The quickest pickled red onions recipe! Thinly sliced red onions marinated in a delicious red wine vinegar pickling mixture. The perfect topping no matter what the dish.
Peel and slice the onion in half. Using a knife or a mandoline slicer, thinly slice each half into thin C-shaped slices. (I love using a mandoline slicer for thin, uniform slices.)
2 medium red onions
Transfer the sliced onions to a jar or container. Add the red wine vinegar, salt, pepper and cumin to the onion. (The onions won’t be fully covered in vinegar, and that’s totally okay.)
1/4 cup red wine vinegar, ¼ tsp salt, ½ tsp cumin, ¼ tsp ground black pepper
Close the lid and shake until onions are evenly coated in the vinegar and seasonings.
Let the onions pickle in the fridge for at least an hour before using. (The onions will keep in the fridge for up to 2 weeks.)
