This easy recipe for Honey and Onion Cough Syrup is a old folk remedy for cough and colds. It combines the well known benefits of onion and honey to create a simple, affordable homemade cough syrup to help sooth a sore throat and clear excess mucus.

This simple, timeless recipe for Honey and Onion Cough Syrup was first introduced to me in the book Medicinal Herbs by Rosemary Gladstar. It’s a folk medicine recipe that has been passed down throughout the generations, and a quick look online shows you that something similar has been made for countless generations in cultures all over the globe.

While many traditional recipes call for steeping the raw onions in with the honey for several days, Rosemary’s is different in that she warms the honey ever so slightly, allowing the onions to soften and release their beneficial sulfur compounds.

I add a little garlic to my version (although it’s optional), as well as give you more structured ingredient amounts and recipe times so it’s easy to create in your own kitchen.

Reasons to Love This Recipe:

  1. It’s made with simple, household ingredients that have great healing properties.
  2. Easy enough for a beginner to make.
  3. Tastes surprisingly good, making it a bit easier to give to sick kids.
  4. A powerful folk remedy that has been used for generations and generations.

Honey and Onion Cough Syrup Benefits

Both honey and onions have been used for millennia to cure common ailments such as cough, cold, and respiratory issues. The use of these two household ingredients in folk remedies is almost as old as time itself, and the combination is still used to this day.

Since honey and onion cough syrup contains both honey and onion, it combines the benefits of each of these into one (surprisingly) delicious syrup that is easy to make.

Here are just a few benefits:

  • Honey is antibacterial, anti-inflammatory, and a powerful antioxidant.
  • Honey soothes a sore and tired throat.
  • Onion contains the antioxidant quercetin, which fights inflammation in the body,.
  • Onion is high in sulfur compounds (as is garlic), which has been shown to help with a variety of health issues.
  • Since onion is an expectorant it helps clear mucus, which is common with a cough.
  • Onions have electrolytes, which is essential for keeping hydrated during an illness.

Ingredients

The ingredients needed to make a homemade cough syrup: honey, onions, and garlic (optional).
  • Onions: You will need 2-3 onions. If you don’t grow your own, I recommend seeking out an organic option. Since it’s a medicinal recipe it’s a good idea to invest in the best quality.
  • Honey: Seek out raw/unpasteurized honey. You’ll get all of the beneficial enzymes, as well as the antibacterial, antioxidant, and anti-inflammatory effects of honey.
  • Garlic (optional): This is an optional ingredient, but garlic is well established in herbal medicine. Use organic or local garlic if available.

IMPORTANT NOTE: Honey is not safe for babies under the age of 1 year to consume. You could try a preparation made with maple syrup or glycerine instead, but be sure to consult with your health care provider first.

How to Make Cough Syrup with Onion and Honey

To get started, simply peel and cut your onions in half. Then slice them into thin half-moon shapes. Add them to a medium sized pot, then add in some chopped garlic (2-3 cloves) if desired.

Adding honey to a pot with sliced onions.

Add in the honey, drizzling in enough to completely cover the onions. They do not need to be submerged under an inch or more of honey, just enough that all of the onions are coated and covered.

Place your pot on the stove, and heat over low heat until the onions are very soft and slightly mushy. Stir occasionally to encourage even heating – the mixture should never feel hot to the touch, just warm.

Simmering onions in honey until soft.

It will take around 1-2 hours for your onions to soften, and you may need to increase the heat ever so slightly if the onions are not losing their shape within the first 30 minutes or so.

Once the onions are soft and slightly mushy, taste your syrup to check the flavor. It should taste pleasantly of honey with just a touch of onion – it’s surprisingly tasty!

Allow it to cool to room temperature completely before transferring to a jar for storage – this prevents condensation and moisture in the jar.

Dosing Recommendations

At the onset of symptoms: Take 1/2-1 teaspoon (2.5 – 5 milliliters) every 1-2 hours.

Treating an active cough: 1 teaspoon (5 milliliters) 3-4 times per day until you have recovered.

Storing and Shelf Life

Once your honey onion cough syrup has cooled to room temperature, transfer it to a clean jar with a lid. This can be a swing-top jar or a wide mouth mason jar with a plastic lid. Just make sure it’s nice and clean to ensure the longest storage possible of your homemade cough syrup.

If you leave the onions in the syrup you can expect for this to store in the fridge for up to 1 week.

If you want it to store for 2-6 months, just carefully remove the onions using a clean utensil. Then transfer to the fridge and watch carefully for signs of spoilage such as an off smell, color, or mold growth. Discard if there are any signs of spoilage.

Variations and Substitutions

With lemon: When making honey syrups I like to avoid adding liquid when possible, as this can shorten the shelf life. If you want to add lemon to your honey onion syrup, I’d recommend setting aside 2-3 days worth and adding fresh lemon juice to taste to the small amount. This will help prolong the storage of your main batch.

With ginger: Add 2-3 teaspoons of freshly grated ginger in with the garlic and onions. Ginger has been shown to reduce nausea, and is also anti-inflammatory.

Without honey: If you have babies under 1 year at home (but older than 6 months), you may be wondering if there is a way you can make honey and onion cough syrup without honey. I haven’t tried it myself, but popular substitutes for honey in herbal remedies include maple syrup, glycerin, and brown sugar. Be sure to check with your healthcare provider before giving it to children.

