Add the olive oil in a large cast iron pan over high heat. Once the oil shimmers, add the Padrón peppers and let them sauté until they are blistered on both sides, about 5-7 minutes.
Remove from the oil and season with salt and lemon juice. Serve immediately.
Notes
These bite sized peppers are pretty mild in taste, with about 1 in 10 being hot, similar to Shishito peppers.
