This homemade Italian giardiniera is a colourful mix of cauliflower, fennel, carrot, celery and red capsicum, lightly cooked in a white wine vinegar brine with garlic, bay leaves, peppercorns and mustard seeds. The vegetables retain plenty of bite while absorbing the bright, aromatic flavours of the pickle.

The inspiration for making giardiniera came after a recent dinner at Bistecca in Sydney. We ordered bresaola and thin slices of pecorino with truffle honey to start, and the bresaola came with a beautiful giardiniera. The sharpness of the pickled vegetables was exactly what the rich cured meat and cheese needed.

It also immediately reminded me of my Nonna.

She used to make giardiniera too, although hers was a little different from the one we’d just eaten. The vegetables at Bistecca had a pronounced crunch, while I remember Nonna’s being slightly softer, as though the vegetables had been briefly cooked before being preserved.

That’s the style I’ve made here. The vegetables are briefly blanched directly in the vinegar brine, so they lose their rawness without becoming soft. I also added fennel, which brings a subtle sweetness and aniseed flavour and makes this homemade version a little more interesting than the jars you typically find at the supermarket.

What Is Giardiniera?

Giardiniera is an Italian preserve made from mixed vegetables stored sott’aceto — under vinegar. Its name comes from the Italian word giardino, meaning garden, which is rather fitting for a jar packed with colourful vegetables.

There isn’t one definitive combination of vegetables. Cauliflower, carrots, celery, capsicum and fennel are all used, along with other vegetables depending on the recipe and what is available.

Italian giardiniera shouldn’t be confused with Chicago-style giardiniera. The latter is generally chopped much more finely, contains considerably more chilli and is typically packed in oil. This recipe is firmly in the Italian tradition: larger pieces of vegetables preserved in a simple vinegar brine.

Ingredients You’ll Need

Cauliflower: Cut the cauliflower into small, rustic florets rather than making every piece perfectly uniform. You want them small enough to pickle easily but substantial enough to retain some texture.

Carrots: Cut into rounds approximately 5 mm thick. They remain firm after blanching and add both sweetness and colour.

Celery: Slice the celery diagonally into fairly substantial pieces. Its fresh flavour and slight bitterness work particularly well against the vinegar.

Fennel: One of my favourite additions to this giardiniera. Its natural sweetness and subtle aniseed flavour are wonderful with Italian cured meats and give the finished pickle a little more character.

Red capsicum: Adds sweetness and a beautiful hit of colour amongst the paler vegetables. I prefer broad slices rather than small pieces for a more rustic finish.

White wine vinegar: The backbone of the pickling liquid. It’s diluted with an equal quantity of water so the finished giardiniera is pleasantly sharp without the vinegar overwhelming the vegetables.

Garlic: Whole peeled cloves gently flavour the brine without dominating it.

Bay leaves: Add a subtle savoury aroma as the giardiniera sits.

Black peppercorns: Left whole to slowly infuse the pickling liquid.

Yellow mustard seeds: These add gentle warmth and another layer of flavour without making the giardiniera taste noticeably of mustard.

Whole chilli: One small chilli gives the brine a subtle warmth rather than making the vegetables hot.

Sea salt and caster sugar: Salt seasons the pickle, while a small amount of sugar rounds out the acidity. This isn’t a sweet giardiniera.

Pro Tips for the Best Italian Giardiniera

Keep the vegetables fairly chunky. Giardiniera should have plenty of texture, so avoid cutting the vegetables too finely. Rustic pieces also give the finished jars a much more homemade look.

Don’t overcook the vegetables. You’re only looking to take away their rawness, not cook them until tender. They will continue to change slightly as they sit in the vinegar brine, so they should still have a good amount of bite when they go into the jars.

Give it time before serving. You can eat the giardiniera after 24 hours, but I prefer it after three to five days. The vegetables become more flavourful as the garlic, bay leaves, peppercorns, mustard seeds and chilli infuse the brine.

Keep the vegetables submerged. Once the jars are in the refrigerator, make sure the vegetables remain beneath the pickling liquid. This also helps them pickle evenly.

