Flat Top Porcini-Dusted Smashed Burger
By Timothy Hollingsworth
We’re taking the classic smashed burger up a notch with porcini powder and a special sauce. The dried mushroom powder, sometimes called dust, gives the meat an even deeper savory flavor. If your supermarket carries dried porcinis but not powder, simply grind the whole dried mushrooms in a spice grinder. Spreading a little mayo on the buns before toasting them makes them nicely browned and crisped.

1
For the seasoning: In a small bowl, mix the salt, pepper, and porcini powder.
2
For the sauce: In another small bowl, combine the ¼ cup mayonnaise, ketchup, cornichons, diced white onion, onion powder, and granulated garlic and stir to combine. (Cover and refrigerate if not using right away.)
3
Spread a little mayonnaise on the cut sides of the buns and reserve. Prepare the patties by dividing the beef into 8 equal portions (about 4 oz each) and rolling each portion into a ball. Place the balls on a rimmed baking sheet and sprinkle the tops with about half of the porcini seasoning. (You’ll use the rest during cooking.)
4
Have handy a large, metal spatula and a 5- to 6-inch inch square of parchment paper (to keep the patties from sticking to the spatula). Preheat 2 adjacent zones on the flat top to medium-high heat and 1 zone to medium-low heat, for 8 to 10 minutes.
5
Squeeze or drizzle the oil onto the hot cooktop and use the spatula to spread it evenly. Place the buns cut side down on the medium-low zone and toast until golden, about 1 minute. Transfer the rolls to a plate or platter.
6
Place a beef ball on the medium-high hot surface. (If adding white onion, place some on top of the ball.) Top the ball with the parchment square, then press down firmly with the spatula to create a thin patty 5 to 6 inches across. Repeat to make the other 7 patties. Cook each patty until nicely browned on one side, about 3 minutes.
7
Carefully flip the patties, sprinkle with the remaining seasoning, and top with the cheese. Cook, covering the patties with the dome to speed the melting, if desired, until the cheese is melted, about 1 minute more. Transfer the patties to a clean plate, stacking them to make 4 double patties.
8
To serve, place a stack of two patties on the bottom bun. Top with some of the red onion and a couple slices of tomato. Spread some special sauce on the top bun, top the burger with it, and take a big bite. Enjoy!
