Bleu Cheeseburger Recipe

Form and season

Divide the ground beef into two equal portions. Gently form each portion into a patty about 3/4"–1" thick and slightly larger than the buns (they will shrink while cooking). Make a shallow dimple in the center of each patty with your thumb to promote even cooking. Season both sides evenly with kosher salt, freshly ground black pepper, and a light drizzle of Worcestershire sauce (about 1/2 tsp per side).

Let the patties rest at room temperature for 10–15 minutes while you prepare other components—this helps them cook more evenly.

Make the bleu cheese spread

In a small bowl, combine the crumbled bleu cheese, 1 tablespoon softened unsalted butter, 2 tablespoons mayonnaise, minced chives, and 1/4 teaspoon freshly ground black pepper. Mash together with a fork until coarsely combined but still slightly textured. Taste and adjust seasoning. Cover and refrigerate until ready to use.

Sauté onions

Heat 1 tablespoon unsalted butter in a skillet over medium heat. Add the thinly sliced red onion and a 1/2 teaspoon sugar. Cook, stirring occasionally, until the onions soften and begin to caramelize, about 8–10 minutes. Toward the end, add 1 teaspoon balsamic vinegar and cook 1 more minute to deglaze and concentrate flavor. Remove from heat and set aside.

Pan-sear or grill

Heat a heavy skillet or grill over medium-high heat. Add 1 tablespoon vegetable oil to the skillet (if using a grill, oil the grates). When the pan is very hot, add the patties. Cook without moving until a brown crust forms, about 3–4 minutes. Flip and cook another 3–4 minutes for medium (adjust time for desired doneness). In the final 1 minute of cooking, reduce heat to medium-low and divide the bleu cheese spread between the two patties, allowing it to soften and slightly melt over the patties.

Remove patties to a plate and tent loosely with foil for 2–3 minutes to rest.

Toast buns

Lightly butter the cut sides of the buns or brush with a little oil and toast in a dry skillet or on the grill, cut-side down, until golden and crisp, about 1–2 minutes.

To assemble: place lettuce leaf on bottom bun (if using), set the rested patty with melted bleu cheese on top, add a spoonful of caramelized onions, tomato slices and pickles if desired, then top with the bun crown. Serve immediately.
