Onion Jam is the jam! Caramelized onions, sweet California prunes, and spices reduce down into a heavenly condiment that goes well with so many things!
This Onion Jam is, well, the jam. I’m so in love with this condiment that I’ve been putting it on all the things.
Several months ago while on a retreat hosted by the CA Prune Board, they served some prune onion jam and it was all anyone at my table could talk about. I tried replicating the recipe from memory and this is it…and it’s amazing.
Ingredients for this Prune Onion Jam Recipe
- Sweet onions
- Prunes
- Low-sodium chicken broth
- Sugar
- Honey
- Balsamic vinegar
- Ground ginger and fresh thyme
- Salt and pepper
- Vegetable oil
Prunes are so underutilized – you’d be surprised how many recipes are enhanced with just a few, or how well they pair with other ingredients. Onions and prunes are a fabulous combination. With added spices, this jam ends up smooth, sweet, vinegary, and a spread with endless possibility.
How to Use Onion Jam
- Spread some on a grilled cheese with Monterey Jack or Fontina cheese. Holy yum.
- Pair it with goat cheese and prosciutto on crostini. Easy appetizer!
- Top ricotta or cottage cheese with a little dollop. Hello breakfast.
- Stir it into warm pasta for an easy sauce. Yeeessss.
- Use it on a baked brie wheel…and watch everyone fight over it.
- Put it on puff pastry with ripe pears. Delicious!
- Serve it with steak, chicken, or pork. Love love love.
- Slather it on a burger. So good!
- Stand at the counter and eat it with a spoon. Wait, what?

How To Make This Prune Onion Jam Recipe
Onion Jam
Ingredients
- 3 tablespoons vegetable oil
- 1 pound sweet onions, , finely diced
- 1/4 teaspoon freshly minced thyme
- 1/4 teaspoon kosher salt
- a few turns of freshly-cracked black pepper
- 1/2 cup low-sodium chicken broth
- 2 tablespoons granulated sugar
- 2 tablespoons honey
- 3 tablespoons balsamic vinegar
- 1/4 teaspoon ground ginger
- 1/2 cup finely diced prunes
Instructions
- In a medium-sized saucepan, warm oil over medium heat; add in the onions, thyme, salt, and pepper. Cook until onions are soft and translucent, stirring frequently, about 10 minutes.
- Add broth, sugar, honey, vinegar, ginger, and prunes to the pot; continue cooking, stirring frequently, until onions begin to caramelize and prunes break down, about 10-15 more minutes.
- (While cooking, continue to stir to prevent scorching. If the mixture seems to be a bit dry, add a small splash of water toward the end. Do not overcook! Onions should be caramelized and there should still be a little bit of juice in the pot when it’s ready.)
- Let jam cool, then transfer to a lidded jar and store in the refrigerator.

My husband an I love this recipe…when I get to one jar in the freezer it is made right away! I also LOVE prunes..so that’s a plus too!
This looks so good! Would it be possible to can this? I’m thinking about giving some away as gifts.
Hi there Mairi! This recipe wasn’t developed to be shelf stable and I’m not an experienced canner, so I can’t say for sure. But as you can see from the storage notes, it does keep well in the fridge and freeze for long enough to give as gifts. I would love to receive some! HA.
I just made this tonight to go with turkey burgers and I’m glad I did. This jam is very tasty. I wish I made more.
This looks soooooooo good. Gotta make this one for sure. Definately gonna be a keeper no doubt. Yummmmmmmmmm
