Preheat the oven to 425°F. Place the cabbage on its side on a cutting board. Using a sharp knife, cut 1 inch off the top of the cabbage (reserve for another use). Slice the remaining cabbage into 4 (1/2-inch-thick) steaks and discard the root end.
02 -
Arrange the cabbage steaks on a baking sheet. Brush both sides with neutral oil and season with 1 1/2 teaspoons of kosher salt and freshly ground black pepper.
03 -
Roast the cabbage steaks in the oven until tender, about 20 to 25 minutes.
04 -
Five minutes before the cabbage is finished cooking, form the ground beef into 4 large flat patties with a diameter of about 4 inches. Season both sides with the remaining 1 teaspoon of kosher salt and freshly ground black pepper.
05 -
Place one patty on top of each roasted cabbage steak. Return to the oven and bake until the burgers reach the desired doneness, about 8 minutes for medium-rare.
06 -
Top each patty with a slice of American cheese and bake for about 1 minute, just until the cheese melts.

Serve the roasted cabbage burgers with ketchup, mustard, cooked crumbled bacon, dill pickle chips, and finely chopped red onions, as desired.
