Giardiniera Italian-style mixed pickled vegetable recipe

 These are the colorful, tangy mixed vegetable pickles graced with olive oil that show up as part of your antipasto plate before the main food arrives in Italian restaurants. They are easy to make and delicious.

The oil in this recipe is used more as a flavoring than as a preservation factor, so be sure to use a good quality extra-virgin olive oil. Also, the oil will congeal in the refrigerator, so let the giardiniera come to room temperature for the olive oil to re-liquify before serving.

Ingredients

  • 1 small cauliflower head (about 1 pound)
  • 3 celery ribs
  • 1 red bell pepper (and/or yellow or green peppers)
  • 6 carrots
  • 1 onion (white or yellow)
  • 1 3/4 cups white wine vinegar
  • 1 1/2 cups water
  • 2 teaspoons kosher salt (or other non-iodized, medium grain salt)
  • 1 tablespoon sugar (or 2 teaspoons honey)
  • 1 to 2 cloves garlic (peeled and lightly smashed)
  • 1 bay leaf
  • Optional: 1 small, hot chile pepper
  • 1/2 teaspoon mustard seeds
  • 4 to 6 black peppercorns
  • 3 tablespoons extra-virgin olive oil

Steps to Make It

  1. Gather the ingredients.

  2. Wash the cauliflower, celery, and bell pepper. Remove the solid core from the cauliflower and break the rest up into approximately 1-inch florets.

  3. Remove the stem, seeds, and any white pith from the red bell pepper. Chop the celery and pepper into 1-inch pieces. Alternatively, cut the peppers into strips.

  10. Remove the pot from the heat. Use a slotted spoon to transfer the vegetables to the jar.

  11. Pour the hot brine over the other ingredients. You want the vegetables and spices to be completely immersed in the liquid, but there should still be a 3/4-inch headspace between the surface of the brine and the rim of the jar.

  12. Pour the extra-virgin olive oil on top of the brine. There should be just enough oil to completely cover the surface of the brine.

Pickling Equipment Warning

Do not use copper, brass, galvanized, or iron utensils/pots when pickling food. These metals can react with acids or salts and cause undesirable color changes and/or form toxic compounds in the pickles.

Tip

  • The giardiniera will keep in the refrigerator for at least 3 months. If you want to can it for longer storage at room temperature, leave out the layer of olive oil and process in a boiling water bath for 15 minutes (adjust the canning time if you live at a high altitude).

Recipe Variation

  • Note that you could also use distilled white vinegar instead of white wine vinegar, but the flavor won't be as good. Either way, what you're after is not only acidity to safely preserve the food, but also a clear brine that shows off the colors of the pickles.
