Ingredients:
– 1/4 cup extra virgin olive oil
– 2 sweet yellow onions (sliced and quartered)
– 1/2 cup coconut sugar
– 1-2 tablespoons balsamic vinegar
– 1/2 teaspoon lemon zest
– pinch of kosher salt

Variations

One of the best things about this Onion Jam recipe is its flexibility! Feel free to play around with the ingredients based on what you have on hand or your personal preferences.

  • Add Some Spice: Toss in a pinch of red pepper flakes for a little heat that pairs wonderfully with the sweetness.
  • Herb It Up: Try adding fresh herbs like thyme or rosemary during the cooking process for an aromatic twist.
  • Fruit Fusion: Mix in some diced apples or pears for added sweetness and texture—perfect for fall flavors!
  • Smoky Touch: A dash of smoked paprika can give your jam a unique depth that complements grilled dishes beautifully.

How to Make Onion Jam

Step 1: Heat the Oil

Start by adding the extra virgin olive oil to a large cast iron skillet. Heat it over medium-high heat until it shimmers. This step is essential because hot oil helps cook the onions evenly and enhances their natural sweetness.

Step 2: Cook the Onions

Once your oil is hot, add the sliced onions. Let them cook undisturbed for about 15-20 minutes until they turn golden-brown. Stir occasionally! This slow cooking process allows the sugars in the onions to caramelize fully, creating that rich flavor we crave.

Step 3: Add Coconut Sugar

Next, sprinkle in the coconut sugar. Watch as it begins to melt into the onions; give everything a stir once it’s melted. The sugar adds sweetness and helps form that sticky consistency we love in jams!

Step 4: Darken Those Onions

Keep stirring those onions as they darken—another 5-6 minutes should do it. The darker they get, the deeper their flavor becomes. Just be careful not to burn them; we want rich brown color without any bitterness.

Step 5: Mix in Vinegar & Lemon Zest

Now it’s time to stir in balsamic vinegar, lemon zest, and that pinch of salt. These ingredients balance out the sweetness perfectly! Continue stirring until everything thickens up nicely—this should take just a few minutes.

Step 6: Taste & Adjust

Finally, give your jam a taste! Depending on how sweet you prefer it, feel free to add more coconut sugar if desired. Remember, this is all about making it your own!

And there you have it—your very own homemade Onion Jam! Enjoy this flavorful addition to your meals; I’m sure you’ll find countless ways to use it!

Pro Tips for Making Onion Jam

Making onion jam is a delightful experience, and with these tips, you can elevate your jam-making skills to the next level!

  • Choose the Right Onions: Sweet yellow onions work best for this recipe as they caramelize beautifully and create a naturally sweet flavor profile.

  • Patience is Key: Allow the onions to cook slowly and develop their color. Rushing this process can lead to uneven cooking and less flavorful jam.

  • Adjust Sweetness: Don’t hesitate to taste as you go! The amount of coconut sugar can be tailored to your personal preference; feel free to add more if you like it sweeter.

  • Utilize High Heat at the End: Crank the heat up towards the end of cooking to achieve that deep caramelized color. Just be sure to stir frequently to prevent burning.

  • Store Properly: If you make a larger batch, store it in an airtight container in the fridge for up to two weeks. You can also freeze it for longer storage, making it easy to enjoy whenever you need a savory-sweet addition!
