Gourmet Blue Cheese Burgers with Pancetta (Print version)

Juicy beef burgers topped with crisp pancetta, blue cheese sauce, arugula, and toasted brioche buns.

# Ingredients:

For the blue cheese sauce

01 - 3 oz (85 g) blue cheese, crumbled
02 - 1/4 cup (60 g) mayonnaise
03 - 2 tablespoons (30 g) sour cream
04 - 1 tablespoon chopped fresh chives
05 - 1 teaspoon fresh lemon juice
06 - 1/4 teaspoon black pepper

For the burgers

07 - 1 1/2 lb (680 g) 80/20 ground beef
08 - 1 teaspoon kosher salt
09 - 1/2 teaspoon black pepper
10 - 4 oz (115 g) thin sliced pancetta
11 - 4 brioche burger buns, split
12 - 1 cup (25 g) baby arugula
13 - 1/4 small red onion, very thinly sliced

# Instructions:

01 - Mash the blue cheese, mayonnaise, sour cream, chives, lemon juice, and black pepper in a small bowl until creamy with a few small cheese pieces left. Refrigerate while you cook.
02 - Divide the beef into 4 portions and gently shape into patties about 3/4 inch thick. Press a shallow dimple in the center of each patty and season both sides with salt and pepper.
03 - Cook the pancetta in a skillet over medium heat for 3-5 minutes, turning once, until crisp. Transfer to paper towels. If using the skillet for the burgers, leave a thin film of fat in the pan.
04 - Heat a grill or heavy skillet over medium-high heat. Cook the patties for 4-5 minutes per side, or until the center reaches 160°F for fully cooked ground beef.
05 - Place the buns cut side down on the grill or in the skillet for 30-60 seconds until warm and lightly golden.
06 - Spread blue cheese sauce on the bottom buns. Add arugula, a burger patty, crisp pancetta, red onion, and another spoonful of sauce. Close the buns and serve right away.

# Good to know:

01 - Best served immediately after assembly.
02 - Chill shaped patties for 15 minutes if the kitchen is warm.
03 - Use an instant-read thermometer for the most reliable doneness.
