In a large Dutch oven, cook beef over medium heat until browned and crumbly; drain well. Stir in beans, tomatoes, and Worcestershire, and bring to a boil. Reduce heat, and simmer, uncovered, stirring occasionally, for 1 hour.
Preheat oven to 450°. Line a large rimmed baking sheet with foil.
Spread fries onto prepared pan. Bake for 25 minutes. Leave oven on.
Reserve 2 cups fries; spread remaining fries in bottom of a 13x9-inch baking dish. Sprinkle 2 cups cheese onto fries. Using a slotted spoon, spoon chili onto cheese. Spread reserved fries around sides of pan; sprinkle with remaining 2 cups cheese.
Bake until hot and bubbly, about 20 minutes. Let stand for 10 minutes before serving. Garnish with onion and jalapeño, if desired.