Note that if you use maple syrup or glycerine, your storage time is reduced as well. I would recommend 2-3 days with the onions in the syrup, and up to 2 weeks without the onions as a starting place. Discard if there are any signs of spoilage such as an off color, presence of mold or growth, or an off smell.

Frequently Asked Questions

Is honey and onion good for a cough?

Honey and onion have been used together for centuries to help with cough and cold. Onions have been used in folk medicine for many years to help with respiratory issues, and is still used today to treat mild coughs. Honey contains many beneficial enzymes and helps to boost immune health, as it is a powerful antioxidant. It is also anti-inflammatory and antibacterial, making it the perfect base for a homemade cough syrup.

How long can you keep honey and onion cough syrup?

Honey and onion cough syrup can be stored in the refrigerator for up to 1 week if the onions are left in the syrup. If you strain the onions, you can expect a storage time of anywhere from 2-6 months. Be sure to discard if there are any signs of spoilage such as an off smell or color, or any growth or mold.

Can onion clear mucus?

Onion is an expectorant, meaning it helps to clear mucus. Expectorants lubricate your airways and help make a cough productive. A productive cough brings up excess mucus, allowing it to be cleared from the body. This helps you to recover more quickly from a cold, and prevent it from becoming worse.

Ingredients

  • 2-3 medium onions peeled and sliced into half-moons
  • 2 cloves garlic roughly chopped (optional)
  • 2-3 cups raw honey

Instructions

  • Add the sliced onions to a medium heavy-bottomed saucepan or dutch oven, along with the chopped garlic (if using).
  • Add enough honey to cover the onions. They do not need to be entirely submerged, but the honey level should be as high as the onions.
  • Turn the burner on low and allow the onions and garlic to soften, stirring occasionally.
  • Cook on low heat until the onions are soft and slightly mushy, about 1-2 hours. Stir occasionally to encourage even heating.
  • If your onions are still not very soft, you can increase the heat slightly to encourage them to release their juices. The goal is to keep the heat low to preserve the enzymes and benefits of honey.
  • Once the honey has been infused, turn off the heat and allow it to cool to room temperature.
  • Place the honey onion cough syrup in a glass jar, and top it with a lid once the honey is no longer warm.
  • Store in the refrigerator for up to 1 week with the onions and ginger, or strain off the onions and ginger if you would like to store for 2-6 months. Discard if there are any signs of spoilage such as mold or an off smell.
  • Take ½ – 1 teaspoon every 1-2 hours at the first signs of a cold. If you’re treating a cold that has already started, take 1 teaspoon 3-4 times per day.

Notes

IMPORTANT: Honey is not safe for babies under 1 year of age.

      I haven’t made it with a sous vide, but you generally want to keep it very low to avoid overheating the honey. Something under 90F is ideal.

    I’ve heated mine au-bain-marie in the slowcooker. added all the ingredients in a jar, just put the lid on top (not closed) to avoid condensation getting in and heated it for a few hours. I also added fresh thyme + ginger + cinnamon. It’s not yummy, but it’s not bad.. I just want this cold to be over with…

    Thank you for sharing this. I am excited to make this today as I woke up with a bit of a soar throat. I think I will try warming this in the crockpot. I am going to put the honey and onion in a mason jar and put it on a towel in the crockpot with water half way up the jar. hoping it works this way so I don’t have to monitor the stove. Do you think this would work ok?

    How much are you heating the mixture. Seems to be counterproductive to use raw honey only to heat it.

      The heat is very low, and with my temperature checks it was between 80-90F, which preserves many of the benefits of raw honey. Regular honey can be used too, or you can infuse the raw honey and onions at room temperature for 24-48 hours.

      If you leave the onions in the syrup you have about 1 week, or 2-6 months if the onions are removed.

    I made this today for my daughter, I used the simmer burner on my stove, on the lowest possible heat, but my onions did get hot. There was no boiling or anything, but hot to touch. Have I ruined it? I

      It’s probably totally fine! Some stovetops seem to run a little warmer than others, and cookware plays a role too. Heavy-bottomed saucepans conduct heat better, but thinner saucepans may cause things to get a bit too hot. If there was no boiling, you’re probably totally fine!

      Should be fine to have, but you won’t have the added benefits of raw (or low temp pasteurized) honey. There are still lots of benefits though!

    I am not sure if you eat the onion or just allow them to be in the honey to naturally provide what healing they offer, or do you eat the onion and honey.

      If serving to children I wouldn’t ask them to eat the onions – that’s a hard ask for them! The process pulls the properties of onions into the honey, so that’s good enough in my view. I generally discard the onions because I prepare a batch for the upcoming cold season, but if you want to eat the onions I think that would be totally fine.

      Oh yes, totally fine! The benefits of raw honey are in place until about 98ºF, and there are still some benefits if heated higher than that. Sometimes using a heavy-bottomed pan helps conduct the heat better and prevents it from getting too hot.

    The only thing about heating the honey is that by doing it that way you kill the live active enzymes. It kind of defeats the purpose of using raw vs pasteurized honey. Let it sit overnight and that should be enough to soften the onions and garlic. You can also chop the onions more finely. More surface area means more oils/compounds are released.

      Yes, many traditional recipes call for keeping the onions in the honey at room temperature. My preference is to heat it at a super low heat, which keeps many of the enzymes, but reduces the amount of time that the honey stays in the range where bacteria can grow. Different people have different comfort levels, and of course do things differently! This is the same method used by the herbalist Rosemary Gladstar, but many people leave the onions and honey at room temperature.
