There’s always that one thing on a charcuterie board that disappears quickly.
Not the baked brie. Not the crackers or crostini.
It’s the little jar of something dark, glossy and completely irresistible—the thing people keep going back for, asking “what is this?”
This Bacon Onion Jam is that thing.
This is one of those recipes that surprises people. It doesn’t look like much at first, but once you try it, you realize how many ways you can use it. It’s sweet, savory, smoky and just a little tangy, with slow-cooked onions and crispy bacon melted together into something that’s somewhere between a spread, a condiment and a secret weapon in your fridge.
What Is Bacon Jam?
Bacon jam is a savory-sweet spread made by slowly cooking bacon, onions and sugar together until thick and jam-like.
Even though it’s called “jam,” it’s not fruity or overly sweet. Instead, it has a rich, savory flavor with just enough sweetness to balance the saltiness of the bacon.
The result is a bacon spread recipe that’s:
• Smoky
• Slightly sweet
• Deeply savory
• Completely addictive
It’s most often used on burgers, toast or cheese boards—but once you try it, you’ll find endless ways to use it.
Why This Is More Than Just a “Jam”
Let’s be clear—this isn’t a breakfast jam.
This is a savory jam recipe that quietly transforms everything you put it on.
• Spoon it over a burger → instant upgrade
• Add it to a grilled cheese → next-level comfort food
• Serve it on a charcuterie board → everyone asks for the recipe
The Flavor Situation (It’s a Lot—in a Good Way)
This bacon jam recipe hits every note:
• Smoky from the bacon
• Sweet from brown sugar and caramelized onions
• Tangy from balsamic vinegar
• Savory from slow cooking everything together
The magic happens when it cooks low and slow long enough to turn into that rich, jammy texture.
How This Comes Together
This onion bacon jam one of those recipes where time does most of the work.
You’ll:
• Cook the bacon until crisp
• Sauté the onions until softened and lightly caramelized
• Add everything back in and let it slowly simmer
And then… you wait.
As it cooks, it thickens, deepens and turns into that glossy, rich jam that makes this recipe so good.
The Texture You’re Looking For
You’ll know it’s ready when:
✔ It looks thick and glossy
✔ Most of the liquid has cooked off
✔ It spreads easily but isn’t runny
Think: soft, scoopable and slightly sticky
What Makes This Version Stand Out
A lot of bacon jam recipes lean really heavy or overly sweet.
This one is a little more balanced:
• The onions are cooked until just caramelized—not overdone
• The balsamic adds brightness instead of just sweetness
• Mustard seeds give it a subtle pop of texture and flavor
• It’s thick and spreadable—but not greasy
It’s the kind of bacon jam that you can use in a lot of different ways, not just one.

Bacon Onion Jam
Equipment
Ingredients
- 16 ounces smoked bacon, chopped
- 6 cups chopped yellow onions (3 medium onions)
- ¼ cup balsamic vinegar
- ½ cup packed dark brown sugar
- ½ cup water
- 1½ teaspoons mustard seeds
- 1 teaspoon kosher salt
- ½ teaspoon ground black pepper
Instructions
- In a Dutch oven, cook the bacon over medium-heat, stirring occasionally, until the bacon is just crisp- 12 to 15 minutes. Remove the bacon with a slotted spoon, and drain on a plate lined with paper towels, reserving 1 tablespoon drippings in the Dutch oven.
- Add the onions to the hot drippings; cook over medium heat, stirring occasionally, until the onion is slightly caramelized, about 12 minutes. Stir in the cooked bacon, vinegar, brown sugar, water and mustard seeds. Reduce the heat to low, partially cover, and cook, stirring occasionally, until the mixture is the consistency of jam, 60 to 70 minutes.
- Remove the pan from the heat, and stir in the salt and pepper. Cool to room temperature, about 30 minutes. Store in an airtight container in the refrigerator for up to 1 week.
Notes
- Cook low and slow for best flavor and texture
- Stir occasionally to prevent sticking
- Don’t rush the process—this is where the flavor develops
- Store in the fridge and reheat slightly before serving
- Pairs well with cheese and meats
