Balsamic Onion Burger

This 30 Minute Balsamic Onion Burger is a great twist on a classic burger. The onions on this burger are addictive. You caramelize the onions in butter until golden, then they are coated in a sweet and savory balsamic glaze. Paired with provolone, arugula, and mayo, this is a burger you’ll love.

I made the recipe is pretty simple, it has 9 ingredients, and only takes 30 minutes to make. I like to pair it with chips for a quick and easy dinner.

How to make Balsamic Caramelized Onions

  • Slice your onions so they are about 1/2“ thick.
  • Melt butter in a large skillet for medium heat and add in your onions.
  • Cook for 12-15 minutes, stirring every few minutes. If they start to burn, lower the heat.
  • Once the onions are soft and golden add in balsamic vinegar, brown sugar, and a pinch of salt.
  • Cook until the sauce has reduced to a thick syrup.
  • Transfer to a bowl and set aside while you make the burger. You can make the onions up to 4 days in advance

Once you have the onions out of the way the burger is pretty easy to make. The patty itself is just seasoned with salt and pepper. I also wanted to keep the topping simple to let the onions shine. Peppery Arugula, mild provolone, and mayo are the perfect pairing for this sweet and savory burger.

Do you have questions?

Why do you add sugar to the caramelized balsamic onions?

Onions are naturally sweet and will caramelize when you cook them over low heat for an extended period, usually about 45 minutes. To shorten the cooking time on the onions and to balance out the balsamic vinegar I added 2 tablespoons of brown sugar to the onions.

Can the caramelized onions be made ahead of time?

You can make your caramelized onion up to 4 days ahead of time and store them in the fridge.
