Bacon and onion jam is one of the best sweet, savory condiments that you can add to a burger or anything that goes with bacon. Picture the deep, smoky essence of a piece of crisp bacon joined by the slow sweetness of caramelized onions and a sweet whiff of brown sugar or maple syrup. This jam is great on a big juicy hamburger, slathered on toast, served with cheese or over grilled meats.
Perfect balance So much of bacon onion jam is about that great balance. Combined with sweet onions, salt from bacon meets caramelized sugariness to create flavor that’s rounded out with the subtle tang of either vinegar or bourbon. The end product is a sticky, jammy brew that’s deep-flavored and incredibly addicting.

Essential Tools for Cooking

Understanding Bacon Onion Jam

Bacon onion jam is not just a topping but rather the synergy between caramelized onions and crispy bacon, reduced into a thickly delicious sweet-savory spread. The secret is to cook them slowly, patiently: slowly enough so that the white of their flesh has turned to gold; painstakingly enough that they are meltingly soft and sweet; gently enough so that the dry spices warm at a gentle blush rather than getting scorched.
Vinegar or alcohol, such as bourbon, in the mix lends depth; it counteracts the richness of the jam and keeps it from tasting overly sweet. It’s a very versatile type of jam that may be used as condiment, appetizer or ingredient in other dishes, like allium flavoring to a more complex dish. This is another kitchen basics recipe once you get the hang of making it.
Preparing the Bacon
Begin by cutting thick-cut bacon into bite sized bits. In a large skillet over medium heat, add the bacon and cook just until it renders its fat and the pieces are golden brown but not too crispy.
Transfer the bacon to a plate and set aside, leaving the fat in the pan. Bacon fat imparts additional flavor to the onions and acts as a meaty cooking medium that infuses the jam with smoke. Make level to moderate heat pampering bacon, so as to not let the fat burn which makes a bitter flavor when cooked.
Caramelizing the Onions
Thinly slice the onions and add them to the skillet with the bacon drippings. Simmer for 20–25 mins over med-low heat, stirring occasionally, until she reaches this velvety texture. The onions will softly caramelize, browning to a golden brown and sweet, the sugars in them coming out.
Add sliced garlic for the last few minutes to avoid burning and also keep its fragrance. Caramelization is key — that’s the secret to bacon onion jam’s rich flavor and its jammy, umami-drenched texture. The patience here is what will give the jam its luxurious depth.
Adding Sweeteners and Acid
When the onions are caramelized, add the cooked bacon back to the pan. Add brown sugar, maple syrup or honey (if using) and balsamic vinegar. The sugar adds body to the mix, while vinegar lifts it all up and balances the rich, savory flavors.
If you want even more flavour and dimension extra bourbon or chili flakes can go in now. Stir often and cook for another 5–10 minutes, until the mixture thickens and is sticky, jammy. It should smell sweet, smoky and a little tangy at this point; that will mean the jam is done.
Adjusting Consistency
Feel free to add a small splash of water or broth if the jam seems too thick. If it seems too thin, keep simmering gently until you’ve cooked off the excess liquid. The point is spreadability, stickiness, mouth-coating perfection that looks basically perfect on toast, burgers or roasting meats.
Check seasoning, adding more salt, pepper or vinegar if necessary. It’s a recipe that balances sweet, salty and tangy in all the right ways for bacon onion jam.
Serving the Bacon Onion Jam
Serve warm or at room temperature bacon onion jam. It also tastes great on toasted bread, burgers, sandwiches, or cheese boards. It is also a great accompaniment to roasted vegetables, grilled meats or even as part of your breakfast with scrambled eggs.
For longer storing, once the jam has cooled, transfer it to an airtight jar and refrigerate for two weeks. Reheat gently before serving, the texture will at once become soft and jammy.
Tricks for the best Bacon Onion Jam


Cook onions over low heat for the best results, as this will help retain natural sweetness and avoid burning. For a sturdier texture and richer flavor, use thick-cut bacon. Also balance the jam with sweetness, from sugar or maple syrup, and acidity, from vinegar to keep it from getting too cloying.
It must be stirred often as it cooks to avoid sticking, or adjust the consistency by cooking it thicker or thinner. Adhering to tips gets you a jam that is luscious, full of flavor and versatile with the broadest range of hors d’oeuvre.
Variations and Enhancements
Bacon onion jam has many uses. Stir in fresh herbs such as thyme, rosemary or sage for aromatics. Add of bit of red wine or some bourbon for depth. Spice junkies can stir in chili flakes or smoked paprika to impart a mild kick to the jam.
For a pureed jam, pulse the jam in a food processor. This is a great one to use as a topping for crostini or spread on sandwiches, bringing the same punchy flavor in creamy, smooth form. These variations enable you to tailor the jam for various meals or flavor profiles.
