Caramelized Onion Jam Recipe

Onion jam is surprisingly easy to make. The first thing you should do is get a few Mason jars to store it when you’re done. This recipe is to make a hefty two pounds of jam, so calculate how many you’ll need so you can pull it off the shelf and eat it whenever you want.

It’s better to roast the onion in the oven than by boiling it in water. The taste will be more distinctive. Either way though is fine. Some people even like to charbroil them. That’s up to you.


  • 2 pounds of onions
  • 1 pound of sugar


  1. Line the oven tray with aluminum foil. Peel the onions and wash them. Put them on the tray, drizzle them with olive oil and add a pinch of salt. Put the oven to 390º F and cook the onions 35-40 minutes. Turn them from time to time to make sure they’re roasting through.
  2. Take your roasted onions out of the oven and let them cool off for a few minutes. Meanwhile, fill a pot with three cups of water and the pound of sugar. Add the roasted onions to the pot and cook them on medium high for 30 minutes. Stir constantly to make sure they don’t burn or stick to the bottom. The mixture will thicken slowly and caramelize, turning a dark brown and start smelling delicious. Make sure they don’t burn: if they burn just the tiniest bit they’ll turn the whole pot’s taste.
  3. Let the mixture sit for ten minutes. During that time, it will thicken some more. Then we can start pouring the jam into the jars. If you want to keep them stored, you can heat them in boiling water. Once you’ve sealed them tightly, place them carefully in a pot with water. After you hear the canning “pop” that means they’re set!

This is a recipe for sweet caramelized onion jam. There are other versions. Some people like to use balsamic vinegar, butter and half a pound of brown sugar with the same amount of onions or even add a touch of honey.

Our way is much simpler and the characteristic roasted taste will come through with every bite. If you like mixing sweet and savory, trying out different flavors, this is the recipe for you!

Try it as a spread on whole wheat crackers (just like in the picture). A slice of goat cheese and a spoonful of onion jam. A delicious and original appetizer that will impress any guest.
