Essential Ingredients for the Recipe
To create these delectable pickled onions, you’ll need the following essential ingredients:
Ingredients:
- 1 medium red onion, thinly sliced (about 1½ cups)
- ½ cup apple cider vinegar (or white vinegar)
- ½ cup warm water
- 1 tbsp sugar (or honey/maple syrup)
- 1½ tsp kosher salt
- 1 tsp whole peppercorns (optional)
- 1 bay leaf (optional)
- 1 clove garlic, smashed (optional)

Main Ingredient 1: Red Onion
The star of the show! Red onions deliver a sweet, satisfying crunch when pickled. If you find red onions too pungent, you can substitute with white or yellow onions, but the unique color and flavor of red onions truly shine in this recipe.
Main Ingredient 2: Apple Cider Vinegar
This ingredient not only provides the tang necessary for pickling but also contributes various health benefits. If apple cider vinegar isn’t available, you can substitute with white vinegar or rice vinegar, though the flavor may vary slightly.
Main Ingredient 3: Sugar and Salt
Sugar and salt are essential for balancing the acidity of the vinegar. Adjust the amounts according to your taste. For a healthier option, you can use honey or an alternative sweetener of your choice.
Ingredient Preparation
Step 1 – Slice the Onions
Begin by thinly slicing the large red onion. A mandoline slicer can help achieve uniform slices and minimize effort. The thinner the slices, the better they’ll absorb the pickling brine.
Step 2 – Prepare the Brine
In a medium saucepan, combine the apple cider vinegar, water, sugar, salt, black peppercorns, and any optional ingredients. Bring it to a gentle simmer over medium heat, stirring gently until the sugar and salt dissolve.
Step 3 – Combine and Cool
Once your brine is prepared, pack the sliced onions into a clean jar. Pour the hot brine over the onions, ensuring they are fully submerged. Allow the mixture to cool to room temperature before sealing the jar and storing it in the fridge.
Step-by-Step Cooking Instructions
Step 1 – Initial Preparation
Before you start cookin’, gather all your ingredients and necessary kitchen tools. A cutting board, knife, a saucepan for the brine, and a clean jar for storage are essential to streamline the process.
Step 2 – Ingredient Assembly
Layer the thinly sliced onions snugly in your jar. This will ensure each slice is evenly coated in the pickling brine. Don’t be shy—pack them in tightly!
Step 3 – Cooking and Finishing Touches
Pour the heated brine over the onions, making sure they are completely covered. If you’ve included optional ingredients like crushed red pepper or thyme, give the mixture a gentle swirl. Let them sit until cool, then store in the refrigerator, where the flavors will develop over time.
Tips for an Even Tastier Version
Adding Extra Ingredients
Consider throwing in additional flavors! Other vegetables such as carrots or cucumbers can also be pickled along with the onions. Experiment with different herbs or spices like dill, cumin, or even spices from around the world to create your twist.
Techniques to Enhance Flavor
Let your pickled onions marinate for at least 24 hours for the best flavor, but they can be enjoyed within an hour! The longer they sit, the more intense the flavor.
Adjustments for Preferences
Cater to special dietary needs by ensuring that all ingredients are gluten-free and vegan. Play around with spicy elements for a bolder flavor, or reduce the sugar for a tangier taste.
