Why You’ll Love This Pickled Onions Recipe
5 ingredients and less than 10 minutes
No canning required – just refrigerate
Keeps for weeks in the fridge
Adds bold, zesty flavor to any savory dish
Naturally gluten-free and vegan

Ingredients
- 1 large red onion, thinly sliced
- ¾ cup apple cider vinegar (or white vinegar)
- ¾ cup water
- 1 tablespoon sugar
- 1 ½ teaspoons salt
- Optional: 1 garlic clove, peppercorns, red pepper flakes, or a sprig of fresh thyme for extra flavor
Instructions
Step 1: Prep the Onion
Peel and thinly slice the red onion into rings or half-moons. The thinner the slices, the faster they’ll pickle.
Step 2: Make the Brine
In a small saucepan, combine vinegar, water, sugar, and salt. Heat over medium heat just until the sugar and salt dissolve (no need to boil). Remove from heat.
Step 3: Pickle
Place the sliced onions in a clean mason jar or heat-proof container. Pour the warm brine over the onions until fully submerged. Add any optional flavorings now.
Step 4: Cool and Store
Let the jar cool at room temperature for about 30 minutes. Then seal and refrigerate. The onions will turn a beautiful pink and be ready to eat in about 1 hour—though they’re best after a few hours or overnight.
