How to Make Cucumber and Red Onion Pickles at Home

Preserving vegetables through pickling is an age-old method that not only extends the shelf life of produce but also adds a delightful burst of flavor to your meals. One such popular and easy-to-make pickle combination is cucumber and red onion pickles. This tangy, crunchy, and slightly sweet treat can enhance the taste of sandwiches, burgers, salads, and more. Here’s a step-by-step guide to help you make delicious cucumber and red onion pickles at home.


For making cucumber and red onion pickles, you will need the following ingredients:

  • 2 medium cucumbers, thinly sliced
  • 1 large red onion, thinly sliced
  • 1 cup white vinegar
  • 1 cup water
  • 3 tablespoons granulated sugar
  • 2 tablespoons salt (preferably pickling salt or kosher salt)
  • 1 teaspoon mustard seeds
  • 1 teaspoon black peppercorns
  • 1 teaspoon dill seeds
  • 1-2 garlic cloves, smashed (optional)
  • Fresh dill sprigs (optional)


To make cucumber and red onion pickles, gather the following equipment:

  • Medium-sized mixing bowl
  • Cutting board and sharp knife
  • Measuring cups and spoons
  • Small saucepan
  • Clean glass jars with lids (Mason jars are ideal)


Step 1: Prepare the Vegetables

Start by thoroughly washing the cucumbers and red onion under running water. Use a sharp knife to thinly slice the cucumbers and red onion into uniform circles. You can use a mandoline slicer if you prefer even thinner slices.

Step 2: Create the Brine

In a small saucepan, combine the vinegar, water, sugar, and salt. Bring the mixture to a simmer over medium heat, stirring occasionally until the sugar and salt are completely dissolved. Once dissolved, remove the saucepan from the heat and allow the brine to cool slightly.

Step 3: Pack the Jars

Place the sliced cucumbers and red onion into the clean glass jars, layering them evenly. If desired, add smashed garlic cloves and fresh dill sprigs for extra flavor. Sprinkle the mustard seeds, black peppercorns, and dill seeds over the vegetables in each jar.

Step 4: Add the Brine

Carefully pour the warm brine over the vegetables in each jar, ensuring that the cucumbers and red onions are fully submerged. Use a spoon or fork to gently press down on the vegetables to release any air bubbles. Fill the jars with brine, leaving about 1/2 inch of headspace at the top.

Step 5: Seal and Refrigerate

Secure the lids tightly on the jars. Allow the jars to cool to room temperature before transferring them to the refrigerator. Let the pickles marinate for at least 24 hours to develop their flavor. For best results, allow them to pickle for 3-5 days before consuming.

Storage and Usage Tips

Refrigerated cucumber and red onion pickles can last for up to 2 months, though they are usually consumed much sooner due to their delicious taste! Use them as a topping for burgers, hot dogs, sandwiches, tacos, or simply enjoy them as a crunchy snack.


Making cucumber and red onion pickles at home is an easy and rewarding process that results in a versatile and flavorful condiment. By following these simple steps, you can enjoy your homemade pickles in a variety of dishes, adding a refreshing and tangy touch to your culinary creations. Happy pickling!
