Caramelized Onion Burger Stuffed with Blue Cheese


My new favorite creation is this Caramelized Onion Burger stuffed with Blue Cheese. Yes, the Arugula, Edamame & Fennel Salad I made earlier this week was pretty delicious, but this burger was just crazy good.

I wanted to make stuffed blue cheese burgers with caramelized onions on top, but then I had an idea… why not puree the caramelized onions and stir them directly into the meat? I was hoping the onions would keep the extra-lean ground beef moist and add a touch of sweet onion flavor – and I was right!  And there’s more… fresh basil, oregano and thyme flavoring every bite, and blue cheese just oozing out all over everything.

Hungry yet?
Here’s a suggestion. Start the weekend off with a big, beautiful burger! TGIF.

Caramelized Onion Burger Stuffed with Blue Cheese
Recipe Type: Entree
Author: A Passionate Plate
Serves: 6
  • 2 lbs. extra lean ground beef
  • 1 large sweet onion
  • 1 Tbsp. olive oil
  • 1 tsp. sugar
  • 2 Tbsp. chopped fresh herbs (oregano, basil, thyme)
  • 1 tsp. worcestershire sauce
  • 1/2 tsp. fresh ground black pepper
  • 4 oz. good quality blue cheese
  • 6 hamburger buns
  • avacado, tomato, arugula, mustard, mayo and other condiments of your choosing
  1. Slice the onion thinly. Heat the olive oil in a large skillet over medium-high heat. Add the onion and sugar and reduce heat to medium low. Sauté the onions, stirring frequently, until they are golden brown and well caramelized – about 15 minutes. Remove from heat.
  2. When onion has cooled, place it in a small food processor and pulse to a coarse puree.
  3. In a medium bowl, combine the ground beef, worcestershire sauce, fresh herbs, black pepper and the onion. Mix well.
  4. Divide the meat into 12 equal portions.
  5. Flatten each of the portions into patties – about 1/2″ thick (do not make them too thin).
  6. Place 1 heaping Tbsp. of blue cheese in the center of 6 patties.
  7. Top each with one of the remaining 6 patties and pinch the edges to seal.
  8. Refrigerate the patties for 1/2 hour.
  9. Grill the burgers until they are cooked to your liking.
  10. Serve burgers on toasted buns with avocado, tomato, arugula or lettuce, and your other favorite burger condiments.

    PERFECT does not begin to describe this burger!!!! It is so savory, sweet, juicy, and the bursts of blue cheese are incredible! Thank you for sharing this!

    These are scrumptious with or without the bun!

  4. Beth says:

    Mary, I want you to make this the next time we come for a visit…even if you have to barbecue in the December rain!

  5. I think a fine addition to the plate above would be hand cut fried wedge potatoes (aka think cut fries)……oh that looks so good.
