Roasted Balsamic Vinegar Red Onions and Blue Cheese Burger

From the kitchen of: Isabel  Makes: 4 burgers
Total time: 10 min to prep, 30 min to cook

The combination of blue cheese and balsamic vinegar packs a huge punch in this burger. Literally. I took a bite of it and the flavors were unbelievable strong, but so amazingly delicious. I love blue cheese. It has a very pungent taste. The blue/green veining in this cheese may not look too appetizing, but don’t let that scare you. The cheese is texturally creamy, it has a sharp and tangy bite. Blue cheese has an acquired taste, so if it’s not your favorite, there are hundreds of other cheeses to choose from. The red onions roasted in balsamic vinegar adds another dimension to the burger. The slight crunch from the onions gives it more texture. The roasted balsamic vinegar adds some sweetness and tartness, which help cut the sharpness of the cheese. Everything about this burger is bold and flavorful. So, if you love blue cheese and balsamic vinegar, this combination is for you.

1 large red onion, sliced
1/8 cup balsamic vinegar, plus a few more dashes
1 pound ground sirloin
1 tablespoon worcestershire sauce
1/2 teaspoon onion powder
1/2 teaspoon garlic power
blue cheese
olive oil
salt + pepper

1. Roast red onions.
Preheat oven to 350º. Meanwhile, slice the red onion about 1/4-inch thick. Place the onions on a baking sheet and season with 1/8 cup of balsamic vinegar, 1/8 cup olive oil, salt and pepper. Mix to combine and roast in the oven for 30 minutes, turning occasionally. Once the onions are roasted, remove from oven and add a few more dashes of balsamic vinegar. Mix together.

2. Grill the burgers. While the onions are roasting, heat a grill pan at medium temperature. Place the ground sirloin on a cutting board. Season with worcestershire sauce, onion powder, garlic powder, salt and pepper. Mix together and then divide the seasoned beef into four equal parts. Flatten each portion to desired thickness. Place the patties on the hot grill pan and cook for 3-4 minutes each side.

3. Assemble burger. While the burger is cooking, slice the blue cheese into relatively-thick slices. It will crumble, but no worries. It’s good either way. On a toasted hamburger bun, place the burger and top with sliced (or crumbled) blue cheese and balsamic vinegar roasted onions. Add a touch of mayo and enjoy!

  • What kind of grill pan do you have? I’m in the market because my ikea pan is wearing thin!

  • That looks so tasty, at 2am I could cry… I saw those delightful looking burgers on Richmond.com and thought you had a restaurant. I was so sad you didn’t.

    I can’t cook, so will you be making these anywhere ever? Glad to buy one. Like the pictures too, very nice depth of field. Yummy!
