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.

  2. I’d try this as an appetizer… small toasts with a triangle of tart apple (grannies, prop), a dollop of jam, topped with a bit of goat cheese… all warmed for a few to get the cheese a little melty.

    Can’t wait to make this!

  3. I’d put it in a grilled cheese sandwich, yum!

  5. Subscribed via email, tweeted too! Can you tell I’m motivated?

  6. Oops, tweeting was supposed to be a separate comment. Its early…

  7. I’d maybe add a little port to the onion jam and serve it on grilled beef tenderloin. I love onions & caramelized onions, but have never gone as far as “onion jam”. Can’t wait to try this


  8. I would put it on my deep dish pizza.

  9. Put it in a pasta dish with creme, tomatoes and a little balsamic!

  10. Oh my goodness – it looks amazing! Put some in a little sour cream and I’m sure it would beat any onion dip anywhere!!!!!!

  11. I am planning on serving this with scrambled eggs, caviar and toast points for New Years Eve Midnight Brunch…with champagne of course!

  12. I would probably have it first on a cheeseburger (with bacon jam, too.) The possibilities are practically endless! (I LOVE onions, especially sweet onions.)

    Thanks for a chance at the giveaway! I’d be thrilled to win! Happy Holidays!

  14. I already followed loveandoliveoil on Pinterest and now follow Anolon as well. My user name is dh127.

  15. I’d add some white wine with the balsamic and spices. Love onions, balsamic and wine together.

  16. I’d put a spoonful in the egg base of a frittata (parm + roasted tomato or artichoke + prosciutto). That way I’d spread the goodness.

  21. Chipotle onion jam on grilled cheese, anyone? 

  22. Spread on a pizza crust. Meanwhile, mix together cream cheese and feta cheese, drop chunks of the mixture on top of pizza and bake until cheese is a little browned. 

  23. grilled cheese sandwich!

  25. Gish – wouldn’t it be yummy with some cold ham? Or with some crusty bread and a chunk of cheese? Yum.

  26. I’d add  bacon or pancetta!  then, feeling ambitious,  I’d  make  some kind of savoryrugelach  with this and some crumbled  goat cheese.

  31. I am hosting my office Christmas party this evening at my house.  I cooked 2 bottom round roasts in my Crock Pot overnight  – Balsamic Roast Beef recipe I found on Pinterest –  and will be shredding the meat and putting back in the  Crock Pot with the remaining juices for warm sandwiches. I think I just found one more recipe to whip up today!  I will make the onion jam “as is”  for the perfect accompaniment to the  Balsamic Roast Beef Sandwiches.   I am so glad I saw this post this morning!

  34. I want to put this on pizza. With bacon and goat cheese. Yum.

  37. I would add in some bacon fat for a more in-depth flavor. *fingers crossed*

  41. On a burger with a nice buttery toasted bun 

  42. I actually have a recipe for a tomato and onion chutney that I posted in the summer at the height of tomato season. I didnt add balsamic (but love it and eat a little on my roasted squash every night lately) and your creation is PERFECT! Must.try.  Great giveaway, too!

  43. I’ve never even tried onion jam before, so I’d love to try it your way before messing around with what I’m sure is a very good thing :)

  44. I instantly thought this would taste great smothered on grilled chicken! 

  45. I would add bacon and use it as a burger topping along with bleu cheese!

  46. I would try serving it with salmon! Yum!

  47. I subscribe by email!

  48. I’d use it on burger dips! Burger dips are like a French dip sandwich, but with hamburger and Swiss cheese…use this jam, too, dip in au jus…delicious!

  49. I would actually throw some cranberries in. yum!

  53. I’d add a little heat – some crushed red pepper flakes or jalapeno olive oil or cayenne pepper. I think it would go nicely with the tartness of the balsamic and the sweetness of the onions, and give it a little kick as well. Amazing giveaway – thank you!

  54. In reading your recipe, I don’t see anything I would change.  Can’t wait to try it!!

  55. I also follow you on Pinterest – megjoneswall

  56. I think this would be really tasty in a Chinese bun as a filling. Or even dumplings/potstickers!

  57. I would add Cayenne pepper to add some spice and maybe a tablespoon more of brown sugar to give it the perfect sweet and spicy combo!

  58. I’d add just a pinch of ground ghost pepper to give it a kick of heat

  59. I’m already subscribed

  60. I would use a flavored balsamic like cranberry balsamic for the holidays and serve on crostini with goat cheese

  61. I’d put the jam on pizza with a bit of goat cheese. Yummy!

  66. I would most definitely, and I am pretty much repeating you here, pair it with my favourite biscuit recipe – Elise @ Simply Recipe’s buttermilk goat cheese and chive biscuit.  I think this is just going to have to make the list for my Christmas brunch! 

  67. I would add it to our “breakfast for dinner” meals, on a biscuit.

  68. This sounds delicious! I know my family would love it. I’m thinking it would be a great addition to a grilled cheese. Yum. And those pans look amazing!

  69. I would make a BLT with sprouted grain brain and spread the onion jam on it to make a BLTO!

  71. Maybe a balsamic, strawberry and onion jam?! 

  72. I’m seeing this on a fresh baked biscuit with some brie!

  77. I love onion jams, I always put it on a sizzling steak, but I’m a bit of a naturalist and have never actually tried it with balsamic, but it sounds amazing!

  78. I follow both on Pinterest.  Username:  Jan

  79. I would substitute Agave syrup for the brown sugar. I have had good results using agave syrup in my jams.

  80. I could see this being really amazing in a bake brie en croute!  Perfect for the holidays!

  81. This onion jam would be absolutely terrific over some fresh croissants that have been baked with a little young gruyere inside.
    Or I can imagine doing a fresh everything bagel toasted with just a bit of plain cream cheese and onion jam.
    This recipe is awesome either way, so thanks for sharing!

  82. I would package in little jars and give to holiday guests to take with them.

  86. I have a mild obsession with onions….I actually always have that big bag of giant onions from Costco at home (and I live alone!)
    I wouldn’t change this dish at all. Perfection! 

  87. Try a different herb like thyme and add garlic

  88. This sounds great – if only could get someone to slice up all those onions for me.

  93. My husband makes some really good grilled chicken with onion so I think this would taste great on his grilled chicken. 

  94. I would make it into french onion soup.  Onion jam makes the best soup, no stock required.

  95. I subscribe to your emails.

  96. I would add a little heat to it by adding some jalapeno to it!

  97. Sounds great all ready but I may add some mustard seeds
