Cook the Beef:
In a large soup pot or Dutch oven over medium heat, brown the ground beef. Drain excess fat if needed.
Sauté Aromatics:
Add diced onion and bell peppers. Cook for 5–6 minutes until softened. Stir in garlic and cook another minute.
Add Tomatoes & Broth:
Stir in diced tomatoes, tomato sauce, tomato paste, Italian seasoning, smoked paprika, salt, and pepper. Pour in the beef broth and bring to a simmer.
Simmer the Soup:
Reduce heat and simmer uncovered for 20–25 minutes, stirring occasionally, until flavors meld and veggies are tender.
Add Rice & Finish:
Stir in the cooked rice and heat through for 5 more minutes. Taste and adjust seasoning as needed.
Serve:
Ladle soup into bowls and top with shredded cheese or fresh herbs, if desired.
