Ingredients
- 1 pound frozen crinkle-cut french fries
- 1 pound ground beef
- Kosher salt
- Freshly black pepper
- 1/2 medium white onion, grated on the large holes of a box grater (about 1/3 cup)
- 4 slices American or cheddar cheese
- 4 hamburger buns, split
- Sliced pickles, for serving
Directions
- Arrange 2 racks to divide the oven into thirds and heat to 425°F.
-
Line a large rimmed baking sheet with aluminum foil and place on the upper rack. Place the french fries in an even layer on a second unlined baking sheet, then place on the lower rack. Bake for 25 minutes. Meanwhile, prep the burger patties.
-
Divide the beef into 4 equal portions. Working quickly and being careful not to overwork the meat, gently form each portion into a 1/2-inch-thick patty about 4 inches wide (or slightly wider than the diameter of your hamburger buns). Season generously on both sides with salt and pepper; set aside.
-
Place the onions on a triple layer of paper towels, roll the the onions up in the towels, and squeeze the excess onion liquid out. Sprinkle the onions over the patties and use your hands to press them gently in.
-
Carefully remove the empty, foil-lined baking sheet from the oven. Place the patties onion-side down on it. Return it to the upper rack and bake until the patties are at the desired doneness and the fries are crisp, 10 minutes for medium-rare burgers, 12 minutes for medium.
-
Remove both trays from the oven. Top each patty with a slice of cheese and place on the lower rack. Place the hamburger buns on the upper rack. Bake until the cheese is melted and the buns are warm, about 1 minute. Place the burger patties on the bottom buns and top with pickles. Season the fries with salt and serve with the burgers.
