Caramelized Onions and Blue Cheese Burgers

Caramelized Onions and Blue Cheese Burgers

From: Burgers by Sally Sampson

Comments and Substitutions: These were pretty tasty burgers. The caramelized onions take a while but they are well worth it. We used sweet onions, but I am sure Spanish onions would also be great. John's burger used gluten-free bread for the bun. The blue cheese inside the burger patty makes a huge difference. It was awesome. We have a hard time finding ground chuck, so we used just regular ground beef. We usually buy 1 1/2 lbs and make 4 burgers with it.

Recipe:

Caramelized Onions:

2 tbsp olive oil

2 large red, Spanish or sweet onions, thinly sliced

2 garlic cloves, minced or thinly sliced

1 tbsp fresh rosemary

1.2 tsp kosher salt, or more to taste

Burgers:

1 1/2 to 1 3/4 lbs ground chuck (ground beef)

3 oz blue cheese, crumbled, plus extra for topping

1 tsp kosher salt

1/2 to 1 tsp freshly ground pepper

1. Make the caramelized onions. Place a large skillet over low heat and when it is hot, add the oil. Add the remaining ingredients and cook, stirring only occasionally, until onions are deeply browned and slightly gooey, about 40 mins. If onions dry out, add water 1 tbsp at a time. 

2. Divide beef into four equal portions - do the same with the blue cheese. Using your thumb make a shallow indent in each portion of the beef and fill it with blue cheese. Shape the burger and carefully seal the opening. Form each patty about 3/4 to 1 inch thick, tossing it back and forth between your hands. To ensure more even cooking, make a 1/2 inch indentation in the centre of the burger. Handle the patties as little as possible.

3.Prepare a grill to medium-high. Clean grate and brush with oil.

4. Sprinkle both sides of the burgers with the salt and pepper. Place the burgers on the grate and grill until well seared on both sides, about 5 mins for medium-rare and 6 mins for medium. Top with more blue cheese and let melt. Toast buns if desired. Transfer burgers to buns and serve immediately.
