This sweet pickled red onion recipe takes only 5 minutes to make. Sweet pickled onions are a delicious salad topping or an easy addition to sandwiches, burgers, hot dogs, or tacos.
Spring and summer are fast approaching and that means changes to our weekly menu. Warm weather foods in my house include lots of salads, sandwiches, and burgers on the grill. I love red onions on my salads and came across a delicious kale salad recipe that called for picked red onions. Pickling red onions is so incredibly easy so I thought I would whip up a batch and keep them in the fridge as an easy salad topping this spring!
Tips for Making Pickled Red Onions
This pickled red onion recipe is seriously so easy it really doesn't need much more info but here are a few tips to get you started:
- You will need to peel the onion first. Then, slice it into thin slices. If you want them really thin, use a Mandoline Food Slicer.If you don’t have a mandoline or want a slightly thicker slice, a sharp knife will work fine, too. Just watch your fingers!
- Place the slices into a pint sized mason jar with a sealable lid. You won't actually be canning these but use glass anyhow. Metal and plastic are not good for storing acidic foods like pickled onions.
- In a small saucepan stir together vinegar, sugar, and salt. You can add slivers of garlic or springs of rosemary for additional flavor.
- Pour the vinegar mixture over the onions in the jar until it is full.
- Place the lid on to seal and refrigerate. You can store this in the refrigerator for about a month.
Best Vinegar for Making Homemade Pickled Onions
Vinegar is the key ingredient in this sweet pickled red onion recipe. Of course, there dozens of kinds of vinegar, so which one should you choose? Apple cider vinegar has a subtle sweetness to it that blends well with this recipe. White wine vinegar or other light tasting vinegar is also a good choice for pickling onions. Plain old white vinegar will work in a pinch but balsamic vinegar is really too strong. The balsamic flavor will completely overshadow the flavor of the red onion.
