Anolon® Cookware Giveaway

But before you get distracted by the prospect of prizes galore, let’s talk onions.

Or, more specifically, onion jam.

It’s unlike any jam you’ve had before. Rich and savory, with a hint of sweetness and verdant rosemary, this jam would make an excellent side on your holiday table. Serve it with biscuits or toast; spread it on your turkey, swirl in in your mashed potatoes. It’s a versatile spread that’s part condiment, part sauce, and entirely delicious.

Balsamic Rosemary Onion Jam

You know what’s amazing? Goat cheese biscuits with onion jam, that’s what. *Drops mic*

Balsamic Rosemary Onion Jam

What starts as almost 10 cups of sliced onions cooks down to a sweet, sticky jam. It may seem like a measly amount for all that time and effort, but that’s before you taste just how much flavor is packed into each bite.

Balsamic Rosemary Onion Jam


  • 2 tablespoons olive oil
  • 4 large onions, thinly sliced (about 10 cups sliced)
  • 3 tablespoons balsamic vinegar
  • 2 tablespoons brown sugar
  • 1 1/2 teaspoons finely chopped fresh rosemary or 1/2 teaspoon dried rosemary
  • 1/4 teaspoon kosher salt
  • 1/4 teaspoon freshly ground black pepper


Preheat oil in a large skillet over medium heat. Add onions. Cook, stirring occasionally, until onions are soft, translucent, and just beginning to brown, about 20 minutes. Stir in balsamic vinegar, brown sugar, rosemary, and salt and pepper. Continue to cook, stirring occasionally, until liquid is evaporated and onions are dark brown and reduced to 3/4 cup, about 40 minutes more. Remove from heat and let cool. Store in a glass jar or airtight container in the refrigerator for up to 1 week.

  1. I would make this scrumptious onion jam my own by using it in an upscale version of the classic Philly Cheesesteak.

  2. I’d add red pepper flakes… and call it screamin. 

  3. I would add a little bacon to it and serve it on burgers or chicken.

  4. I subscribe

  5. First, I would use Vidalia sweet onions; and the finished product would be amazing on some little rye rounds with thinly sliced beef tenderloin and some blue cheese crumbles… Forgive the drool on the screen…

  6. Changing up the herbs and using different vinegars would be a good start

  7. I follow on Twitter

  9. I would mix it with sour cream to make a dip.

  10. I would eat it on the goat cheese biscuit…hello! Genius! But also maybe a hot onion dip? Yummmm….

  29. I think this onion jam would make a great pizza base years ago Stonewalls kitchen sold their goods at a local farmers market(before they became huge) They made an awesome onion jam which I used as a pizza base. That still carry it but it’s not the same. Can’t wait to try yours!
    Thank you

  30. I am a happy Pinterest Love and Olive Oil follower!

  31. I would make this recipe more “mine” by adding some red pepper flakes to give it a little heat…then I would use it as a topping to a grilled chicken breast…yum!

  32. I would use less rosemary and smear it on top of a burger

    I love the onion jam recipe, I would put it over chicken, yum!

  36. I think I’d leave the recipe as is.  I would use it on bland crackers.

  37. I’m a subscriber

  38. already subscribed!

  39. I instantly envisioned this as a bruschetta topping with roasted red pepper and fresh mozzarella! A little prosciutto would be good on there, too! YUM!!

  40. I’d love to try this on some crusty bread with baked garlic brie.

  43. If that glorious concoction doesn’t deserve to go on pizza, I don’t know what does! I’m almost drooling. At least I know what we’re having for dinner! ;)

  44. I would spice it up with some chipotles.

  45. I subscribe to your newsletter.

  46. My first thought when you said ‘jam’ was to add grape jelly to the mix… I don’t know if that would taste good or not though. Your recipe is probably delicious without any other additions though….might even try it out in my Christmas menu!

  47. I already subscribe to your newsletter! (under the same email I’m commenting with) which is actually how I learned about this fantastic giveaway! thank you for this awesome opportunity, I’ve been using the T-fal cookware I got in 1988 and it’s high time they were replaced!!

  52. I think it would be good served on some good sourdough bread with cheese on top and then put under the boiler to make the cheesy bubbly. Like french onion soup but without the broth!

  53. I follow on Pinterest!

  54. That looks delicious! I think that needs to go on my next burger or in a grilled cheese

  63. I’d use it in an eggplant lasagna. Layer noodles, ricotta, onion jam, noodles, fried eggplant, mozzarella, noodles, slather the top with a bit of tomato confit and sprinkle with parmesan. Yum!

  64. I think I would make the jam the same way but instead of goat cheese biscuits I would serve it over goat cheese and serve on crackers.  I love a little crunch.

  65. The jam sounds scrumptious. I think I would pair it with a roasted pork tenderloin or even top a pulled pork sandwich with it. Yum! Thanks for the chance!

  66. Followed Pinterest: @jspepper

  67. Yep, I already subscribe.

  68. To make it my own? I’d add more brown sugar to give it a sweeter taste, And I’d test out Sriracha to see what it would do with it. 

  69. I love the idea of this flavor combination but would like to figure out a way for it to be part of an actual spreadable jam consistency.

  70. I am already subscribed!

  71. You don’t say what type of onions you are using. I would use Vidalia onions and cook them slowly and at low heat until carmelized for the Onion jam.

  72. I am already subscribed to your blog. Good recipes so far.

  73. I think this would be delicious on sandwiches or homemade pizza!

  74. I am following Anolon and Love and Olive Oil on Pinterest.

  75. I am following Love and Olive Oil and Anolon on Twitter. Tweeted.

  76. I would use the large white sweet onions and cut back on the brown sugar. I love the recipe! 

  77. I would add the onion my tortilla de patata. That would make it amazing and give a little sweetness and tartness to starchy dish.

    Thanks for the giveaway!!

  92. I would love to use this onion jam as an accompaniment to some sort of roast beef.  Maybe as a spread to bake with a roast, covered in foil, so the juices can seep into the meat and it can be served after carving.  YUM!!!!

  93. The onion jam looks fabulous. The photos make me crave some French onion soup too. I might add a little balsamic vinegar, but will have to try it straight first.

    • I must have had a blind moment as I totally missed the vinegar in the recipe! I do have fig balsamic that I might try too
