What Is Caramelized Onion Jam Savory and Sweet?
Caramelized Onion Jam is a luscious preserve that balances the deep umami flavors of onions with a touch of sweetness. Traditionally originating from various cuisines, this jam uses low and slow cooking methods to coax out the sugars in the onions, resulting in a texture that is both soft and spreadable.

Whether served on a toasted baguette with cheese or layered within a savory tart, each bite offers both taste and experience.

Ingredients You’ll Need
- Onions: 4 large yellow or sweet onions. Onions serve as the base for the jam, providing flavor and texture. You can substitute with red onions for a sweeter taste or shallots for a milder flavor.
- Butter: 2 tablespoons unsalted butter. The butter enriches the texture and aids in the caramelization, giving a smooth finish. Olive oil can be used as a dairy-free alternative.
- Balsamic Vinegar: 1/4 cup. This adds acidity and depth of flavor that balances the sweetness of the onions. Apple cider vinegar can also be used for a slightly different profile.
- Brown Sugar: 2 tablespoons. Brown sugar enhances caramelization and adds a rich sweetness that complements the onions. You can swap it for maple syrup for a unique twist.
- Salt: 1 teaspoon. A necessary seasoning to enhance flavors and help draw moisture out of the onions.
- Pepper: 1/2 teaspoon. To taste; it adds a subtle heat that rounds out the flavor profile.
- Fresh Thyme: 2-3 sprigs. This herb adds a fragrant nuance and works beautifully with the sweetness. Dried thyme can be used in a pinch, though fresh is recommended.
How to Make
- Prepare the Onions: Begin by peeling and slicing the onions thinly into half-moons. A sharp knife is crucial for this task, as it ensures uniform slices that will cook evenly. If you find yourself tearing up while cutting onions, try chilling them beforehand or using a sharp knife to lessen tears.
- Heat the Pan: In a large, heavy-bottomed skillet, melt the butter over medium heat. Choosing the right pan is critical; non-stick or cast iron skillets work best because they distribute heat evenly, preventing the onions from sticking and burning. Once the butter is fully melted, it will smell fragrant and foamy.
- Add Onions and Salt: Once the butter is melted, add the sliced onions and sprinkle with salt. Stir to coat the onions evenly; this initial salting helps draw out moisture. Stirring frequently, allow the onions to soften and begin to develop a translucent appearance, which usually takes around 10-15 minutes.
- Caramelize: Lower the heat to medium-low, and let the onions cook down slowly. This process can take 40-60 minutes. Stir occasionally, scraping up any browned bits from the bottom. As the onions cook, they’ll darken and become sweeter. This is the time to be patient; good caramelization cannot be rushed!
- Add Sugar and Vinegar: Once the onions have turned a beautiful golden brown, sprinkle in the brown sugar and pour in the balsamic vinegar. Stir well to combine, this step enhances the sweetness and adds a lovely tang. Allow the mixture to simmer for another 10-15 minutes, stirring occasionally.
- Finish with Thyme and Adjust Seasoning: Stir in the fresh thyme, pepper, and taste to adjust with additional salt or sugar as needed. The jam should have a harmonious balance of sweet and savory. If it’s too thick, a splash of water can be added to reach the desired consistency.
- Cool and Store: Once fully cooked, let the jam cool slightly before transferring it to a sterilized jar. Cooling is essential as the consistency will thicken as it cools. Seal the jar and store it in the refrigerator. This jam can keep for up to two weeks, if not longer!
Variations & Substitutions
Sweet and Spicy Variation
For those who enjoy a little heat, consider adding red pepper flakes during the cooking process. Just a pinch will add a delightful kick without overpowering the other flavors. This variation is perfect for topping grilled meats or blending into barbecue sauces. You can also experiment with adding minced garlic in the last few minutes of cooking for an additional flavor boost that complements spicy notes beautifully.
Herb-Infused Variation
To add depth, consider incorporating different herbs like rosemary or sage. Rosemary’s pine-like flavor can make the jam more aromatic, while sage can lend an earthy undertone. Add these herbs during the last 10 minutes of cooking so their essence transfers into the jam. Not only will this enhance the flavor, but it also gives a beautiful aroma that will fill your kitchen.
Red Wine Variation
If you’re a wine enthusiast, substituting some of the balsamic vinegar with red wine can impart another layer of complexity. The acidity from the wine will also help balance out the sweet notes from the caramelized onions and sugar. Make sure to allow the wine to cook down sufficiently to eliminate the raw taste, leaving you with a rich, indulgent jam.
Cranberry Addition Variation
For a seasonal twist, consider adding dried cranberries to the onion mixture midway through the cooking process. Dried cranberries will plump up slightly and add a tart contrast to the sweet onions. This variation is especially popular around the holidays, where it can serve as a vibrant condiment to dishes like turkey or pork.
Common Mistakes to Avoid
One of the most common pitfalls when making Caramelized Onion Jam is cooking the onions too quickly. If the heat is too high, you risk burning the onions rather than caramelizing them. A critical tip here is to keep the heat at medium to medium-low, allowing the natural sugars to caramelize rather than char. Remember, patience is key!
Another mistake is not slicing the onions evenly. Inconsistent sizes lead to uneven cooking, with thicker pieces remaining crunchy while thinner ones may disintegrate. Always aim for uniform slices to ensure a consistent texture throughout your jam.
Lastly, skipping the salting step is a major oversight. Salting helps draw out moisture and ensures the onions cook down properly and release their natural sugars. This step not only promotes caramelization but enhances the overall flavor of the jam.
Storage, Freezing & Reheating Tips
Storing Caramelized Onion Jam properly is crucial for maintaining its freshness. After allowing it to cool fully, transfer the jam into an airtight glass container, and make sure to refrigerate it promptly to minimize spoilage. It’s best consumed within two weeks, though it may last longer depending on how well it was sealed.
For longer-term storage, you can freeze the jam. Portioning the jam into ice cube trays allows you to thaw only what you need later. Once frozen, transfer the cubes into a freezer-safe bag, removing as much air as possible to prevent freezer burn. When you’re ready to use it, simply thaw the desired amount in the refrigerator overnight or heat it gently in a saucepan.
In terms of reheating, a low simmer on the stove works best. This will return its spreadable consistency without altering the flavor, as microwave heating can unevenly warm the jam, resulting in a change in texture and taste.
Frequently Asked Questions
Can I use other types of onions for this recipe?
Yes! While yellow onions are traditional for caramelizing due to their balanced sweetness, red onions can provide a sweeter result for those who prefer a milder flavor. Shallots can also be used for an even more delicate taste. Each type of onion offers a unique flavor profile, so feel free to experiment according to your preference.
How can I make a vegan version of Caramelized Onion Jam?
Making a vegan version is easy! Simply substitute the unsalted butter with olive oil or coconut oil. Both options serve the same purpose and will yield delicious results. Ensure that any additional sugar used is also vegan-friendly, as some sugars are processed using animal bone char.
Can I can this jam for longer shelf life?
While canning is a great way to prolong the shelf life of preserves, it is essential to follow sterilization processes and ensure the right acidity levels. You may need to add a bit more vinegar for safe canning practices. For detailed instructions, always refer to reliable canning resources like the USDA guidelines.
