Ingredients You’ll Need

This recipe uses simple ingredients that you likely already have in your pantry:

* **Onions:** The star of the show! Yellow onions are my go-to for their balance of sweetness and sharpness. You can also use red onions for a slightly sweeter and more colorful jam. About 3 pounds of onions is the right amount.
* **Olive Oil:** Used for sautéing the onions and adding richness to the jam. Extra virgin olive oil is preferred for its flavor.
* **Sugar:** Granulated sugar helps to caramelize the onions and adds sweetness to the jam. Brown sugar can also be used for a deeper, molasses-like flavor, and I will include a variation below.
* **Balsamic Vinegar:** Adds a tangy and slightly acidic note that balances the sweetness of the onions and sugar. Red wine vinegar is a good substitute if you don’t have balsamic vinegar.
* **Dry Red Wine:** (Optional, but highly recommended!) This adds a layer of complexity and depth of flavor to the jam. Use a dry red wine like Cabernet Sauvignon or Merlot.
* **Fresh Thyme:** (Optional) Adds an herbaceous and aromatic note to the jam. Other herbs like rosemary or sage can also be used.
* **Salt and Pepper:** To season the jam and enhance the flavors.
* **Balsamic Glaze (Optional Garnish):** Adds an elegant touch.

Ingredient Variations

* **Type of Onion:** While yellow onions are a great starting point, feel free to experiment with different types of onions. Red onions will give the jam a beautiful color and a slightly sweeter flavor. Sweet onions like Vidalia or Walla Walla will result in a very sweet jam.
* **Sugar:** As mentioned earlier, brown sugar can be used in place of granulated sugar for a deeper, richer flavor. You can also use honey or maple syrup for a more natural sweetener, but the flavor will be slightly different.
* **Vinegar:** Red wine vinegar is a good substitute for balsamic vinegar. Apple cider vinegar will add a fruity and slightly tart flavor.
* **Herbs:** Experiment with different herbs to customize the flavor of your onion jam. Rosemary, sage, bay leaf, or even a pinch of red pepper flakes can add a unique twist.
* **Spices:** A pinch of ground cloves, cinnamon, or nutmeg can add warmth and complexity to the jam.
* **Fruits:** Consider adding diced apples, pears, or figs to the jam for a fruity and sweet element.

Equipment You’ll Need

* **Large Skillet or Dutch Oven:** A large, heavy-bottomed skillet or Dutch oven is essential for caramelizing the onions evenly.
* **Wooden Spoon or Spatula:** For stirring the onions and scraping up any browned bits from the bottom of the pan.
* **Measuring Cups and Spoons:** For accurate ingredient measurement.
* **Jars or Containers:** For storing the finished onion jam. Sterilized jars are recommended for long-term storage.

Step-by-Step Instructions

Now that you have your ingredients and equipment ready, let’s make some delicious onion jam!

**Yields:** Approximately 2 cups
**Prep Time:** 15 minutes
**Cook Time:** 45-60 minutes

Step 1: Prepare the Onions

* Peel the onions and cut them in half lengthwise. Then, thinly slice each half into half-moons. Try to slice the onions as evenly as possible so they cook at the same rate.

Step 2: Sauté the Onions

* Heat the olive oil in a large skillet or Dutch oven over medium heat. Add the sliced onions and cook, stirring occasionally, until they begin to soften and turn translucent, about 10-15 minutes. Don’t let them brown at this stage.

Step 3: Caramelize the Onions

* Reduce the heat to low. Add the sugar, balsamic vinegar, red wine (if using), fresh thyme (if using), salt, and pepper to the skillet. Stir well to combine.
* Continue to cook, stirring occasionally, until the onions are deeply caramelized and very soft, about 30-45 minutes. The onions should be a rich, golden brown color and the liquid should have reduced to a thick, syrupy consistency. Be patient! This step takes time, but it’s crucial for developing the rich, sweet flavor of the jam. Adjust heat if needed to prevent burning.

Step 4: Taste and Adjust Seasoning

* Once the onions are caramelized, taste the jam and adjust the seasoning as needed. You may want to add more salt, pepper, sugar, or balsamic vinegar to achieve your desired flavor profile. Remember, the flavors will intensify as the jam cools.

