What are the key ingredients commonly used in Italian cuisine?

The key ingredients commonly used in Italian cuisine include olive oil, garlic, tomatoes, basil, and pasta, which are staples that reflect the traditional flavors and techniques of Italian cooking. Olive oil serves as the primary fat for cooking and dressing dishes, offering a rich flavor that enhances various recipes. Garlic adds depth and aromatic qualities to sauces and dishes. Tomatoes are fundamental in many Italian sauces, salads, and recipes, providing acidity and sweetness that balance flavors.
