Mexican Pickled Onions Recipe

Mexican Pickled Onions are thinly sliced red onions quickly blanched in boiling water then soaked in a mixture of fresh lime juice, apple cider vinegar, and salt. Optional spices such as garlic, jalapeño, cumin seeds, and red pepper flakes add layers of flavor. The onions develop a bright, tangy, and slightly sweet taste, adding an acidic crunch to tacos, salads, and bowls.

Description

This recipe involves slicing red onions very thinly and pouring boiling water over them briefly to soften their bite while maintaining some crispness. They are then transferred to a jar and combined with fresh lime juice, apple cider vinegar, and kosher salt, which pickles and preserves the onions with a fresh, citrusy acidity.

Optional additions like thinly sliced garlic, jalapeño slices (seeds removed if less heat desired), whole cumin seeds, black peppercorns, honey or sugar, bay leaf, oregano, allspice berries, and red pepper flakes can be added to customize flavor. After mixing and sealing the jar, the onions chill in the fridge for at least two hours to develop their tangy pickled profile.

Mexican Pickled Onions brighten dishes by adding a crisp, acidic contrast. They pair well as a garnish on tacos, salads, and grain bowls, cutting through rich or spicy foods with their sharp bite.

Best stored in airtight jars in the refrigerator, they keep for up to two weeks. The volume reduces as onions soften and absorb the pickling liquids.

Notes

  • Use freshly squeezed lime juice for the best flavor; store-bought juice can be a substitute in a pinch.
  • Store leftovers in an airtight container in the refrigerator for up to 2 weeks.
  • Volume of onions will reduce as they sit in the pickling liquid due to their softening.
  • Use jars with large mouths and tight-fitting lids like Weck jars or pint-sized Mason jars for easy packing and storage.
