Ingredients
  

  • 1 red onion
  • Juice of 5-6 limes
  • Salt to taste, about 1 tsp to start.

Method
 

  1. Prep the Onion: Peel and thinly slice the red onion into half-moons or rings.
  2. Pickle: Place the sliced onion in a jar or bowl. Pour the lime juice over the onions and add a generous pinch of salt. Toss to combine, making sure the onions are fully coated in the juice.
  3. Marinate: Let the onions sit at room temperature for at least 5 minutes, stirring once or twice. They’ll soften and turn bright pink as they pickle. For deeper flavor, refrigerate for a few hours or overnight.
  4. Serve: Use immediately or store in the fridge for up to 1 week. These are perfect on tacos, grain bowls, sandwiches, and more.

Notes

When stored properly in a sealed glass jar or airtight container in the refrigerator, Mexican pickled onions will stay fresh for up to 2 weeks. Their flavor intensifies over time, and the color becomes deeper pink.
