Whats In these Low Carb Pickled Onions?

If you’re avoiding sugar, these are perfect! We used erythritol to sweeten these but if you need to use a different sweetner, go right ahead. Monk fruit sweetner would also be a great choice.

You only need:

• Onions
• Salt
• Apple cider vinegar
• Sweetener
• Water

What do you serve these with?

These Pickled Red Onions are also a great topping for tacos and salad bowls. The tangy flavor adds a great punch but doesn’t overpower the other flavors.

I’ve added them to basically all of my carnitas recipes!

You can also serve them with this low carb Instant Pot taco meat!

How long can you store these pickled onions?

These hold for up to 5 days in the fridge. They probably won’t last that long though! That’s okay, they’re so easy to make, you’ll be able to make another batch when they run out.
