Ingredients

  1. 1 cup very thinly sliced sweet onion (8 oz.)
  2. 1 ½ cups buttermilk
  3. 5 cups Vegetable oil, for frying
  4. ¾ cup flour
  5. 1 teaspoon salt, divided
  6. ½ teaspoon black pepper
  7. ¼ teaspoon cayenne pepper
  8. ¼ teaspoon paprika
  9. ½ teaspoon smoked paprika
  10. ¼ teaspoon celery salt
  11. ¼ teaspoon chili powder
  12. ¼ teaspoon garlic powder
  13. ¼ teaspoon onion powder
  14. 1 ½ pounds ground chuck or 80% lean ground beef
  15. 1 tablespoon canola oil
  16. ¼ cup bottled whiskey-flavored barbecue sauce, plus more for serving
  17. 4 slices Cheddar cheese
  18. 4 sesame seed hamburger buns
  19. ½ cup mayonnaise
  20. 8 thin tomato slices
  21. 1 cup shredded iceberg lettuce

Instructions

  1. Combine onions and buttermilk in a bowl and soak at room temperature for 1 hour.
  2. Pour oil to a depth of 1 1/2 inches into a deep, heavy-bottomed skillet or pot or a deep-fat fryer; heat to 350 degrees F (175 degrees C).
  3. Meanwhile whisk together flour, 1/4 teaspoon salt, black pepper, cayenne, and 1/4 teaspoon paprika in a large bowl for the breading. Remove onions from buttermilk, allowing excess to drip off. Toss onions in the breading until well coated.
  4. Set a wire rack on a rimmed baking sheet. Working in 3 batches, fry onions, turning occasionally to break up any clumps, until crisp and golden, 1 to 2 minutes. Transfer to wire rack to drain. Repeat with remaining onions.
  5. For rub, stir together 1/2 teaspoon smoked paprika, celery salt, chili powder, garlic powder, onion powder, and remaining 1/2 teaspoon salt in a small bowl. Shape beef into 4 patties, about 4 inches in diameter. Brush patties with oil; sprinkle both sides with rub.
  6. Preheat grill to medium-high and lightly oil grate. Grill patties, uncovered, about 5 minutes or until slightly charred.
  7. Flip patties; brush barbecue sauce evenly over patties. Continue cooking about 3 minutes more or until charred and a thermometer inserted into centers registers 160 degrees F (70 degrees C). Top patties with cheese; grill, covered, until cheese is melted, about 1 minute more. Grill buns, cut sides down, uncovered, until toasted, 30 seconds to 1 minute.
  8. Spread buns with mayonnaise and additional barbecue sauce. Fill buns with patties, onion straws, tomato, and lettuce. Serve immediately.
