Onions don’t get enough credit, in our opinion, which is why we plan to give them top billing on all future cheeseboards, crostini, and burgers with this recipe for Sweet Onion Jam. Equal parts sweet and savory, this onion-based condiment is the perfect way to use up lots of onions at one time.
What types of onions can be used in this Sweet Onion Jam recipe.
Not all onions are created equal, especially when it comes to recipes like this one. While white onions are great for salsa and red onions are perfect for grilling, sweet onions are where it is at when it comes to making recipes like this jam, caramelized onions, and onion rings.
Here are the types of onion that will work in this Sweet Onion Jam recipe and why:
Yellow Onions
Yellow onions are typically called for the most in recipes since they aren’t as strong aswhite onions. They do havea sharp, astringent flavor similar to white onions, just not as intense. Yellow onions have a subtle sweetness that makes them a perfect choice for both savory and sweet recipes like this jam.
When cooked, yellow onions lose their sharpness and become sweeter which makes them perfect for making recipes like caramelized onions. They are the perfect onion for soups and sauces since they have a robust, deep flavor.
Sweet Onions
These onions are very similar to yellow onions. They are very sweet without being pungent. They are great for deep frying and roasting as well as for other popular onion recipes.
What are sweet onions used for? Sweet onions are used in popular dishes like the Blooming Onion and French Onion Soup.
What are the different types of sweet onion? Maui, Vidalia, Bermuda, Texas, and Walla Walla Sweets, just to name a few. Sweet varieties of onions lack the sulfuric kick of white or red onions and won’t make you cry when you cut them either! Sweet onions are the best onions for burgers. You just can’t beat a slice of raw, sweet onion on top of a juicy burger.
Spanish Onions
Often confused with yellow onions,Spanish Onionsaresweet and havea lower water content than many onions, making them the best onion for making onion rings!
How to make Sweet Onion Jam
This recipe is so easy that even a beginner could make it. It requires very minimal ingredients and can be swapped up based on what ingredients you happen to have on hand. No white wine vinegar? Use white balsamic. No rosemary? Use more thyme. Have allspice leaves? Swap them out for the bay leaf. The sky is the limit here, be sure to go for it!
Gather and prep the ingredients.
You don’t need much to make this onion recipe; sweet or yellow onions, olive oil, thyme, rosemary, bay leaf, and white wine vinegar.
It is important to get everything completely prepared before you start cooking, as it all happens pretty quickly once you get going.
Cook to soften and season.
In a large pot, cook the onions in hot oil over moderately high heat until golden brown, about 15 minutes.
Bundle the herbs together with kitchen twine and add them in with the cooked onions, stirring until fragrant.
Smother it in sugar
This step will seem weird. I’m not even going to lie about it. Sprinkle the sugar entirely over the top of the cooked onions, reduce the heat to low, and don’t touch it.
Don’t stir, don’t shake, don’t even poke! Leave those onions alone until the sugar has all been melted and is a bubbling liquid.
Now crank the heat to high and watch the sugar caramelize right before your eyes!
Stir in the vinegar and let everything “jam” up over low heat, literally.
Take a trip to flavor town!
Once this glorious Sweet Onion Jam has cooled, you are ready to do just about whatever your heart desires with it. Just remove the herb bundle and discard it first. No one needs to be chomping down on that!
