Heat the olive oil in a large pot over medium heat until shimmering.

Add the sliced carrot, celery, diced onion, and minced garlic. Sauté until the onion softens, about 2-3 minutes.

Pour in the beef broth, water, canned diced tomatoes, tomato paste, diced potato, and sprinkle in the Italian seasoning. Stir and bring to a boil.

Once boiling, reduce heat and let it simmer for 15 minutes.

Add the alphabet noodles and cook for an additional 7-8 minutes until noodles are al dente.

Taste the soup and add salt and pepper as needed.
