Heat a cast iron or large skillet on medium-high heat.
In the meantime, prepare shishito peppers by piercing a few holes in the peppers using a fork, knife, or toothpick. This will allow the steam to release and avoid popping while cooking.
Add shishito peppers to the dry pan, working in batches if needed to avoid overcrowding. Allow the peppers to cook for about a minute to char before flipping them. Continue to cook and flip the peppers until they’ve been evenly charred.
Transfer the peppers to a bowl, drizzle on the olive oil, and season with salt. Optional: You can add another layer of flavor by adding either freshly squeezed lemon, furikake, togarashi, or smoked paprika. Serve and enjoy!
Notes
Cast Iron / Skillet: Using a cast iron is ideal since it holds heat well and tends to be easier to create a char, however, a large pan will work as well.
Shishito Peppers: Make sure the peppers are dried very well before adding them to the pan, otherwise, they'll end up steaming instead of charring while cooking.
