01 - In a large soup pot or Dutch oven over medium heat, cook the ground beef, breaking it apart with a spoon, until fully browned. Drain excess fat if needed.
02 - Add onion, garlic, carrots, and celery to the pot. Sauté for 5 minutes, stirring occasionally, until vegetables begin to soften and onion becomes translucent.
03 - Stir in diced potatoes, beef broth, diced tomatoes with their juices, bay leaf, dried thyme, smoked paprika, salt, and black pepper. Mix well to combine all ingredients.
04 - Bring the mixture to a boil over high heat, then reduce heat to low. Cover and simmer for 25 minutes, stirring occasionally, until potatoes and vegetables are fork-tender.
05 - Stir in frozen peas and continue cooking for 5 minutes until heated through. Remove and discard the bay leaf. Taste the soup and adjust salt and pepper as needed.
06 - Ladle hot soup into bowls. Garnish with chopped fresh parsley and shredded cheddar cheese if desired. Serve immediately with crusty bread.
