Ingredients for Pickled Red Onions

1 big red onion (about 150 g)
1 Tbsp apple cider vinegar
1/4 tsp raw cane sugar

Instructions

Cut the onion into wafer-thin half rings.
Mix vinegar and sugar and pour over the onion rings.
Leave covered with a plate in the fridge until 15 minutes before use.

Notes

Use red wine vinegar instead of apple cider.
Use any sugar of your choice.

🧅 What Kind of Onions Are Best for Pickling?

For the best results, use sweet or semi-sweet onion varieties, especially red onions like Red Baron or Black Prince. These types are ideal for pickling because they have fewer essential oils than yellow onions, making them milder and more pleasant when raw or marinated.

⚠️ Avoid using green onions for pickling. They’re not suitable for long-term storage and lack the structure needed for proper marination.

🍴 How to Pickle Onions (Method & Tips)

The flavor of your pickled onions should match the dish you’re preparing:

For salads, sandwiches, and burgers: Use a mild to medium-spicy pickling brine.
For pilaf or rice dishes: A sweet-and-sour brine complements well.
For grilled meats or barbecue: Bold, tangy flavors work best.

👉 Slicing Tips:

Thin rings or half-rings are ideal for quick pickling.
Thicker slices add crunch but take a bit longer to marinate.
Avoid slicing into “feathers”—they don’t absorb the marinade evenly.
