How to Make Seasoned Olive Oil

Shares & Saves

A good way to add a distinctive flavor to home-cooked dishes is to use seasoned, or flavor-infused, oils, particularly olive oils. Although olive oil can become rancid sooner than other oils, it holds the seasonings and flavors well. By putting it in smaller bottles or jars, you can give seasoned olive oil to friends as a gift and help preserve the integrity of the oil. Infused olive oil can be used in most sauces as well as stir fries or as a drizzle.

Things You'll Need

  • Good olive oil
  • Herbs or spices of your choice, such as basil, thyme, rosemary, bay leaf, sage, a variety of peppercorns, chiles, oregano, thinly sliced garlic, lemon or lime
  • Knife
  • Boiling pot
  • Water
  • Food processor or blender
  • Strainer or funnel
  • Cheesecloth
  • Bowl
  • Clean, sterile decorative bottles or jars

Making A Selection

  • Select herbs based on the flavors you’re trying to achieve as well as those that combine well. Thyme and rosemary are a good combination, as are garlic and rosemary. Rosemary and basil also are good together. A variety of peppercorns goes well with anything. Other herbs , such as sage, work well alone. Also select a good quality olive oil. Virgin and extra virgin are most flavorful.

  • Decide whether to use fresh or dried herbs. Fresh herbs are more flavorful, while seasoned olive oils made using dried herbs have a longer shelf life.

  • Rinse the herbs gently, if using fresh herbs, taking care not to tear the leaves. Blanch enough leaves to fill about a quarter of the container for about three minutes. Strain and put into cold water for several seconds to seal in the color and flavor. If using leafy herbs, such as basil, roughly chop them. Sprigged herbs should be left whole. Pat the herbs dry.

  • Place fresh herbs, garlic, chilis, or other selections about a quarter of the way up in the sterile container and fill with olive oil. Seal. If using dried herbs, put about herbs in about ¼ of the container and then fill will with extra virgin olive oil.

  • Allowing the oil to set for one month will produce a stronger flavor. Once the oil is infused, typically 10 days to one month, remove solid fruit, chilis or garlic cloves by either straining the oil through a cheese cloth-lined strainer or funnel or by spooning them out.

Tips & Warnings

  • Storing seasoned olive oils depends on whether you made them with fresh or dried herbs. Those with dried herbs can be stored in a cool, dry place for up to a year. Those infused with fresh herbs can be stored for up to a month.
  • Drying the herbs is particularly important because although oil alone can not grow bacteria, any of the herbs containing water and mixed with oil can produce botulism, a paralytic condition that can lead to death due to respiratory failure.
