Ingredients
- 2 lbs. ground chuck
- 1 lb. ground sirloin
- 3 tbsp steak sauce
- 6 extra-large egg yolks
- 1 1/2 tsp kosher salt
- 3/4 tsp black pepper
- 4 tbsp cold unsalted butter
- 8 to 10 burger buns
- 8 oz. blue cheese
- Arugula, for serving
- Sliced tomatoes, for serving
Directions
-
In a large bowl, carefully mix the meats, steak sauce, egg yolks, salt and pepper with the tines of a fork, but do not mash the mixture. Lightly form patties and press lightly into shape. Press a thin slice of butter into the top of each burger, making sure the meat entirely encases the butter.
-
Prepare a grill and cook the burgers for 4 minutes on one side, turn, and cook for 3 minutes on the other side for medium-rare. Remove to a plate and cover with foil. Allow the burgers to rest for 5 minutes. Grill the buns, cut side down, for 1 minute, until toasted. Place the burger and a slice of blue cheese on each buns, plus arugula and tomato and serve hot.
