caramelized onion bacon burger

This Caramelized Onion Bacon Burger delivers great flavor with each and every bite.

Everybody loves a bacon burger, right?  I know I do.  A perfectly grilled burger, with some smokey bacon on top, and caramelized onion?  Yum.  Of course, it can also become a slippery mess.  So I thought, why not put the onions and bacon inside the burger.  So I did.  And it is good.

How to caramelize onions

To caramelize the onions; heat 1 tablespoon extra virgin olive oil and 1 tablespoon unsalted butter in a small skillet over medium-low heat. Add the onion and cook, stirring occasionally, until well browned; about 15 – 20 minutes. If you are not cooking the burgers immediately, allow the onion to cool before adding them to the meat.

This Caramelized Onion Bacon Burger delivers great flavor with each and every bite.  And, added bonus, you can make these in advance, take them to your cookout, throw them on the grill and eat them, all in one easy step.

Caramelized Onion Bacon Burger


  • 1 pound 20% lean ground beef
  • 4 ounces thick applewood bacon, cooked and chopped
  • 1 large onion, diced and caramelized
  • Salt and freshly ground pepper, to taste
  • 4 slices of your favorite cheese (I like to use fontina with this burger)
  • 4 hamburger buns
  • 1 tablespoon extra virgin olive oil
  • Arugula
  • 1 recipe Sun-Dried Tomato Aioli, recipe follows
  • Sun-Dried Tomato Aioli

  • 1 ounce drained sun-dried tomatoes (packed in oil)
  • 1 small clove garlic, minced
  • 1/2 cup mayonnaise
  • 2 tablespoons grated Parmesan cheese
  • 1/2 teaspoon balsamic vinegar
  • Salt, as needed


Step 1

In a large bowl mix together the meat, bacon, and caramelized onion along with salt and freshly ground pepper, to taste. Form into four patties.

Step 2

Heat your BBQ or grill to medium- hot, add the burgers and cook until browned on one side, flip and brown the other side. When almost cooked; place a slice of cheese on top and allow to melt.

Step 3

Meanwhile, lightly coat the bun with olive oil. Place on the grill, cut side down and allow to heat. The bun should remain soft, and be lightly browned.

Step 4

Place the burger on the bun, spread 1 tablespoon of the aioli on the top half of the bun, place a mound of arugula on the burger, top with bun and serve.

Step 5

Prepare the Sun-Dried Tomato Aioli:

In a food processor, pulse the sun-dried tomatoes with the garlic until finely chopped, then puree until smooth. Add the mayonnaise, Parmesan and balsamic, pulse until blended. Taste and adjust for salt as needed.
