1 onion, sliced into thin rings½ cup white vinegar ½ cup all-purpose flour Salt and pepper ¼ teaspoon cream of tartar 2 pounds 85 percent lean ground beef 3 garlic cloves, minced2 teaspoons plus 2 cups vegetable oil 4 slices deli American cheese (4 ounces)4 hamburger buns, toasted and buttered

Before You Begin

If food safety is your primary concern, you may want to cook your burger to a higher internal temperature. To learn more, check out this guide.

Instructions

  1. Adjust oven rack to middle position and heat oven to 300 degrees. Separate onion rings and combine with vinegar in bowl. Combine flour, ½ teaspoon salt, ¼ teaspoon pepper, and cream of tartar in large bowl.
  2. Gently knead beef, garlic, ¾ teaspoon salt, and ½ teaspoon pepper together in bowl until well combined. Shape beef mixture into four ¾-­inch-thick patties and press shallow divot in center of each. Heat 2 teaspoons oil in 12-inch nonstick skillet over high heat until just smoking. Transfer burgers to skillet and cook without moving them for 2 minutes. Flip burgers and cook for 2 minutes on second side. Transfer to rimmed baking sheet, place 1 slice of cheese on each burger, and bake until burgers register 125 degrees (for medium-rare), about 5 minutes.
  3. Meanwhile, wipe skillet clean and heat remaining 2 cups oil over medium-high heat to 350 degrees. Drain onion rings and toss in flour mixture until evenly coated. Fry onion rings, stirring occasionally, until golden brown and crisp, about 5 minutes. Transfer to paper towel–lined plate. Place burgers on bun bottoms, add desired condiments, and top with onion rings. Serve.
