Why You’ll Love This Recipe
Easy to make: With just 2 ingredients you literally can’t go wrong whipping it up. The hardest part is waiting.
Effective: These ingredients have been used for generations and generations to relieve scratchy throats.
Versatile: This cough syrup can easily be varied for different flavors.
Tastes great: With honey as the base, even kids don’t mind taking a spoonful of this cough syrup.
Ingredients You Need
Pretty straightforward with only 2 ingredients so you should have everything you need!
Honey: Just any store-bought honey won’t do the trick here. You need to use raw, unpasteurized honey to maximize its effectiveness. And if you notice in the pictures, the honey is brown. This is because after chatting to a beekeeper last year I learned that buckwheat honey is the most effective honey at relieving cough and sore throat symptoms due to its potency.
Any onions will work for the cough syrup but the type of onion you choose will change the flavor a bit. Red onions will be spicier and sweet onions obviously sweeter. If you’re specifically making it with kids in mind, use a sweet onion so that the flavor masks a bit.

Important Tips
Make sure that the onions are completely covered with honey or it won’t break down. Know that kids under one shouldn't have honey.
As the homemade cough remedy sits, the honey will lose its thickness. This is what you want!
Know that you can’t mess this recipe up. The amounts don’t matter it’s just what you have on hand. So long as the honey coats over the onions, you’re good.
I would refrain from adding lemon juice to the mixture. Though lemon juice (and lemon zest) is amazing for coughs, adding a liquid to the honey could make it spoil earlier. if you want to mix in lemon juice, make it into the old-fashioned cough syrup recipe at the bottom of the post.
This cough syrup does have a faint onion taste, if you like a really really sweet profile, use more honey.
Fun hack: Use the leftover honey onion syrup in a stir-fry dinner or chopped salad so that there’s no waste! Whisk it with a bit of apple cider vinegar to make an easy salad dressing.
How To Store It
Once it's done sitting, store the honey onion syrup in a sealed jar in the fridge. Here, it will stay fresh for up to three weeks.
The other option would be to strain the onions out and then freeze the cough syrup in mini silicone molds. When you have a cough, pop out one of the molds and suck on the honey.
How To Make Homemade Honey Onion Syrup


Step 1: Chop the onion and put it into the bottom of a wide-mouth jar.
Step 2: Pour the honey over top and make sure it coats the onion.


Step 3: Put a lid on it and let it sit for 24-36 hours, you’ll notice it starts to get more liquidy.
Step 4: Pour the mixture through a fine mesh sieve to strain out the onions. Keep the liquid honey and use it as needed.
Hack: if you’re short on time and don’t want to wait for the onions to break down the honey, place the jar in a small pot of water over low heat. Let it sit for an hour or so stirring frequently until the onions break down. Don't heat it up too much though or you'll destroy the antibacterial properties of the honey.
How To Use It
You can use this honey onion syrup a few different ways:
With coughs: Take a spoonful a few times a day if you feel a scratchy throat starting.
Frozen: Freeze the honey cough syrup in small silicone molds so that it’s cold if you have a really bad sore throat. This is what I do with my homemade cough drops.
As a dressing: I whisk this honey syrup in with my Fire Cider and drizzle it on salads for lunch. It’s the BIGGEST antibacterial, immune-boosting, gut-loving punch. Nice flavor too.
A quick reminder that babies under one shouldn’t be given honey. Use this for yourself and older kiddos.

Variations
You can adjust this 2 ingredient cough syrup as needed with a few of the swaps below.
Garlic: Add 1 tablespoon of chopped garlic to the mix and strain out like you do the onions. Know that the flavor of the syrup won’t be as sweet but it will have more anti-bacterial benefits.
Ginger: Another great ingredient for the immune system, add 1 tablespoon of grated or sliced ginger in with the onions.
Herbs and spices: You can easily spice up the cough honey with different herbs or edible weeds to give it unique benefits and tastes.
Cinnamon: Either infuse a cinnamon stick into the honey with the onions or add ground cinnamon to the honey mixture before your store it in the fridge.
