My goodness, these blue cheese burgers with caramelized onions were good. Not sorta good, but close-your-eyes-when-you-take-a-bite good. Blue cheese and onions are the perfect match. Put them on perfectly cooked burgers and you’ve got a real winner. You can make the burgers really any way you like, but for me my go-to method is on a outdoor griddle. I like my patties thin, with a bit of a crunchy edge to them, so I end up smashing them before they really get cooking.
Sometimes blue cheese makes Anita go ‘ewww’. Not the case with these blue cheese burgers with caramelized onions. The blue cheese is by no means overpowering. You do taste it, but it adds such a wonderful creaminess, a little tang, that you just want more. Make these and you’ll never want a burger any other way.

Blue Cheese Burgers with Caramelized Onions
- 3 tablespoons olive oil
- 2 medium sweet onions halved, sliced thin
- 1 teaspoon dried rosemary crushed
- 1 teaspoon kosher salt divided
- 1 1/2 pounds ground beef
- 1/2 teaspoon freshly ground black pepper
- 1/2 cup blue cheese crumbled
- 4 hamburger buns
- 8 lettuce leaves I used iceberg
- 4 slices tomato
- Note; You can make this recipe on a grill using a griddle or indoors, using a skillet (preferably cast iron).
- Heat the oil on a grill griddle or in a large skillet over medium-high heat.
- Toss the onions with the rosemary and 1/4 teaspoon of salt. Transfer to the griddle or skillet and cook 8 minutes or until starting to soften. Turn and cook another 8 minutes or until the onions are completely soft and caramelized. Add more oil as the onion cooks if they are too dry but do not drench them. Remove to a bowl, cover and keep warm until ready to use.
- Shape the beef into 4 equally-sized patties. Season well on both sides with remaining salt and all of the pepper.
- Transfer the patties to the grill or skillet and cook 5-6 minutes per side until done as desired. I prefer thin patties, so I smash my patties onto my griddle as they start to cook. Just before removing the patties, top each with some of the caramelized onion and the blue cheese crumbles.
- Toast or grilled the buns as desired.
- Top the buns with the patties. Add lettuce and tomato and serve.
