Oregano is one of the most important seasonings in Italian and Mediterranean cuisine. Its use spans a variety of dishes, from tomato sauces and pastas to pizzas and meat dishes. Made with dried leaves of Origanum vulgare and/or Origanum virens, this seasoning is characterized by its strong aroma and slightly bitter taste. Great for adding at the start of cooking, oregano can be paired with herbs like parsley, rosemary, thyme, and sage.
