In a large pot over medium-high heat, cook the ground beef until browned, about 5 minutes. Drain the fat and discard.
Add the onion, carrots, celery, garlic, oregano, basil, thyme, salt, and pepper. Cook, stirring occasionally, until the vegetables are softened, about 5 minutes.
Add the tomatoes, beef broth, kidney beans, and corn. Bring to a boil, then reduce the heat to low and simmer for 15 minutes.
