Notes
How to Clean Fresh Nopales – If using fresh nopales, wear gloves or use tongs to handle them. Use a sharp knife to carefully scrape off the spines on both sides. Rinse thoroughly under cold water before chopping them into bite-sized pieces.
Use Jarred Nopales for Convenience – If you don’t have access to fresh nopales, jarred nopales are a great alternative and cut down on prep time.
Be Patient with Nopales – Some people boil nopales first to remove their natural slime (baba), but this recipe eliminates that step. Instead, sauté them thoroughly and allow any gelatinous liquid to cook off before adding eggs.
Store leftover nopales con huevo in an airtight container in the fridge for up to 3 days. Reheat in a skillet over low heat until warmed through.
