In a large pot of boiling salted water, cook pasta according to package instructions; drain well and set aside.
Heat 1 tablespoon olive oil in a large stockpot or Dutch oven over medium heat. Add Italian sausage to the skillet and cook until browned, about 3-5 minutes, making sure to crumble the sausage as it cooks; drain excess fat and set aside.
Add remaining 1 tablespoon oil to the stockpot. Stir in garlic, onion, carrots and celery. Cook, stirring occasionally, until tender, about 3-4 minutes.
Whisk in chicken broth, tomato sauce, diced tomatoes, basil, oregano, thyme, Italian sausage and 1 cup water; season with salt and pepper, to taste. Bring to a boil; reduce heat and simmer, covered, until vegetables are tender, about 10-15 minutes.
Stir in pasta and beans until heated through.
