the brine? Blanch the garlic? Any ideas.

    Also, the place I buy the stuffed olives has gotten rid of the brine & covered in olive oil. After reading about not storing garlic & olive oil is this olive garlic & olive oil combo safe?

    Hello, what about lacto fermentation. Myself and others in our off grid community have been lacto fermenting a lot of our veggies as we believe it is excellent for our stomachs. We put 2 tablespoons sea salt to one quart of water . This works well. You can do a search to find wonderful recipes.

      Wyatt, this is a really good question, but I couldn’t find a straight answer (and I couldn’t reach the author of this article). Like all fresh foods, probably the sooner used, the better. My semi-educated guess is 1 to 3 months. If you find anything more specific, can you come back and post it here? Thanks!

    I have harvested a lot of garlic this summer and have read all the above comments on preserving, I am going to try the puree and oil method and freeze in ice cube trays so I can pop a small or large amount straight into my cooking, I have in the past simply put the garlic into olive oil with peppers and herbs, but will stop this method now.

    After peeling my freshly harvested garlic and then minceing, it was placed in a steralized jar and put in the fridge, no salt, no oil….. I used this very large jar of garlic, over a period of 18 months, whenever fresh cloves were not available, this was always used cooked in dishes. All members of the family and visitors alike are still alive and very healthy….

    I am almost 40. My whole life I saw my mom and aunts buying garlic by bulk and making into puree with canola oil. Then put it into a glass container and stored in the refrigerator. I am doing the same but using EVOO instead the canola. We all are very alive and healthy. I am not saying it is the right thing to do, I j ust wanted you guys to know it.

    After experimenting with most of the mentioned methods of preserving garlic I have ended up just roasting fresh peeled cloves with evoo and salt & pepper and refrigerating. When I need garlic just a quick chop and and then used in any application. I find that the previously roasted has a sweeter taste and lacks the bitter bite that I get ( usually just the smell) sometimes when sauteing fresh uncooked garlic. So I buy bulk peeled garlic (US grown only) and roast and refrigerate for future use Garlic is GREAT!

    Lacto fermentation is the best way to store foods and was used for millenia around the world till big business came along and wanted us under their control so they can bleed our bank accounts if we just rely on them and their unhealthy products that is dead food, lacto fermented food is living and our bodies just love it.
    My grand mother did this to all her vegetables and lived over 100 years in health.
