This quick pickled red onions recipe is easy to make in just 30 minutes with just 4 main ingredients!  See notes above for extra seasonings that you are welcome to add in too.



  • 1 large red onion*, peeled and very thinly sliced
  • 3/4 cup apple cider vinegar
  • 1 teaspoon fine sea salt
  • 12 tablespoons sweetener (such as maple syrup, honey, sugar, etc.)


  1. In a small saucepan*, stir together the vinegar, salt and your desired amount of sweetener.  Cook over medium-high heat until the mixture reaches a simmer.
  2. Place the thinly-sliced onions in a small bowl or pint-sized mason jar.  Pour the hot vinegar mixture over the onions.  Stir until combined.  (Or if using a mason jar, place the lid on top and give the jar a quick shake.)  Let the onions marinate for 30 minutes.
  3. Serve immediately.  Or refrigerate in a sealed container for up to 2 weeks.

*Microwave option: Feel free to also heat the vinegar mixture in the microwave until it reaches a simmer.  Then add it to the onions, as directed.
