Blue Cheese Burgers with Caramelized Onions
These blue cheese burgers are juicy, flavorful, and topped with creamy blue cheese and sweet caramelized onions. A delicious twist on a classic that’s perfect for any cookout or weeknight dinner.
Ingredients
For the Onions:
- 1 tbsp Butter
- 2 Onions, sliced
- ¼ tsp Salt
For the Burgers:
- 1⅓ pound Ground beef
- 2½ tsp Worcestershire sauce
- 1 tbsp Montreal Steak Seasoning
- 3 ounces Blue Cheese
- 4 Hamburger buns, Brioche recommended
Instructions
Prepare the Caramelized Onions (Can be made ahead)
- Melt butter in a large skillet over medium heat
- Add sliced onions and cook for 5 minutes, until softened
- Sprinkle with salt and mix well
- Reduce heat to low and continue cooking for 60-80 minutes, stirring frequently, until deep golden brown. (See note below)
For the Burgers:
- Preheat grill to 400℉ (Or heat a skillet over medium-high heat)
- In a large bowl, combine ground beef, Worcestershire sauce, and steak seasoning. Mix well
- Form into 4 hamburger patties
- Place on preheated grill (or skillet) and cook over medium/ medium high heat until desired doneness is achieved. (See notes below)
- Add blue cheese to each burger patty during the last 1–2 minutes of cooking, just until melted.
Serving instructions
- Place patties on toasted buns
- Top with a generous spoonful of caramelized onions.
- Add condiments such as mayonnaise, Dijon mustard, or ketchup, if desired.
Notes
- Buns: Brioche buns work beautifully for this recipe—light, fluffy, and slightly sweet.
- Make-ahead Tip: Onions can be caramelized in advance and reheated in the microwave before serving.
- Caramelizing onions: Stovetops and types of pans vary greatly. If onions are beginning to burn, reduce the heat. If they are not turning brown, raise the heat slightly. Keep a close watch on the onions during cooking so that any adjustments may be made.
- No Grill? A skillet on the stovetop is a great alternative. (I recommend cast iron)
- Cooking Tip: Wait until juices pool on top of the patties before flipping. For juicy burgers, try to flip only once.
- Doneness: Cooking time will vary depending on how you like your burger. I prefer mine well done.
