Blue Cheese Burgers with Whiskey Glazed Onions are meaty, creamy, a little sweet, a little savory and super crave-worthy. The burger recipe comes together in just over 30-minutes and makes a great addition to your Memorial Day or 4th of July spread.



For burgers: 

2 tsp kosher salt

1 ½ tsp paprika

1 ½ tsp onion powder

1 ½ tsp garlic powder

Freshly ground black pepper

2 lbs 85% ground beef

1 tbsp vegetable oil

For onions:

2 tbsp olive oil

2 tbsp butter

3 large onions, thinly sliced

Kosher salt

1 ½ tbsp brown sugar

3 tbsp whiskey

For Garlic Aioli: 

2 tsp olive oil

½ cup mayonnaise

1 tbsp fresh lemon juice

1 tsp Worcestershire sauce

2 tsp fresh minced garlic


Brioche Bun, toasted


Blue cheese crumbles


  1. Make burgers: In a small bowl mix together kosher salt, paprika, onion powder, garlic powder and a few turns of cracked black pepper. Add ground beef to a large bowl and 2-3 tsp of the seasoning mixture. Mix together until it is incorporated but be careful not to over mix or it may result in a tough burger. Divide evenly into (6) 1-inch-thick burger patties. Indent the center of each one with your thumb. Sprinkle the remaining seasoning on top of the burger patties evenly on each side.
  2. Caramelize onions: In a medium saute pan melt oil and butter on medium-low heat. Add the onions and a sprinkle of kosher salt. Stir together and caramelize onions until medium to deep golden brown, about 20 minutes, stirring occasionally. Stir in brown sugar and whiskey and light with a long-handled lighter or skewer to burn off the alcohol. Cook for another 2-3 minutes, stirring together until most of the liquid has evaporated. 
  3. Make aioli: In a small bowl whisk together olive oil, mayonnaise, lemon juice, Worcestershire sauce, and garlic until combined. 
  4. Cook burgers: Heat a large cast-iron skillet on medium-high heat. Add the vegetable oil. Cook patties for 3-4 minutes on each side for a medium center and an internal temperature of 160-165 degrees F. Allow burgers to rest for 2 minutes or so.
  5. Assemble burgers: Spread 1 tbsp of garlic aioli between the two buns, a handful of arugula, a burger patty, 1-2 tbsp of whiskey onions and top with crumbled blue cheese.


Grilling Option: Brush burgers with a light layer of vegetable oil. Heat grill to medium-high heat, about 375-400 degrees F. Cook each side, covered, for 3-4 minutes for a medium-medium rare burger.