Add the olive oil at the table. Keep the giardiniera in its vinegar brine and drain only what you need. A drizzle of good extra virgin olive oil just before serving rounds out the acidity beautifully without dulling the freshness of the vegetables in the jar.

How to Serve Giardiniera

Giardiniera really comes into its own alongside rich foods, where its acidity provides some welcome contrast.

My favourite way to serve it is very simply. Take as much as you need from the jar, drain it well and pile the vegetables onto a small platter. Drizzle with good-quality extra virgin olive oil just before taking it to the table.

It’s particularly good alongside bresaola, prosciutto, salami and other Italian cured meats, or with cheeses such as pecorino and Parmigiano Reggiano. Add some crusty bread or my Mediterranean Vegetable Focaccia and you have the beginnings of a very easy antipasto spread.

If you’re putting together a larger Italian-style spread, my Stracciatella Cheese with Tomato Confit would be lovely alongside it too. The creamy cheese, sweet tomatoes and sharp giardiniera all bring something quite different to the table.

How to Store Homemade Giardiniera

This recipe is made as a refrigerator pickle rather than a shelf-stable preserve.

Once the jars have cooled completely, keep them refrigerated with the vegetables submerged beneath the vinegar brine. Stored this way, the giardiniera will keep for up to 3 weeks in the refrigerator. Always use a clean utensil when removing vegetables from the jar and discard the giardiniera if you notice any signs of spoilage.

I prefer to store the giardiniera entirely in its pickling liquid rather than adding olive oil to the jar. When serving, simply drain the amount you need and finish it with extra virgin olive oil. This keeps the vegetables tasting fresh and tangy while still giving you that lovely richness from the oil when you eat them.

Frequently Asked Questions

Is Italian giardiniera the same as Chicago giardiniera?

No. Italian giardiniera is traditionally a mixture of vegetables preserved in vinegar and served as an antipasto or accompaniment.

Chicago-style giardiniera developed into a different condiment. The vegetables are generally chopped much more finely, chilli is more prominent and the mixture is typically packed in oil. It’s particularly well known as an accompaniment to Chicago Italian beef sandwiches.

Should giardiniera vegetables be crunchy?

The texture can vary depending on how the giardiniera is made.

Some versions preserve the vegetables with plenty of raw crunch. In this recipe, the vegetables are briefly blanched in the hot vinegar mixture. This gives them the slightly more tender texture I remember from my Nonna’s giardiniera while still leaving plenty of bite.

Why are the vegetables blanched in vinegar rather than water?

Blanching the vegetables directly in the vinegar and water mixture begins seasoning and pickling them immediately. The different vegetables are cooked separately because they don’t all need the same amount of time.

The carrots and cauliflower need a little longer, while the celery and red capsicum need only a very brief blanch.

Can I use different vegetables?

Yes. Giardiniera is naturally adaptable and traditionally varies according to the vegetables available.

That said, I particularly like the balance in this combination. Cauliflower provides substance, carrot and capsicum bring sweetness, celery gives freshness and fennel adds a distinctive aromatic flavour.

Do I need to add olive oil?

Not to the jar.

I store this giardiniera in its vinegar brine and add extra virgin olive oil when serving. Drain the vegetables well first, then drizzle over the oil just before bringing them to the table.

How long should giardiniera sit before eating?

Give it at least 24 hours in the refrigerator before eating so the vegetables have time to absorb the flavours of the brine.

It’s even better after three to five days, when the garlic, bay, peppercorns, mustard seeds and chilli have had more time to flavour the pickle.

Final Thoughts

I started making this giardiniera because of something delicious I ate at Bistecca, but somewhere along the way it became much more about remembering my Nonna’s version.

The two aren’t identical. The restaurant giardiniera had a much firmer crunch, while the vegetables I remember from Nonna’s were slightly softer. Briefly blanching them in the vinegar brine gave me exactly the texture I was looking for: still plenty of bite, but unmistakably pickled rather than raw.

I particularly love the fennel in this version. Along with the cauliflower, carrot, celery and red capsicum, it makes a beautiful rustic mixture both in the jar and piled onto a platter.

For me, that’s exactly where this giardiniera belongs: drained, drizzled with good extra virgin olive oil and put on the table alongside some cured meat, cheese and bread.
