Updated July 30, 20261 min readCited sources

Pepperoncini are mild chili peppers from the species Capsicum annuum. They are commonly eaten fresh or pickled, and are a staple in Italian and Greek cuisine.

Botany

Pepperoncini are small, thin-walled chili peppers in the nightshade family, grown as annual plants in warm conditions. They are typically harvested when light green or yellow-green, though they can turn red as they fully ripen.

Culinary use

These peppers are best known for pickling, but are also eaten fresh, added to salads, and used on sandwiches and antipasto platters. Their mild heat (100–1,000 Scoville Heat Units) makes them suitable for adding flavour without strong spiciness.

Origin and distribution

Pepperoncini are associated with southern Europe, especially Italy and Greece, where they are also called friggitello, golden Greek pepper, or Tuscan pepper. They are widely grown in the United States and commonly found pickled in Canadian grocery stores.
