Make these sweet pickled red onions with only 4 ingredients and water! Add to tacos, eggs, even salads! For best pickled flavor allow these to marinate in the fridge for at least a day.


1 large red onion or 2 medium red onions
1 cup warm water
1 tablespoon + 1 teaspoon white sugar
1/2 cup white vinegar
1 and 1/2 teaspoons salt


1. Slice the onion into thin slices and add to a large mason jar.

2. In a separate jar, combine the warm water and sugar. Then add the salt and vinegar. Stir to dissolve, then pour into the jar with the onions. Cover and store in the fridge for 24 hours.

You can eat these after about an hour, but allowing them to pickle for about a day will produce a softer onion and a stronger pickled flavor.
