Description

Zesty Mexican Pickled Red Onions bring tangy, colorful magic to your plate with minimal effort. Crisp, jewel-toned slices deliver bold flavor that elevates sandwiches, tacos, and salads while making you look like a culinary genius.


Ingredients

Scale

Produce:

  • 2 medium red onions
  • 1 clove garlic

Pickling Liquid:

  • 1/2 cup apple cider vinegar
  • 1/2 cup water
  • 2 tbsp granulated sugar
  • 1 tsp salt

Seasonings and Optional Spices:

  • 1/2 tsp black peppercorns
  • 1 bay leaf
  • 1 pinch red pepper flakes (optional)

Instructions

  1. Peel and slice red onions into thin, uniform half-moons, ensuring even cuts for consistent pickling and texture.
  2. Crush garlic clove lightly to release aromatic oils without completely breaking it apart.
  3. In a clean glass jar, layer sliced onions and gently nestle crushed garlic between onion layers.
  4. Combine apple cider vinegar, water, sugar, and salt in a saucepan, whisking until sugar and salt completely dissolve.
  5. Add black peppercorns, bay leaf, and red pepper flakes to the pickling liquid for enhanced flavor complexity.
  6. Bring liquid mixture to a gentle simmer over medium heat for 2-3 minutes, stirring occasionally to prevent scorching.
  7. Carefully pour hot pickling liquid over onions in the jar, ensuring all onion slices are completely submerged.
  8. Allow mixture to cool at room temperature for 15-20 minutes, which helps onions soften and absorb flavors.
  9. Seal jar with a tight-fitting lid and refrigerate for at least 1 hour before serving, though flavor develops best after 24 hours.
  10. Pickled onions will remain fresh and crisp in refrigerator for up to 2 weeks when stored properly.

Notes

  • Select firm, bright red onions with smooth skin for the best pickling results and vibrant color.
  • Use apple cider vinegar for a slightly sweet, mellow tang that complements the onions’ natural sharpness.
  • Experiment with different spice combinations like whole cloves, mustard seeds, or fresh thyme sprigs to customize flavor profile.
  • Adjust sugar levels for a more tangy or sweeter pickle depending on personal preference or intended dish pairing.
