Ingredients for Pickled Onions
The key to a good pickled onion is the balance between acidity, sweetness, and spices. With basic and easy-to-find ingredients, you can prepare a jar of pickled onions that will enhance any dish.

Main Ingredients and Their Function

• Red onions (2 large): They are the star of the recipe. They add a vibrant color and a milder taste than white onions.

• Apple cider vinegar or white vinegar (1 cup): This is the essential ingredient for pickling. Apple cider vinegar has a milder and fruity flavor, while white vinegar provides more acidity and preserves the pink color of the onions.

• Water (½ cup): Helps to soften the intensity of the vinegar.

• Sugar (1 tablespoon): Balances the acidity and enhances the flavor.

• Salt (1 teaspoon): Enhances flavors and aids in preservation.

• Bay leaf (1 leaf): Adds a subtle earthy aroma.

• Dried oregano (½ teaspoon): Adds a herbal note that complements the flavor of the pickled onions.

• Garlic (1 clove, sliced): Adds depth and a mild spicy kick.

• Whole peppercorns (½ teaspoon): Adds a spicy touch without overwhelming the flavor.

Substitutions and Tips
If you want to experiment with this recipe, here are some substitution options:

• If you don’t have red onions, you can use white onions or shallots. The flavor will be a bit stronger, but it will still be delicious.

• For a sweeter version, you can use honey instead of sugar.

• If you prefer a more aromatic pickle, you can add cloves, mustard seeds, or even a pinch of cinnamon.

• If you like it spicy, add fresh or dried chili slices.

The best part of this recipe is that you can adjust it to your liking. Don’t be afraid to try different combinations until you find the one you love most.

Kitchen Tools You’ll Need
You don’t need any special equipment to make this pickled onions recipe, but there are a few tools that will make the process easier.

Must-Have Basics

• Glass jar with airtight lid: Essential for storing the pickled onions. Glass doesn’t react with vinegar and keeps the flavor pure.

• Medium saucepan: To heat the vinegar and spices mixture.

• Sharp knife and cutting board: To slice the onions thinly.

Useful Extras

• Mandolin: If you want perfectly uniform onion slices, this tool will be very helpful.

• Strainer: Useful if you decide to infuse the vinegar with spices and want to strain them before pouring the mixture over the onions.

Having your tools ready before you begin will make the preparation quick and easy.

How to Make Pickled Onions Step by Step
This process is very simple and requires only a few steps. In less than 10 minutes, you’ll have a jar ready to marinate and enjoy.

Step 1: Prepare the Onions
Start by peeling the onions and slicing them thinly. You can use a sharp knife or a mandolin to ensure that all the slices are of the same thickness.

Place the slices into a clean, dry glass jar. Don’t press them too tightly, as you want the liquid to cover them completely.

Step 2: Heat the Pickling Mixture
In a medium saucepan, add the vinegar, water, sugar, salt, bay leaf, oregano, garlic, and peppercorns. Bring the mixture to a medium heat and stir occasionally until the sugar and salt dissolve completely.

Once the mixture begins to simmer gently, remove it from the heat.

Step 3: Pour and Let Rest
Pour the hot mixture over the onions in the jar, ensuring it covers them completely.

Let the pickled onions rest at room temperature until they cool completely. Then, seal the jar and store it in the refrigerator.

Although you can taste it after a couple of hours, for the best flavor, it’s recommended to let it marinate overnight. The longer it sits, the more intense the flavor will be.

This basic pickled onion recipe is one that you can customize to your tastes. It’s quick, easy, and the perfect addition to give any dish a special touch. In the next section, I’ll share some tips to make your pickles last longer and answer common questions.

Tips for Perfect Pickled Onions
While making pickled onions is easy, there are some details that can make the difference between a good and a spectacular result.

How to Prevent Onions from Becoming Too Soft
If you want the onions to retain their crunchy texture, follow these tips:

• Don’t use boiling water: The vinegar and water mixture should be hot, but not boiling when poured over the onions. If the liquid is too hot, the onions will lose their firmness.

• Use fresh, firm onions: If the onions are soft before cutting, they probably won’t retain their texture after pickling.

• Don’t store them for too long: While pickled onions last several weeks, they will be crunchier in the first few days.

How to Enhance the Flavor of the Pickled Onions
While the base recipe is delicious, there are ways to make the pickled onions even more flavorful:

• Let it rest longer: Although you can taste the onions after two hours, the flavor will be much stronger if you let it sit for 24 hours or more.

• Add more spices: In addition to oregano and pepper, you can experiment with cumin, cloves, or even a touch of ginger for a different flavor profile.

• Try different vinegars: Apple cider vinegar gives a softer, fruity flavor, while white vinegar offers more acidity. If you want something special, try red wine vinegar or balsamic vinegar.

How to Store Pickled Onions
To preserve the flavor and freshness of your pickled onions for as long as possible, it's important to store them properly.

Can You Leave Them at Room Temperature?
It’s not recommended. While vinegar acts as a preservative, pickled onions should be stored in the refrigerator to prevent fermentation and the growth of bacteria.

Refrigeration

• Optimal storage time: They’ll stay good for up to a month in the refrigerator.

• How to store: Use a glass jar with an airtight lid to prevent the vinegar smell from permeating other foods.

• When to discard: If you notice any strange smell or changes in texture, it’s better not to consume them.

Can You Freeze Pickled Onions?
Freezing is not recommended. Although you technically can freeze them, the texture of the onions will change and they’ll become mushy once thawed. For a fresh and crunchy pickle, it’s best to make small batches and consume them within the following month.

Frequently Asked Questions (FAQs)
Here are some common questions about pickled onions.

• How long does it take for the pickled onions to be ready?
  You can eat the pickled onions after two hours, but their flavor improves considerably after 24 hours in the refrigerator.

• Can I use white onions instead of red onions?

• Is it necessary to boil the pickling mixture?
  It’s not mandatory, but heating the vinegar and water helps to better infuse the flavors of the spices and ensures that the sugar and salt dissolve completely. It also helps to slightly soften the onions without losing their texture.

  Definitely! Some popular options include:

  • Thinly sliced carrots: Adds a sweet touch and extra color.

  • Sliced chilies: For a spicy pickle.
