What type of pasta is shaped like small rice grains and often used in soups?

The type of pasta shaped like small rice grains and commonly used in soups is orzo. This pasta is unique because its small, grain-like appearance allows it to blend seamlessly into broth-based dishes, adding texture without overwhelming the flavors of the soup. This makes orzo particularly versatile; it can be used in a variety of soups, salads, and even baked dishes. The other pasta types listed have distinct shapes and uses: fusilli has a spiral shape ideal for holding onto sauces, penne is tubular and suited for chunky sauces, and fettuccine is flat, typically served with creamy sauces. Orzo's unique size and shape are what make it especially suitable for soups, enhancing both presentation and mouthfeel in the dish.
