The Pickle-y Italian Condiment You Can Make at Home
This is an easy homemade giardiniera, an Italian condiment with pickled cauliflower, carrots, celery, and bell peppers. You’ll want to put on everything—sandwiches, salads, cheese boards, and even pizza.
I’m far from a professional canner, but I do love picking a few worthy vegetables to can during the summer so I can enjoy delicious canned produce for a few months after. This homemade giardiniera tastes so wonderful and can be used as a bright condiment on homemade pizza, sandwiches, and salads. They are also great addition to cheese platters.
My version is spicier and sweeter than most store-bought ones I’ve had. Pop open a jar and I doubt it’ll make it through the week—I find myself snagging a piece or two every time I open the fridge!
What is Giardiniera?
Giardiniera means “gardener” in Italian. As you may guess, it’s essentially a garden in a jar—you can use a wide range of vegetables. I like to use cauliflower, carrots, celery, and peppers.
The pickling liquid to make giardiniera can take many forms. This recipe uses a mix of red pepper flakes, jalapeños, sugar, and salt so it is spicy and sweet. Some versions have oil in them, but I prefer to drizzle in oil into the jars or over the vegetables after canning and after I open the jars to eat.
Best Vegetables for Giardiniera
Any hearty vegetable can be turned into giardiniera. For a good base, I like cauliflower since it stays crunchy and doesn’t shrink much when pickled. Other than that, any mix of peppers, cabbage, and even olives work well.
Rinse and cut your vegetables into small pieces—I recommend a specific size for each on the ingredient list. You don’t want any huge pieces. You can chop the vegetables more finely—you may only get 4 pints, instead of 6 pints, as more vegetables will fit in each jar.

Heat the jars:
If you plan to store the giardiniera outside the fridge for any length of time, you will need to heat your jars in a hot water bath after filling them. This recipe will yield 6 pint jars.
To heat the jars for canning, place the jars in a large canning pot. Fill the pot with warm water so that it comes up at least 1 inch above the jars. Bring to a boil, then keep at a gentle simmer until it’s time to can.
Wash the lids and bands in hot, soapy water.
Make the brine and simmer vegetables:
Add the vinegar, sugar, water, salt, fennel and celery seeds, and red pepper flakes into a large pot set over high heat. Stir and simmer until sugar is dissolved and mixture is boiling. Add the vegetables to your pickling mixture and simmer for 30 seconds. Then remove from heat.
Fill the jars:
Remove the jars from the canner, dumping the hot water inside the jars back into the canner. Set them on a clean dish towel on the counter.
Divide the bay leaves, garlic, and peppercorns among the jars.
Ladle the vegetables into the prepared jars, leaving 1/2 inch of space between the vegetables and the top of the jar. Then, pour the pickling liquid into each jar, covering the vegetables—keep 1/2 inch of headspace.
Wipe the rims clean with a paper towel. Place a clean lid on each jar and secure finger-tip tight with the band.
Process in hot water bath:
If you plan to store the giardiniera outside the fridge, you will want to process the filled jars in a hot water bath.
Return the filled jars to the same canning pot with its already hot water. The water level should be at least 1 inch above the top of the jars; add more water to the canner, if needed. Bring the water to a full rolling boil for 10 minutes.
If you live at high altitude, add 5 to 10 minutes to the processing time. Over 5,000 feet elevation? Process the jars for 20 minutes. When in doubt, process for longer.
Cool and store:
If you are not processing these jars in a water bath, they will keep in the fridge for about 3 months.
Remove the jars from the pot using tongs or a jar lifter. Let cool slowly to room temperature. Once cooled, be sure to check seals on jars . The lid—not the metal band—should be drawn down into the jar because of the vacuum seal. You can take the metal bands off and carefully turn the jars upside down. A well-sealed jar won’t leak.
Store sealed jars in a cool, dry place for up to 1 year, but for the best flavor and texture, enjoy the giardiniera within 6 months. Once opened—you can enjoy them after 4 days—refrigerate for up to 2 weeks.
