Pickled Red Onion

Enjoy a burst of flavour and colour with this delicious Mexican quick pickled red onion recipe. Simple to prepare, these crisp, tangy onions are marinated in a blend of vinegar, salt, and a hint of sweetness, transforming them into the perfect topping for a variety of dishes. Whether layered on burgers, piled onto sandwiches, sprinkled over fresh salads, or used as a pizza garnish, pickled red onions add a zesty crunch and vibrant appeal to every bite.

Beyond their irresistible taste, pickled red onions offer several health benefits. Red onions are naturally rich in antioxidants, especially quercetin, which can help support heart health and reduce inflammation. The pickling process helps retain these beneficial compounds while adding probiotics when fermented, which can contribute to gut health. Additionally, red onions are low in calories and contain important nutrients such as vitamin C, potassium, and folate. Using vinegar in the pickling liquid may also help regulate blood sugar levels and aid digestion. Incorporating these bright, flavorful onions into your meals is an easy and delicious way to boost both nutrition and taste.

Course Side Dish

Ingredients
  

  • 2 tsp dried marjoram or oregano
  • 1 bay leaf
  • 1 tsp black peppercorn
  • 1 cup water
  • 2 tbsp white vinegar
  • 2 tbsp apple cider vinegar
  • 2 cloves garlic peeled and slived in half
  • 2 red onions
  • 1 lime optional

Instructions
 

  • Add all ingredients except the onion to a pot and bring to a boil.
  • When boiling vigorously, turn off the element and add the onion.
  • Allow to completely cool before straining, remove the bay leaf
  • Add the onion mix into a jar and finish with the juice of one lime (optional).
  • Pour the strained liquid into the jar until full.
  • Seal and place in the fridge.
  • The pickle will be ready to use after one hour of sitting in the brine, and will last in the fridge for around a month
  • To get the closest, most authentic flavour of Mexican pickle, use marjoram. Mexican oregano, traditionally used, is not the same as the regular oregano. Mexican oregano has a more citrus taste where regular oregano is more sweet

Normally you might find me behind the coding of our sites but over the years I have become much more concerned about what has been happening in the kitchen as well - families do that for all of us don't they? Background experience is in Account Management and Web Development but as my passion has grown for WFPB so has my desire to speak out.
