Rigatoni is a type of pasta that is characterized by its short, tube-like shape and ridged surface. It is typically about 1 to 2 inches long and has a wide diameter, making it perfect for holding onto sauces. Rigatoni is often made from durum wheat semolina, which gives it a firm texture that holds up well during cooking. This pasta is commonly used in various Italian dishes, such as baked pasta casseroles and hearty meat sauces. Its shape allows it to pair well with both chunky and smooth sauces, making it a versatile choice for many recipes. Rigatoni is often served with ingredients like tomato sauce, cheese, and vegetables.
