I had a friend visiting and I took her to my favorite spice shop, Savory Spice, to restock her spice pantry. One of the items she wanted was Oregano. I asked her if she wanted Mediterranean Oregano or Mexican Oregano. She looked at me strangely and asked about the difference. She said she did not know there was more than one kind. Since she is a great cook, I figured if she didn’t know this that maybe many of you did not know either. Thus, this Cooking Tip was born.

What most cooks think of as oregano is probably the Mediterranean version. It is part of the mint family, Lamiaceae.
Mediterranean is a bit of a generic term for all types of oregano grown in that region. Different varieties include Greek, Italian and Turkish. Most supermarket versions will not specify what type it is but good spice shops will often list that information. The most common is probably Greek. It is typically known as the “true oregano” although some will also apply that term to the Italian variety.
Mediterranean oregano in general has a robust flavor with sweet, minty and peppery notes. It will, however, vary somewhat in taste depending on which variety it is. Some may be more bitter, sweet or peppery than others. Greek is said to be the most savory and earthy, Turkish is the most pungent and the Italian is the mildest. The latter is actually a hybrid of sweet marjoram (also a type of oregano) and common oregano.
Mexican oregano is native to Mexico, the southwestern United States and Central America. It is part of the Verbenaceae family, to which lemon verbena also belongs. Its flavor is different than Mediterranean oregano. It has pungent, citrusy flavors with a peppery note and a subtle licorice undertone.
When do you use which variety? Well, if you have read many of these Cooking Tips, you will know I do not have many hard and fast rules. However, the best results happen when you pair the particular variety to the cuisine of that geography.
Therefore, you would use the Mediterranean variety when you are making those dishes. It pairs well with flavors such as onion, garlic, basil, flat-leaf parsley and thyme. It is especially known for its use in Italian dishes including pizza & pasta sauce, herb butters and Italian vinaigrettes.
Pair your Mexican oregano with other spices such as cumin, chili and paprika. Use in dishes with Mexican or southwest-type flavors such as chili, enchiladas or salsa.
One last tidbit about oregano. Chefs generally prefer fresh herbs over dried herbs in many preparations. However, oregano maintains excellent flavor when dried. In fact, many feel that fresh oregano is too pungent and they prefer the dried.
Did you know that there were different types of oregano? Do you always use just one or do you switch it up depending on what you are cooking? Now that you know the differences, I hope you will feel much more comfortable using this wonderful herb!