Step 5: Store the Onion Jam

* If you plan to eat the onion jam within a week or two, you can simply transfer it to an airtight container and store it in the refrigerator. For longer storage, it’s best to sterilize your jars and process the jam in a water bath. Instructions for both methods are below:

Storage Option 1: Refrigeration

* Allow the onion jam to cool slightly.
* Transfer the jam to an airtight container.
* Store in the refrigerator for up to 2 weeks.

Storage Option 2: Canning (Water Bath Processing)

* **Sterilize the Jars:** Wash the jars and lids in hot, soapy water. Rinse well and sterilize by boiling them in a large pot of water for 10 minutes. Keep the jars in the hot water until ready to use.
* **Fill the Jars:** Remove the sterilized jars from the hot water and fill them with the hot onion jam, leaving about 1/2 inch of headspace at the top. Wipe the rims of the jars clean with a damp cloth.
* **Seal the Jars:** Place the lids on the jars and screw on the bands until fingertip tight.
* **Process in a Water Bath:** Place the jars in a large pot of boiling water, ensuring that the water covers the jars by at least 1 inch. Bring the water to a rolling boil and process for 10 minutes.
* **Cool the Jars:** Carefully remove the jars from the boiling water and place them on a towel-lined surface to cool completely. As the jars cool, you should hear a popping sound, which indicates that the lids have sealed properly.
* **Check the Seals:** After the jars have cooled, check the seals by pressing down on the center of each lid. If the lid doesn’t flex, it’s properly sealed. If the lid flexes, it’s not sealed, and you should refrigerate the jar and use the jam within a few weeks.
* **Store the Canned Jam:** Store the sealed jars of onion jam in a cool, dark place for up to 1 year.

Serving Suggestions

Now that you have your delicious homemade onion jam, here are some ideas for how to enjoy it:

* **On Sandwiches and Burgers:** Spread it on your favorite sandwiches or burgers for a sweet and savory kick.
* **With Cheese and Charcuterie:** Serve it alongside cheese and charcuterie for a sophisticated appetizer.
* **As a Glaze for Meats:** Use it as a glaze for roasted chicken, pork, or beef.
* **With Vegetables:** Serve it with roasted vegetables like Brussels sprouts, carrots, or sweet potatoes.
* **On Crackers or Crostini:** Spread it on crackers or crostini for a simple and elegant snack.
* **With Eggs:** Top your scrambled eggs or omelets with a dollop of onion jam for a savory breakfast.
* **Pizza Topping:** Add a spoonful of onion jam to your homemade pizza for a unique and flavorful topping.

Tips for Success

* **Be Patient:** Caramelizing the onions takes time, so be patient and don’t rush the process. The longer you cook the onions, the sweeter and more flavorful the jam will be.
* **Stir Frequently:** Stir the onions frequently to prevent them from sticking to the bottom of the pan and burning.
* **Adjust the Heat:** Adjust the heat as needed to prevent the onions from burning. If they start to brown too quickly, reduce the heat to low.
* **Taste and Adjust Seasoning:** Taste the jam frequently and adjust the seasoning as needed. Remember, the flavors will intensify as the jam cools.
* **Use High-Quality Ingredients:** Using high-quality ingredients will result in a better-tasting jam.
* **Sterilize Your Jars:** If you plan to store the jam for more than a few weeks, it’s essential to sterilize your jars to prevent spoilage.
* **Don’t Overfill the Jars:** When filling the jars, leave about 1/2 inch of headspace at the top to allow for expansion during processing.

Recipe Variations

Here are a few variations to try to customize your onion jam:

* **Spicy Onion Jam:** Add a pinch of red pepper flakes or a chopped chili pepper to the jam for a spicy kick.
* **Bacon Onion Jam:** Cook some chopped bacon in the skillet before adding the onions. The bacon fat will add a smoky flavor to the jam.
* **Fig Onion Jam:** Add some chopped dried figs to the jam for a sweet and chewy texture.
* **Apple Onion Jam:** Add some diced apples to the jam for a fruity and slightly tart flavor. Granny Smith apples work well.
