What is Pepperoncini? Discover the Flavorful World of This Tangy Chili Pepper

Pepperoncini, a variety of the Capsicum annuum species, are a culinary delight cherished for their mild heat and tangy flavor. According to the Chile Pepper Institute at New Mexico State University, these yellow-green chili peppers register between 100 to 500 Scoville Heat Units, making them a gentler option for those who prefer a milder spice. Often found pickled in jars, pepperoncini have become a staple in Mediterranean cuisine and are closely related to bell peppers and spicier chili varieties. The U.S. Department of Agriculture notes that pepperoncini are rich in vitamin C, providing nutritional value alongside their zesty taste. Whether tossed in salads, garnishing pizzas, or enhancing sandwiches, understanding what pepperoncini is can elevate your dishes with both flavor and health benefits.

The Italian word “pepperoncini” is the plural form of “pepperoncino.” In Italy, it actually refers to the hotter varieties of chili peppers generically known as “pepperone.” "Friggitelli" is the Italian word for the milder variety sold in the United States as pepperoncini. In the US, they may also be labeled as sweet Italian peppers or Tuscan peppers. They are also common in Greek and Eastern European cuisines, where they are called fefferoni, or golden Greek peppers.

Banana peppers and pepperoncini peppers are often mistaken for one another because of their similarities. As stated earlier, sometimes banana peppers are sold as pepperoncini peppers! This is because banana peppers and pepperoncini are very similar in many ways, especially when they’re pickled. But there are some differences between the two peppers.

The biggest difference is that while banana peppers have no heat, pepperoncini's have a small amount of heat in their mildest variety. The shape and skin texture of each pepper can differ ever so slightly as well. But the main difference between the two peppers is their heat factor.

The pepperoncini plant is a bushy, annual variety that grows to a height of about 3 feet (1m). The peppers it produces are tapered, wrinkled along their length and lobed at the ends. They are usually harvested at 2- or 3-inches long (5 to 8 cm), while they are still sweet and yellow-green. When allowed to mature, the peppers turn bright red and grow stronger in flavor.

If you decide to grow your own pepperoncini pepper plant, you will need to know when to harvest the peppers. Pepperoncini peppers take roughly seventy-two days to reach maturity. Once the plant begins to grow peppers, you will want to pick the peppers when they are a pale green or yellow color. As the plant continues to mature, the peppers will eventually develop pinkish skin. Then the color will deepen into red, which is a sign that the peppers have already lost their flavor. Once the peppers are fully mature, they will have red and wrinkly flesh, so it’s important to pick pepperoncini peppers when they have their signature yellow-green appearance.

The heat of chili peppers is caused by a component called capsaicin. The amount of capsaicin in various types of chili peppers is measured according to the Scoville scale, named for American chemist Wilbur Scoville. The scale ranges from zero units for the bell peppers, which have no capsaicin, to 16,000,000 units for pure capsaicin. Pepperoncini rank in the second-lowest category, 100 to 500 Scoville units.

In Italy, pepperoncini may be eaten fresh, they may be packed in olive oil or they may be dried. They are an essential component of the Italian dish known as antipasti, which is a mixed platter of pickles, olives and cured meats such as prosciutto and salami. Pepperoncini are widely used in cooking, especially in tomato sauces for pasta and in olive oil dipping sauces for crusty Italian bread.

Pepperoncini are popular in delicatessens as a filling for sandwiches or as an ingredient for pasta salads. Pepperoncini are an essential component of Greek salads, in which they are tossed with spinach, tomatoes, olives and feta cheese. They may also be featured on restaurant salad bars. For home use, pepperoncini are available in most supermarkets, where they are sold either whole or sliced. Some people enjoy pickled pepperoncini instead of fresh peppers on salads or in sandwiches.

To pickle pepperoncini peppers, you’ll need a few things. You will need pepperoncini peppers, garlic cloves, black peppercorns, vinegar, water, pickling salt, sugar, jars with lids, a hot water bath, and canning tools like a ladle and jar filler. First, wash and cut your peppers into pieces. Then add the water, vinegar, salt, and sugar to a large pot. Bring the pot to a boil, then lower the heat to keep the water hot but not boiling.

Add the cut peppers to your jars, as well as the peppercorns and garlic. Ladle the liquid from the large pot into the jars, but leave some space at the top of the jar. Close the jars with the lids and rings and place them in the canner. Process the jars for ten minutes, then allow the jars to rest for five minutes in the canner. Place the jars in a dark space to cool down for twelve to twenty-four hours. Lastly, after the twenty-four hour mark, check the seals on your jars. Pickled pepperoncini are good to have around your home because they make a healthy addition to sandwiches and salads.
